Senior Software Developer | Webigence and Spark Travel in Hull

About Webigence and Spark Travel. Webigence has 25 years of experience crafting UX‐first, often highly complex software. Our engineers pair forward‐thinking agile practices with an obsession for intuitive design, shipping products that feel effortless even when the logic underneath is anything but.

Alongside a handful of long‐standing third‐party clients, we're scaling our own SaaS product—Spark Travel—at pace. You'll join a smart, collaborative team that pushes each other to articulate and defend every architectural decision in pursuit of best‐in‐class software. Spark Travel itself is on a mission to drag the tailor‐made travel industry into the 21st century. Our cloud‐native platform unifies sales, supplier contracting, dynamic pricing, and on‐trip operations—everything from the first quote to the traveller's safe return.

The market is huge, the incumbents are slow, and we already have meaningful traction: roughly 35 customers and an accelerating sign‐up pace, a very healthy sales pipeline, and a roadmap brimming with genuinely novel features. With a fantastic existing team across engineering, product, customer success, marketing, and sales, we're gearing up for hyper‐growth.

We're looking for two down‐to‐earth professionals, a conscientious Senior Software Developer, to build on what already works and unlock our next wave of innovation.

• Raise the bar sensibly. Whether you're refining our Azure architecture as CTO or shipping revenue‐critical features as Senior Dev, you'll set high standards without reinventing the wheel.
• Champion intuitive user experiences. Both roles care deeply about usability, ensuring our platform feels effortless for travel pros and their travellers.
• Own the craft. Understand the problem, ship the solution, measure the outcome—and when something's working, double‐down on it.
• Move the needle. Your work will streamline the day‐to‐day of leading tailor‐made tour operators and DMCs—enhancing trip experiences for their travellers as we scale.
