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 are 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 will 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 will 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 have 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
