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,ROwater 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 onFGas/GWP reduction, water stewardship, metering/data integrity, and initiatives to lower the carbon footprint whilemaintainingvalidated states and utility quality.
Principle Responsibilities Utilities Operations 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, cleancompressed gases); monitor trends, respond to alarms, and execute precision maintenance to improve uptime, MTBF, and energy performance, including chiller/coldroomsequencing and validated-state protection.
AI 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 document, qualify, and sustain improvements across boiler rooms, chiller plants, WFI skids, PW loops, and AHUs.
Compliance ensure utilities remain in a validated state and compliant with GMP, HPRA/FDA, EHS, environmental, andFGasrequirements (registers, leak checks, recovery logs, phase-down plans, end-of-life handling).
Quality complete risk assessments (HAZOP), support audits/inspections, and drive safe systems of work and permit-to-work adherence for utilities and sustainability initiatives.
Troubleshooting 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, andcoldrooms.
Project Support 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/watersavings; 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 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 asrequiredtomaintaincompliant 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); maintainFGascompliance 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 andcoldrooms/freezers, metering/sub-metering, and CIP/SIP interfaces.
Commissioning competent with P familiarity with SPC, FDD, andbasic scripting or data tools (e.g., Excel/Power BI or similar); strong understanding of CSV and data integrity requirements.
Lean Green Belt or equivalent experience is beneficial.
Regulatory 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/energymodeling, heat pump integration for WFI pre-heat/return loops, advanced chiller/steam controls, vibration/condition-based monitoring, power quality analysis, and ISO ***** energy management or IPMVP M 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 areadvantageous.
