Supio is a trusted AI platform purpose-built for law firms, reshaping how data drives impactful outcomes. Our innovative approach blends technology with deep legal expertise, making us a leader in our field. We go beyond surface-level AI to deeply understand our customers’ daily needs, empowering law firms with unparalleled data insights. Supio delivers human-level, accurate analysis of complex data and legal records, quickly and efficiently bringing critical insights when they matter most. Trusted by top litigation lawyers, our platform has supported over $1 billion in settlements.
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.
We're hiring senior, product-minded full-stack engineers to build Supio's agentic platform — applied AI at the core, in high-stakes, real-world legal workflows. You build product end-to-end in TypeScript across the stack, from the interfaces customers touch to the services behind them. You have hands-on experience shipping LLM/AI systems in production, you're fluent using coding agents in your daily workflow, and you operate with real autonomy. You've thrived in a startup environment and you're excited to build greenfield.
(scope depends on team placement)
- Agentic platform capabilities spanning voice calling & transcription, medical/financial records extraction, and legal document drafting
- The agent runtime — prompt/tool architecture, skill and prompt management, and cost/performance optimization
- The core full-stack application customers work in every day
- Production LLM-driven features, plus the evaluation, tooling, and monitoring that keep them accurate and observable at scale
You won't just ship features — you'll shape the architecture and technical direction of a fast-evolving, AI-native platform, with senior autonomy and end-to-end ownership.
- True full-stack depth. You own product end-to-end, front to back. This isn't a front-end or backend specialist role; you're comfortable across the whole stack (React/TypeScript on the front end and modern backend services, APIs, and data pipelines).
- Strong product sense. You build customer-facing product and translate real user needs into technical solutions
- Hands-on applied AI/LLM systems experience. You've built real systems end-to-end and can speak to what you owned and what broke in production
- Fluency with coding agents as part of how you build
- Startup background. Comfortable with ambiguity, speed, and greenfield
- Autonomy and ownership. Able to meet in-office/hybrid expectations in Seattle or San Francisco
- Prior experience at AI-native companies
- Formal ML background (optional — practical AI fluency matters more than credentials)
