Location: Peterborough or London (Hybrid)
Reporting to: DevOps Manager
We’re looking for a Senior Full‑Stack Developer to join a technology function that’s in the middle of an exciting modernisation journey. This is a hands‑on, senior individual contributor role where you’ll help modernise business‑critical systems, improve engineering standards, and deliver scalable, cloud‑first solutions.
You’ll work across both legacy and modern platforms, taking ownership of complex technical challenges end‑to‑end. This role is ideal for someone who enjoys solving real‑world problems, takes pride in well‑designed systems, and is motivated by improving platforms and practices for the long term.
You’ll have the opportunity to play a key role in modernising critical platforms, influence engineering standards, and work alongside experienced engineers, architects and product teams — all while remaining hands‑on with the technology.
What you’ll be doing:
* Design, build and support full‑stack applications using .NET, React and Azure
* Take ownership of complex deliverables across the full software development lifecycle
* Build and maintain scalable REST APIs, front‑end components, business services and system integrations
* Contribute to microservices design and evolution (and micro‑frontends where appropriate)
* Work on business‑critical workflows involving transactions, validation and data integration
* Incrementally modernise legacy and monolithic systems, reducing technical debt pragmatically
* Ensure solutions align with architecture, security, risk and compliance standards
* Write clean, maintainable, well‑tested and well‑documented code
* Contribute to automated testing, CI/CD pipelines and release processes
* Investigate and resolve live incidents and performance issues, carrying out root‑cause analysis
* Participate actively in code reviews, design discussions and technical decision‑making
* Mentor and support less experienced developers
* Champion good engineering practice across quality, security, resilience and supportability
The technology environment
You’ll be working within a predominantly .NET‑based estate supported by modern cloud and DevOps tooling, including:
* Docker and containerised development
* Orchestrated pipelines embedded into live products
While deep analytics expertise isn’t required, an understanding of how applications integrate with data platforms is important.
We are looking for people with:
* Strong commercial experience building web applications with .NET / .NET Core
* Excellent knowledge of C#, ASP.NET Core, REST APIs, MVC, LINQ and Entity Framework
* Strong front‑end experience with React, including component‑based architecture
* Experience with state management (Redux, Context API or similar)
* Proven experience building and supporting scalable, production‑grade systems
* Strong SQL and relational database experience
* Experience working in cloud‑hosted or hybrid environments (Azure preferred)
* CI/CD pipelines and modern DevOps practices
* Unit testing and automated quality practices
* Agile delivery experience (Scrum, Kanban or similar)
* Comfortable supporting live systems and responding to incidents
* Strong problem‑solving skills and the ability to work in large or unfamiliar codebases
* Clear communication skills and a collaborative, low‑ego mindset
* Experience modernising legacy or monolithic systems
* Experience with workflow‑driven or data‑centric platforms
* Experience in environments requiring high resilience, auditability and data quality
* Experience working with distributed engineering teams
* Degree in a relevant technical discipline
Even if you don’t meet every requirement, we’d still love to hear from you. If you’re excited about the role and believe you could be a great fit, we encourage you to apply.
What’s in it for you:
We offer a comprehensive benefits package to support your wellbeing and lifestyle, including:
* Contributory pension, including life assurance, and income protection
* Informal hybrid working arrangements, combining in‑office and remote/home working.
* Additional leave: 2 paid volunteering days per year and family‑friendly policy
* Wellbeing support, including our Employee Assistance Programme
* On‑site gym and parking at Stuart House, Peterborough
* Reward Gateway scheme – Smart Spending App with access to a range of deals and discounts
* Salary‑sacrifice options including private medical insurance, car scheme, and holiday purchase scheme
* Learning and development opportunities
* Executive coaching and mentoring available to all colleagues
