Bad Homburg / Frankfurt am Main | Digital Solutions
Backend Engineer (m/w/d)

HQ Trust is one of the oldest and largest independent multi-family offices in Germany. We are managers of highly complex assets owned by private individuals, families and foundations. We are advisors for institutional investors and pension funds. For over 30 years, we have been preserving and growing substantial wealth from generation to generation. We consistently avoid any conflicts of interest.

With HQ Digital Solutions, we create digital solutions to build the digital backbone of our operational business and in the future explore new digital business models and revenue streams. All of our initiatives are driven by our mission to lead the transformation of financial services into the digital future.

As Backend Engineer, you will be working in a team of highly talented technologists to implement new features and maintain the existing infrastructure built on top of React apps (Redux, Material UI, Redux Saga, Cypress, ...) in the frontend and Ruby on Rails API services (JSON API, PostgreSQL, Docker, Kubernetes, ...) in the backend.

Your core responsibility will be building, adapting and extending backend services and database infrastructure in a scalable manner. This will mean to solve technical challenges independently while at the same time you can always rely on your team members to find solutions collaboratively. You should be eager to share your knowledge with your team and at the same time keen to hone your skills.

Apart from the joy of working with modern technologies, we highly value continuous integration & deployments, peer reviews as well as process and test automation.
