Python Developer

Lucida AI builds voice-first, AI-powered products used by users across multiple countries. Backed by $6.7M in funding, we focus on real-time speech, AI-driven conversations, and scalable voice infrastructure.

We’re looking for a Python Developer who will work on real-time audio, voice pipelines, and LiveKit-based systems, and help us build reliable, low-latency production systems.

This is a hands-on role with real ownership and direct impact on the core product.

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)
• Top-tier equipment and tools
• Steep learning curve in real-time AI systems
