Sr Electrical Engineer

DISA is seeking a Senior Electrical Engineer to lead the electrical engineering of DISA's HPSA® systems and minerals processing facility projects. The Senior Electrical Engineer will serve as DISA's electrical technical authority, owning the electrical design basis, power distribution design, equipment specification, and electrical safety compliance from concept through commissioning for the supply of HPSA worldwide. Based in Westminster, Colorado/Casper, WY the successful candidate will develop and review electrical deliverables, direct EPC contractor and vendor electrical scopes, and support field installation, commissioning, and operational troubleshooting at client and DISA sites. While the role is electrical-focused, candidates with instrumentation and controls (I&C) experience are strongly preferred and will contribute to the overall HPSA design including: P&IDs, instrument specifications, control philosophies, and PLC/HMI integration and programming alongside the engineering team. The successful candidate will thrive in a dynamic start-up environment, wearing multiple hats and contributing to many areas of engineering.
