• Improve and create new lead capture domain models. • Build backend & Frontend API features and architecture. • Work cross-functionally across our platform, experience, integrations, payments and marketplace teams. • Drive performance through benchmarking and optimization • Work with a wide range of systems, processes, and technologies to own and solve problems from end to end • Collaborate closely with our leadership team including engineers, designers, and product managers to build new features and products • Uphold high engineering standards and bring consistency to the many codebases and systems you will encounter. • Create and improve lead capture tools like funnels, websites, forms, surveys, social media • Architect and build backend & Frontend APIs and features

• Create new managed compute primitives that feel first-class in Temporal Cloud: crisp abstractions, clean APIs, and an extension story across compute providers. • Design self-optimizing autoscaling systems (signals, backstops, debouncing, guardrails) that scale worker fleets safely and predictably. • Define the Open Source Server ↔ Cloud boundary for compute capabilities, keeping the architecture cohesive and maintainable. • Architect, build, and operate services on the hot path of task execution where performance and correctness are customer-visible. • Deliver real-world cloud integrations (e.g., customer-account execution): IAM boundaries, secure credentials handling, networking constraints, quotas, and failure modes. • Make operability a feature: SLOs, tracing/metrics, load and failure testing, incident reviews, and continuous hardening. • Ship end-to-end: API design, rollout strategy, backwards compatibility, and long-term maintenance. • Raise the bar through design docs, strong reviews, pragmatic technical leadership, and mentorship. • Lead through influence across teams (Server, SDKs, Security, Control Plane) to land coherent platform changes.

Title: Fullstack Software Engineer Location: San Francisco Department: Engineering Job Description: About Collective: Collective is on a mission to redefine the way businesses-of-one work. Our technology and team of trusted advisors help members achieve financial independence by taking care of everything from business incorporation to accounting, bookkeeping, tax services, and access to a thriving community, all in one integrated platform. We believe in empowering self-employed people to enjoy the same tax savings that big companies get, so they can focus on their passion, not paperwork. Featured in Forbes, Business Insider, Yahoo, Bloomberg, Financial Times, TechCrunch, and more. We are backed by General Catalyst, Sound Ventures (Ashton Kutcher and Guy Oseary), QED Investors, Google’s Gradient Ventures, Expa, and other investors who have financed iconic companies like YouTube, Substack, Twitch, Box, Hims, Instacart, and Lyft. About the role: We're hiring a Software Engineer to help build and scale the systems that power Collective's accounting product, the connection between our members' bank activity, bookkeeping, and tax outcomes. You'll work across the stack on the platform that automates reconciliation, ingests transaction data from our banking and accounting partners, and turns raw financial activity into clean, member-ready books. This is a product engineering role with real ownership, working closely with Product, Design, Operations, and our in-house accounting team to ship fast and iterate based on member and operator feedback. You'll be expected to use modern AI tools and agent-based workflows to accelerate development, improve code quality, and unlock new product capabilities. This role is ideal for engineers who are hungry to grow into broader ownership, think in terms of outcomes, and see AI as a core part of how software gets built today. What you'll do: - Build and ship features across the accounting product - from member-facing reconciliation and bookkeeping experiences to internal tooling that powers our accounting and bookkeeping operators - Work on the integration layer between Collective and our partners that includes extending APIs, handling edge cases, and improving data reliability - Improve the transaction pipeline that flows from bank feeds through our accounting platform into our data layer, including reliability, observability, and drift detection between source and destination - Own well-scoped features end-to-end with support from senior engineers to define the approach, build, deploy, instrument, and iterate - Partner with Product, Design, and Operations to translate accounting workflows into clean software, and surface engineering tradeoffs early - Use AI-powered development tools (copilots, code agents, agent workflows) day-to-day to move faster and cut manual overhead - Clear communication and collaboration skills across technical and non-technical partners - Demonstrated ability to integrate AI agents and automation into development workflows and product features What you'll bring: - 3–4 years of experience building and shipping production software in a product-focused environment - Solid fullstack engineering skills (e.g., Python, Django, React, or similar modern frameworks) - Experience integrating with third-party APIs and working with messy, real-world data - Hands-on use of AI developer tools (copilots, code agents) in your day-to-day workflow — not just experiments - Ability to take a well-scoped problem and drive it to a shipped, instrumented solution with light guidance - Good product and UX instincts to make sensible scope tradeoffs and ask the right clarifying questions before building - Clear written and verbal communication, especially when explaining tradeoffs to non-engineering partners - Familiarity with SQL and working with data warehouses (BigQuery a plus) - Interest in the accounting / fintech / payroll domain, or a track record of getting up to speed quickly in a new domain What we offer: - Hybrid Work Model: Based in San Francisco with a balance of in-office and remote flexibility. - Fresh Lunch: Provided on in-office days. - Commuter Support: $150 monthly reimbursement for transit expenses. - Health & Wellness: $200 quarterly reimbursement to support your well-being. - Time Off: Flexible PTO plus 14 company holidays. - Comprehensive Coverage: 100% medical, dental, and vision for employees; 75% coverage for dependents. - Parental Leave: 16 weeks fully paid. - Retirement & Ownership: 401k plan plus an equity package. - Team Connection: Quarterly virtual events and an annual in-person summit.
