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. What you'll build (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. What you'll bring (must-haves) • 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 Nice to have • Prior experience at AI-native companies • Formal ML background (optional - practical AI fluency matters more than credentials) Compensation Competitive package of base salary, meaningful equity, and benefits. Seattle: $180,000-$255,000 annually San Francisco: $200,000-$255,000 annually Actual comp depends on qualifications, skills, experience, and location. Compensation & Benefits • Competitive Salary + Meaningful Equity • 401(k) • Health, Dental, Vision, and Life Insurance • Flexible Time Off + Holidays • High-autonomy work environment, every Tuesday is a Remote Work Day • DoorDash subsidies for breakfast and dinner; Daily lunch options • Boba Wednesdays • Monthly commuter subsidies and pre-tax parking contribution • Team gatherings and offsites
