About the role

Senior backend engineer role at Infer, a YC-backed startup building an AI-driven operating system for insurance agencies. Focus on real-time, low-latency backend systems, voice AI pipelines, observability, and reliability.

Responsibilities

  • Optimize end-to-end voice bot latency and turn-taking behavior across STT → LLM → TTS pipelines
  • Scale backend infrastructure to handle concurrent voice sessions reliably
  • Build test infrastructure for voice agents that makes correctness easy to verify on every PR paving the way for agent-generated patches
  • Design and maintain routing-setup tests for our voice flows
  • Run monitoring and alerting; triage production issues and close the loop back into tests
  • Enable agent-driven patching of minor production issues, with humans staying in the loop on the right things

Qualifications

  • Experience building production backend systems, ideally in real-time, streaming, or low-latency contexts
  • Hands-on experience with async/concurrent systems in python asyncio, event loops, streaming pipelines
  • Deep familiarity with one or more voice/AI building blocks: STT, TTS, LLM streaming, SIP/WebRTC or telephony
  • Proven track record optimizing latency in a production system (profiling, tracing, p95/p99 work)
  • Solid database fundamentals: schema design, indexing, query optimization, and migration discipline
  • Solid test engineering instincts: unit, integration, and end-to-end testing for systems with non-deterministic components
  • Worked with distributed tracing tools (OpenTelemetry, Sentry, Datadog APM)
  • Production observability experience instrumenting services, designing useful alerts, running incident response
  • Comfort owning a system end-to-end: design, ship, monitor, debug, iterate
  • Early-stage startup experience and the instinct to ship pragmatically
  • Contributed to open-source voice or real-time AI infrastructure
  • Direct experience with voice agents orchestration frameworks
