You'll be working in a collaborative, engineering-driven team, contributing to a platform that places strong emphasis on performance, security, and real-world impact.

Key Responsibilities

  • Lead and deliver a Ruby on Rails upgrade across an existing production system
  • Identify risks, dependencies, and improvements as part of the upgrade process
  • Design and build robust RESTful APIs to support internal and external integrations
  • Contribute to integration work with third-party systems and internal services
  • Write clean, maintainable, and well-tested code
  • Collaborate with engineers, product teams, and stakeholders to deliver high-quality solutions
  • Support performance optimisation and scalability improvements

Essential

  • Strong commercial experience with Ruby on Rails
  • Proven experience upgrading Rails applications (ideally across multiple versions)
  • Solid understanding of REST APIs and service-based architectures
  • Experience working on production-grade, scalable applications
  • Experience with modern development practices (CI/CD, version control, code reviews)

Desirable

  • Experience with system integrations (third-party APIs, event-driven architectures, etc.)
  • Exposure to cloud environments (AWS, GCP, or similar)
  • Experience working in security-focused or high-availability environments
  • Frontend exposure (React or similar)

The Details

  • Contract: 3 months initially + 3 month extension on a new SoW.
  • IR35: Outside IR35
  • Rate: £500-£550 per day
  • Location: Remote

If you're a Rails specialist who enjoys modernising systems and working on impactful platforms, this is a great opportunity to get involved in a high-quality engineering environment.
