  • A master's degree, or a bachelor's degree and 2 years of directly related experience, or an associate's degree and/or 4 years of directly related experience, or a high school diploma/GED and 6 years of directly related experience.
  • Strong technical knowledge of utilities, mechanical maintenance, maintenance execution, and equipment troubleshooting in a Good Manufacturing Practice (GMP) manufacturing environment.
  • Ability to provide technical oversight, influence maintenance execution, and guide technicians and contractors without direct people-management accountability.
  • Strong analytical and science-based problem-solving skills, including supporting troubleshooting, Root Cause Analysis, Corrective and Preventive Action (CAPA) implementation, and continuous improvement.
  • Proven experience working in a GMP environment, with awareness of safety, compliance, documentation, and maintenance quality requirements.
  • Experience managing contractors, vendors, and third-party service providers for routine, non-routine, and improvement maintenance activities.
  • Ability to communicate complex technical ideas clearly and practically to non-engineering stakeholders.
  • Ability to work effectively with Manufacturing, Maintenance, Engineering, Quality, EHS, Planning and Scheduling, System Owners, contractors, and vendors.

Responsibilities

  • Provide field-based technical oversight for utilities and mechanical maintenance, including equipment walkdowns, live troubleshooting, work execution support, and technical resolution of mechanical equipment issues at the job site.
  • Drive maintenance and improvement activities by prioritizing field issues, following up on preventive maintenance execution, verifying job completion quality, and ensuring improvement actions are practical, executable, and effective at equipment level.
  • Collaborate with System Owners and Technicians to troubleshoot in the field, review equipment condition, investigate recurring failures, improve reliability, and strengthen preventive maintenance tasks and job plans using maintenance execution feedback.
  • Work with Planning and Scheduling to ensure work orders are field-ready, properly scoped, resourced, and executable within available maintenance windows.
  • Confirm job scope, required materials, permits, isolation needs, access constraints, and field readiness for routine and non-routine maintenance activities with Maintenance Planners and Schedulers.
  • Coordinate daily execution with Technicians and Utility Operations, including field walkdowns, job-start readiness, technical support during work, and post-work verification against safety, compliance, quality, and delivery expectations.
  • Provide on-the-floor technical guidance to Technicians during complex mechanical maintenance, support troubleshooting decisions, verify work quality, and escalate technical, compliance, or resource concerns.
  • Gather Technician feedback after job execution, review recurring field issues, and improve job plans, work instructions, procedures, tools, and spare parts based on maintenance experience.
  • Support troubleshooting, condition assessment, maintenance execution, and reliability improvement for mechanical and utilities equipment, including pumps, motors, fans, agitators, mechanical seals, valves, piping systems, HVAC, air handling units, heat exchangers, chillers, cooling towers, boilers, steam generators, air compressors, and pressure vessels.
  • Participate in Root Cause Analysis and problem solving using field observations, equipment history, Technician input, failed-part inspection, and job execution feedback to develop reliability improvements.
  • Initiate and support deviations related to Utilities operations, Maintenance, and Calibration by gathering field facts, maintenance records, equipment-condition evidence, and Technician input, and supporting associated CAPA execution.
  • Ensure maintenance work is executed and documented in accordance with Good Documentation Practice, including accurate field records, work order closeout, and computerized maintenance management system (CMMS) updates.
  • Develop and improve maintenance procedures, work instructions, and job plans based on field execution feedback, equipment walkdowns, Technician input, and recurring maintenance issues.
  • Develop, implement, and continuously improve technical training, qualification programs, and individual competency roadmaps for maintenance personnel in calibration and electrical disciplines, ensuring competency progression, GMP compliance, and alignment with site operational needs.
  • Capture and share practical maintenance knowledge from field troubleshooting, lessons learned, recurring failures, equipment walkdowns, best practices, technical standards, and Technician experience to support knowledge retention and workforce capability development.
  • Assess Technician technical proficiency through field observations, practical assessments, and coaching engagements to identify technical gaps, development opportunities, and qualification support needs.
  • Coordinate and oversee contractors and vendors during field execution, including job-scope confirmation, site readiness, work-quality checks, technical issue resolution, knowledge transfer, and post-work verification.
  • Define contractor technical expectations and assess contractor work quality during major maintenance activities, shutdown support, field execution, and post-work verification.
  • Support project handover, commissioning, qualification, system walkdowns, punch-item closure, critical component identification, spare-parts identification, and maintenance-plan development for new or modified systems.
  • Develop, execute, and perform work safely in accordance with Amgen safety requirements, including lockout/tagout, Job Hazard Analysis, risk assessment, safe work procedures, and applicable EHS expectations.

Desired Qualifications

  • Experience with computerized maintenance management system (CMMS) work order management, preventive maintenance, job plan improvement, maintenance procedures, and schedule coordination.
  • Experience developing or supporting technical training frameworks, qualification programs, Technician competency assessments, knowledge repositories, or contractor technical governance programs.
  • Knowledge of digital and analytical tools such as Excel, Power BI, Tableau, Smartsheet, Spotfire, or similar tools.

Amgen develops and makes biologic medicines, which are drugs built from proteins and antibodies grown in living cells, for serious conditions such as heart disease, cancer, and bone loss. Its anemia drug Epogen, approved in 1989, became one of the biotechnology industry's first blockbuster medicines. Amgen grows these drugs in large tanks called bioreactors, and its products include the cholesterol drug Repatha, the bone-building drug Evenity, and the severe asthma drug Tezspire. It earns money by selling these medicines, mostly through large drug wholesalers that supply hospitals and pharmacies. Amgen was founded in 1980 and is based in Thousand Oaks, California.
