Description
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 overview
The Senior Control Panel Designer owns complete electrical drawing packages for our control panels and power products, from concept through released production revision. You will design PLC and I/O hardware, network and wiring documentation, safety circuits and switchgear interfaces in AutoCAD Electrical or EPLAN P8, to UL 508A and the NEC.
This is a new product development role, centered on our smart AI UPS and related power products. You will work day to day with controls, power electronics, mechanical, manufacturing and procurement, and help set the drawing standards the team works from.
Key responsibilities
- Carry complete drawing packages from concept through prototype, verification and released production revision, with ECO/ECN discipline
- Design PLC and I/O hardware: I/O lists, module and rack selection, I/O allocation, 24 VDC power budgets, fusing and distribution, analog signal conditioning, shielding and grounding
- Produce network interface drawings and diagrams: Ethernet and Modbus TCP topology, fiber and copper runs, managed switch port assignments, IP address schedules and panel-to-panel communications
- Create wiring detail: terminal block schedules, wire numbering, cable and conduit schedules, interconnect and field wiring diagrams
- Design emergency stop and safety circuits with our functional safety reviewers: dual-channel monitored wiring, safety relays, monitored contactors and reset logic
- Design switchgear interfaces: breaker close/trip circuits, CT and PT wiring, 125 VDC control power, interposing relays, permissives and interlocks
- Determine and document SCCR, select listed and recognized components, and size conductors, overcurrent protection and enclosures to UL 508A and NFPA 70
- Generate BOMs from schematics and maintain the component database: part numbers, manufacturer and vendor data, obsolescence tracking and revision history
- Set up and maintain symbol libraries, project templates and device tagging schemes so the team works from one shared standard
Required qualifications
- 7+ years of control panel design experience, with a track record of carrying complete drawing packages from concept through released production revision
- Strong working knowledge of AutoCAD Electrical or EPLAN P8, including setting up symbol libraries, project templates and device tagging schemes for a shared team standard
- PLC and I/O hardware design: I/O lists, module and rack selection, I/O allocation, 24 VDC power budgeting, fusing and distribution, analog signal conditioning, shielding and grounding
- Network interface drawings and diagrams: Ethernet and Modbus TCP topology, fiber and copper runs, managed switch and port assignments, IP address schedules and panel-to-panel communications
- Wiring detail: terminal block schedules, wire numbering conventions, cable and conduit schedules, interconnect and field wiring diagrams
- BOM generation from schematics and component database upkeep: part numbering, manufacturer and vendor data, obsolescence tracking and revision history that procurement and manufacturing can rely on
- Applied NEC (NFPA 70) knowledge for panel, feeder and overcurrent protection decisions, and comfort walking a reviewer through conductor sizing and enclosure choices
- Practical UL 508A knowledge: SCCR determination and documentation, listed and recognized component selection, spacing and clearance, wire bending space and field wiring terminal markings
- Emergency stop and safety circuit design: dual-channel monitored wiring, safety relay selection, monitored contactors and reset logic, with an understanding of NFPA 79 and ISO 13849 intent
- Switchgear interface familiarity: breaker close and trip control circuits, CT and PT wiring, 125 VDC control power, interposing relays, permissives and interlocks
- New product development experience, ideally on smart AI UPS or similar power products, from concept through prototype, verification and production release with ECO/ECN discipline
Preferred qualifications
- Experience with both AutoCAD Electrical and EPLAN P8, or helping move a drawing standard from one platform to the other
- Background in battery energy storage, UPS or power electronics products, including MV interfaces
- Time working alongside a UL 508A panel shop or on an NRTL field evaluation, including working through inspector findings
- Familiarity with SEL protective relays, managed industrial switches and 125 VDC control power gear
- Working awareness of IEC 61439, IEC 60204-1, NFPA 79 and ANSI/IEEE C37 as they relate to panel and switchgear design
- Some exposure to PLC programming or commissioning
- AAS or BS in electrical engineering or electrical technology, or equivalent hands-on panel design experience

About this role
ON.energy is building grid-safe data centers around its patented AI UPS technology, and this role owns the complete electrical design for the control panels and power products that make that possible. You'll move drawing packages from concept through production release, working in AutoCAD Electrical or EPLAN P8 to UL 508A and NEC standards. The work spans PLC and I/O hardware selection, network topology and wiring documentation, safety circuits, switchgear interfaces, and component database management—all while setting the drawing standards your team operates from.
This is a new product development position that demands 7+ years of control panel design experience and deep fluency in both the technical tools and the regulatory landscape. You need to own the full design cycle with ECO/ECN discipline, understand emergency stop and safety circuit logic, size conductors and overcurrent protection, determine SCCR, and communicate confidently with UL reviewers. Experience with power products like UPS or battery energy storage is preferred, as is hands-on familiarity with a panel shop or NRTL field evaluation process.
The role is based in Houston and requires in-office work. You'll collaborate daily with controls, power electronics, mechanical, manufacturing, and procurement teams—a position suited to someone who thrives on technical depth and cross-functional ownership.
