About the Role
This is a high-impact individual contributor role where you'll own the full product experience — from the APIs that power our platform to the interfaces our members interact with every day. You'll work directly with product and design to ship features that make healthcare more accessible, and you'll use AI tools as a core part of how you build. If you move fast, care deeply about craft, and want your work to matter, this is the role for you.
**MUST BE BASED IN CALIFORNIA**
What You'll Do 
Build and ship full-stack features end-to-end, from backend APIs to polished member-facing UI
Design scalable systems and make deliberate architectural tradeoffs between performance, maintainability, and speed to ship
Integrate AI tools and LLM APIs into product workflows where they add real value
Write clean, well-tested, production-grade code with a high bar for quality
Partner with product, design, and stakeholders across the business to translate requirements into great software
Contribute to engineering standards through code reviews, technical discussion, and better defaults
What You'll Bring 
5+ years of professional software engineering experience with full-stack ownership of production systems
Deep expertise in JavaScript/TypeScript
Strong React and Next.js experience building modern, responsive web applications
Solid fundamentals in system design, testing, debugging, and code review
Habitual, fluent use of AI tools (Claude, Cursor, etc.) as part of your daily workflow
Comfortable owning cloud deployments, preferably on AWS
Bachelor's degree in Computer Science or equivalent practical experience
The Reality
This is a startup. We move fast. We prioritize impact over polish. We expect:
Bias for action — ship, learn, iterate
Ownership — you design it, build it, run it
Pragmatism — solve real problems, not theoretical ones
Resilience — ambiguity comes with the territory
Healthcare is complex and broken. The work matters.
What You'll Get 
Competitive salary, bonus opportunity, and equity package  
Comprehensive Medical, Dental, and Vision benefits
A 401k retirement plan
Paid vacation and company holidays
Opportunity to make an impact at a rapidly growing mission-driven company transforming healthcare in the U.S.
