What you will do:
● Design and build features for our web applications — front end and back end, using Ruby on Rails, Python, JavaScript, and React

● Take a feature from first line to shipped — you'll touch every phase of the build, not just one slice of it
● Test for performance, security, and the edge cases that actually break things in production
● Work directly with the rest of the team on shared infrastructure, not off in a corner

Also running in production here — OPTIONAL / NICE TO KNOW You won't be hired against this list. Prior exposure is a genuine plus, and you'll bump into these once you're in — but not knowing them isn't a blocker.
