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. If you’re passionate about how technology can supercharge healthcare, you’ll fit right in.

Why we need you

Our small (for now) but mighty 6-person engineering team is tackling big, ambitious problems across Health & Fitness Devices and Lab Testing. We’re already:

  • Streaming timeseries data from 3M+ health and fitness devices 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 are aiming even higher: extracting actionable insights from the tens of billions of data points we ingested every month to help improve patient outcomes:

  • Get excited about shipping features that help detect early signals of chronic diseases and enable early interventions.
  • Are curious enough to build and scale for the data arteries — the millions of device data connections (and growing!) — flowing into the pumping heart that is the Junction Continuous Query system.
  • Obsess over building fault-tolerant backends and clean, well-designed APIs.
  • Ask the right questions to turn rough ideas into reliable production software.
  • Stay pragmatic while navigating domain experts, constraints, and real-world edge cases.

What you’ll be doing day to day

  • Building and scaling our health & fitness device integrations and the Junction Continuous Query system: Designing reliable, well-structured backend services that ingest, process, and serve high-volume medical, health, and wearable data.
  • Improving reliability, performance, and fault tolerance: Work with backend service infrastructure, data pipeline and durable workflows for a wide variety of use cases.
  • Owning full-stack features: Taking rough problems, shaping the approach, and shipping robust backend solutions.
  • 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 → refine with a strong backend engineering mindset.

Requirements

  • Startup engineering experience where you influenced what to build, not just how to build it.
  • Bonus: you’ve built something from 0 → 1.
  • Strong backend engineering experience: Designing and building APIs, working with distributed systems, queues, services, debugging complex production issues.
  • Ability to turn messy or unclear problems into a clear plan.
  • Comfortable working primarily on backend, with some full-stack work when needed.
  • Strong product judgment - within a clear product direction.
  • Fast iteration based on feedback and metrics.
  • Comfortable working in a domain with hard constraints and complex real-world edge cases.

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.
