Senior Software Engineer, Full-Stack (Agentic Platform)

Location: Seattle Hybrid, San Francisco Hybrid

Department: Software Engineering

Location Type: HYBRID

Employment Type: FULL_TIME

Who we're looking for

What you'll build

• 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

What you'll bring (must-haves)

• 10+ years of professional software engineering experience
• 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)
