Job Level

About the role

  • Own features end-to-end from design through production and iteration (API, domain logic, background jobs, and UI).
  • Design and write clean, testable, and maintainable code with clear separation of concerns.
  • Make architectural decisions that improve reliability, scalability, and system clarity.
  • Deliver new features, fix defects, and improve existing systems - not just patch symptoms.
  • Work closely with Developers, Product, Design, and stakeholders to shape solutions, not just implement requirements.
  • Identify risks, edge cases, and tradeoffs early and drive decisions forward.
  • Mentor less experienced engineers on architecture, ownership, and code quality.
  • Contribute to team processes, improving how we deliver, not just what we deliver.

Requirements

  • 5+ years building and maintaining production-grade applications (Ruby on Rails preferred).
  • Proven experience owning features or initiatives end-to-end, not just contributing to tasks.

  • Experience working with relational databases (SQL) and performance considerations (e.g. query efficiency).
  • Familiarity with background processing systems (e.g. Sidekiq, Redis) and async workflows.
  • Experience working with a modern frontend framework (Ember preferred, or strong SPA framework experience).
  • Ability to debug issues across multiple layers (API, database, async jobs, frontend).
  • Strong communication skills and ability to explain technical decisions clearly.
  • Comfortable working in an agile environment with a focus on ownership and delivery.
  • Experience working in cloud environments (AWS preferred) and understanding how applications behave in production.
  • Familiarity with CI/CD pipelines (e.g. GitHub Actions) and safe deployment practices.
  • Understanding of production systems (logging, monitoring, debugging live issues).
  • **Preferred skills: **
  • Experience designing and evolving APIs (REST / JSON-based).
  • Experience refactoring and improving existing/legacy codebases.
  • Experience with Elasticsearch / Searchkick or similar search systems.
  • Familiarity with multi-tenant systems or role-based access patterns.
  • Experience improving system performance, reliability, or developer experience.
