- Own the operational excellence of your domain, including instrumentation, monitoring and alerting.
- Ensure product quality through thorough automated testing.
- Drive delivery of complex features end-to-end, working across team boundaries when needed.

We value personal and cultural fit as much as technical skill. You are self‑motivated, enjoy collaborating to find the right solution, and think about architecture, development cost, and long‑term ownership when making decisions. You’re comfortable working through ambiguity, can articulate trade‑offs clearly, and leave projects in a state where someone else can pick them up.
Must have:
- Typically 8+ years of professional experience with modern software development practices, though we recognise some people get there faster.
- Strong software design and engineering fundamentals, including object‑oriented analysis and design.
- Solid experience with C# and .NET, and with React on the frontend.
- Hands‑on experience with CMS platforms, content modelling, or digital experience tooling.
- You understand the domain and the problems content teams face.
- Experience building and operating cloud‑based software.
- Already using AI tools, coding assistants, and potentially agents as part of your daily workflow to improve both quality and speed.
- Comfortable working in an agile environment alongside designers, product managers, and other stakeholders.
- Good communicator who enjoys solving problems together with others.
Good to have:
- Experience with Optimizely CMS or other CMS/DXP platforms.
- .NET Core MVC.
- SQL (particularly MS SQL).
- Containers and container orchestration.
- HTTP APIs, REST services, or GraphQL.
- Experience building large, modular applications with continuous delivery.
- A degree in Computer Science or equivalent. We care more about what you can do than what’s on your diploma.
