Thatch is building a healthcare system people actually love. We give companies a smarter, more personal way to offer health benefits and give employees real choice over how they use them.
As a Full Stack Software Engineer, you will own complete product areas from the UI through core models, APIs, and workflows. You will build software that employers rely on to offer benefits in minutes and that employees use to make real healthcare and financial decisions for themselves and their families.
This is a fintech meets healthcare problem. The tools are straightforward. The challenge is designing systems that handle complex business logic, financial correctness, and regulation while still feeling fast and intuitive to users.
We organize engineering around the people we serve members, employers, and partners so teams own end-to-end experiences and ship with speed and accountability.
What you'll do- Own full-stack product areas from concept through production, iteration, and scale.
- Ship user-facing features quickly without sacrificing correctness or long-term maintainability.
- Build across frontend and backend systems that power onboarding, dashboards, payments, and benefits management.
- Translate real user and business needs into clear, pragmatic technical solutions.
- Set and uphold a high bar for code quality, system design, and product polish.
- Take responsibility for production systems, including reliability, debugging, and continuous improvement.
- Experience building and shipping production web applications across the stack.
- Strong product judgment and comfort working through ambiguity.
- Ability to reason about complex systems and business logic.
- Familiarity with modern engineering tools and frameworks.
- A track record of ownership, cross-functional collaboration, and good technical decision-making.
We hire engineers across levels and assess candidates based on scope, impact, and judgment.
Tools and tech stackOur stack is intentionally simple. The hard part is the domain.
- Ruby on Rails for backend systems
- React and TailwindCSS for the frontend
- Small amounts of Python and backend JavaScript where appropriate
Prior Ruby experience is helpful but not required. We care far more about how you think than which language you know.
Experience that stands out- Work in healthcare, finance, or other complex or regulated domains.
- Experience with HR, payroll, payments, or partner-facing systems.
- Ownership of systems with real operational or financial impact.
- We move quickly and bias toward action.
- We ship early, learn from real usage, and iterate.
- We operate with trust, ownership, and high empathy.
- We value clarity over ceremony and quality over shortcuts.
We aim to move quickly, and most candidates complete the process within two weeks. The interview process typically includes:
- A virtual recruiter conversation to discuss your background and interest in Thatch
- A pair programming session focused on collaborative problem solving
- A system design exercise
- A virtual meeting with members of the engineering team
- A final conversation with engineering and company leadership
