Job Summary

The Lead Power Systems Engineer serves as a senior technical leader responsible for the design, analysis, and integration of electrical power systems supporting large-scale, distributed generation programs.

This role functions as the technical lead for origination-stage solution development, translating customer requirements, load profiles, and site constraints into indicative, executable system designs. A primary focus of the position is defining how Mesa’s PowerCore™ generation platform is integrated, deployed, and scaled within large, complex site environments.

Working across origination, engineering, and project delivery functions, this position ensures customer-driven concepts are developed into practical, standardized system architectures and carried through detailed engineering, construction, and commissioning via third-party EPC partners. The role combines hands-on power systems engineering with technical leadership, bridging customer requirements, internal platform capabilities, and EPC execution to deliver reliable, repeatable power infrastructure at scale.

 

Essential Duties

• Lead origination-stage technical solutioning, translating customer requirements, load profiles, and site constraints into executable electrical system designs.


• Define system architectures, including generation sizing, redundancy strategy, electrical distribution topology, interconnection approach, and controls integration.


• Lead integration of Mesa’s PowerCore™ platform into large-scale site deployments, including aggregation, dispatch strategy, and system-level coordination.


• Develop and maintain standardized electrical frameworks that enable repeatable, programmatic deployment across a portfolio of sites.


• Perform and oversee power system studies, including load flow, short circuit, protection coordination, and arc flash analyses using tools such as ETAP, SKM, EasyPower, or PSCAD (as applicable).


• Develop core engineering deliverables, including single-line diagrams, grounding strategies, protection philosophies, and medium-voltage distribution systems.


• Support equipment selection and system integration, including generators, transformers, switchgear, and MV cabling.


• Evaluate system performance under normal, contingency, and abnormal conditions to ensure reliability, stability, and compliance with design objectives.


• Establish system reliability and availability targets, including redundancy strategies aligned with customer and operational requirements.


• Ensure designs align with Mesa standards while remaining adaptable to site-specific constraints.


• Define system control architecture, including plant-level controls, dispatch hierarchy, and integration with external systems (e.g., SCADA, EMS, BESS where applicable).


• Lead utility interconnection efforts, including technical study coordination, grid compliance, and permitting support.


• Define interconnection strategy (POI configuration, protection boundaries, distribution vs. transmission) aligned with system architecture and customer objectives.


• Interface with utilities, ISOs/RTOs, and regulatory bodies on protection schemes, operating constraints, and system integration requirements.


• Direct and manage third-party EPC partners responsible for detailed engineering and construction execution.


• Ensure design intent established during origination is maintained through detailed engineering, construction, and commissioning.


• Define and manage technical scope boundaries and interface points between Mesa, EPC partners, and customer systems (electrical, controls, and interconnection).


• Coordinate interconnection scope with EPC execution, including protection systems, SCADA/communications, and point-of-interconnection infrastructure.


• Review EPC deliverables and vendor submittals for technical accuracy, constructability, and alignment with standards.


• Identify and mitigate technical, interconnection, and execution risks across all project phases.


• Support commissioning, startup, and grid synchronization, validating system performance, operability, and compliance with design intent.


• Incorporate commissioning results, field performance data, and operational feedback into continuous improvement of system design and deployment standards.


• Serve as the technical authority for system architecture decisions, including approval of design approaches, deviations, and integration strategies.


• Act as the primary technical interface across customers, EPCs, OEMs, vendors, and internal teams.


• Partner with Sales, Project Management, Supply Chain, and Engineering to align technical solutions with cost, schedule, and execution requirements.


• Collaborate across mechanical, controls, civil, and manufacturing disciplines to ensure integrated and constructible system design.


• Drive alignment across stakeholders from concept through commissioning and operations.


• Support value engineering efforts balancing performance, cost, schedule, and lifecycle considerations.


• Contribute to continuous improvement of engineering standards, deployment strategies, and scalable system design.


• All other duties assigned.
