* Build integrations for telephony, WebRTC, real-time audio processing, and external AI/speech services.
* Ship end-to-end product features across backend systems and user-facing web experiences when required.
* Improve platform reliability and performance: monitoring, tracing, autoscaling, and failure recovery.
* Address real-time interaction challenges such as turn-taking, interruptions, responsiveness, and graceful handoff to humans.
* Partner with product and design to deliver voice experiences that feel polished and human.
**** What you bring to the role
***** Solid backend fundamentals with experience designing APIs, async systems, and scalable integrations.
* Hands-on experience with real-time systems (WebRTC, Web Sockets) or telephony protocols.
* Product-driven engineering mindset — you ship user-facing features and care about UX quality.
* Ability to debug and optimize latency and reliability issues in production systems.
* Enjoys cross-functional collaboration with product, design, and ML/speech teams.
**** Basic qualifications
***** 3+ years building production software, with significant backend engineering experience.
* Experience with real-time or event-driven systems (WebRTC, SIP, streaming APIs).
* Proficiency in Python or equivalent backend languages and async architectures.
**** Preferred qualifications
***** Experience with telephony stacks, SIP, media servers, or speech/ASR/TTS integrations.
* Familiarity with LLMs, speech models, or conversational AI production infrastructure.
* Experience on fullstack teams shipping both backend and frontend user experiences.
* Expertise in diagnosing performance and reliability issues under real-time constraints.
