Responsibilities:
* Collaborate with cross-functional teams on project requirements and deliverables
* Develop user interfaces using React.JS and Express API's
* Implement database solutions with MongoDB and Node.JS
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
● Work across the stack: databases, APIs, and the plumbing that connects them
● 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
● Push for better tools and approaches as the codebase grows, instead of settling for "it's always been done this way
What you need
● 0-1 years of professional experience building with Ruby on Rails, Java, Python, JavaScript/React, or Node
● Comfortable with JavaScript, HTML, CSS, and jQuery on the front end
● A real grip on data structures and algorithms — not just the interview-prep version
● Solid object-oriented design instincts
● You'd rather write simple, clean code than clever code
● Comfortable with relational databases day-to-day
● Working knowledge of NoSQL is a plus, not a requirement
● Some interest in the math and stats side of finance helps — you don't need to be an expert.
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.
