Looking for more than just shipping features? This is your chance to work on a modern, growing platform where code quality, scalability, and purpose all matter. We’re working with one of the UK’s most exciting SaaS companies, they’re growing fast, staying humble, and quietly transforming their sector with powerful, thoughtfully built tech.
As a Ruby Developer, you’ll be joining a collaborative, curious, and experienced team, helping to scale a product that solves real-world problems for thousands of users, with a strong emphasis on clean code, maintainability, and smart design decisions.
What You’ll Be Doing
- Writing clean, idiomatic Ruby code (Rails-based) with strong architectural thinking
- Applying solid knowledge of Ruby method lookup, modules (include, prepend, extend), and metaprogramming principles
- Helping design scalable, performant systems that follow composition over inheritance where appropriate
- Supporting design decisions around business logic placement in Rails (models vs. services vs. concerns), including validations, callbacks, and modular structure
- Leading on writing and maintaining unit and integration tests (RSpec) — and knowing the difference
- Contributing to optimisation efforts in both code and database (e.g. indexing, eager loading, partitioning)
- Participating in pair programming, peer reviews, and cross-functional collaboration with product and design
- Helping evolve the system architecture (SOLID principles, microservices where appropriate)
- Getting involved in CI/CD pipelines, infrastructure work (AWS, Docker, Terraform), and occasionally debugging tricky production issues
What You’ll Bring
- Strong commercial experience writing Ruby (Rails) in production environments
- Good understanding of object-oriented design, method lookup, and module usage in Ruby
- Experience with testing strategies, and when to use unit vs integration tests
- Comfortable with CI/CD, Git, and working in a structured, agile product team
- Familiarity with cloud-native tools (AWS preferred) and containerised development
- A keen interest in improving code quality, performance, and maintainability
- Comfortable reading, reasoning about, and writing scalable systems that prioritise readability and clarity over cleverness
Why Join?
- Remote-first setup with flexible working with monthly Manchester meetups
- A calm, curious, and supportive team culture, no egos, no burnout
- A platform that’s growing rapidly, with real users, real complexity, and real business value
- Strong focus on clean code, shared ownership, and continual learning
- Work with engineers who genuinely care about good design, test coverage, and the craft of development
