CTO / Founding Full Stack Engineer | Node + React (Equity Only)

Remote, USA Full-time Posted 2026-06-06

Founding Full Stack Developer + Project Manager – WellVantage Please note this is an equity-only position for the first two months! We need people who think about this product as their own and are completely committed. The products are live, and we are getting good traction already! Check our website for app store links: https://wellvantage.ai/ WellVantage is building an AI-powered wellness platform combining gym management and personalised nutrition tracking through two connected apps — one for gyms, one for their members. What you’ll do: As a founding engineer, you will be responsible for delivering some application modules end-to-end. This includes hands-on backend development (NodeJS) and frontend development (React/React Native). The initial development phase is expected to take approximately 2–3 months, and given the startup environment and your ownership of product delivery, this may require working extended hours during this period to ensure a timely and successful launch. Compensation—whether in the form of salary or profit share—will be milestone-based. Upon successful delivery, the role may transition to a full-time fixed salary arrangement.

  • Build and maintain scalable backend APIs (NodeJS)
  • Develop intuitive frontends (React/React Native)
  • Integrate APIs (OpenAI, Firebase, Google Cloud, payment gateways)
  • Ensure secure data handling (GDPR-compliant) and app performance

What we’re looking for:

  • 5+ years of full-time, post-college experience with NodeJS + ReactJS + React Native (not internships)
  • Built and launched 2+ production apps (App Store / Play Store) using NodeJS backend and React/React Native frontend
  • Led full app lifecycle from architecture to launch as Tech Lead or primary dev
  • Strong with JavaScript, REST APIs, MySQL, and Firebase
  • Integrated third-party APIs in production (e.g., Stripe, Razorpay, OpenAI)
  • Open to milestone-based pay/equity and extended hours for the first 2–3 months
  • Willing to complete a 2–3 day evaluation task
