For most people, health insurance is something that happens to them: a plan chosen by someone else, with little room to fit their life. Thatch is changing that. We help companies give every employee a real healthcare budget instead of a one-size-fits-all plan, so people can choose the coverage and care that works for them, and employers get predictable costs they can control.
It’s a simple idea, but making it real means solving hard problems across healthcare, payments, and technology, and we’re just getting started. We look for people who like solving complex problems, use good judgment, and are comfortable working through ambiguity. People here care deeply about our customers, take real responsibility for what gets built, and are driven by doing work that matters.
Thatch is reimagining how health benefits work. We help employers give their employees a healthcare budget to choose the coverage that works best for them, while making benefits easier to manage and costs more predictable for businesses.
We're looking for a Partner Engineer to own the reliability and success of our payroll and HRIS integrations as we scale. You'll work directly with customers, integration partners, and internal teams to solve complex technical challenges, validate new integrations, and keep critical connections running reliably.

- Experience owning complex technical problems across multiple systems, stakeholders, or external partners.
- Confidence working directly with customers, translating technical complexity into clear guidance and solutions.
- Strong ownership mindset, with the ability to independently prioritize issues and drive them through resolution.
- Experience building repeatable processes, documentation, or monitoring practices to improve operational reliability.
- Experience with payroll, HRIS, or benefits platforms, particularly complex enterprise configurations and integrations.
- Experience working with third-party APIs and integration partners, such as Finch, Merge, or similar platforms.
- Experience building internal tools, scripts, or automations to improve integration reliability and reduce manual work.
- Experience in a forward-deployed engineering or technical solutions role, solving complex customer problems and translating them into scalable technical solutions.
We aim to move quickly, and most candidates complete the process within 2–3 weeks. You can expect:
- An initial conversation with a recruiter.
- A conversation with the hiring manager to discuss your experience and approach to technical problem-solving.
