• Build and Ship New Products: Lead engineering efforts to take new product definitions from concept through design, implementation, and launch. You thrive in the ambiguity of early-stage product development — defining technical approaches, making fast decisions with imperfect information, and iterating rapidly based on customer feedback and market signals. • Scale What Works: Once a product finds traction, build the team, processes, and architecture to scale it. Design systems and organizations that grow without breaking — transitioning from scrappy v1 to production-grade, enterprise-ready products. • AI-First Engineering Culture: Embed AI deeply into how your teams operate. From AI-assisted code generation and automated testing to agentic workflows and intelligent automation, your teams will ensure that Chainguard leverages AI to ship faster, reduce toil, and amplify engineering talent. You stay current on the evolving AI landscape and push your teams to adopt what works. • Organizational Leadership: Build your organization from the ground up. Hire and develop ICs, Managers, and Directors who are energized by building new things and owning outcomes. Structure teams for speed and autonomy — small, vertical, full-stack teams that own their products end-to-end. • Delivery Excellence: Own quarterly outcome commitments for your organization. Ship on aggressive timelines without sacrificing quality. Establish lightweight processes that create accountability and predictability without slowing teams down. • People-First Culture: Champion servant leadership, retention, and career development across your organization. Build a culture of trust, psychological safety, and high ownership. Foster an internal promotion culture and invest in growing the next generation of engineering leaders at Chainguard. • Cross-Functional Partnership: Partner closely with Product Management, Sales, Customer Success, and other functions to ensure new products are solving real customer problems and driving business outcomes. Serve as a clear communicator of engineering progress, tradeoffs, and risks to executive stakeholders. • Technical Direction: Provide strategic technical guidance and ensure sound architectural decisions across your teams. You don't need to write code daily, but you do need to understand deeply technical trade-offs and help teams make the right calls on build-vs-buy, infrastructure investment, and system design — especially in the context of shipping new products quickly. • Hiring and Talent Strategy: Build a high-performance hiring engine for your organization. Attract and hire engineers who are energized by greenfield development and comfortable with ambiguity. Balance seniority with growth and cost efficiency as you scale. • Budget and Resource Management: Own and manage the engineering budget for your organization, including headcount, infrastructure spend, and contractor resources. Make wise investment decisions in partnership with Finance and the SVP of Engineering. • Industry Presence: Represent Chainguard externally as a thought leader in open source, cloud-native security, and engineering leadership. Build relationships and credibility in the broader engineering and security communities.

• Develop and maintain applications using the React Native framework, providing support and mentorship to more junior professionals; • Understand data web services that return JSON; • Work on version control and delivery management (deploy) using Git and other tools; • Test and monitor applications and web services using appropriate methodologies and procedures; • Stay updated on development market trends, new devices, technologies, and foundations for application development; • Perform code maintenance; • Document the code development process; • Identify bugs and work on their resolution; • Actively participate in Agile ceremonies, continually exchanging knowledge, information, and status updates; • Support technical and functional definitions grounded in business needs; • Create status reports and highlight potential issues for the Project Manager;

Role Description Mercury is QuoIntelligence's Threat Intelligence platform: it processes over 2 billion signals, tracks 400+ threat actors, and delivers finished intelligence to security teams across financial services, energy, and government in Europe. You will join a four-person engineering team, working directly with the engineering lead on Mercury and Agent Karla, an AI-powered threat analyst that runs on the Mercury engine. You will ship new features and pay down tech debt in the same week. The team treats clean, maintainable code as a prerequisite, not a nice-to-have. If you want to build a product where what you ship reaches real users quickly, where you will shape how the engineering team works as it grows, and where the domain is genuinely interesting, keep reading. What You'll Do - Design, build, and ship backend services in Python: REST APIs, web services, data processing (60% of your time). - Build and maintain basic frontend features in React and TypeScript. - Write and maintain tests at every level: unit, integration, end-to-end (Playwright or similar). - Own CI/CD pipelines, code quality tooling, and static analysis. - Work with data: SQL queries, data modeling, domain modeling, and visualization. - Collaborate across teams, asking for help when stuck and proactively helping others. AI-First in Engineering We want AI to be part of QuoIntelligence’s engineering operating model. We expect engineers to use AI tools like Cursor by default across design, coding, debugging, testing, and documentation. This role is not about casually using AI for convenience. It is about using AI to materially increase speed, leanness, and impact. - Use AI to turn engineering leverage, shorten delivery cycles, and focus on high-value problems. - Strong judgment in using AI, understanding risks, and applying pragmatic safeguards. - Help re-engineer team workflows, build repeatable standards, and better tooling. - Coach teammates less familiar with agentic coding and drive AI adoption. What You'll Bring Must-haves: - AI-assisted development: actively use AI tools (e.g. Cursor) and evaluate their output critically. - Strong Python backend experience: designed and shipped production APIs, web services, and data processing systems. - Working familiarity in React and TypeScript: can build and maintain basic frontend features. - Solid testing discipline: unit, integration, and e2e testing are part of your work. - CI/CD and code quality tooling experience: set up or maintained pipelines. - Data proficiency: SQL, data modeling, and comfort with data analysis and visualization. - Clean code habits: produce readable, maintainable, and extendable code. Nice-to-haves: - Go or additional programming languages. - UX and design principles knowledge. Your First 90 Days - Month 1: By day 30, have a working mental model of Mercury's architecture. - Month 2: Own a significant feature end-to-end and start reshaping something. - Month 3: An engineering practice or system you built is now part of the team's workflow. What We Offer - Full ownership from day one. - Interesting domain: Unified Risk Intelligence solution with an AI-agentic product. - Remote with autonomy: small team, low bureaucracy, high trust. - Shape the engineering culture as the team grows. - AI-native workflow: Cursor is the standard tool. FAQ - How small is the engineering team? Four engineers (including the engineering lead). - Do I need cybersecurity experience? No, strong engineering fundamentals are what matter. - What is the tech stack? Python (backend), React/TypeScript (frontend), Playwright (e2e testing). The Process - Recruiter Interview - AI Fluency Interview - Team Interview - Live Coding - Offer
