Job description

CoreReach builds AI voice agents that answer calls for property management companies, day or night. When a resident calls at 2 AM, the agent has to understand them, decide whether it's a real emergency, reach the right person, and leave the team a clear record of what happened.

As an AI Voice Engineer, you'll own how our agents behave on a call: how they listen, what they say, when they escalate, and how we prove they got it right. This is a remote role, open to candidates in the US.

What you'll do

• Design and improve the conversation logic behind our voice agents, from greeting to handoff
• Build the rules that decide what counts as an emergency and who gets called
• Keep the agent's answers accurate and fair-housing safe, with guardrails that hold on every call
• Build evaluation tooling and test suites that catch problems before customers hear them
• Tune prompts, models and settings for faster, more natural conversations
• Monitor call quality in production and debug issues across the voice, telephony and model layers
• Work with product and customer success to turn customer requests into agent behavior

What we're looking for

• 3+ years building software, including production products powered by LLMs
• Strong Python or TypeScript skills
• Hands-on experience with prompt design, evaluation and structured output from LLMs
• Familiarity with speech-to-text and text-to-speech systems
• Good judgment about edge cases, and the habit of testing for them
• Comfort working across the full stack when needed

Nice to have

• Experience with telephony (SIP, WebRTC) or real-time audio
• Experience building evaluation frameworks for generative AI systems
• Voice AI or conversational agents shipped to production
• Background in property management, customer support or call centers

What we offer

• Competitive salary and equity
• Fully remote work with flexible hours
• Health, dental and vision insurance
• Generous PTO and company holidays
• Home office stipend
• Ownership of how our agents behave on every call
