Position Summary

The Utility Sustainability Engineer is responsible for the reliable, compliant, and cost-effective operation of GMP-critical utilities supporting Drug Substance (DS) and aseptic Drug Product (DP) fill-finish, with strong emphasis on both black utilities (boilers/steam, condensate recovery, chilled/hot water, cooling towers, electrical LV/MV, HVAC plant) and clean/sterile utilities (WFI generation/storage/distribution, RO water loops, clean steam, CIP/SIP media, clean compressed gases, sterile utility interfaces). Reporting to the Senior Manager, Utilities, this role delivers day-to-day technical ownership, continuous improvement, and lifecycle management through AI-enabled/digital strategies, lean transformation, and disciplined financial stewardship. The role also supports the site sustainability program, focusing on FGas/GWP reduction, water stewardship, metering/data integrity, and initiatives to lower the carbon footprint while maintaining validated states and utility quality.

Principle Responsibilities

Utilities Operations & Reliability: Operate and optimize utility systems to meet capacity, quality, and availability targets across BDS and DP; own performance for black utilities (boilers/steam systems, chilled/hot water plants, cooling towers, electrical LV/MV, HVAC plant) and clean utilities (WFI/PW loops, clean/pure steam quality, CIP/SIP media, clean compressed gases); monitor trends, respond to alarms, and execute precision maintenance to improve uptime, MTBF, and energy performance, including chiller/coldroom sequencing and validated-state protection.

AI & Digital Execution: Build and maintain data pipelines and dashboards from CMMS, BMS/MCS, PLCs, analyzers, and historians; apply advanced analytics and support machine learning models for predictive maintenance, anomaly detection, and energy/water optimization; ensure data integrity and CSV-aligned changes with validated meters/sensors (TOC, conductivity, temperature, flow, pressure) for quality and sustainability reporting.

Lean & Continuous Improvement: Implement 5S, Standard Work, visual management, use structured problem-solving, FMEA, and RCM inputs to reduce unplanned downtime, nuisance alarms, steam/water losses, and utility energy waste; document, qualify, and sustain improvements across boiler rooms, chiller plants, WFI skids, PW loops, and AHUs.

Compliance & Qualification: Execute and maintain URS, DQ/IQ/OQ/PQ documentation, periodic reviews, alarm/limit management, and criticality assessments for black and clean utilities; ensure utilities remain in a validated state and compliant with GMP, HPRA/FDA, EHS, environmental, and FGas requirements (registers, leak checks, recovery logs, phase-down plans, end-of-life handling).

Quality & EHS: Maintain clean utility quality specifications (e.g., WFI microbiological/TOC/conductivity, clean steam dryness/non-condensable gases/superheat, compressed gas purity) and classified area environmental controls; complete risk assessments (HAZOP), support audits/inspections, and drive safe systems of work and permit-to-work adherence for utilities and sustainability initiatives.

Troubleshooting & Investigations: Lead/author technical investigations, deviations, and change controls for black and clean utilities; perform data-driven RCA and implement effective CAPAs with verification of effectiveness; deploy FDD to identify inefficiencies, leaks, sensor drift, biofilm risks, and control issues across AHUs, chillers, WFI/PW loops, clean steam generators, and coldrooms.

Project Support & Start-up: Support utilities projects, upgrades, and obsolescence programs from scope/URS through FAT/SAT, commissioning, and handover; embed metering and energy/water KPIs into design and acceptance criteria; coordinate contractor/vendor activities and ensure as-built documentation accuracy and performance guarantees for water systems, clean/pure steam, chillers, HVAC, metering, and sterile interfaces.

Financial Stewardship: Track and report utilities OPEX drivers (energy, water, maintenance, spares); identify and deliver cost and energy/water savings; contribute to business cases/CER inputs and lifecycle cost analyses; implement measurement and verification (IPMVP-aligned where applicable), manage rebates/incentives, and update budgets/forecasts with realized benefits.

Stakeholder Collaboration: Partner with Operations, Quality, Validation, EHS, Facilities, Digital/IT, and Finance for scheduling, shutdown coordination, change control, and right-first-time execution; align with site sustainability governance (Scope 1/2 reductions, refrigerant emissions, water stewardship) and support internal/external reporting and audits.

Documentation & CMMS: Maintain SOPs, work instructions, P&IDs, datasheets, loop sheets, calibration records, FGas logs, and quality test records; plan and close work orders and PMs in the CMMS with high data quality and cGMP documentation standards; sustain validated metering/sub-metering documentation and audit trails.

On-Call/Shift Support: Provide out-of-hours engineering support as required to maintain compliant and continuous operations.

Sustainability Program Support (Targeted) Baseline and optimize energy in boilers, chillers, AHUs to reduce kWh, peak demand, and tCO2e; drive decarbonization (heat recovery, heat pumps, electrification, high-efficiency burners, condensate return, free cooling); maintain FGas compliance with phase-down and leak prevention; reduce WFI/PW losses and CIP/SIP media usage; design/maintain electrical, thermal/steam, water, and gas submetering with validated data traceability.

Qualifications

Experience: 3–7 years in Pharmaceutical/Biotech or highly regulated manufacturing with hands-on ownership of black and clean utility systems supporting DS and/or DP aseptic operations, and demonstrable delivery of energy/water/carbon improvements.

Technical Expertise: Working knowledge of WFI generation/storage/distribution, clean/pure steam, purified water, CIP/SIP utilities, clean compressed air/gases, HVAC/AHU for classified areas, BMS/MCS, chilled/hot water systems, boilers, cooling towers, electrical distribution (LV/MV), chillers/refrigeration and coldrooms/freezers, metering/sub-metering, and CIP/SIP interfaces.

Commissioning & Validation: Proficiency with URS, DQ/IQ/OQ/PQ, calibration/metrology, alarm philosophy, and maintaining validated states during energy and water optimizations; competent with P&IDs, URS/specs, and FAT/SAT protocols.

AI/Digital Skills: Practical experience using data historians, BMS/MCS trends, CMMS analytics, and dashboards; familiarity with SPC, FDD, and basic scripting or data tools (e.g., Excel/Power BI or similar); strong understanding of CSV and data integrity requirements.

Lean & Reliability: Demonstrated application of 5S, Standard Work, , FMEA/RCM, and root-cause tools to improve uptime, energy intensity, and maintenance effectiveness; Green Belt or equivalent experience is beneficial.

Regulatory & EHS: Solid understanding of GMP, HPRA/FDA expectations for utilities, Health & Safety regulations, environmental compliance, and FGas stewardship; experience preparing for and supporting audits/inspections, especially for clean utility systems.

Soft Skills: Strong analytical and problem-solving ability, clear written and verbal communication, stakeholder management, and the ability to work independently and in cross-functional teams with a focus on delivery and continuous improvement.

Desirable: Experience with digital twins/energy modeling, heat pump integration for WFI pre-heat/return loops, advanced chiller/steam controls, vibration/condition-based monitoring, power quality analysis, and ISO 50001 energy management or IPMVP M&V; familiarity with corporate carbon/water accounting and sterilizing-grade utility interfaces.

Education

HETAC Level 8 (or equivalent) in mechanical, chemical, electrical, mechatronics, energy, or pharmaceutical engineering, or a related engineering discipline. Advanced degree and/or certifications in energy management (e.g., CEM), refrigeration/FGas, reliability, or automation/CSV are advantageous.
