About Us_
// 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_

// At Masabi, we’re building technology that makes public transport simpler, fairer and more accessible for millions of people. That only works if our platform is secure, trusted and reliable.

As our Head of Security & Compliance, you’ll step into a role that is central to how we build trust with our customers and scale as a global SaaS business.

You’ll own security and compliance end to end, shaping how we approach it as a company and how it works in practice day to day. You’ll lead a small team, bringing clarity, focus and direction as you build on solid foundations and evolve this area alongside the business.

In the near term, you’ll focus on understanding where we are today, strengthening our approach to key areas like audits and compliance, and helping teams move forward with confidence. You’ll work closely with Engineering, Product and Legal to turn requirements into practical, well-executed outcomes.

This is a senior role where you’ll stay close to the work, especially in the early stages. Over time, you’ll shape a more structured and scalable function, helping Masabi stay ahead of evolving standards and make thoughtful decisions around risk.
