We are now seeking a  

• Develop computational models across multiple scales, covering methods such as molecular modeling (MD/ab initio), reaction kinetics, and continuum‑level simulations (FEM/CFD/particle tracing) 

• Build and refine simulation workflows to describe CNT nucleation, growth, orientation, and reactor‑level transport phenomena 

• Implement custom simulation codes in Python, Fortran, Matlab or similar 

• Utilize high‑performance computing technologies to accelerate simulations and minimize computational runtimes 

• Analyze simulation results, summarize insights, and propose actionable improvements for reactor design and process optimization 

• Participate in full scope of development project actions: planning, risk assessment, response to issues, execution and reporting 

• Collaborate with internal R&D teams (Synthesis, Chemistry, Analytics, Design) to align simulations with experimental validation and process development needs 

• Coordinate with external simulation partners and service providers, ensuring alignment, quality, and timely delivery 

• Document results and maintain simulation of assets in a structured, reusable, and scalable way 

• PhD (or equivalent expertise) in Computational Physics, Materials Science, Mechanical Engineering, Chemical Engineering, Applied Mathematics, or a related field 

• Strong hands‑on experience in computational modeling: molecular dynamics, ab initio/DFT, reaction kinetics, continuum modeling (FEM/CFD), or multiscale frameworks 

• Proven coding skills in Python, Fortran, Matlab, C/C++, or similar scientific computing languages 

• Ability to move fast: agile development of workable prototypes that can be cross-validated experimentally in iterative fashion 

• Strong communication skills for internal and external technical collaboration 

• Analytical mindset, ownership attitude, and demonstrated drive to deliver tangible results 

• Ability to manage complex simulation projects, coordinate with cross‑functional teams, and translate modeling insights into actionable engineering recommendations 

• Experience in overseeing outsourced engineering projects, providing technical direction and maintaining consistency with internal development plans

• Fluent in English

Nice-to-have

• Experience with COMSOL Multiphysics, Star‑CCM+, or similar multiphysics environments 

• Familiarity with GPU programming or accelerated numerical methods 

• Exposure to chemical kinetics, nucleation theory, or reactor modeling 

You will become part of a multidisciplinary R&D organization working at the forefront of CNT technology and semiconductor innovation. You will work closely with experts across synthesis, reactor development, analytics, and metrology — in an environment that values scientific excellence and rapid engineering execution.

As an entrepreneurial company, you will be a part of a dynamic and forward-looking scale-up with great team spirit and peer support. At Canatu, the following core values define who we are and who we want to be, guiding us in our day-to-day work:

• Curiosity to discover provides us with the spark that takes us out into the world to observe and find.

• Commitment to achieve is how we take those discoveries from ideas to something concrete.

• Collaboration for impact is required to develop what we create into impactful and meaningful products.

• Passion for progress keeps us working for new ways to do things for better tomorrows.

Does this resonate? It’s what defines us. Join us to do work with an impact.
