• A Full-Stack Specialist - You are equally comfortable navigating a PostgreSQL query, styling a React component, or building a robust controller in Rails.

• A Quality Advocate - You believe “done” includes comprehensive automated tests and clear documentation. You take pride in leaving the codebase better than you found it.

• A Collaborative Problem-Solver - You thrive in an environment where code reviews are a dialogue and cross-functional collaboration is the norm.

• Participate in production support during working hours, addressing bugs and escalations as needed

• Use monitoring and observability tools to maintain application stability and support performance tuning

• Participate in peer code reviews and provide constructive feedback

• Produce technical documentation, including architecture notes, implementation guides, and runbooks

You Should Have
