London, Hybrid – 2–3 days in office and six-figur salary

Skypath is proud to be partnering with a fast-growing technology company that’s building the leading AI-powered platform for the Corporate Travel industry. Their software helps some of the world’s most recognisable enterprises reduce risk, cut costs, protect revenue, and manage emissions in line with business and sustainability goals.

You’re a builder at heart—curious, pragmatic, and motivated to solve complex, meaningful technical challenges. You thrive in early-stage environments where speed, ownership, and adaptability are key. You take initiative, shape outcomes, and enjoy seeing the direct impact of your work.

You’re comfortable working across the full stack, from designing intuitive user experiences to architecting resilient back-end systems. You’re eager to learn new technologies, driven by a passion for leveraging software and data to make a tangible difference in decarbonization and enterprise transformation.

We’re seeking a Senior Software Engineer to join this company’s founding engineering team. This is a rare opportunity to have a direct influence on both the product vision and engineering culture from an early stage.

You’ll build core product features, shape technical architecture, and take ownership of systems from design through deployment. Working closely with product and design, you’ll experiment, iterate quickly, and help define best practices that will scale with the business.

You’ll be based in London, with 2–3 days per week in the office, collaborating directly with leaders on key technical and strategic decisions as the company grows.
