Summary Generated by Built In

Sidecar Health is redefining health insurance. Our mission is to make excellent healthcare affordable and accessible for everyone. We know that to accomplish this lofty mission, we need driven people who will make things happen.

The passionate people who make up Sidecar Health’s team come from all over, with backgrounds as tech leaders, policy makers, healthcare professionals, and beyond. And they all have one thing in common—the desire to fix a broken system and make it more personalized, affordable, and transparent.

If you want to use your talents to transform healthcare in the United States, come join us!

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.

Sidecar Health is an Equal Opportunity employer committed to building a diverse team. We do not discriminate on the basis of race, religion, color, national origin, gender, sexual orientation, age, marital status, veteran status or disability status.

Skills Required

  • 5+ years of professional software engineering experience
  • Deep expertise in JavaScript/TypeScript
  • Strong React and Next.js experience
  • Bachelor's degree in Computer Science or equivalent practical experience
