What You’ll Be Doing

  • Develop and maintain Python-based backend services for real-time voice products
  • Work directly with LiveKit for audio/video streaming and real-time communication
  • Build and optimize speech-to-speech pipelines (streaming audio, events, state handling)
  • Integrate AI components (ASR, TTS, LLMs) into real-time systems
  • Design and improve low-latency, scalable architectures
  • Debug performance issues related to streaming, concurrency, and networking
  • Collaborate closely with founders on core technical decisions
  • Take ownership of features from development to production

Requirements

  • Strong experience with Python
  • Experience working with real-time systems, streaming, or WebRTC-based technologies
  • Hands-on experience with LiveKit (or similar real-time communication frameworks)
  • Solid understanding of async programming, concurrency, and event-driven architectures
  • Experience with APIs, background workers, and production deployments
  • Comfortable working in a fast-moving startup environment
  • Good communication skills and strong ownership mentality
  • Proficiency in English

Nice to Have

  • Experience with audio processing, ASR, TTS, or voice AI systems
  • Familiarity with WebRTC internals
  • Experience with cloud infrastructure (AWS, GCP, Docker, Kubernetes)
  • Prior experience building scalable real-time products

Benefits

  • Work on core voice & AI infrastructure, not side features
  • High ownership and direct impact
  • Competitive compensation
  • Flexible work culture (outcome-focused)
