Position Details
Your Tasks
The position is associated with the Math+ funded project “Solution Techniques for Mixed-Integer Nonconvex Optimization.” The project develops new algorithmic techniques for solving mixed-integer nonlinear optimization problems with non-convex objectives within a Branch-and-Bound framework. Its goal is to enable globally optimal and scalable solutions by combining methods such as convexification, spatial branching, and first-order optimization approaches.
Your Profile
- Completed university degree (Master’s or equivalent) in Mathematics, Computer Science, Operations Research, or a related field
- Strong background in optimization (especially MINLP), convex/non-convex analysis, and algorithm design
- Experience with scientific programming (preferably Julia; alternatively Python, C++, etc.)
- Familiarity with optimization frameworks and solvers (e.g., MIP, SCIP)
- Knowledge of Branch-and-Bound, first-order methods (e.g., Frank-Wolfe), and global optimization techniques
- Experience with experimental evaluation and benchmarking
- Interest in interdisciplinary collaboration
- Very good English language skills
What you can expect
We offer a friendly work environment with flexible work and meeting times, excellent equipment and a challenging professional environment
as well as
- an active onboarding process to provide new employees with the skills and knowledge that are important to their success in our institute and their careers,
- a varied, future-oriented and responsible field of activity,
- professional training opportunities and support in professional development,
- an additional pension scheme (VBL),
- 30 days annual leave, flexible working hours (flexitime),
