Senior Software Engineer (TopEase) Zagreb | Hybrid
F24 is Europe's leading crisis management SaaS platform, trusted by governments, airlines, banks, and Fortune 500s in over 100 countries. Alongside our crisis management technology, F24 also delivers Governance, Risk & Compliance software through our TopEase platform — helping enterprise customers model and manage processes, governance structures, and compliance requirements across complex organisations.
Why F24?
You'll be working on technology that genuinely matters.
TopEase has been in continuous development for over 30 years and is now entering a pivotal phase, with significant investment going into modernising legacy components, improving performance, and unlocking new features ahead of the upcoming TopEase 8.0 release. You'll join a specialised backend team responsible for the core engine that powers every application on the platform — working alongside highly tenured engineers, including architects with decades of domain knowledge, as well as more junior team members.
The work strikes a balance between maintaining a mature, complex system and modernising its architecture and dependencies — tackling technical debt, upgrading Java dependencies, and preparing the platform for future SaaS alignment, all while continuing to ship new features.
