Descrição da oferta de emprego

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.

This is a full-time, permanent position based in our Lisbon office, requiring four days a week onsite.

A Cloud Security Engineer is a contributor to the larger Security Engineering team. We desire engineers who are able to think creatively engineer, design, and build solutions to security problems. We have a passion for exploration of unique solutions and sharing of unique perspectives that you can bring to the team and its work.

The Security Engineering team is cross-functional and made up of diverse people who bring their own unique expertise in either (or both) application security and infrastructure (cloud) security. We allow team members to move from project to project, subject to subject based on their skills, experience, and interests. Each team member brings their own expertise to bear in ways that are collaborative and designed to find the best solutions to complex problems.

The team covers the following areas, and individuals contribute to any of them based on their own expertise:

• Designs and reviews to build a secure product and platform
• Threat modelling to identify relevant areas of focus
• Define the best in class protective and detective security controls
• Development of security tooling and automation
• Implement and maintain cutting-edge tools and measures

A large part of the Thought Machine security function is greenfield; we are building the bank of tomorrow with cutting edge technology. To achieve this we need innovative thinking to create security solutions in 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 to security that lead the industry.

DUTIES

• Provide security expertise and mentorship to Thought Machine engineering teams through the stages of planning, design, and testing of new solutions.
• Co‑develop threat models with engineering teams that identify relevant threats and relevant strategies for mitigation
• Design and build cloud native preventative and detective controls that operate at scale
• Build and maintain automation to actively audit and assess infrastructure‑as‑code and in‑place infrastructure
• Develop (in code) security tooling, contribute to third‑party security products, and develop updates for existing tooling that is in use in our environment
• Work with cloud engineering and operations teams to develop tooling that maintains our secure operating state in production
• Perform security reviews and security testing
• Contribute to the overall security strategy, security tooling selection and creation
• Operate collaboratively with other Thought Machine teams with trust and influence
