At Tandem Health we’re reimagining healthcare by putting clinicians first. Our platform - designed by clinicians, for clinicians -
is built on deep insight into real-world pain points, with intuitive medical notes and workflows that truly support patient care.
We’re a fast-scaling health-tech company backed by top investors and expanding globally. We move fast, stay curious, and believe
building something that matters starts with an extraordinary team. If you're passionate about impact and innovation, we'd love to
meet you!
You love solving problems with technology. At your previous job you were the person who really got stuff done, and because you
understood how everything worked you were someone people often came to for help. At Tandem, those skills will be applied to
problems that really matter - problems that help ensure our healthcare system functions properly. You’ll be designing,
implementing, and debugging high-stakes, complex systems together with other engineers who are deeply engaged and care about both
our mission and the technology we build.
You’ll work across the stack and collaborate closely with multiple teams, contributing to technical decisions, supporting others
through collaboration and knowledge sharing, and helping ensure our systems are performant, reliable, and continuously improving.
This is a high-impact role where you’ll help shape both the product and the way we build it. You’ll be responsible for writing
excellent code, taking ownership of well-defined problem areas, and driving features and improvements from design to production.
If you’re excited about building meaningful products and tackling challenging technical problems in a fast-moving environment,
we’d love to meet you.
