The posting

The Simulation, Integration, and Test (SIT) department plays a pivotal role in ensuring the successful deployment and operation of satellites by supporting Flight Software, Ground Software, Vehicle Test, and Mission Operations. This is a full stack role with an emphasis on both frontend and backend. Our full stack web applications are operational, user facing products, that needs to be highly reliable. We want someone who wants to be close to their users and iterate with them directly. This role develops and maintains a full-stack application suite that York's test organization runs on. One is our test execution platform and the entry point for all testing across the organization, used by engineers on the production floor to run mission critical tests on real spacecraft before they ship. Another platform is the test artifact management and visualization application for our system of recording test data, capturing results from CI/CD and the production floor and turning them into the dashboards, metrics, and reports that internal teams and customers depend on. The other platform is our full-stack UI/UX for fault injection, simulation control, and visualization of our spacecraft simulation. Together they cover the full arc of a test: run it, see it, and prove what happened. We are looking for an experienced engineer to be a key contributor on these platforms, with the opportunity to grow into broader ownership over time. Responsibilities

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
