Job description

Specifics About 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.

Why Frame:

Frame is a compliance infrastructure company powering payments for complex, highly regulated industries. We enable businesses to move money with confidence by embedding compliance and payments into a single, intelligent platform. Our ambition is to become the infrastructure layer that regulated businesses rely on to operate, scale, and access services globally.

At Frame, how we build matters as much as what we build. We're headquartered in Los Angeles with a globally distributed team. We're committed to running an inclusive and accessible hiring process. If you need any adjustments along the way, let us know.

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

You’ll Be Successful If:

• You have experience building payment, identity, or compliance SDKs is a strong plus
• You come with experience managing a public SDK through versioning, deprecation, and breaking changes.
• You bring deep familiarity with web components, custom elements, or shadow DOM
• You have experience with a fintech or regulated infrastructure background
• You have experience with Go or Ruby on the backend complementing front‑end SDK work
• You ees 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

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans. If you would like more information about how your data is processed, please contact us.
