Software Developer (Ruby On Rails/React)

About Scrumconnect Consulting

Scrumconnect Consulting is a multi‑award‑winning digital consultancy whose work has positively influenced the lives of over 40 million UK citizens. We deliver impactful technology solutions across UK government departments, working at the forefront of user‑centred design, agile delivery, and scalable digital services that genuinely make a difference.

Why This Opportunity Stands Out

• Work on a high‑impact UK public sector digital programme, delivering services used by millions
• Opportunity to be based in Swansea, with relocation support of up to £5,000
• Visa sponsorship available for eligible candidates
• Strong focus on work‑life balance with a flexible hybrid model (3 days onsite)
• Be part of a collaborative, multidisciplinary agile environment alongside civil servants and industry experts

Based in Swansea, South Wales – three days per week on‑site. The role requires three days per week at our client’s Swansea offices. Swansea is a coastal city offering a genuinely excellent quality of life: lower cost of living than London or Birmingham, shorter commutes, and the kind of work‑life balance that is hard to find elsewhere. If you have spent years commuting into a major city, working three days a week by the sea without taking a pay cut may be more appealing than you expect. The work is meaningful too, public sector digital delivery that directly impacts people’s lives across the UK. We also offer relocation support of £3,000‑£5,000 to help make the move straightforward.

The Role

Sr Software Developer will be a core member of a blended digital delivery squad, embedded within the organisation’s major digital delivery programme. You will bridge user needs and technical delivery, designing, building, and supporting high‑volume digital services at pace. Operating across a portfolio of customer‑facing and staff‑facing digital services, you will focus heavily on building accessible, user‑centric interfaces and robust back‑end systems using Ruby on Rails and React. You are comfortable working across all phases of the agile life cycle from pre‑discovery through to live operations.

Key Responsibilities

• Design, build, and support full‑stack digital services using Ruby on Rails and React, ensuring code is scalable, resilient, and accessible.
• Deliver user‑centred, secure‑by‑design services that align closely with the Government Service Standard, Technology Code of Practice, and internal engineering principles.
• Work collaboratively within blended multidisciplinary agile squads, partnering with Product Owners, Agile Delivery Managers, Business Analysts, and Architects to deliver outcomes at pace.
• Integrate APIs and support the decomposition of legacy interfaces to modernise platforms while maintaining service continuity and data integrity.
• Enhance Continuous Integration and Continuous Deployment (CI/CD) pipelines, implementing automated testing (TDD/BDD) to improve deployment frequency, quality, and reliability.
• Embed service reliability through active participation in observability, monitoring, alerting, and proactive incident management.
• Facilitate knowledge transfer, document technical decisions, and coach colleagues to uplift overall team capability and support sustainable service ownership.

Essential Skills & Experience

• Strong commercial experience as a full‑stack or back‑end software developer, primarily utilising Ruby on Rails within high‑volume digital environments.
• Proven proficiency in building accessible, component‑based user interfaces with React.js, HTML5, and CSS3.
• Demonstrable track record of delivering secure, scalable digital services within large‑scale public sector or complex enterprise organisations.
• Deep practical understanding of the GDS Service Standard, the Technology Code of Practice, and secure‑by‑design principles.
• Extensive experience operating in Agile delivery environments (Scrum/Kanban) and working seamlessly within blended client‑supplier teams.
• Strong expertise in automated testing methodologies, including TDD/BDD, unit, integration, and contract testing.
• Familiarity with DevOps culture, including Git version control, Docker, and CI/CD pipeline automation.
• Eligibility for Baseline Personnel Security Standard (BPSS) clearance, with the readiness and eligibility to obtain Security Check (SC) clearance for production access.

Desirable Skills & Experience

• Experience contributing to digital services that have successfully passed GDS (or equivalent) service assessments at Alpha, Private Beta, and Public Beta phases.
• While the primary focus is Ruby on Rails/React, an awareness of or willingness to engage with other core stack technologies (such as Java Spring Boot microservices or AWS Serverless using Lambda/Node.js) is highly advantageous.
• Previous experience integrating cross‑government platforms such as GOV.UK One Login, GOV.UK Notify, or GOV.UK Pay.
• Familiarity with legacy system modernisation and safe migration pathways.

Technical Skills

• Languages & Frameworks: Ruby on Rails, React.js, JavaScript, HTML5, CSS3
• Databases: PostgreSQL, MySQL, or similar relational database systems
• Testing: TDD/BDD, unit/integration testing frameworks (e.g., RSpec, Jest, Mocha)
• Tooling & DevOps: Git, Docker, CI/CD pipelines (Jenkins, GitHub Actions), Infrastructure as Code concepts
• Architecture: API‑first design, RESTful APIs, event‑driven patterns

Working Context & Environment

The organisation is one of the UK government’s largest digital operators, handling millions of customer transactions annually, the vast majority of which are processed digitally. The successful candidate will be embedded in a blended squad of civil servants and supplier staff, working in a scaled agile environment. The wider approved technology stack includes Java SpringBoot for back‑end services, AWS Serverless (Lambda/Node.js), and legacy systems alongside Ruby on Rails and React. As initiatives span a broad portfolio of transformation‑including the integration of cross‑government identity and payment platforms-collaboration and adaptability are essential. A regular on‑site presence at the principal office is required (approximately 60% of the working week) to promote transparent communication and collaborative decision‑making.
