Senior Software Developer in Grantham, Lincolnshire

£70,000 + benefits

Grantham – hybrid 2 days per week onsite.

If you’re the kind of developer who enjoys building things properly, not just quickly, this could be worth a look! I’m working with a well-funded, growing tech business that’s investing heavily in its product and engineering function. They’ve got a lot going on right now, new features, new ideas, and plenty of scope to shape how things are built rather than just maintaining what’s already there. It’s the sort of environment where good engineers are trusted, listened to, and given the space to do their best work.

The role itself is a hands-on senior position, working across the full stack on a modern TypeScript-based platform. You’ll be helping to build and evolve a conversational, AI-driven product, getting involved in everything from front-end UI work through to backend logic, database design, and deployment.

What’s the Day to Day going to be like:

• Building new features across a Next.js and React platform, including workflow tools and real-time functionality
• Developing API routes and server-side logic
• Designing and working with PostgreSQL databases
• Creating clean, responsive user interfaces using modern component libraries
• Writing and improving unit tests and contributing to overall code quality
• Working closely with product and design to ship features iteratively
• Getting involved in architectural decisions and technical direction

They’re also genuinely embracing AI in the development process, so if you’re already using tools like Copilot or similar (or keen to), you’ll have the chance to push that further here.

What you’ll need to bring:

What they’re looking for is a senior engineer with solid professional experience who’s comfortable across the stack. Strong TypeScript and React/Next.js experience is key, along with a good understanding of how modern web applications are put together, from rendering strategies through to APIs and data layers. You’ll need to be someone who cares about clean code, testing, and building things the right way, but also someone pragmatic who can get things shipped. It’s a collaborative environment, so being able to communicate well and work closely with others matters just as much as technical ability.

Tech-wise, you’ll be working with a stack that includes Next.js, React, TypeScript, PostgreSQL, and AWS, along with modern tooling across testing, CI/CD, and observability. Experience with things like Supabase, Tailwind, or state management libraries would be useful, but not essential.

What they’ll offer in return:

In return, you’ll be joining a business that’s investing properly in both its product and its people. There’s a strong engineering culture, plenty of interesting technical challenges, and real opportunity to influence how things are done. The setup is hybrid, with two days a week in their Grantham office and the rest remote, offering a good balance between collaboration and flexibility.
