Senior Software Engineer

Build the infrastructure of longevity. Work fast. Ship faster. Shape the future of proactive health.

Vitals Vault is building the operating system for human vitality—uniting medical history, real-time biometrics, and predictive AI to transform how people monitor, understand, and extend their healthspan.

We’re looking for a Fullstack Senior Software Engineer—a rare kind of builder who thrives under pressure, ships fast without cutting corners, and wants to define what health looks like for the next decade.

This is an opportunity to build directly alongside the CTO and co-founders in a zero-to-one environment with the velocity, urgency, and intensity of a mission-driven launch team.

Why Vitals Vault?

Mission-Driven Impact

We’re not building another health app. We’re creating a new category: AI-powered longevity optimization. You’ll be part of a team bringing elite-level diagnostics and insights to everyday individuals.

Launch-Mode Intensity

This is not a role for those seeking comfort or routine. We’re building the Minimum Lovable Product (MLP) under intense timelines. Expect long hours, fast pivots, and real ownership. Success brings not just profit sharing, but recognition for building something that will outlast trends.

Exceptional Team

Work with tenured Amazon leaders, ML researchers, and elite designers. You will be surrounded by sharp minds and high standards.

A Purpose Bigger Than Code

You’re not here to polish UI gradients or tweak CRUD apps. You’re here to build the infrastructure of personal longevity, to help people live longer, stronger, and smarter lives.

What you will do:

• Build core features end-to-end across the stack—from APIs and data pipelines to backend services and front-end hooks.
• Work across a backend built in Java, Python, and Node.
• Implement HIPAA-grade security and compliance for sensitive health data.
• Own the technical delivery of complex features (biometric ingestion, diagnostic reports, agentic AI workflows).
• Operate with high urgency—designing, coding, and deploying in days, not weeks.
• Collaborate closely with founders, designers, and data scientists to rapidly iterate based on user feedback.

You might be a fit if you are:

• Are a technical generalist who can dive into any part of the stack and unblock yourself.
• Thrive in high-pressure environments—you’re battle-tested and prefer launch mode over maintenance mode.
• Think in systems, not just in functions.
• Have experience building secure, scalable applications across languages and cloud environments.
• Move with urgency and think like an owner—you don’t wait for permission.
• Can operate in ambiguity, learn fast, and adapt faster.
• Care about performance, quality, and results—but know when done is better than perfect.

Our Current Tech Stack:

Frontend: React Native, Tailwind, TypeScript

Backend: Java, Python, Node.js

AI/LLM: LangChain, agentic orchestration, vector embeddings

Infra: AWS, GCP, Cloudflare, Terraform, Fly.io

Data: HealthLake, Fasten (FHIR APIs), wearable integrations

Process:

• Submit a short intro form (https://n4dcgclj8mj.typeform.com/to/xBzKXokW)
• Quick exploratory call.
• Take-home exercise (brief case + Loom walkthrough).
• Deep-dive technical interviews with founders and engineering team.

We’re not here to build a typical SaaS tool. We’re building something that could change how millions of people think about health, aging, and what’s possible. If you’re ready for a high-stakes challenge and want to build something truly generational—join us.
