Senior Developer (ID: j4sgeLJ0)

Senior Software Engineer.  Location: Remote (UK-based) — Occasional travel to the Bristol area (approx. 6–8 times per year)

We’re looking for an experienced Senior Software Engineer to play a key role in the development and evolution of our products. You’ll work closely with a small, highly skilled internal engineering team and collaborate with external development partners where appropriate.

Market leader in enterprise email migration solutions, enabling organisations to move seamlessly between on-premises Exchange Server, Microsoft 365, and third-party archive platforms. Our technology is trusted by a global partner network and our own in-house migration specialists to deliver secure, reliable migrations at scale.

Alongside our core platform, we have launched Version 1 of a new product focused on monitoring GenAI chatbot usage, expanding our product portfolio into emerging technology areas.

You’ll contribute across the full development lifecycle, from design and implementation through to release and support — delivering high-quality software that solves real customer problems. Working alongside the Lead Developer, you’ll help shape technical solutions, improve existing systems, and reduce technical debt that impacts reliability and delivery.

As a senior member of the team, you’ll provide technical leadership through code reviews, pairing, and design discussions, raising engineering standards without formal line-management responsibility. You’ll also make effective use of modern productivity tools, including GenAI-assisted development where appropriate, while ensuring quality, security, and maintainability.
