Job description

IDOM is part of the team delivering the Traction Power, Signaling, Communications and Systems design for the program's first operating segment. Our scope covers the systems that make a high-speed railway run: traction power and substations, train control, and the communications backbone — designed to the most demanding international high-speed standards and adapted to U.S. codes and practice. California High-Speed Rail is the first true high-speed rail system in the United States: a fully electrified, 220-mph railway that will transform mobility across the state and set the technical benchmark for every future high-speed program in North America. Very few engineers will be able to say they designed it. This is that opportunity.

Why this role is a career move

• Design the first 220-mph railway in America — a once-in-a-generation infrastructure program with visibility across the entire U.S. transit industry.
• Work shoulder to shoulder with IDOM's international high-speed rail experts — direct technical exchange with the engineers who have designed and commissioned HSR communications systems in revenue service.
• Grow with the program: the team is scaling through 2027 and the program horizon extends into the 2030s, with clear paths toward technical leadership and management as the U.S. practice expands.
• As a licensed PE, take real design responsibility on a landmark project — not a review desk: your engineering will be built.

Primary Duties & Responsibilities

You will join the Traction Power team, reporting to IDOM's Power Systems Manager, and take design ownership of substation and low-voltage power systems for the high-speed rail program:

• Lead the detailed design of substation LV systems and equipment: AC/DC auxiliary power, switchgear, protection and control, grounding and bonding, cabling and raceway.
• Perform and review power system studies (load flow, short circuit, protection coordination, arc flash) using ETAP or SKM.
• Coordinate interfaces with the medium-voltage and traction power design (25 kV autotransformer-fed system), utility interconnections, and Power SCADA.
• Seal design deliverables within your area of competence as a licensed PE and support submittal cycles with the design-build team and the Authority.
• Review vendor and contractor submittals and support the design through construction, testing and commissioning.
• Mentor junior engineers as the substations team grows.

Minimum Academic & Professional Requirements:

• B.S. in Electrical Engineering, or related field
• Active PE license (California).
• 8+ years of experience in substation and power systems design (utility, industrial or transit).
• Strong command of NEC, NESC, IEEE and NFPA standards applicable to substation design.
• Proficiency with power system analysis tools (ETAP or SKM) and design coordination in BIM environments.

Location

Candidates not based in Sacramento, but who are open to frequent travel to the area for project site visits will be considered as part of a hybrid arrangement (site & home). Preference will be given to candidates residing or open to relocating to the Sacramento area. Relocation support may be available for the right candidate.

• COMPETITIVE COMPENSATION – Including Incentive compensation based on company performance
• JOB ENRICHMENT AND CAREER ENHANCEMENT
• GREAT BENEFITS – Company contributions to Health Savings Accounts, medical insurance, dental insurance, short-term disability, long term disability, life insurance, flexible spending accounts, 401(k), paid time off, holiday pay, and other benefit programs
• EXCELLENT WORKING CONDITIONS
• PROFESSIONAL DEVELOPMENT- IDOM, Inc. invests in developing its professionals including job-related professional training with tuition reimbursement opportunities
• $150k-$250k per year, depending on all candidate factors, such as qualifications, experience level, etc.
• Work-Life Balance, Flexible Hours, and remote working days. Role is considered Hybrid, with some on-site work.
• Long term career path, in a multicultural and multidisciplinary environments
