Director of Systems Engineering

ON.energy is setting the standard for large load interconnection. ON’s patented AI UPS™ is a medium-voltage UPS that serves as a firewall, protecting the data center from the grid, and the grid from the data center. With multiple gigawatts currently under construction, we are enabling grid-safe data centers. 

Role Objective 

• Lead ON.energy’s Systems Engineering team and the practices that translate product strategy, customer needs, grid requirements, and technology opportunities into complete, verifiable system solutions. 

• Establish practical systems engineering governance across product architecture, requirements, interfaces, technical risk, verification, qualification, and design transfer. 

• Build team capability and technical ownership for grid-scale energy storage, power conversion, UPS, and advanced power quality products from concept through field deployment. 

Team Leadership and Capability 

• Lead, coach, and develop Systems Engineers; define roles, ownership, capability gaps, hiring priorities, and workload balance across active product and customer programs. 

• Set objectives, provide feedback, support performance management, and build the technical depth required for ON.energy’s product roadmap. 

• Act as product lead engineering interface to sales, sales engineering, and project engineering 

Systems Engineering Practice and Governance 

• Define and improve the lifecycle for concept definition, requirements, architecture, interfaces, design reviews, technical risk, verification planning, configuration control, and design transfer. 

• Establish practical templates, tools, review criteria, decision records, interface documents, and evidence expectations without creating unnecessary process burden. 

Product Architecture and Technical Direction 

• Guide system architectures for grid-scale energy storage, power conversion, UPS, and advanced power quality products across performance, safety, controls, protection, thermal, mechanical, cybersecurity, serviceability, and lifecycle requirements. 

• Assign design authorities, resolve cross-disciplinary conflicts, and ensure structured trade studies covering performance, cost, schedule, manufacturability, supplier capability, reliability, and product risk. 

• Document major technical decisions, assumptions, constraints, and rationale in a way that can be reused across future programs. 

Requirements, Interfaces, and Risk 

• Ensure requirements are complete, testable, traceable, and aligned with product strategy, customer commitments, regulations, grid codes, and standards. 

• Oversee disciplined flow-down to subsystems, components, software, controls, verification, and release criteria. 

• Establish management of electrical, mechanical, thermal, controls, communications, and operational interfaces across internal teams, suppliers, customer systems, and project applications. 

• Maintain technical risk visibility across the product portfolio and drive early retirement through modeling, prototyping, supplier testing, design reviews, and root-cause investigations. 

Verification, Qualification, and Product Execution 

• Direct system-level verification and validation linking requirements to analysis, simulation, inspection, hardware testing, and field evidence. 

• Define acceptance criteria, evidence plans, review readiness, and qualification strategy early in the product lifecycle. 

• Coordinate qualification across laboratory, factory, national lab, supplier, and field environments. 

• Align product intent, technical scope, schedules, and release criteria with Product Management, Program Management, discipline engineering, Supply Chain, Operations, Deployment, and Service. 

• Set expectations for supplier technical deliverables, reviews, interface compliance, and qualification evidence; ensure validated designs transition effectively into manufacturing, commissioning, and service. 

Stakeholder Communication 

• Present architecture, decisions, risk, requirements maturity, verification status, interface dependencies, and review readiness clearly to leadership and cross-functional stakeholders. 

• Coordinate communications and engineering efforts across integrated product teams of disciplinary subject matter experts and product managers who report into other functional leaders 

• Represent Systems Engineering in strategic customer, partner, supplier, standards, and technical due diligence discussions. 

Experience and Requirements 

• B.S. in Electrical Engineering, Systems Engineering, Mechanical Engineering, or a closely related field; M.S. or Ph.D. preferred. 

• 12+ years in complex power, energy, industrial, or electromechanical product development, including significant systems engineering responsibility and leadership of technical teams. 

• Demonstrated success managing and developing Systems Engineers or multidisciplinary teams, including resource planning, hiring, performance management, and capability development. 

• Proven success leading products through concept, requirements, architecture, detailed development, qualification, production release, and field deployment. 

• Direct experience with grid-scale BESS, power conversion systems, uninterruptible power supplies, or adjacent power and energy hardware is strongly preferred. 

• Strong command of requirements engineering, architecture, interface control, trade studies, technical risk, verification and validation, configuration management, and design review governance. 

• Working knowledge of relevant grid, safety, product, and reliability standards, with the ability to resolve complex issues and communicate clearly with engineers, executives, suppliers, and customers.
