A UK-based boutique travel operator that builds and maintains digital products for holiday bookings and customer experiences. They focus on delivering well-crafted, customer-first web services that support long-term product stability and steady feature evolution. The team values collaboration, pragmatic engineering, and incremental improvement.

We’re hiring a Full Stack Developer with a strong backend focus to join an agile product team. You’ll own APIs and integrations that power customer-facing web applications and work closely with frontend engineers to deliver reliable, maintainable systems.

• Build and maintain APIs (REST and SOAP) using C# / .NET Core
• Integrate with third-party systems (payment gateways, CRMs, analytics)
• Support a planned migration between CMS platforms and other platform upgrades (e.g., modern API patterns, real-time endpoints)
• Write clean, testable code using TDD practices (xUnit/NUnit/MSTest)
• Manage and optimise data access using SQL Server and NoSQL stores
• Collaborate with Vue.js frontend developers to connect APIs to UI components
• Participate in Agile rituals: daily standups, sprint planning, retrospectives
• Use Git and standard engineering tools for CI/CD, issue tracking, and documentation
• Propose improvements for architecture, performance, and scalability

Required

• 3+ years working with C# and .NET Core
• Experience designing and consuming RESTful and SOAP APIs
• Strong SQL skills; working knowledge of NoSQL concepts
• Familiarity with frontend basics: JavaScript, HTML, CSS, and Vue.js
• Comfortable working in Agile/Scrum teams and communicating cross-functionally
• Experience with Git and tools like Azure DevOps, Jira, Confluence (or equivalents)

Optional / nice to have

• Experience working with CMS platforms and migrations
• Understanding of web performance and analytics (Core Web Vitals, Google Analytics)
• Exposure to GraphQL, SignalR, Blazor, or similar modern additions
• Cloud experience (AWS or Azure)
• Familiarity with AI-assisted development tools (GitHub Copilot, etc.)
• Automated testing beyond unit tests (integration testing, end-to-end)

What this team really needs:

• Takes ownership and follows work through to completion
• Clear, concise communicator who can translate technical trade-offs for non-technical stakeholders
• Pragmatic problem-solver who balances quality with shipping value
• Collaborative mindset: pairs well with frontend, product, and QA colleagues
• Curious and coachable — willing to learn new platforms and adapt practices
• Detail-oriented with a focus on reliability and performance
