About the role

Senior CFD Engineer with plasma physics expertise focused on semiconductor manufacturing, plasma etching, deposition, and surface processing. Builds high-fidelity computational models, collaborates with data science and ML teams, and often works on-site with customers to drive engineering decisions.

Responsibilities

  • Building and owning computational plasma models for semiconductor manufacturing processes, including plasma etching, CVD/ALD deposition, and ion-driven surface interactions
  • Working directly with semiconductor customers—often on-site—to scope engineering challenges, design modelling strategies, and present results that drive process decisions
  • Selecting and applying the right simulation tools and fidelity level for each problem (e.g. COMSOL, HPEM, VizGlow, CFD-ACE+) and validating outputs against experimental or industrial data
  • Collaborating with PhysicsX Data Scientists and ML Engineers to integrate simulation work into AI-powered workflows
  • Operating independently on open-ended, highly specialised problems—scoping, executing, and delivering with minimal oversight
  • Applying industry experience ideally within or directly supporting the semiconductor manufacturing industry
  • Proficiency in Python (or similar) for workflow automation, data handling, and integration with simulation tools
  • Mentoring junior colleagues and contributing to a culture of collaboration and growth
  • Traveling globally (North America, Europe, Asia, Oceania) for an average of 3-4 weeks per quarter to work on-site with customers
  • Role evolution opportunities toward individual contributor or technical lead, owning increasingly complex semiconductor plasma projects

Qualifications

  • Deep expertise in plasma physics applied to semiconductor manufacturing (plasma etching, deposition, surface processing)
  • Strong background in computational plasma modeling (plasma chemistry, sheath dynamics, ion energy distribution, plasma-surface interactions)
  • Experience engaging with customers, often on-site, and presenting results to drive decisions
  • Proficiency in Python (or similar) for workflow automation and data handling
  • Ability to work independently on highly specialised problems and mentor others
  • Strong communication skills and ability to collaborate with cross-functional teams (data scientists, ML engineers)
  • Industry experience in or supporting semiconductor manufacturing preferred
  • Willingness to travel globally (3-4 weeks per quarter) and hybrid work model familiarity
