Senior Project Engineer
Box Power designs and deploys modular microgrid and renewable energy systems that bring reliable power to remote, underserved, and utility-resilience applications across North America. Our systems integrate solar, battery storage, generators, and advanced controls into deployable, scalable energy solutions. We move fast, solve hard problems, and are committed to making clean energy accessible everywhere it's needed.
We are seeking a highly experienced Senior Project Engineer to join our Engineering team. In this role, you will lead the technical design and engineering execution of complex microgrid and renewable energy projects from concept through commissioning. You will be the technical authority on your projects, working across solar PV, battery energy storage systems (BESS), generators, and integrated controls — while collaborating closely with Project Management, Procurement, Field Operations, and our clients.
This is a hands-on, high-impact role for an engineer who thrives in a fast-paced environment, takes ownership, and wants to see their designs deployed in the field.
Key Responsibilities- Lead full-cycle engineering design of microgrid systems including solar PV arrays, BESS, backup generators, and hybrid controls architectures.
- Develop and own the system single-line diagrams (SLDs), electrical schematics, equipment specifications, and design packages from 30% through IFC (Issued for Construction).
- Size and select major equipment including inverters, charge controllers, transformers, switch gear, battery systems, and generator sets.
- Perform load analysis, energy modeling, and system performance simulations to validate design assumptions and optimize system configurations.
- Design and specify controls and SCADA architecture for automated microgrid management and remote monitoring.
- Ensure all designs comply with internal company standards, contractual requirements, jurisdictional and utility requirements, and applicable codes and standards.
- Serve as the primary technical lead on multiple concurrent projects from NTP through commissioning and handoff.
- Develop and maintain engineering deliverable schedules aligned with project milestones and deployment timelines.
- Coordinate with AHJs, utilities, and third-party engineers for permitting, interconnection, and inspections.
- Support procurement by developing RFQs, reviewing vendor submittals, and providing technical evaluation of equipment bids.
- Provide technical support to field crews and commissioning teams during installation and startup.
- Review and respond to RFIs, submittals, and design change requests in a timely manner.
- Mentor junior and mid-level engineers, providing technical guidance and design review.
- Contribute to the development and continuous improvement of Box Power's engineering standards, templates, and design tools.
- Participate in proposal development and design basis development for new project pursuits.
- Identify and escalate technical risks proactively, proposing solutions before they impact schedule or cost.
- Bachelor's degree in electrical engineering or a closely related technical field.
- 7+ years of engineering experience with a strong focus on solar PV, BESS, generators, and/or microgrid systems.
- Demonstrated experience leading technical design of utility-scale or commercial/industrial solar + storage projects.
- Strong working knowledge of battery energy storage systems (BESS) including chemistry types, BMS architecture, integration, and safety requirements.
- Solid understanding of applicable codes and standards relevant to distributed energy systems (NEC, IBC, IFC, NFPA, UL, IEEE).
- Experience with utility interconnection processes/standards and permitting in multiple jurisdictions.
- Proficiency with electrical design tools (AutoCAD, PVsyst, Helioscope, ETAP, or equivalent).
- Strong written and verbal communication skills — able to present technical content to non-technical audiences.
- Strong organizational skills and ability to manage multiple opportunities in parallel.
- PE license (Professional Engineer) — active or ability to obtain.
- Experience with remote/off-grid and islanded…
