In the last 10 years, Mambu has been revolutionising banking - making it more accessible, more straightforward and more inclusive for everyone. With fresh funding secured and a near €5 billion valuation we have huge ambitions for ourselves and the whole banking sector.

We bring this same sense of innovation and aspiration to how we support our people. We pioneered the 4 day summer work week, have announced the provision of equity for all and launched Our Mambu Deal to capture how we work with each other and what we offer all Mambuvians.

These are just the beginning. We’ll continue to look for ways to make Mambu an even better place to work.

We’re not here to play it safe.

We’re here to change the world.

  • Establish yourself as influencer and technical authority, coaching engineers on architectural thinking and advanced engineering practices, representing Mambu at technical events and conferences and providing proactive technical leadership.

Your future

We’re also focused on delivering a fantastic working experience for all Mambuvians.
