Staff Backend Engineer

THE ROLE
Behind every Rythm member experience is a network of systems connecting our product, laboratory, logistics, and operations. As a Staff Backend Engineer, you’ll help build and strengthen that foundation.

You’ll take ownership of complex projects from the first technical decisions through launch and whatever comes next. Since we’re a small team, you’ll work directly with people across the business and have a clear view of how the things you build affect our members and the teams supporting them.

We’re looking for someone who can look at a messy problem, figure out what actually matters, and build a solution that works today without creating headaches down the road. You’ll have a real voice in our backend architecture and engineering practices, but this is still very much a hands-on role. You’ll spend most of your time designing systems, writing code, and improving the platform alongside the rest of the team.

WHAT YOU’LL DO
Design, build, and own reliable backend services and APIs that support Rythm's products and internal operations.
Own complex projects from technical discovery and architecture through implementation, launch and iteration.
Build systems that connect member experiences with laboratory, logistics, billing, analytics, and other operational workflows.
Make architectural decisions that balance delivery speed, maintainability, performance, security, and scale.
Improve service reliability through thoughtful testing, observability, incident response, and operational practices.
Partner with mobile and product engineers to define clear contracts, scalable data flows, and dependable integrations.
Identify technical risks and reduce unnecessary complexity across the platform.
Help establish and evolve development standards and tools as the engineering team continues to grow.
Use modern development tools, including AI-assisted workflows, to increase engineering quality and speed.

WHAT WE’RE LOOKING FOR
Extensive experience designing, building and owning backend systems at scale.
A proven track record of owning complex, cross-functional initiatives.
Experience integrating internal systems and third-party platforms across complex business workflows.
Strong understanding of testing, observability, performance, security, and production operations.
The ability to move between long-term architecture and immediate delivery needs.
Strong communication skills and the ability to work effectively with both technical and nontechnical partners.
A hands-on mindset; you enjoy building and want to remain close to the technical work.
High ownership, low ego, and comfort operating in a fast-moving environment with evolving priorities.
Previous time spent within healthcare, consumer health, or direct to consumer businesses is preferred.
A strong understanding of regulated products and navigating sensitive data is preferred.
