Senior Systems Engineer


At Sun Tribe Solar, we are building a team of the brightest and most passionate individuals and giving them an environment to freely think, create, grow and thrive, resulting in innovative and forward-thinking approaches to solar. The Project Engineering team’s primary goal is to progress solar PV and energy storage projects from discretionary permitting through construction by designing enduring, practical, safe, technically advanced, and cost-effective projects from 1MW to 20MW in size.

As a Systems Engineer within the Project Engineering team at Sun Tribe, you will be responsible for racking, modules, inverter selection, finalized system layout, PV system design (DC stringing, inverter configuration), Production model, and EPC budget. You will develop the final system design and coordinate with electrical project engineers by iterating system design variables which optimize project costs and asset value.

Candidates must demonstrate keen interest and knowledge of the solar PV industry and a proven ability to efficiently and effectively multi-task in a team-oriented, fast-paced environment. The Systems Engineer reports directly to the Director of Project Engineering.
