Security Engineer

Tuum is a next-generation banking platform. We enable fintech and banks to rapidly offer seamless and tailored financial services to their customers. Our core banking platform is revolutionising the financial services industry. The platform is API-based, consisting of flexible and independent modules covering all retail and business banking capabilities for quick and easy integration.

Launched in 2019, Tuum is headquartered in Tallinn and is backed by investors including Citibank, BlackFin Capital Partners, Karma Ventures, Portage Ventures, SpeedInvest, and CommerzVentures.

We're looking for a Security Engineer to help keep that platform safe, along with the money and data our customers trust us with. This role works well whether you're early in your security career or have years of experience — what matters most is how you think. Working directly with the Head of Security, you’ll dig into our cloud infrastructure, CI/CD pipeline, and product code to find weaknesses before attackers do and build guardrails that stop whole classes of bugs. This is a hands-on, build-oriented role: more code, automation, and root-cause fixes than tickets.
