Powered by vast data and insights, TTG helps theatres, producers, and cultural institutions reach highly engaged audiences and unlock meaningful revenue, transforming how tickets are sold across the world.

In 2025, TTG entered a new chapter as part of MARI, the global events and experiences company powering world‑defining live experiences. Together, we’re expanding our reach, deepening our impact, and accelerating a shared vision to redefine the event lifecycle through seamless discovery, purchase, and engagement.

We’re looking for a web‑focused engineer to join our Travel Network team, working across LondonTheatre.co.uk and NewYorkTheatreGuide.com—two high‑traffic sites helping tourists and visitors find the perfect theatre show.

What You'll Do:

• Work as part of a product squad focused on driving technical stability and delivering key business outcomes through the continuous refinement of the platform.

• Ensure the platform leverages recent data infrastructure investments to maximise performance and scalability.
• Improve platform observability to proactively monitor performance and reduce downtime.
• Continuously review and optimise platform integrations to meet scaling goals and ensure operational efficiency.
