[About the role]

This role is for someone who thrives at the intersection of great engineering and great product thinking. You'll design and ship robust frontend solutions, contribute to SDK development, and collaborate across teams to bring complex features to life seamlessly. Someone who takes full ownership, sweats the details, and raises the engineering culture around them will do exceptionally well here.

Strong proficiency in JavaScript/TypeScript and deep understanding of frontend architecture
Solid experience with MVVM or similar architecture patterns in production environments
Experience working with RESTful APIs, including network request lifecycle, error handling, and API versioning
Hands-on experience with authentication and session management (e.g., OAuth, token-based auth, refresh token rotation)
Experience with data synchronization strategies and offline-first design
Proven ability to review and discuss API specifications (OpenAPI/Swagger) and provide mobile/client-friendly feedback to backend teams
Proficiency with debugging tools such as Charles Proxy, Postman, or Wireshark for end-to-end issue diagnosis
Solid experience with Git and version control best practices
Experience with media-related frontend features
Track record of leading code reviews, mentoring junior developers, and establishing engineering best practices
Demonstrated ability to own features end-to-end from concept through deployment, collaborating closely with product managers, designers, and backend engineers

[Required Experience]

Advanced understanding of browser/platform internals, system-level APIs, and performance optimization techniques
Expertise in WebSocket technologies and real-time communication architecture design
Experience with low-latency streaming, adaptive bitrate streaming (HLS/DASH), and related protocols
Deep knowledge of audio codecs, audio processing, and audio/video synchronization techniques
Prior experience designing and implementing custom media pipelines
Experience with WebRTC or similar peer-to-peer communication technologies
Familiarity with Web Audio API or media player SDK development
Experience publishing and maintaining npm packages
Contributions to open-source frontend projects
