About Abound
We’re redefining consumer lending in the UK, and beyond. Using advanced AI and Open Banking data, we make fair, affordable personal finance available to more people. While traditional lenders rely almost entirely on credit scores, we look at the full financial picture - how much you spend, and what you can afford to repay to build a deeper, more accurate understanding of each customer's unique financial situation.
And we've shown it works at scale. We’ve issued over £1.3bn in loans directly to customers while delivering market-leading credit performance - for every 10 defaults the industry expects, we see only 3. We also reached profitability just 2.5 years after launch.
Backed by £2bn+ of funding from top-tier investors including Citi, GSR Ventures, and Deutsche Bank, we’re recognised as one of Europe’s fastest-growing fintechs (Sifted, CNBC). Now, we’re expanding into new markets and product lines - and we’re looking for ambitious people who want to learn fast, take ownership, and grow with us.
About the role:
You won't be sitting in an ivory tower throwing policies over the fence. You will be embedded directly within our Platform team in a true DevSecOps capacity. Operating as a highly technical individual contributor, you will bridge the gap between product-led engineering and Corporate IT.
You will play a hands-on role in challenging the security architecture of production and corporate IT infrastructure.
In your first 6–12 months, you will design and implement our next-generation cloud security architecture across AWS and GCP, while helping to build and mature our internal SOC capabilities, including detection and response.
You will take ownership of Microsoft Sentinel, enhancing our SIEM/SOAR capabilities, and strengthen identity and access management through improved and automated RBAC across AWS, Microsoft Entra, and internal systems.
You will also drive a shift-left approach to security by embedding controls into GitLab CI/CD pipelines, including scanning, IaC reviews, and automated policy enforcement across the SDLC.
