Neulinx is hiring on behalf of a stealth-mode startup operating at the intersection of healthcare, fintech, and AI. We’re looking for a Founding Fullstack Engineer to help build their core product from scratch. This is the startup’s first technical hire — an opportunity for someone who wants full ownership, fast pace, and real impact.
You’ll work directly with the technical founder (ex-healthtech scaleup) to design, build, and ship the MVP. It’s a hands-on engineering role now, with a clear path to a leadership position as the company grows.
What You’ll Do:
- Architect and build the core platform — backend, frontend, infrastructure
- Own scalability, performance, security, and deployment
- Architecting and scaling LLM-powered applications
- Work side-by-side with product and ops to solve meaningful problems fast
- Shape engineering culture, processes, and future team structure
What We’re Looking For:
- ~4+ years of fullstack development experience, ideally in startups or product-led teams
- ~ Strong backend expertise, especially with Node
- Solid frontend skills — React, TypeScript
- Proven experience building and maintaining production systems
- Bias toward shipping, iterating, and solving problems — not just perfecting code
- Experience in architecting and scaling LLM-powered applications desirable
- Strong communicator who’s comfortable in an unstructured, high-ownership environment
Nice-to-Haves:
- Background in fintech, healthtech, or AI-powered products
- Experience working with LLMs, chat interfaces, or emerging AI tools
Why It’s a Unique Opportunity:
- You’ll own the build — from architecture to first users
- You’ll solve real-world complexity in healthcare and finance
- You’ll have early equity in a venture with long-term growth potential
If you're a fullstack engineer who wants to help launch something meaningful — and own a big piece of the journey — reach out via Neulinx to learn more or apply.
