Product Engineer

About the role

Healthcare is in crisis and the people behind the results deserve better. With more and more data coming from 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: build the infrastructure that makes predictive, personalized care possible.

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.

Short on time?

- You: You’re an experienced product builder. You’re motivated to help predict chronic diseases - faster and more affordably

- Us: Team size ~60, revenue 4x'd in the last year

- Salary: £90K - £130K + equity

- 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 features across the stack: You'll own features end-to-end across frontend and backend, and in the cloud. You'll build new functionality, design clean APIs, and manage reliable, fault-tolerant services and pipelines in production.
