- 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

- Why we need you
- 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 outcome:
- 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
