The Role

We’re hiring a Senior Software Developer to lead the development of simulation software that’s redefining how new materials are designed. You’ll work hands-on with Python, C, and C++, building advanced scientific software from scratch. This role is for someone with deep knowledge of phase-field methods and a strong grasp of material science, ready to take ownership of the codebase in a highly technical and mission-driven environment.

The Company

Is a deep-tech scale-up spun out from DTU (Danish Technical University) on a mission to revolutionize material discovery. Traditionally, new materials are developed through costly, manual lab testing. Their simulation tools radically accelerate this process—saving time, reducing waste, and opening the door to entirely new classes of sustainable materials. Backed by top-tier VCs and with recent funding secured, we’re scaling fast. The team is currently 8 people, growing to 25 over the next year, with a diverse, ambitious culture rooted in science and real-world impact.

Job Scope

• Develop scientific simulation software focused on phase-field modeling

• Design, write, and optimize performance-critical code in C, C++, and Python

• Collaborate with fullstack developers to bring simulation results into usable tools

• Work closely with customers and the CTO to align development with real-world needs

• Focus exclusively on onsite collaboration (remote work is not offered)

• Possibility to grow into project or team leadership over time, based on performance

Ideal Candidate

• Solid experience with phase-field methods and scientific software development

• Strong programming skills in C++ and C (Python is a plus)

• Experience with simulation software, numerical methods, or computational mechanics

• PhD in materials science or phase-field simulation is a strong plus – but not required

• Open to candidates with mechanical engineering backgrounds, provided technical experience is clear

• Proven ability to drive and manage a software codebase – GitHub or similar examples welcome

• Structured, analytical mindset with a high level of independence

Benefits

• Equity/warrents as part of the package - being an active, involved partner in the jouney toward unicorn status

• Full-time onsite role in Søborg, Denmark

• Private health insurance

• Flat structure and close collaboration with founders

• High-impact work in an emerging field with massive potential

• Potential for equity/warrants (not mentioned in public job ads)

Start date: As soon as possible.
