Summary
🤩
Rockstar🎓
Top SchoolAlexander Jaust is a Principal Software Engineer and team lead based in Bergen, Norway, with a decade of experience blending applied mathematics, high-performance computing and software engineering. He holds a PhD in computational and applied mathematics and has driven research-grade numerical methods into production, notably parallel coupling methods and GPU-friendly seismic processing pipelines. At Equinor he combines hands-on coding, security stewardship as his team’s Security Champion, and practical ML tool packaging across platforms. An active open-source contributor, he improved C bindings and Python packaging for the widely used preCICE coupling library and maintained its Spack packaging to ease reproducible multi-physics workflows. Colleagues rely on him to translate mathematically complex problems into maintainable, performant code and to mentor teams on simulation software engineering and reproducible HPC practices.
