Introducing Masabi 

// At Masabi, we’re driving the fare payment revolution, powering the journeys of millions all over the world. We build fare collection platforms that allow riders to seamlessly buy and present tickets for public transport either on their mobile phones, from a ticket machine, or even by tapping their bank card to travel. 

Our Justride platform is used in over 250 locations globally, including some of the largest cities in the world. With our industry-first mobile ticketing SDK, we’ve partnered with large players in the transport space, including Uber, Moovit and Transit. 

Your own journey is important to us too. Choosing a role here means joining a network of innovators from all walks of life; a group of passionate individuals who consistently deliver. Here, you’ll find the tools you need to build the career you want. Whether you’re taking the direct route or trying a new path, we’ll support you no matter what. 

The Role_
// Masabi is hiring a hands-on, deeply technical Chief Technology Officer to shape the next era of our platform’s architecture, innovation, and customer impact.

This role is central to Masabi’s strategic direction, combining architectural ownership, technical excellence, and product foresight to drive global transit transformation. For candidates favouring a traditional CTO role, the scope covers the entire Engineering organisation of about 150 people, including development, operations and compliance. However, we are equally open to candidates with a more hands-on technical profile over people and process management.

This flexibility is supported by a strong Senior Director of Engineering who oversees day-to-day team management and a technical Chief Product Officer who can partner on shared responsibilities.

In either model, you’ll be our most senior and capable technologist, championing architectural clarity, technical depth, and inclusive, AI-driven innovation. You’ll also be a key figure in strategic customer engagements, especially where technology is at the core of the conversation.

Location_
// This is a remote-first leadership role, open to candidates in the UK. Some occasional travel may be required for planning sessions, strategic customer engagement, or team events.
