Original job description

ABOUT US

Rythm is the fastest-growing lab in America. We redefined at-home testing with the world’s easiest blood test and created a culture around monthly lab testing from home. We’ve processed millions of tests across all 50 states, and we do everything in-house, from sample testing and logistics to code, marketing, and design. That vertical integration gives us the speed, control, and creativity to shape the future of health and wellness.

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.

WHAT’S IN IT FOR YOU?

Rythm Health offers a benefits package which includes:

A highly competitive base salary.
Meaningful equity aligned with the scope and impact of your role.
A monthly Rythm membership with full access to at-home blood testing and personalized health insights.
High ownership and visibility from day one, with the ability to make a meaningful impact.
The chance to help shape the future of personalized health and preventative care.
Flexible, remote-first work environment.
A generous paid time off policy.
401(k).
Multiple healthcare plan options, with select plans fully covered by Rythm.
A small, collaborative, mission-driven team that moves quickly and values great ideas regardless of title.
