  • Proactively seek opportunities to reduce scope or streamline development without losing user value

What We're Looking For:

  • Extensive years of backend development experience with production-grade systems

  • Strong expertise in Ruby on Rails, NodeJS, React/TypeScript, REST/GraphQL APIs, Kafka, PostgreSQL

  • Deep understanding of distributed systems, microservices, and serverless patterns

  • Experience mentoring engineers and setting technical directions

  • Ability to make smart trade-offs and simplify complexity without losing quality

  • Background in working with and evolving established backend architectures

  • Pragmatic mindset focused on performance, maintainability, and readability

  • Clear communicator with strong documentation skills

  • Collaborative team player with cross-functional experience

  • Bonus: familiarity with Angular and Golang.
