Job title: Reliability & Methods Engineer
Location: Framingham, MA

About the job

Role Purpose

The Reliability Engineer improves the reliability, maintainability, safety, and lifecycle performance of cGMP and non-cGMP manufacturing, utility, facility, and process systems.

Using asset-performance data, risk assessments, failure investigations, predictive technologies, and maintenance history, this role identifies systemic issues and implements sustainable improvements. The Reliability Engineer leads reliability investigations, preventive and predictive maintenance optimization, CAPAs, change controls, lifecycle planning, and reliability-centered improvements to single-use technology systems.

Department Description

The Site Maintenance & Reliability organization provides corrective and preventive maintenance, reliability engineering, calibration support, and technical services for site buildings, equipment, utilities, and manufacturing systems.

The organization is responsible for the reliable, efficient, and sustained operation of site assets while supporting manufacturing, project delivery, business objectives, and compliance with regulatory, quality, environmental, health, and safety requirements.

Join a global network that powers how Sanofi delivers — seamlessly, purposefully, and at scale. In Manufacturing & Supply, you'll help reimagine how life-changing treatments reach people everywhere, faster.

Main Responsibilities

Key Responsibilities

Asset Performance and Risk Management

• Analyze CMMS/EAM data, downtime, deviations, work orders, maintenance costs, condition-monitoring results, spare-parts usage, and equipment history.
• Develop reliability dashboards, bad-actor lists, Pareto analyses, repeat-failure trends, and MTBF/MTTR reporting.
• Assess equipment criticality and risk using FMEA/FMECA, reliability-centered maintenance, safety, compliance, product impact, redundancy, obsolescence, and business-continuity considerations.
• Recommend risk mitigation, monitoring, acceptance, escalation, or asset replacement strategies.

Failure Investigation and Problem Solving

• Lead root-cause investigations for recurring, complex, high-impact, or poorly understood equipment failures.
• Evaluate failed components, alarms, operating conditions, maintenance history, design information, and human factors.
• Investigate emerging reliability concerns, including degrading performance, repeat work orders, nuisance alarms, abnormal condition-monitoring results, and increasing parts consumption.
• Develop sustainable corrective actions and verify their effectiveness.

Maintenance Strategy Optimization

• Develop and optimize preventive, predictive, and condition-based maintenance strategies.
• Select appropriate monitoring technologies based on equipment criticality, failure modes, technical feasibility, data quality, and cost.
• Define monitoring routes, frequencies, alarm limits, response workflows, training needs, and program performance measures.
• Use risk, failure history, condition data, and field feedback to add, revise, consolidate, convert, or retire maintenance tasks through approved governance processes.

Work-Order and Inventory Analysis

• Review corrective, preventive, predictive, and emergency work orders to identify repeat failures, maintenance-induced events, planning gaps, parts usage, and opportunities to improve job plans.
• Monitor critical spares, long-lead components, repairable assets, shelf-life exposure, obsolete inventory, and stockout risk.
• Recommend stocking levels and inventory strategies based on asset criticality, consumption, lead time, redundancy, and supplier availability.

Reliability Improvement and Lifecycle Planning

• Lead bad-actor elimination, equipment upgrades, system modifications, and replacement recommendations.
• Develop technical scopes, lifecycle cost evaluations, business cases, implementation plans, and effectiveness measures.
• Lead reliability-related CAPAs and change requests for systemic or longer-term improvements.
• Support the development and execution of reliability-related capital projects and system modifications.

Single-Use Technology

• Lead reliability-centered improvements to single-use technology assemblies and systems.
• Evaluate failure modes, component selection, connection interfaces, operating limits, installation practices, leak risk, supplier performance, usability, standardization, and maintainability.
• Coordinate approved changes with Manufacturing, Process Engineering, Quality, Validation, Procurement, and suppliers.

Engineering and Project Support

• Provide reliability requirements for new equipment, system modifications, capital projects, commissioning, qualification, and operational readiness.
• Define equipment criticality, maintenance strategies, predictive-monitoring requirements, spare-parts needs, acceptance criteria, documentation, and training requirements.
• Participate in design reviews to confirm reliability, maintainability, accessibility, redundancy, control strategy, safe-work, and lifecycle requirements.

Technical Leadership and Compliance

• Develop and maintain reliability standards, tools, templates, and analytical methods.
• Coach engineers, planners, mechanics, technicians, and system owners in reliability principles, investigation methods, and data-driven decision-making.
• Maintain accurate, traceable, current, and inspection-ready technical documentation.
• Perform work in accordance with cGMP, data-integrity requirements, Quality Systems, site procedures, HSE requirements, OSHA expectations, engineering standards, and approved change-control processes.
• Support planned shutdowns, utility outages, start-ups, system restoration, emergency conditions, and manufacturing escalations.

Decision Rights and Accountability

The Reliability Engineer:

• Selects appropriate reliability methods, data sources, analytical tools, and assumptions.
• Determines engineering risk ratings and recommends mitigation, monitoring, acceptance, or escalation through the applicable governance process.
• Defines the technical basis for predictive-maintenance technologies, monitoring routes, alarm limits, frequencies, and response strategies.
• Recommends evidence-based changes to preventive and predictive maintenance programs.
• Prioritizes bad actors and systemic reliability improvements based on safety, compliance, frequency, cost, and business impact.
• Is accountable for the quality and timely completion of assigned analyses, investigations, CAPAs, change requests, work-order reviews, inventory-risk assessments, and technical documentation.
• Escalates significant risks, repeat failures, overdue actions, and material cost, compliance, schedule, or manufacturing exposure.

Key Deliverables and Performance Measures

• Current asset-criticality and reliability-risk assessments with documented mitigation priorities.
• Routine reporting of bad actors, recurring failures, downtime drivers, and lifecycle cost opportunities.
• Timely root-cause investigations with sustainable corrective actions and demonstrated effectiveness.
• Effective predictive-maintenance programs with actionable alerts, route compliance, avoided failures, and measurable value.
• Reduced emergency work, repeat failures, and maintenance-related downtime.
• Improved preventive-maintenance effectiveness, job-plan quality, and labor utilization.
• Timely completion of reliability CAPAs, change requests, and work-order analysis actions.
• Reduced critical-spare stockout, excess-inventory, and obsolescence risk.
• Approved single-use technology improvements that reduce failure risk and improve standardization, usability, and maintainability.
