About Us
We’re building a platform that helps clinics and digital health startups connect their patients to a wide range of longevity-focused healthcare interventions. The goal is a single Plaid-like integration enabling access to pharmacy, supplements, diagnostics, and more.
We've just raised a Seed round, have a waitlist of customers, and are focused on delivering the initial solution.

- Build our own API for healthtechs and clinics to connect to
- Build a patient-facing checkout page
- A customer dashboard to manage integrations and their patients
- Work most closely with our co-founder / CTO, often in-office in SF
Tech stack:
- React / Nextjs (Typescript)
- Node / Nestjs (Typescript)
- Vercel
- Prisma
- Palumi
- Postgres
- Google Cloud
About You
You MUST have:
- Been a hands-on mid-level, senior, or staff engineer at other early-stage, venture-backed tech startups
- Significant experience building 0 - 1, and understand the engineering and product tradeoffs made in the early days
- Comfortable with our Typescript stack
- Experience designing and building your own APIs from scratch
- Based in the SF / Bay Area only
Nice-to-haves:
- Healthtech experience
- Interest or experience in the product side of product development
- Experience building out infrastructure (AWS/GCP)
- Interest in health, wellness, and longevity (think Huberman, Bryan Johnson, Attia, etc.)
