Senior Software Engineer (Web SDK Platform)

The Role

We are looking for a Senior Software Engineer to serve as a technical pillar for our client-side document SDK. This is not a standard UI/UX role; you will be architecting the engine that powers document rendering, programmatic manipulation, and collaborative workflows for millions of users.

As a senior leader on the team, you will steward our Core minified engine while maintaining our open-source UI layer. You will be responsible for navigating deep technical ambiguity, writing comprehensive design documents, and making high-stakes trade-off decisions regarding performance, memory management, and API design. If you enjoy the challenge of working with WebAssembly, concurrent workflows (Web Workers), and complex binary file formats (PDF, DocX, XLSX), this role is for you.
