We’re on a mission to do something really, really small. You’ll craft the masks that bring our patterns to life.
Lace Lithography is seeking a highly experienced Senior Optimization Engineer to join our Mask Design team. In this high-impact role, you will architect and deploy the advanced nonlinear optimization engines that define the theoretical limits of our lithography systems.

In our company we build chip lithography technology that will enable the next 100 years of chip manufacturing. Founded in 2023, we’re based in Bergen (Norway) and Barcelona (Spain), and backed by some of the world’s most ambitious investors.

Working alongside physicists and developers, you will deliver high-performance solutions to critical manufacturing challenges.

This role is based in Barcelona,



and will involve regular travel between our two locations throughout the year.

What you’ll do

-
- Advanced Algorithm Engineering: Design and engineer custom, large-scale nonlinear optimization algorithms. You will move beyond standard implementations to develop specialized heuristics and globalization strategies that exploit the specific structure of our problem.
- Complex Mathematical Formulation: Translate intricate multiphysics phenomena into rigorous, differentiable optimization problems, ensuring well-posedness and numerical stability for complex engineering objectives.
- Deep Solver Integration & Customization: Go beyond basic API interfacing to deeply customize solver behaviors. You will modify linear algebra backends, Hessian approximations, and callback structures to maximize solver performance.
- Code Implementation: Write highly optimized, modular, and testable scientific code in Julia, Python, or C++.
- GPU-Accelerated Optimization: Impleme
