  • Engineering-driven culture: We value ownership, autonomy, testing, and thoughtful problem-solving.

  • Growth without chaotic hype: Mentorship and long-term career paths without chaos.

  • Fair compensation + great benefits: Designed to support your well-being both inside and outside of work.

What You’ll Do

  • Own features from implementation to production within a well-defined product scope

  • Build and maintain robust Ruby on Rails systems used at scale

  • Work closely with product and other developers to solve real user problems

  • Write and maintain automated tests (unit, integration, and E2E)

  • Improve performance, reliability, and maintainability of existing systems

  • Take responsibility for the quality and long-term health of what you build

What We’re Looking For

Required

  • 4+ years of professional experience with Ruby on Rails

  • Strong backend engineering skills and database experience

  • Solid experience writing and maintaining automated tests (including E2E)

  • Experience building and running production systems

  • Strong problem-solving mindset, you look beyond tickets

  • Experience with Web APIs

Nice to Have 

  • Experience with React 

  • CI/CD experience (GitLab, Jenkins, or similar)

  • Background jobs, AWS, or complex integrations

  • Experience with Capybara

This Role Is a Great Fit If You:

  • Take pride in ownership and accountability

  • Care about testing and long-term code quality
