About the Role

As a Senior Ruby on Rails Engineer, you will play a key role in the ongoing development, enhancement, and stability of a large-scale, production Software-as-a-Service platform. This is a senior, hands-on engineering role where you will take ownership of entire problem domains, contribute across the full software stack, and help move the platform forward in line with long-term product strategy.

You’ll work closely with Engineering and Product teams in a collaborative, agile environment, contributing not only to feature development but also to platform operations, technical quality, and system reliability. The role is primarily remote and requires strong communication skills and a high level of technical ownership.

Responsibilities

• Design, build, and enhance features across the full Ruby on Rails application stack
• Take ownership of defined problem spaces, from solution design through to release
• Refactor and maintain existing SaaS functionality to improve performance, scalability, and maintainability
• Implement robust automated test coverage to ensure solutions meet acceptance criteria and behave as expected
• Conduct code reviews and provide constructive feedback to maintain high engineering standards
• Manage development tasks end-to-end, from backlog refinement to production deployment
• Collaborate with Product and Engineering teams during backlog grooming and issue refinement
• Act as a technical expert within the team, supporting colleagues and resolving development blockers
• Build and maintain a deep understanding of system functionality, data structures, and data sources
• Identify and address technical debt, data quality issues, and user experience inconsistencies
• Contribute to platform operations by maintaining application containers, dependencies, and framework versions
• Deploy to non-production and production environments following established deployment processes
• Monitor application and infrastructure performance, investigating and resolving issues as they arise
• Support the ongoing stability, security, and availability of the platform

Requirements

• 7+ years of professional experience developing with Ruby and Ruby on Rails in production environments
• Strong experience maintaining and operating production Ruby on Rails SaaS applications
• Proficiency with RSpec for automated testing
• Strong JavaScript experience, including native JavaScript and jQuery
• Solid front-end fundamentals: HTML, CSS, and preprocessors such as HAML, SASS, or SCSS
• Experience building and maintaining scalable REST APIs using Ruby on Rails
• Strong understanding of agile development practices and working within cross-functional teams
• Experience using Git and GitHub as part of a collaborative development workflow
• Familiarity with application performance monitoring tools (e.g. AppSignal, New Relic)
• Ability to plan, prioritise, and deliver work across a variable workload
• Strong written and verbal communication skills, essential for a remote-first environment
• Professional, collaborative approach when working across teams and functions

Nice to Have

• Experience with DevOps practices, including infrastructure-as-code tools such as Terraform
• Exposure to cloud-based infrastructure, including deployment, monitoring, and resource provisioning
• Hands-on experience with CI/CD pipelines and automated deployment workflows
• Experience working with containerised applications, including Docker and orchestration concepts
• Familiarity with GitHub Actions for process automation
• PostgreSQL experience, including database administration and Active Record migrations
• Experience with Hotwire-based frameworks, such as Stimulus
• Exposure to ETL data integration processes
• Experience working within Scaled Agile Framework (SAFe) environments
