Position SummaryMARS 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.

Key ResponsibilitiesProject 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
