AI Product Engineer

[About the role]

This role is for someone who thrives at the intersection of great engineering and great product thinking. Youll 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.

• Proven experience designing and shipping SDKs, including public API design, versioning strategy, and backward compatibility
• 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
• Technical blog posts, conference talks, or other public knowledge-sharing activities
