# Staff Backend Engineer,

> Rythm Health · United States (Remote) · Full-time · Posted 2026-10-12

**Workplace:** remote

**Department:** Engineering

## 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.
