ROLE SUMMARY :

Own the backend services that power real-time voice workflows and product APIs. This role is about low latency, high reliability, and shipping fast, with heavy use of AI-assisted coding baked into how you work every day.

Stack : Python, FastAPI, Postgres, Redis, Azure, GCP

RESPONSIBILITIES :

- Build Python services using FastAPI for customer-facing and internal APIs

- Design systems for call orchestration, routing, retries, and event-driven state handling

- Improve latency and reliability, measure p95 and p99, and ship changes that actually move those numbers

- Build robust integrations, handle edge cases well, and bring failure rates down consistently

- Own observability, get to the root of production issues quickly, and put long-term fixes in place, not just patches

MUST HAVE :

- 2 to 4 years of backend experience with Python, FastAPI is preferred

- Strong fundamentals in HTTP, WebSockets, queues, and distributed systems

- Experience building production systems that handle concurrency, scale, and failure modes without falling over

- Strong debugging, performance profiling, and database query tuning skills

- Ownership mindset, you do not wait to be told something is broken

NICE TO HAVE :

- Experience with low-latency or real-time systems, streaming, or event-driven architectures

- Voice AI exposure, including ASR, TTS, VAD, and conversation state management

- Multi-cloud experience across Azure and GCP
