## RESPONSIBILITIES:

- Participate in initial equipment conceptual development and carefully balance product specifications, process requirements, layout complexity, cost, and lead-time limits
- Lay out new industrial electrical control panels which are NFPA79/NEC/UL508A compliant, and create electrical, pneumatic, and fluid schematics
- Simulate processes to inform design engineers of the conceptual viability of automation proposals for cooling plants, electrical distribution, and liquid-cooling loops
- Architect, write, and debug PLC code with an emphasis on generating code that is organized, structured, documented, maintainable, and reusable for critical infrastructure applications
- Generate aesthetically simple HMI screens for complex plant and facility systems while providing sufficient feedback for troubleshooting
- Manage electrical cabinet builds, field wiring, pneumatic, and fluid plumbing
- Select and size electrical and electromechanical components such as VFDs, servo motors, and controllers
- Deploy automated processes and equipment into live campus operations, including BMS, EPMS, SCADA, and PLC systems serving chillers, CDUs, pumps, and power distribution
- Set, implement, and maintain schedules and budgets to ensure project completion

## BASIC QUALIFICATIONS:

- Exposure to industrial sensors and equipment used in cooling plants and electrical distribution (temperature, flow, pressure, leak detection, VFDs, chillers, CDUs, switchgear)
- Experience in data centers, power generation, semiconductor, or other high-reliability industrial environments
- Excellent communication skills, both written and verbal
- Experience in fast-paced iterative design and commissioning environments
- Experience solving complex problems with little to no supervision on schedule as an individual or as a member of an integrated team
