About the Role

We are looking for an enthusiastic Full Stack .NET Engineer to join our team. You will work in the Researcher Profiles Service team, where we build and manage a global‑scale academic data platform. Through powerful APIs and intuitive UIs, we make critical research information accessible to the rest of the company and to end‑users worldwide.

We have fully embraced AI‑based spec‑driven design, integrating AI throughout the entire software development lifecycle. From specification to implementation, AI tooling shapes how we architect, build, and iterate—making us faster, more deliberate, and focused on what matters most. This is not an experiment;

it is how we work.

You will take ownership of high‑impact projects and drive them to success in a team that is redefining how modern software is built.
