Additional details
- 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: use health data to unlock unprecedented insight into human health and disease.
- We’re already connecting millions and scaling fast.
- Short on time? - You: You’re an experienced product builder.
- 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.
- 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. - 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.
- If the problems we’re solving genuinely interest you and you know you can contribute, we’d love to talk.
