- 8+ years of relevant experience in nuclear, fusion, chemical/process, or other highly regulated process systems
- Demonstrated experience developing PFDs, P&IDs, process architectures, and mass/energy balances
- Experience defining system interfaces and working across multiple engineering disciplines
- Experience with tritium processing, nuclear fuel-cycle systems, isotope processing, or fusion fuel-cycle systems strongly preferred
- Experience with vacuum, gas handling, cryogenic, or high-purity process systems is a plus
