Senior / Staff Fullstack Engineer

At the company, we're building the product development system for teams and agents. AI is fundamentally changing how software gets built, and we’re shaping the tools this new era requires.

Founded in 2019, the company has become the platform of choice for more than 50,000 companies (including OpenAI, Coinbase, and Ramp) to plan, build, and ship their products. Today, our team is distributed across North America, Europe, and Australia, and we’re continuing to grow internationally. What unites us is relentless focus, fast execution, and a deep care for software craftsmanship.

As a small team, we’re all generalists and constantly picking up new challenges. When it comes to code, we’re looking to work with experienced people who can pick a problem and solve it. We use TypeScript and build scalable systems so we can continuously make progress on a solid foundation. We don’t expect you to have a background in everything we use, but we do expect strong JavaScript fundamentals and a background working with React and TypeScript.

Location & work mode

The company is a remote-first company, with optional co-working offices in San Francisco, New York, and London. This role is open to candidates based in North America and Europe. You can work from most timezones within these regions. We value deep focus and async collaboration, with intentional moments to connect in person through team off-sites, optional co-working, and occasional travel.

What you'll do

• Build new user-facing features with everything from database models to GraphQL resolvers and UI components

• Optimize our data synchronization stack by applying better serialization protocols

• Add real-time collaborative editing to our content editor

• Improve performance by profiling and tweaking virtualized list rendering

• Add analytics, monitoring, and alerts to our service so that we can better respond to operational incidents

• Open-source any non-trivial innovations that come out of our work on the product

• Redefine best-in-class software development processes so that we can build a purpose-built product.

What we're looking for

• 5+ years of experience building customer-facing products at a high-quality software company

• Strong React and TypeScript fundamentals, with experience across the full stack (Browser technologies, Node, GraphQL, PostgreSQL)

• Track record of driving complex, end-to-end features (not just incremental improvements and refactors) with visible impact on the product

• Product sensibility: you care about UX, speed, and polish, and you push back when something doesn't feel right

• Comfortable working without heavy PM overhead; you can help to shape the problem, not just implement a solution

• High ownership mentality: self-directed, full-lifecycle builder who takes a feature from idea to shipped

• Thrives in a remote, async-first environment with a lean, high-output team

• Experience at a startup or a company with a genuinely high engineering bar
