Having invested in and developed their technology for more than a decade, they're now looking for a hands-on Ruby on Rails Tech Lead to become a key technical figure within the business, working closely with the MD as their technical right-hand person.

This is an opportunity to take considerably more ownership than a traditional Senior Engineering position while staying firmly hands-on. You'll work directly alongside the MD, have genuine influence over how products are built and scaled, and gain exposure to the wider commercial journey as established technology moves into its next stage of growth. There's also significant longer-term opportunity. As the UK Engineering function grows, there will be scope for a team to be built around and underneath this position for someone interested in developing their leadership responsibilities. If you're a strong Ruby on Rails Engineer looking for technical ownership, commercial exposure and the opportunity to play an influential role in scaling products and an Engineering function, I'd be keen to speak with you.
