Fullstack Engineer

We’re looking for talented Full Stack Developers who enjoy solving complex problems and want to take real ownership of their work. While our core focus is on backend systems, we value engineers who understand the full stack and can contribute across the entire application lifecycle. You’ll be joining a small, highly collaborative team working on systems that support a public sector organisation and several stakeholders. Our environment is dynamic-no two days are the same-so we need developers who thrive on variety, are comfortable navigating ambiguity, and can respond quickly to evolving challenges. This is a role for someone who wants to make decisions, take responsibility, and have a genuine impact on the product, rather than just follow instructions. Why Join Us?

• Real ownership: You’ll have the autonomy to design, build, and deliver solutions-not just implement tickets.
• Challenging work: Our projects are complex and meaningful, giving you opportunities to grow your technical and problem-solving skills.
• Flexible, remote-first culture: Work independently or collaborate closely-whatever gets the best result.
• Freedom with responsibility: We trust our developers to make informed decisions within a supportive team environment.
• Varied day-to-day work: Expect a fast-paced, ever-changing environment where your input genuinely matters.
