Senior Software Engineer, Full-Stack

Who we're looking for

What you'll build

• The core full-stack application customers work in every day
• 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
• Production 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
• Fluency with coding agents as part of how you build
• Demonstrated experience operating at startup pace and ambiguity — moving fast with less process, owning decisions without a fully-formed spec — at some point in your career
• Autonomy and ownership. Able to meet in-office/hybrid expectations in Seattle or San Francisco

Nice to have

• Hands-on applied AI/LLM systems experience — you've built and shipped real systems and can speak to what you owned and what broke in production
• Prior experience at AI-native companies
• Formal ML background (optional — practical AI fluency matters more than credentials)

• 💰 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
