Mission Inbox

Role Description You own every word Mission Inbox publishes and every channel it moves through. Blogs, AI-optimized articles, social, and distribution are yours end to end. You are measured on three questions, and only these three: - How do we get cited more by AI engines like ChatGPT, Perplexity, Google AI Overviews, and Claude? - How do we convert social engagement into qualified leads? - How do we build measurable pipeline through content channels? If a content activity does not move one of those three, it does not happen. Objective 1: Win AI Citations (GEO / AEO) AI engines are becoming a primary discovery layer for B2B buyers. Getting cited by them is now a distinct discipline from ranking in classic Google. It rewards different signals: extractable answers, structured data, entity authority, and being the source other sites reference. What you'll do: - Build a GEO content system on question-led articles structured for direct extraction, with clear question-based headings, concise answer blocks, defined terms, and stats with sources. - Establish Mission Inbox as a citable entity on deliverability, sender trust, and email infrastructure topics. - Track share of voice across AI engines for target queries and iterate on what actually gets cited. Why this matters: Classic SEO optimizes for a click. GEO optimizes for being the quoted authority even when there is no click. For an infrastructure company where trust is the product, being the source AI models cite compounds credibility in a way ad spend cannot. Objective 2: Convert Social Engagement Into Leads Engagement is a vanity metric until it produces a lead. Your job is not to grow the follower count. It is to build a social-to-pipeline motion. What you'll do: - Run the company and founder social presence, primarily on LinkedIn, with a distinct, contrarian, technically credible voice. - Design content that surfaces buying intent through comments, saves, DMs, and profile visits, then route that intent into the funnel. - Build repeatable formats such as teardown posts, deliverability data drops, founder POV, and customer proof. Why this matters: In B2B, the large majority of LinkedIn engagement never converts on its own because there is no capture mechanism behind it. The differentiator is not more posting. It is a deliberate path from "this was insightful" to "book a call." Objective 3: Build Pipeline Through Content Content marketing fails in most companies because it is measured on traffic instead of revenue. You will be measured on content-sourced and content-influenced pipeline. What you'll do: - Map content to the buyer journey and build assets that move deals forward: comparison pages, deliverability and ROI calculators, and technical guides sales can send. - Partner with sales to identify which content actually closes deals, then produce more of it. - Own a content attribution model so we know which channels and pieces generate pipeline. Why this matters: Bottom-of-funnel, sales-enabling content punches far above top-of-funnel volume plays for a profitable, sales-led B2B company. Your leverage is helping close the pipeline that already exists, not just filling the top. Qualifications - 2+ years producing and distributing B2B content that drove measurable pipeline, not just traffic. - Demonstrated ownership of a social channel that generated leads, with receipts. - Strong writing and editing ability, capable of technically credible content in a technical category. - Comfort with analytics and attribution. You know what a content-sourced lead is and can prove one. Bonus - Experience with GEO/AEO or early AI-search optimization. - Background in email, deliverability, martech, or developer and infrastructure tooling. - Comfortable using AI tools to scale output without producing generic slop. Not a fit if - You need a full brief to write. - You measure success by post count. - You treat engagement as the finish line.

Role Description This role spans four areas. You will rotate through and eventually own pieces of all of them. - Customer Support - Be the first human a customer talks to when something is unclear, broken, or on fire. - Resolve deliverability, configuration, and platform questions with speed and accuracy. - Manage conversations in Intercom and turn one-off questions into reusable answers. - Platform QA - Use the product the way customers do, then break it on purpose. - Catch bugs, edge cases, and confusing flows before customers hit them. - File clear, reproducible reports that engineering can act on without a back-and-forth. - Product Direction - Sit closest to the customer, which makes you a primary input to the roadmap. - Surface patterns from support conversations: what confuses people, what they ask for, what they almost churned over. - Translate raw customer signal into product feedback the team can prioritize. - Knowledge Base Creation - Build and maintain the documentation, guides, and help content that scale our answers. - Turn every recurring question into an article so the next customer self-serves. - Treat the knowledge base as a product, not an afterthought. Qualifications - Strong written communication. You will live in writing. - Genuine curiosity and a bias toward figuring things out yourself. - Comfort with ambiguity and a willingness to own outcomes, not just tasks. - Fluency in English (written and spoken). Requirements - Exposure to SaaS, email, marketing, or technical products (nice to have). - Any experience that proves you can teach yourself a complex tool (nice to have). - Spanish/Portuguese is a plus given our distributed team (nice to have). - No specific degree or years of experience required. We index on judgment, drive, and clarity of thought over credentials. Benefits - Fully remote and globally distributed. We hire for talent, not timezone. - High leverage, high trust. You get real responsibility early. - Profitable and stable. Startup pace, without the funding-cliff fear.

Role Description We are seeking a highly technical, impact-driven Senior Systems Engineer to own, scale, and protect our core email transmission infrastructure. In this role, your golden rule will be Reputation Above All. You are not just managing email lists or monitoring dashboards; you will architect and maintain the high-availability server infrastructure, Mail Transfer Agents (MTAs), and automated defensive systems that ensure our legitimate traffic hits the inbox while bad actors are ruthlessly contained. The ideal candidate bridges the gap between deep Linux systems administration, network engineering, and advanced email deliverability strategy. You will have a massive impact on the company by safeguarding our global IP/domain reputation, minimizing blast radiuses, and ensuring zero-downtime mail operations across our entire infrastructure network. Core Responsibilities - Infrastructure Management & High Availability - MTA Optimization: Maintain and configure core MTAs (Postfix, Postal) and IMAP/POP3 servers (Dovecot), ensuring graceful reloads over restarts to prevent dropping active connections. - Traffic Routing & Load Balancing: Utilize HAProxy and network routing protocols (like BGP via FRRouting) to distribute outbound traffic and architect high-volume failover mechanisms. - Redundancy & Failover: Administer backend infrastructure databases (PostgreSQL replica setups) and maintain dedicated "Block" backup/archive servers to instantly take over the workload of a failed primary "Cube" server. - Architectural Segregation: Maintain strict workload isolation across our infrastructure network—separating standard nodes for mail stacks, specialized injection nodes (Postal), and separate archiving/backup systems to prevent high-volume senders from degrading performance. - Deliverability Engine & Authentication Protocol Architecture - Protocol Enforcement: Act as the absolute technical authority on DNS and authentication setups, maintaining flawless configurations for SPF, DKIM, DMARC, and BIMI. - Traffic Throttling: Implement automated, MTA-level dynamic throttling to handle 4xx deferrals instantly, preventing a single high-volume sender from triggering global rate limits across our shared IP pools. - Warm-up Strategy: Design and guide automated IP/Domain Warm-up Plans for new infrastructure, managing incremental volume scaling over 2–4 week cycles. - Edge Security, Anti-Abuse & Incident Response - Outbound Spam Filtering: Configure and optimize Rspamd to actively scan, flag, and quarantine highly spammy content before it exits our network. - Edge Defense: Deploy automated connection-dropping systems (Fail2Ban, custom SMTP blocker scripts) to mitigate authenticated attacks, brute-force attempts, and malicious traffic. - Blast Radius Mitigation: Program and maintain a dynamic IP pooling engine ("The Penalty Box") to instantly isolate accounts displaying poor metrics (bounces, FBL spikes) away from prime Tier-1 IP pools. - Blocklist Remediation: Act as the primary responder to major DNSBL listings. Leverage log analysis to locate the root cause account, plug the security leak, and submit expert delisting requests. - Observability & Monitoring - Log Shipping Architecture: Build and manage high-performance log aggregation pipelines using Vector to ship system and MTA data into a centralized repository for real-time auditing and incident response. - Network Auditing: Utilize IPAudit and custom tools to continuously scan for bandwidth anomalies, connection spikes, or compromised user credentials. - Dashboard Management: Actively monitor ISP infrastructure portals daily along with third-party tracking tools. Qualifications - 5+ years of experience as a Linux Systems Administrator, DevOps, or Infrastructure Engineer with deep networking knowledge (TCP/IP, routing, ports, DNS management). - Expert-level proficiency configuring, debugging, and optimizing enterprise mail tools such as Postfix, Dovecot, or Postal. - Hands-on experience writing rules and maintaining mail-filtering/anti-abuse applications like Rspamd and Fail2Ban. - Proven experience building or maintaining log pipelines using Vector or similar high-scale telemetry frameworks. - Experience implementing network routing layer tools (HAProxy, FRRouting) and relational databases (PostgreSQL replication). - Strong familiarity with automated SSL/TLS certificate rotation and multi-node compliance monitoring. Requirements - Deep comprehension of the difference between Delivery (server handoff) and Deliverability (inbox placement). - Expert parsing of aggregate DMARC reports using platforms like DMARCian, Valimail, or Postmark. - Strict commitment to Acceptable Use Policies (AUP): zero tolerance for purchased/scraped lists and a firm grasp on Feedback Loop (FBL) automated triage. Key Performance Indicators (KPIs) - Global Infrastructure Spam Complaint Rate: Maintained strictly under 0.1%. - Global Hard Bounce Rate: Kept consistently below 2.0%. - Infrastructure Uptime: 99.99% availability across all outbound MTAs and mail relays. - Incident Isolation Time: Transitioning high-risk or abusive senders to the "Penalty Box" or circuit-breaking campaigns within minutes of a threshold breach. This is a highly technical systems engineering role, not a marketing or email campaign management position. To be considered, you must have hands-on experience configuring Linux mail servers at the command-line level. Please confirm upon applying that the fixed compensation range of $50,000 to $72,000 USD per year aligns with your expectations.

Role Description Mission Inbox is the infrastructure layer for B2B email at scale. We provide dedicated-IP sending infrastructure, automated DNS authentication, pre-send compliance scanning, and reputation management for B2B sales teams, agencies, and SaaS companies that depend on email deliverability as a core business function. We are at an inflection point. The product is built, revenue is growing, and the customer base is expanding. What we don't have yet is a marketing engine. That's the gap this role is hired to close — from zero. This is not a "run our marketing" role. There is no existing playbook to execute, no team to manage, and no agency doing the heavy lifting. You will be the first dedicated marketing hire at Mission Inbox. You will build the strategy, own the execution, and eventually manage the team as channels mature and headcount follows performance. The right person sees this as the defining chapter of their career — a rare chance to build a full marketing function at a technical infrastructure company with real revenue, real customers, and real upside. Our Team is distributed all over the world, we welcome talent, no matter their geography, ethnicity or religion. Qualifications - 3+ years in B2B SaaS marketing, with at least 2 years operating as an IC or small-team lead - Proven track record building pipeline from scratch — not inheriting a mature funnel - You have owned a pipeline or revenue number directly, not just an MQL target - Fluent in the full marketing stack: Attio/Hubspot, Google/LinkedIn Ads, SEO tooling (Ahrefs/Semrush), analytics (GA4, Mixpanel or equivalent) - Strong copywriter — content output is not outsourced in this role - Comfortable with technical products: you understand DNS records, email authentication (SPF, DKIM, DMARC), and why deliverability matters to a sales team - PLG experience: you have built or contributed to product-led onboarding or activation flows - Native or near-native English — written communication is a core output of this role - Comfortable being the only marketer for 12+ months before building a team - Talks in CAC, payback period, and pipeline velocity — not impressions and follower counts Requirements - Demand Generation & Paid Media: Own paid acquisition across LinkedIn, Google, and relevant niche channels. Build and iterate on audience targeting, creative, and bidding strategy — no agency dependency. Define and hit a monthly pipeline contribution target. Manage budget allocation across channels based on CAC and payback period data. - Organic Content Engine: Build a consistent content operation: blog, LinkedIn, newsletter, thought leadership. Develop and execute an SEO strategy targeting deliverability, cold email, and outbound infrastructure keywords. Write or directly manage 80%+ of content output in the first 12 months. - Website & Conversion Optimization: Own the Mission Inbox website end-to-end: messaging, structure, and conversion performance. Run continuous CRO experiments across landing pages, CTAs, pricing page, and sign-up flow. Implement and maintain tracking, attribution, and analytics infrastructure. - Product-Led Growth (PLG): Design and execute in-product marketing and activation flows for self-serve users. Build onboarding email sequences that drive feature adoption and time-to-value. Define PQL criteria and build the handoff motion to sales. - Webinars & Events: Launch and run a recurring webinar program targeting B2B sales leaders, RevOps, and agency operators. Identify and manage presence at relevant industry events. Build event follow-up nurture workflows that convert attendance to pipeline. - Nurture & Lifecycle Campaigns: Design and execute multi-touch nurture programs for MQLs, trial users, and churned accounts. Build behavioral email workflows triggered by product activity and sales signals. Own HubSpot (or equivalent) — setup, segmentation, automation, and reporting. Benefits - Base Salary: $35,000/year with a structured salary renegotiation at the end of Q1 — if results clearly show a before and after your hire, compensation moves accordingly - Equity: Discussable based on background and demonstrated results - Performance Bonus: Yearly bonus tied directly to pipeline and MRR targets - Tools Budget: Full access to the marketing stack you need — no procurement bureaucracy - Remote: Fully remote, async-first culture - Autonomy: Full ownership of budget, strategy, and tooling decisions from day one
