Thatch is building software to give employees real control over their health benefits. We're hiring a Backend Software Engineer to design and build core systems powering the platform, including data models, fund flows, automations, and integrations that make healthcare benefits work reliably at scale.
In this role, you'll design, build, and evolve backend systems supporting enrollments, payments, payroll, and benefits management. You'll architect robust data models and fund flows handling large volumes of financial transactions, build integrations with payroll providers, banks, insurance carriers, and external partners, and improve operational rigor through automation, tooling, monitoring, and observability. You'll partner closely with product, operations, and other engineers to solve complex business problems and take ownership of production systems including reliability, debugging, and long-term maintainability.
We're looking for engineers with experience building and maintaining backend systems in production environments and a track record of shipping systems with complex business and operational implications. You should have strong ability to reason about data models, workflows, and edge cases, comfort operating in ambiguous problem spaces with cross-functional tradeoffs, and ideally experience mentoring other engineers or setting technical direction.
Our tech stack includes Ruby on Rails for backend systems, React and TailwindCSS for frontend, and Python/JavaScript where appropriate. Prior Ruby experience is helpful but not required—we value engineers who learn quickly and think clearly about systems.
Experience that stands out includes work in healthcare, finance, or other complex regulated domains; experience with HR, payroll, payments, or partner-facing systems; and ownership of systems with real operational or financial impact. We move quickly, ship early, learn from real usage, and iterate. We operate with trust, ownership, and high empathy, valuing clarity over ceremony and quality over shortcuts.
