Headquartered in Seattle with an office in San Francisco, we raised $60M Series B in April 2025 led by Sapphire Ventures with Mayfield and Thomson Reuters Ventures, bringing total funding to $91M. We're scaling rapidly and looking for exceptional talent to join us in this next phase of growth.

We're looking for passionate team members who are motivated by our mission and ready to help us achieve it.

Who we're looking for

We're building voice AI agents that handle legal intake calls, helping firms capture critical details from people who need help in the moments that matter most.

You'll own our entire voice stack end-to-end: agents that sound natural, handle messy real conversations, stay on-script when they need to, and recover gracefully when things go sideways. Over time, you’ll develop agents that automatically perform tasks for intake teams and set Supio's overall voice strategy.

We're looking for someone who has shipped production voice agents that people actually use on live phone calls. This is a build-it-and-own-it role. If you've shipped voice agents that work in the wild and want to own the entire voice experience at a growing company, let's talk.

What you'll do

Build and own Supio's voice AI system end-to-end, and design our voice strategy for the future
Design conversation flows for legal intake scenarios such as gathering case details, qualifying leads, scheduling
Make our agents sound human with natural pacing, appropriate interruptions, and empathetic responses
Implement guardrails so agents stay compliant and on-brand even when callers get creative
Handle real-world voice problems: accents, background noise, emotional callers, crosstalk
Stay current with state-of-the art voice agent research

Qualifications

Experience: 5+ years of professional software development experience
Education: Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field, or equivalent practical experience
Proven production voice agent experience: You've built and deployed agents that handle real customer calls at scale
Full Stack experience: You have experience shipping software products end-to-end
