Position Summary

MARS Energy Solutions is seeking a Project Engineer II to support the design and execution of solar PV, BESS, and EV infrastructure projects. Reporting to a Senior Project Engineer and supporting the Project Manager, this role carries a genuine 50/50 split between design and field work. The PE II performs the same core engineering work as a PE I but operates with limited day-to-day supervision and helps guide more junior engineers.

Location: Rocklin, CA (Remote Eligible – U.S.-Based Candidates)

Key Responsibilities

Project Engineers split their time roughly evenly between design and field execution, reporting to a Senior Project Engineer in support of the Project Manager.

• Support early-stage design — preliminary PV layouts and stringing concepts in Helioscope and AutoCAD — feeding the engineering team’s basis of design
• Produce CAD design work including line-side tap detail drawings, collaborating with the Engineering Director and field operations team on PE-stamped sets
• Support drawing package revisions through design and construction to an approved-for-construction set
• Process submittals and RFIs through Procore — no material installed without an approved submittal, no field change on a verbal approval
• Support procurement accuracy and vendor coordination against the construction schedule
• Provide technical support for utility interconnection and AHJ permitting, including technical responses and supporting the path to PTO
• Support Methods of Procedure (MOPs) for outage and tie-in work
• Conduct site visits to verify installation conforms to IFC drawings and support crews at key milestones
• Support pre-energization documentation in adherence with the MARS Build Standards
• Support commissioning — DC string testing, IR survey coordination, and deficiency tracking
• Maintain as-built redlines in Procore and photograph concealed work prior to cover
• Own project closeout coordination to the MARS “O&M Ready” standard, with full turnover documentation
• Assist Business Development with pre-contract due diligence and site assessments

Experience & Education

• 4+ years in solar PV design, project engineering, or a closely related field
• Carries the responsibilities above across multiple concurrent projects with limited supervision, including interconnection from application through PTO
• Bachelor's Degree in Electrical Engineering, Civil Engineering, or a related technical field; equivalent experience considered, ABET accredited degree a plus.

Skills, Knowledge & Abilities

• Comfortable splitting time between design/office and active field work — not a pure desk job
• Working knowledge of Helioscope, PVSyst, AutoCAD, and Procore
• Understanding of NEC and solar PV components; California Electrical Code a plus
• Able to read construction drawings, structural plans, and single-line diagrams
• Understands that deviations require documented engineering disposition — verbal approvals do not count
• Strong communication across clients, contractors, utilities, and AHJs; willing to stop work and elevate when the field conflicts with approved drawings

Physical Demands & Work Environment

• Walk active sites, climb ladders/stairs, lift up to 50 lbs.
• Frequent travel to project sites; work outdoors in varying conditions
• Medical, Dental, and Vision Insurance
• Company-paid Life and AD&D Insurance
• 401(k) Retirement Plan with Company Match
• Paid Time Off (PTO)
• Paid Company Holidays (x6)
• Opportunities for professional growth and career development
