About Aspect Health
Aspect Health is building an AI co-pilot for lifestyle-driven chronic conditions. We 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. From here, we’re expanding to tackle IBS and other lifestyle-driven chronic issues, leveraging continuous glucose monitors and advanced at-home tests to deliver real-time, personalized feedback that empowers lasting health changes.
In the last eight months, we’ve grown 1000% 😲 —scaling our ARR from $250K to $2.5M—and kicked off our B2B expansion by partnering with six clinics. We are backed by notable investors, including a16z, Sequoia, Long Journey Ventures, Lux, Valor, and the founders of Flo Health and Deel, among others.
If you’re passionate about transforming healthcare through cutting-edge technology and real-world impact, Aspect Health is the place to be.

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.
Bonus
Experience with healthcare, wearables, or chronic condition platforms.
Prior experience introducing AI tools for engineering velocity (e.g., Copilot, Cursor, codegen pipelines).
Strong product instincts or prior experience collaborating closely with high-performing product managers—able to ask the right questions, challenge assumptions, and think critically about tradeoffs.
Track record of growing into leadership roles in early-stage companies.
Passion for building solutions that help people manage chronic health conditions using real-time data.
Why This Role Is Exciting
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—this is a foundational hire.
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.
