Healthcare is in crisis and the people behind the results deserve better. With data exploding across wearables, lab tests, and patient–doctor interactions, we’re entering an era where data is abundant. Junction is building the infrastructure layer for diagnostic healthcare, making patient data accessible, actionable, and automated across labs and devices. Our mission is simple but ambitious: use health data to unlock unprecedented insight into human health and disease.
If you’re passionate about how technology can supercharge healthcare, you’ll fit right in. Backed by Creandum, Point Nine, 20VC, YC, and leading angels, we’re working to solve one of the biggest challenges of our time: making healthcare personalized, proactive, and affordable. We’re already connecting millions and scaling fast.
You: You’re an experienced product builder. You’re motivated to help predict chronic diseases - faster and more affordably.
Us: Team size 35, 6 engineers, revenue 4x'd in the last year.
Salary: ÂŁ90K - ÂŁ130K + equity (doe + location)
Location: Fully remote (GMT timezone)
Why we need you: Our small (for now) but mighty 6-person engineering team is tackling big, ambitious problems across wearables and lab testing. We’re already:
- Streaming time-series data from 3M+ wearables every second
- Helping major digital health companies deliver 4M+ lab tests across all 50 US states
- Saving millions of patients thousands of dollars
Now we’re aiming even higher: going from 4 million lab tests to 40 million diagnostics in the next year. To get there, we need full-stack engineers who can help us build the next version of our diagnostics API.
You don’t need healthcare experience but you do need to:
- Get excited about shipping features that can cut medical bills by 10x
- Be curious enough to unpack messy insurance incentives and parse thousands of records to estimate true out-of-pocket costs for patients
- Ask sharp questions to take a problem from “rough idea” to shipped software
- Stay pragmatic and comfortable navigating domain experts, constraints, and real-world edge cases
- Care deeply about UX: build interfaces that feel intuitive and clearly communicate complex healthcare information
What you’ll be doing day to day:
- Building our customer facing products: we have dashboards for both product verticals, wearables and lab testing. For example, the lab testing dashboard allows customers to self serve and order lab tests for their patients.
- Speaking with customers: for this role, we need you to be customer obsessed, asking thought-provoking questions and digging into product usage.
- Owning full-stack features: You’ll design and build new functionality end-to-end across frontend and backend.
- Tackling ambitious problems: you’ll be breaking down technical challenges that haven’t been done before in healthcare, we need you to be extremely product minded with every line of code you write.
- Iterating quickly: ship, learn from real usage, and refine to make the experience better each time.
Requirements:
- Startup engineering experience where you influenced what to build, not just how to build it
- Bonus: you’ve built something from 0 → 1
- A track record of building and shipping full-stack features end-to-end
- Ability to turn messy or unclear problems into a clear plan
- Comfortable working across frontend and backend (perfection in both not required)
- Strong product judgment - within a clear product direction
- Focus on how people actually use the product, not just code elegance
- Fast iteration based on feedback and metrics
- Comfortable working in a domain with hard constraints and complex real-world edge cases
- Proactive about getting feedback from customers on what you ship
You don’t need to tick every box to fit in here. If the problems we’re solving genuinely interest you and you know you can contribute, we’d love to talk.

Salary: ÂŁ90K - ÂŁ130K + equity (doe + location). Your salary is dependant on your location and experience level, generated by our salary calculator.
