About The Position

You will own features end to end, from conception to production, across our gateway infrastructure, enterprise deployments, and agentic systems. The work leans backend and infra, but nothing is off limits: when the product needs a better UI you build it, and when a connector breaks during a security review you fix it.
Claude and Codex are your primary working environment, and you use a fleet of agents to move faster than a team this size has any right to. Agents write much of the code and review PRs, so your real job is the judgment they cannot make: shaping the problem, making architecture, product, and UX calls, hardening enterprise paths, designing connectors, protecting security-sensitive surfaces, and catching generated code that is quietly wrong. Roles are blurred and we ship within hours, and you will learn directly from the founders and from customers.
We hire across levels, from strong early-career builders to seasoned engineers, and we set level and pay to match. What matters most is judgment, range, and how fast you ship.

Requirements

• Builder with a track record of shipping to real users (product, internal tool, open-source project, or serious side project).
• Ship and iterate without waiting for specs or approvals.
• Strong fundamentals and learn fast.
• Care about product value and customer needs over technical purity.
• Take infra seriously, thinking about blast radius, trust boundaries, and impact on customer agents.
• Ability to read unfamiliar code, reason from first principles, and explain tradeoffs.
• Comfortable across the stack (TypeScript, Python, CockroachDB) or ability to pick up new languages, protocols, and domains fast.
• Excited to build with agents and learn when they help and when they hide a problem.
• Already build with AI every day and want room to move without heavy process.

Nice To Haves

• Developer-facing products, protocol or gateway work, or infrastructure at scale.
• Background in security, identity, or permission systems.
• Contributions to open source, MCP servers, or agentic frameworks.
• Design sensibility: engineers who care about design, designers who think about infrastructure.

Responsibilities

• Own features end to end, from conception to production, across gateway infrastructure, enterprise deployments, and agentic systems.
• Build product UI when needed.
• Fix connectors during security reviews.
• Shape problems, make architecture, product, and UX calls.
• Harden enterprise paths.
• Design connectors.
• Protect security-sensitive surfaces.
• Catch generated code that is quietly wrong.
• Learn directly from founders and customers.

Benefits

• Competitive compensation and meaningful equity.
• Unusual scope and ownership of features that ship to enterprise customers.
• Building and deploying agents on the same platform we sell.
• Direct access to the founders, customer context, and product direction, with mentorship as you grow.
• Health benefits, on a team that puts family and health first.
