Sr Electrical Engineer
About The Position
DISA is seeking a Senior Electrical Engineer to lead electrical engineering for its HPSA® systems and minerals processing facility projects. The role serves as DISA’s electrical technical authority, responsible for the electrical design basis, power distribution design, equipment specifications, and electrical safety compliance from concept through commissioning for worldwide HPSA supply. Based in Westminster, Colorado or Casper, Wyoming, the engineer develops and reviews electrical deliverables, directs EPC contractor and vendor electrical scopes, and supports field installation, commissioning, and operational troubleshooting at client and DISA sites. The position is primarily electrical-focused, with instrumentation and controls (I&C) experience strongly preferred. I&C contributions may include P&IDs, instrument specifications, control philosophies, and PLC/HMI integration and programming alongside the engineering team. The role suits someone comfortable in a dynamic start-up environment, taking on varied responsibilities across engineering. The engineer also contributes to project estimates, proposals, project scoping, technical pricing, drawing control, and as-built documentation; mentors engineers and designers; coordinates across DISA teams; and supports product improvement and intellectual property initiatives. Domestic and international travel is required as needed for design reviews, vendor inspections, commissioning, and client meetings.

- 10 or more years of relevant electrical engineering experience in mining, minerals processing, chemical, or heavy industrial facilities, with demonstrated progression in technical responsibility.
- Proven experience designing low- and medium-voltage power distribution systems, including one-line diagrams, load lists, switchgear, transformers, MCCs, VFDs, grounding, lighting, and cable/raceway systems.
- Experience performing or managing power system studies (load flow, short circuit, protective device coordination, and arc flash) using ETAP, SKM, EasyPower, or equivalent.
- Working knowledge of NEC (NFPA 70), NFPA 70E, IEEE standards, hazardous area classification (NEC Articles 500/505), and MSHA/OSHA electrical requirements.
- Ability to learn electrical standards and requirements for different regions throughout the world.
- Experience with AutoCAD; the posting’s statement about developing experience is incomplete.
- Experience reviewing EPC contractor and vendor electrical deliverables and supporting procurement, construction, and commissioning.
- Hands-on field experience with installation, FAT/SAT, commissioning, and troubleshooting of industrial electrical systems.
- Ability to support the varied responsibilities of an engineering role in a dynamic start-up environment.
- Ability to travel domestically and internationally as required.
- Compliance with DISA policies and procedures and participation in required safety trainings.
Nice To Haves
- Professional Engineer (PE) license in Electrical Engineering, or eligibility to obtain one.
- Experience specifying and selecting field instrumentation, including pressure, flow, level, density, and analytical instruments and control valves.
- Experience developing or reviewing P&IDs, instrument indexes, I/O lists, and loop diagrams.
- Experience with PLC/DCS and HMI/SCADA systems; Rockwell/Allen-Bradley is preferred.
- Experience with industrial communication networks, including EtherNet/IP, Modbus, and HART.
- Experience developing control philosophies, cause-and-effect matrices, and interlocks; familiarity with functional safety.
- Experience with high-horsepower motor drives and high-pressure pumping systems.
- Instrumentation and controls (I&C) experience.
Responsibilities
- Serve as DISA’s electrical technical authority and establish and maintain electrical design standards, specifications, and the electrical design basis for HPSA systems and facility projects.
- Develop, review, and approve electrical deliverables, including one-line diagrams, load lists, power distribution layouts, MCC and VFD schedules, panel schedules, cable schedules and sizing, grounding, lighting, and hazardous area classification drawings.
- Size and specify transformers, switchgear, switchrooms, MCCs, VFDs, motors, high-horsepower pump drives, generators, and UPS systems.
- Perform or direct load flow, short circuit, protective device coordination, and arc flash studies, and implement resulting labels and settings.
- Define electrical scope for HPSA skids and modular systems, including control panel design, power interfaces, and site utility requirements.
- Review and approve EPC contractor and vendor electrical drawings, calculations, and submittals for compliance with DISA standards and applicable codes.
- Coordinate with utilities and clients on service sizing, power supply requirements, and site electrical interfaces.
- Lead electrical safety aspects of engineering design, including NFPA 70E compliance, arc flash mitigation, and lockout/tagout provisions for DISA equipment.
- Participate in HAZOPs, design reviews, and constructability reviews, representing electrical and I&C disciplines.
- Support FAT, SAT, installation, commissioning, start-up, and troubleshooting at DISA and client sites.
- Support I&C design, including instrument specifications and data sheets, P&IDs, I/O lists, control philosophies, cause-and-effect matrices, and PLC/HMI integration.
- Prepare electrical cost estimates and contribute to proposal development, project scoping, and technical pricing inputs.
- Maintain electrical drawing control, revision management, and as-built documentation.
- Supervise and mentor engineers and designers and provide technical guidance on electrical and I&C matters.
- Coordinate with Engineering, R&D, Technical Services, Operations, and Business Development to support project delivery, equipment sales, and product development.
- Identify product improvement opportunities and support intellectual property development initiatives.
- Provide regular project, schedule, and technical updates to management.
- Travel domestically and internationally as required to support design reviews, vendor inspections, commissioning projects, and client meetings.
- Abide by DISA policies and procedures and attend and participate in required safety trainings.
- Perform other duties as assigned by the supervisor.
