• Integrate with third-party AI and media services, including LLM providers, voice services (STT/TTS), and real-time delivery infrastructure.


• Contribute to AWS infrastructure, deployment pipelines, and environment management as the platformgrowsand new capabilities are introduced.


• Partner closely with the Engineering Manager and Principal AI Engineer on architectural decisions, code review, and technical planning.


• Participate in observability, on-call practices, and operational improvements to ensure the platformremainsreliable as usage scales.

What You Will Bring

• 3+ years of full stack engineering experience with a strong backend emphasis.


• Proficiencywith modern frontend frameworks (React or equivalent) and backend technologies (Node.js and/or Python).


• Experience building, versioning, andmaintainingproductionREST APIs consumed by external teams or partners.


• Solid AWS fundamentals — Lambda, API Gateway, RDS, S3, and related services.


• A track recordof integrating with third-party APIs in production environments, including managing reliability, error handling, and graceful degradation.


• Strong communicationskills and comfort working in a small, fast-moving team across multiple concurrent workstreams.

Extra Credit

• Experience integrating with LLM APIs (OpenAI, Gemini, Anthropic, or equivalent).


• Familiarity with real-time communication systems (WebRTC,WebSockets, orLiveKit).


• Experience with voice and audio API integrations (TTS/STT).


• Background in platform, developer-tooling, or API-first product development.


• Observability experience with Datadog or equivalent tooling.
