AI Agent Engineer (voice)

AI Agent Engineer (Voice)

New York, (Hybrid)

Up to $300K + Equity

My client is an early stage Y Combinator-backed AI Voice Agent start up with $7M in funding. They have scaled to ~$2.5M ARR in under 18 months and targeting $10M ARR by end of next year.

• AI agents already outperforming human collectors by 2X at a fraction of the cost — real product-market fit in a $35B US market.
• $200K–$300K salary plus 0.25%–1% equity. Meaningful ownership at a very early stage with massive upside.
• You’d own the entire voice AI infrastructure from scratch — building on LiveKit to power 10 million calls per month in production. Complete autonomy with no layers of management.
• Small team (8 people) means massive impact and direct access to the founder and CTO. Hybrid in NYC with flexibility on in-office days.

We are looking for an AI Agent Engineer with 3-7 years of experience to build our entire voice AI infrastructure in-house on LiveKit. You’ll own the end-to-end development of a voice orchestration framework powering 10 million calls per month for a YC-backed startup that’s scaled to $2.5M ARR and targeting $10M within the next year.

What will you be doing?

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

Requirements:

• 3 - 8 years of experience in voice AI infrastructure and backend engineering
• Built production voice AI systems at scale (e. g. LiveKit, similar voice frameworks)
• Built voice/agentic systems from scratch — ideally as founding engineer or at early- stage startup
• Experience at reputable voice AI companies
• Big Tech (Google, Meta, Roblox) OK if combined with startup or voice AI side projects
• CS degree or related technical field from a strong university
• Voice AI framework experience — LiveKit strongly preferred
• Node. js / JavaScript and AWS proficiency
• Prompt engineering and conversational flow design for voice agents
• Strong written communication — needed for prompt engineering and conversation design work
• Based in NYC — hybrid 3+ days/week in Flatiron office
