Software Engineer, Foundation

In short: We're looking for a Software Engineer to join our foundation team with a focus on mobile. You don't need to have years of experience in platform engineering But, you do need to have shipped real production software, to care about how things are built, and to already be working with agentic coding tools every day.

Responsibilities

Mobile foundation. The core of our Flutter app: shared components, the design system, state management, performance, and the tooling around it. You'll extend it, keep it healthy, and make it obvious for product teams to use correctly.; Agentic and AI infrastructure. MCP servers, our background agent platform, evals and feedback loops, and the integration of agentic tooling into our day-to-day workflow. A research background isn't required; a serious interest in agents as an engineering discipline is.; Developer experience. CI/CD, release tooling, and the feedback loop between writing code and seeing it live. Much of this work starts by noticing the same friction three times and deciding to remove it.; Product features. Shipping user-facing work alongside platform work, both to move the product and to stay honest about what it's actually like to build on our foundation.; Reliability and maintenance. Keeping what exists dependable, so 25+ engineers can build on it without thinking about it.

Requirements

A few years of production experience building mobile (we use Flutter and Dart) or web applications; Daily use of agentic coding tools (Claude Code, Codex, or similar) and opinions on where they work well, where they don't, and how to work around it; An eye for design. You notice when spacing is inconsistent, when an animation feels wrong, when a component is close but not right; Clear communication in English and a genuine preference for improving systems that slow other people down, whether or not your name ends up on a shipped feature

Nice to have

Built mobile apps with Flutter; Worked with Golang (or similar backend language); Anything you've built with agents, MCP, or evals.
