Job description

Thought Machine's mission is bold – to properly and permanently rid the world's banks of legacy technology. To achieve this, we have developed the foundations of modern banking through core and payments technology which run natively in the cloud. What we are attempting is hard and means we need great people working together to build great technology.

We have grown rapidly in the past few years – growing our team to more than 550 individuals across offices in London, New York, Singapore, Sydney and our newly established Engineering Hub in Lisbon. We have raised more than £500m in funding and our investors include Molten Ventures, Eurazeo, Intesa Sanpaolo, Temasek, Nyca Partners, JPMorgan Chase Strategic Investments, Standard Chartered Ventures, and more.

We have created a culture that enables our team to produce the best work in the industry while ensuring we have fun along the way. We're regularly cited as having a fantastic workplace culture and have been recognised by Sifted magazine as having one of the highest Glassdoor ratings for a UK fintech company and the industry's most generous employee share package. Named one of the world's most innovative fintechs by Global Finance Magazine, we were also recognised by the Financial Times as one of Europe's fastest-growing companies for two consecutive years—and a UK Best Employer for 2026.

Engineering Managers at Thought Machine lead complex technical projects to deliver on our product roadmap. To accomplish this you will manage a group of talented engineers as they identify issues and implement creative solutions to address them. You will manage your own project deliverables, contribute to the team strategy, and help develop and grow your team. We are particularly excited to hear from people who show strong product ownership and enjoy switching between engineering management and being hands on with technical work.

The security team is cross-functional and comprises diverse people who bring their unique engineering expertise. The team covers the following areas:

• Define the best in class solutions to engineering problems
• Designs to build secure services and platforms
• Engineer unique solutions and tooling to engineering problems
• Implement and maintain cutting-edge solutions and capabilities

A large part of the Thought Machine function is greenfield; we are building the bank of tomorrow with cutting-edge technology. To achieve this, we need innovative thinking to create solutions that fit into our products and our infrastructure. We look for people who think outside the box and outside of traditional silos to find unique solutions and approaches that lead the industry.

Duties

• Working with your team closely on defining and delivering our security engineering roadmap.
• Actively participate in technical discussions and design reviews.
• Measuring your team’s impact.
• Contributing to product strategy.
• Contributing to engineering-wide initiatives as part of the engineering management team on anything from recruitment to team processes.
• Operate collaboratively with other Thought Machine teams with trust and influence
• Develop engineers in your team and help them in their career development.
• Leading by example: Code reviews and hands-on technical work
