Job description

Job Title: Fullstack Developer
Job Type: Permanent
Location: Remote UK or Ireland
Salary: £40,000-£75,000 DOE
Skills: C#, .NET, React, TypeScript, SQL Server, Azure (Service Bus, Storage), Signal R, AI
Roc Search have partnered with an Ed Tech SaaS company who are looking for a fullstack .NET/React Software Engineer. They are looking to enhance their development team in support of its strong growth agenda.
They build and operate an eAssessment platform used by clients. They are expanding their existing service and moving into new markets. They have a small and well established development team who are experienced and pragmatic; they care about providing working software, not rebuilding from scratch every time a new framework wins a popularity contest.
This is a role for a full-stack developer to join the core team - someone who can supplement and enhance what they do, and plan to do, and help grow the business.

What you'll be working on

• A mature developed platform covering exam authoring, scheduling, delivery, and results processing.
• Working across the full stack, C# / .NET on the backend, React on the frontend, on features that real organisations depend on.
• Contribute to ongoing UI modernisation project, currently moving to a new React-based interface.

The Role - pre-requisites

• 2-5 years of commercial software development experience
• Solid C# and .NET skills, you don't need to know every framework, but you should understand the language properly
• Comfortable with React and modern JavaScript/TypeScript, with a genuine interest in building good UI
• Experience working directly on user-facing interfaces - not just wiring up components, but thinking about how they actually work for users
• Able to read and write sensible SQL (SQL Server)
• Someone who solves problems with the simplest thing that works, not the most interesting thing that could work.
• Good communication, the team is small and we rely on people saying what they think

The Role - advantages

• Experience with Azure (Service Bus, Blob Storage)
• Familiarity with SignalR or real-time web patterns
• Any background in education technology or assessment
• We use AI coding tools as a normal part of the development workflow
• Familiarity with tools like GitHub Copilot or Claude Code is a plus, though not essential
