Project Engineer I

Position Summary

MARS Energy Solutions is seeking a Project Engineer I 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 work and time in the field, performed with guidance and review. Recent graduates are encouraged to apply.

Responsibilities

• 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

• 0–4 years in solar PV, construction, or a related engineering field; internship or academic project experience acceptable for entry-level applicants

Skills, Knowledge & Abilities

• 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 escalate 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
