The Opportunity

We are looking for a Full Stack Engineer to join our Product & Engineering team. This role will have a strong backend focus, but with the ability to contribute across the stack as needed. You'll work closely with our co-founder, product/design lead, and a tight-knit engineering team to build and maintain our customer-facing products, internal tools, and data platforms.

We are seeking someone who can bring strong database expertise to help strengthen the team's backend capabilities as we continue to scale and evolve our product.

What You'll Do

• Design, build, and maintain backend services, APIs, and databases that power our product.
• Collaborate with our team to deliver full-stack features end-to-end.
• Lead and improve database architecture, performance, and reliability.
• Participate in DevOps and infrastructure projects, including CI/CD, deployments, and monitoring.
• Contribute to architectural decisions as we evolve our stack and scale our systems.
• Work closely with product, design, and leadership to scope and deliver high-impact features.

Qualifications
Required

• Strong backend engineering experience with serverless architectures.
• Solid experience with relational databases (e.g. PostgreSQL, MySQL, RDS) and data modeling.
• Ability to assess and optimize database performance, scaling, and migrations.
• Experience with AWS (Lambdas, EC2, S3, RDS, etc).
• Strong understanding of backend system design and REST API development.
• Familiarity with CI/CD pipelines and infrastructure as code (Terraform, CloudFormation, or similar).
• Comfortable working independently in a fast-paced, remote startup environment.

Preferred

• Frontend experience with React and Vite.
• Backend experience with Node.js.
• Experience with TypeScript.
• Experience with observability, monitoring, and alerting systems.
• Previous experience in healthtech, biotech, or handling sensitive health data.
• Startup or small-team experience where you've worn multiple hats.

How we work

• A mission that actually pulls people in
  We make the microbiome measurable and actionable at every life stage, and real people write in to say it's life-changing.
• Remote-first, real overlap
  Our FTEs are based in North America and work core hours from 9am-6pm CST, shiftable by up to two hours either way - start at 7am or 11am, wrap at 4pm or 8pm.
• Written first, huddle second, meet last
  Default to a clear Slack post, huddle when a thread stalls, and meet only to make a real decision.
• Fast, but never sloppy
  Do the two-month thing in two weeks, then check the work-shipping errors is rework, not speed.
• Shape what we build, not just how we build it
  There's no playbook waiting for you, so write it-and bring the alternative, not just the objection.
• Day One mentality
  Fewer titles and layers; process is a guardrail where it counts, never the reason something didn't ship.
• No hidden agendas
  Numbers, misses, and feedback are shared openly and in real time, so you always know where you stand.
• High standards, genuinely fun people
  Take the work seriously and ourselves much less-high-performing and fun to be around is the hiring bar.
• Is this pace for you?
  Venture-scaled and on a steep trajectory, with intensity in spikes, fiercely protected flexibility, and faster growth than anywhere else.
