Application Engineer - Luxembourg

At Julius Baer, we celebrate and value the individual qualities you bring, enabling you to be impactful, to be entrepreneurial, to be empowered, and to create value beyond wealth. Let’s shape the future of wealth management together.

The Application Engineer works within a software delivery team to design and deliver scalable, secure, and reliable software solutions. Acting as a bridge between business and technology, the role ensures applications are well‑designed, production‑ready, and compliant with architecture standards, non‑functional requirements, and regulatory constraints.

The Application Engineer supports the full delivery lifecycle — from requirements and design through implementation, release, and operations — and provides technical leadership across integration, quality, and operational readiness.
