The role

We are hiring a Senior SDK Engineer to build and own Frame.js, our TypeScript SDK and web component library that merchants use to embed compliance-aware payment flows into their products. This is a craft role. The SDK is what developers actually touch. It needs to be obvious on first read, reliable in production, and thoughtfully designed at every level of the abstraction.

What you'll do

  • Own Frame.js, the TypeScript SDK merchants use to embed identity verification, payments, and compliance flows. Build web components that handle complex compliance interactions while remaining simple to integrate. Write developer documentation, integration guides, and the examples that make adoption frictionless. Manage SDK versioning, backwards compatibility strategy, and the release process that keeps it reliable. Build internal tooling and testing infrastructure that ensures SDK quality across merchant environments. Maintain feedback loops with merchants and the Frame engineering team so the SDK evolves with real usage.

what we require

  • 5+ years of software engineering experience, with significant focus on SDK or developer tooling. Deep TypeScript and JavaScript experience. You know the language well enough to design around it. Experience building and maintaining public-facing APIs or SDKs used by external developers. A strong instinct for developer experience. You know what makes an API feel right, and what makes it frustrating. Attention to detail at the documentation level. Good code and bad docs is still a bad SDK.
  • Experience building payment, identity, or compliance SDKs is a strong plus, as is managing a public SDK through versioning, deprecation, and breaking changes. Familiarity with web components, custom elements, or shadow DOM, fintech or regulated infrastructure background, or experience with Go or Ruby on the backend complementing front-end SDK work, is also valued.

you are someone who

Sees the SDK as a product, not a wrapper. You sweat the details that make the difference between an API that clicks on first read and one that frustrates. You hold a high bar for developer experience and treat documentation as a first-class deliverable.

the fun stuff

  • $160,000 to $200,000 base + equity
  • Unlimited PTO, with trust to manage your own time.
  • A wellness budget covering dental, vision, and a free Equinox membership, plus team-led running and spin groups.
  • Daily lunch and a fully stocked snack kitchen in our Los Angeles office.
  • Apple hardware, Frame branded merch, regular company offsites, and a relocation package if you're not already local.
