Senior Plant Engineer, Dixon - Site Services

The Position

As a Senior Plant Engineer in Facilities and Engineering, you will own the technical systems and ensure the efficient, safe, and reliable operation of critical mechanical, electrical, and process/utilities infrastructure at the Dixon and South San Francisco (SSF) sites. This high-impact, strategic role directly mitigates severe business interruption risks to critical research and manufacturing facilities, influencing multi-million-dollar investments and operational costs.

You will consult on construction, represent the organization on infrastructure initiatives, collaborate with IFM providers, and develop maintenance/operation strategies and procedures. You will work autonomously as a subject matter expert, supporting gRED Research Customers and Facilities leadership. This role combines hands-on technical system ownership with strategic data analysis to enable our mission.

• Provide technical expertise and operational support for mechanical, electrical, and process/utilities infrastructure, maximizing system uptime and ensuring equipment reliability.
• Maintain engineering documentation, risk/criticality assessments, maintenance strategies, and critical spares, overseeing the full asset lifecycle.
• Ensure reliable facility operations while applying proficient knowledge of technical standards, drawings, schematics, and codes (ASHRAE, OSHA, NFPA).
• Support audits for regulatory/internal compliance.
• Define critical spare parts, BoMs, maintenance strategies, and ensure accurate asset data in CMMS.
• Own the sequence of operations and functional requirements for equipment controlled, monitored and alarmed by the Building Automation System (BAS).
• Leverage Building Automation data and history for trending, troubleshooting, and continuous improvement.
• Develop complex PM and LOTO job plans.

• Act as system owner for critical mechanical, electrical, and process infrastructure throughout the asset lifecycle.
• Execute risk/criticality and condition assessments.
• Ensure reliability/maintainability from design through hand-over to operations for capital projects.
• Champion Reliability-Centered Maintenance (RCM) to maximize system uptime, Reliability, Maintainability, and Availability (RMA).
• Lead structured Root Cause Analysis (RCA) and Root Cause Failure Analysis (RCFA) for equipment failures and emerging issues.
• Analyze data from CMMS, BAS, and Historians for RCAs and continuous improvement.

• Comprehensive knowledge of critical facilities infrastructure including HVAC (cooling towers, chillers, refrigerated water, heating hot water), industrial/domestic water, purified water, compressed air and steam generation systems.
• Ownership of electrical infrastructure including emergency backup power, UPS, lighting, and building electrical distribution.
• Leveraging BAS knowledge and experience for troubleshooting and making corrective adjustments as needed to maintain critical environmental conditions.
• Reliability Engineering proficiency in root cause and failure analysis methods (FMEA, RCFA) and statistical process control.
• Drive sustainability, energy efficiency, and operational improvements to reduce costs and risks.

• BA/BS in Mechanical, Chemical, Industrial engineering or equivalent technical field.
• Minimum 8 years of relevant mechanical, electrical, and process/utilities infrastructure design/operation experience in high-tech, industrial, life sciences, or chemical manufacturing.
• Minimum 3 years of experience in a large, multi-functional campus environment.
• Proficient knowledge of BAS and CMMS (e.g., SAP, Siemens).
• Working knowledge of industry standards (ANSI/ASHRAE, NEMA, NFPA, EPA, OSHA) and documentation (P&IDs, process flow diagrams).
• Proven experience investigating, troubleshooting, and correcting mechanical, electrical, and process/utilities infrastructure equipment/systems.
• Experience in plant engineering across R&D, manufacturing, and commercial operations.
• Demonstrated experience optimizing equipment operation for efficiency and reliability.
• Excellent interpersonal…
