About the Company

Our client is an early-stage, venture-backed startup building AI voice agents that automate consumer financial-services operations at scale. Their agents already outperform traditional human benchmarks by roughly 2x at a fraction of the cost, and the product has strong, demonstrated traction with real production volume behind it. This is a small, deeply technical team where you'll work directly with the founders.
Founded 2024 · ~8 people · Industry: Financial Services, AI, Fintech

The Role

You'll own the client's voice AI infrastructure end to end — building a voice orchestration framework from the ground up on LiveKit that powers millions of live calls per month in production.

• Design and build an in-house voice orchestration framework on LiveKit from scratch
• Migrate existing AI agents from the current voice provider onto the new system
• Own prompt engineering and conversation design for agents handling millions of consumer interactions
• Optimize real-time voice performance — latency, turn-taking, and state management — at production scale
• Build testing and evaluation frameworks to continuously improve agent quality and business outcomes

Tech stack: Node.js, AWS, SQL, LiveKit, Voice AI, ASR/STT/TTS, LLMs, Python

Requirements

• 3–8 years in backend engineering with hands-on voice AI infrastructure work
• Track record building and shipping production voice AI systems at scale, using LiveKit or a comparable voice framework

• Hands-on experience with a voice AI framework (LiveKit strongly preferred)
• Strong Node.js / JavaScript and AWS skills
• Excellent written communication, which is central to prompt and conversation design
• Based in the NYC area and able to work hybrid, 3+ days per week on-site

• A Big Tech background (e.g. Google, Meta, Roblox) paired with startup or voice AI side projects
• A CS or related technical degree from a strong university
• Prompt engineering and conversational flow design for voice agents

Why Join

• Full ownership of a greenfield voice AI stack running at real production scale
• Meaningful equity and genuine early-stage upside at a fast-growing, venture-backed company
• A tight, senior technical team with direct founder access and no management layers
