Senior Software Engineer - Ruby on Rails (This client is open to hybrid in Belfast or fully remote UK & EU)

About the opportunity

Enably is hiring on behalf of a high-growth software business looking for a Senior Ruby on Rails Engineer to join its product engineering team.

This is a product-led company with real traction, a strong technical foundation, and a clear focus on building useful software that solves meaningful operational problems for customers. They have grown quickly, built a credible product, and are continuing to invest in engineering as a core part of how they scale.

This is a role for someone who wants to do more than ship tickets. There is real scope here to shape technical direction, influence architecture, and contribute to how the engineering function evolves over time.

Location

This role can be carried out fully remotely, but applicants must be based in either the United Kingdom or the European Union.

Why this role matters

This business wants senior engineers to have room to lead, not just code.

You will join a small, experienced team working across product areas that matter directly to the customer experience and the commercial strength of the platform. You will take ownership of complex work from concept through to production, help guide technical decisions, and play an active part in maintaining a healthy, scalable engineering environment.

This is a hands-on senior role. You will be expected to write high-quality code, think carefully about trade-offs, support others, and help the team move with both pace and care.

What you’ll be doing

• Leading the design and delivery of complex features from concept through to deployment
• Working closely with product and stakeholders to shape scope, challenge assumptions, and deliver practical solutions
• Making sound architectural decisions that keep the application maintainable, scalable, and performant
• Spending meaningful time improving stability, performance, and developer experience, not just feature delivery
• Maintaining a strong automated test suite that supports frequent, confident releases
• Investigating, resolving, and learning from production issues
• Supporting and mentoring other engineers through code reviews, pairing, and shared problem-solving
• Contributing to a pragmatic engineering culture focused on quality, momentum, and long-term sustainability

What they’re looking for

Our client would love to hear from engineers who bring strong Ruby on Rails experience, a thoughtful approach to software design, and the ability to contribute beyond their own output.

You will likely be a strong fit if you have:

• A proven track record designing, building, and scaling production Rails applications
• Strong understanding of Rails fundamentals and how to apply them effectively in real systems
• Experience making architectural decisions that balance speed, quality, and long-term maintainability
• Confidence working across the stack, including frontend technologies such as JavaScript and CSS
• A strong testing mindset and hands-on experience with automated testing
• Experience debugging and resolving complex production issues
• The ability to mentor others and positively influence engineering standards
• Clear communication and good judgment when discussing technical trade-offs
• Comfort using modern AI and LLM-powered tools to support your workflow, while knowing when deep engineering thinking matters more than autocomplete in a fancy suit

Tech stack

This team takes a pragmatic monolith approach and values clean, cohesive engineering over unnecessary complexity.

Core technologies include:

• Ruby on Rails 8
• PostgreSQL
• Redis
• Sidekiq
• TimescaleDB
• Turbo
• React where appropriate for richer UI
• ViewComponents
• Sass
• Minitest
• Capybara
• Playwright
• Stripe
• GitHub Actions
• Heroku

You do not need to have used every tool listed above, but strong Rails depth and sound engineering judgment are important.

What’s on offer

• Competitive salary starting from £75,000 depending on experience
• Fully remote working within the UK or EU
• Belfast office hybrid access for those based locally
• Private health insurance for you and your family
• Company pension
• 35 days annual leave
