Aspect Health is building an AI co-pilot for lifestyle-driven chronic conditions. They began by addressing women’s metabolic health - starting with PCOS, a condition affecting nearly 20% of women worldwide and a leading cause of female infertility.

In the last 8 months, they’ve grown 1000% - scaling their ARR from $250K to $2.5M - and kicked off our B2B expansion by partnering with six clinics.

Your role

We’re seeking a skilled Full-Stack Engineer to help scale our platform for millions of users managing metabolic health conditions, including PCOS, diabetes, and IBS. This is an ideal role for a Senior engineer who wants to stay deeply involved in code.

You will be the owner of the success of product features - you’ll work with the product counterparts to ensure that the requirements are clear, and then follow up with owning the feature delivery end-to-end.

About You

  • 3+ years of full-stack or backend engineering experience, with expertise in Node.js, TypeScript, and PostgreSQL.
  • Solid command of frontend and mobile development, including React and the Expo framework—able to build and ship features across the full stack.
  • Ability to write production code, review pull requests, and build rapid prototypes for testing ideas or validating demand.
  • Comfortable managing both local and remote engineers, with excellent communication and leadership skills.
  • Knowledge of DevOps and cloud infrastructure, including GCP, Redis, CI/CD (GitLab preferred), and monitoring (Grafana).
  • Proven experience with complete ownership of feature delivery, including experience leading agile processes (standups, retros, sprint planning) and ensuring predictable, on time, on scope delivery.
  • Hands-on experience setting up test frameworks and building test coverage from 0 to 1.
  • Proficiency with analytics and instrumentation tools, including Amplitude, GA4, and basic data debugging.
  • Very good communication skills in English, both written and in person - be able to explain a problem or challenge to a stakeholder over a call, or through slack - and ensure that you have a resolution.

Would Be a Plus

  • Hands-on experience with React Native.
  • Experience with healthcare, wearables, or chronic condition platforms.
  • Prior experience introducing AI tools for engineering velocity (e.g., Copilot, Cursor, codegen pipelines).
  • Passion for building solutions that help people manage chronic health conditions using real-time data.

What You Will Do

  • You’ll define and own the technical backbone of a fast-growing health-tech company solving critical real-world problems.
  • You’ll stay close to code while influencing architecture, delivery processes, and team culture.
  • You’ll have the opportunity to grow into a Team Lead role as the team scales.
  • Your work will empower people with metabolic disorders like PCOS, diabetes, NAFLD, and IBS to regain control of their health using data from wearables and AI.
  • You’ll shape the next generation of AI-enabled developer workflows, boosting productivity through modern tools and smart automation.

What Do We Offer

  • Generous PTO: Take the time you need to stay fresh and inspired.
  • Competitive Compensation: Salary plus benefits to match your experience and dedication.
  • Fast-Paced Growth: In the last eight months, we’ve grown 1000%—scaling our ARR from $250K to $2.5M
  • Impactful Work: Every feature you ship has the potential to improve someone’s quality of life.
  • Collaborative Culture: Work cross-functionally with product, design, and business teams who are all rowing in the same direction.
