Job description

We are seeking an experienced RAMS Engineer to support railway vehicle refurbishment, modernization, and retrofit programs. The RAMS Engineer will be responsible for applying

Reliability, Availability, Maintainability, and Safety (RAMS) principles throughout the refurbishment lifecycle to ensure that refurbished rail vehicles and their systems meet applicable customer, contractual, safety, reliability, and performance requirements.

This position will work closely with Engineering, Quality, Manufacturing, Project Management, Testing & Commissioning, and Maintenance teams to identify and mitigate system risks, analyze failures, support verification and validation activities, and ensure appropriate RAMS documentation is developed and maintained.

The ideal candidate has experience with rail vehicles, rolling stock, transportation systems, railway equipment, or other safety-critical systems, and understands how to apply RAMS methodologies in a complex engineering and refurbishment environment.

Essential Duties and Responsibilities

• Develop and maintain RAMS plans, requirements, analyses, reports, and supporting documentation for rail vehicle refurbishment and modernization projects.
• Review customer and contractual RAMS requirements and translate them into engineering and project requirements.
• Perform reliability, availability, maintainability, and safety analyses for rail vehicle systems, subsystems, and components.
• Conduct and maintain FMEA/FMECA, Fault Tree Analysis (FTA), Hazard Analysis, Risk Assessments, and other RAMS-related analyses.
• Identify critical failure modes, safety hazards, single-point failures, and system-level risks.
• Develop mitigation and corrective actions and monitor their implementation through the project lifecycle.
• Support the development and maintenance of hazard logs, risk registers, failure reporting, and corrective action documentation.
• Analyze field failures, test failures, warranty issues, maintenance records, and operational data to identify reliability trends and recurring problems.
• Perform and support root cause analysis (RCA) and develop recommendations for corrective and preventive actions.
• Establish and monitor RAMS performance indicators, including reliability, availability, failure rates, downtime, and maintainability metrics.
• Support reliability prediction, MTBF/MTTR analysis, maintainability assessments, and life-cycle reliability evaluations.
• Work with Design Engineering to evaluate proposed modifications and their impact on system reliability, safety, maintainability, and performance.
• Review engineering changes, replacement components, upgraded systems, and retrofit designs for RAMS implications.
• Support verification and validation (V&V), qualification testing, functional testing, environmental testing, and vehicle-level testing.
• Review test plans and test results to ensure RAMS requirements are adequately verified.
• Support investigation and resolution of failures identified during vehicle refurbishment, testing, commissioning, and field operation.
• Work with Quality and Manufacturing teams to identify process-related risks affecting vehicle reliability and safety.
• Collaborate with suppliers and subcontractors regarding component reliability, failure modes, safety requirements, and corrective actions.
• Support customer meetings, technical reviews, design reviews, and RAMS-related presentations.
• Prepare clear and accurate engineering reports and documentation for customers, internal management, and project teams.
• Ensure RAMS activities and documentation are completed in accordance with applicable railway standards, customer requirements, project specifications, and company procedures.
• Participate in continuous improvement initiatives to improve the reliability, safety, maintainability, and availability of refurbished rail vehicles.
• Perform other duties as assigned.

Required Qualifications

• Bachelor's degree in Reliability Engineering, Systems Engineering, Mechanical Engineering, Electrical Engineering, Transportation Engineering, or a related engineering discipline.
• 3+ years of experience in RAMS, reliability, systems engineering, safety engineering, or a related field.
• Experience applying RAMS methodologies to railway, rolling stock, transportation, industrial, aerospace, automotive, or other safety-critical systems.
• Demonstrated experience with FMEA/FMECA, Fault Tree Analysis, Hazard Analysis, Risk Assessment, and Root Cause Analysis.
• Understanding of reliability and maintainability concepts, including MTBF, MTTR, failure rates, availability, and reliability growth.
• Ability to analyze technical data, failure information, test results, and maintenance records.
• Strong technical writing and documentation skills.
• Ability to read and interpret engineering drawings, specifications, schematics, test reports, and technical documentation.
• Strong communication and cross-functional collaboration skills.
• Proficiency with Microsoft Office, particularly Excel, Word, and PowerPoint.

Preferred Qualifications

• Direct experience with rail vehicles, passenger rail, subway/metro vehicles, commuter rail, light rail, or rolling stock refurbishment.
• Knowledge of railway RAMS and safety standards, including applicable EN 50126/IEC 62278, EN 50128/IEC 62279, EN 50129/IEC 62425, or equivalent railway standards.
• Familiarity with EN 50126 RAMS lifecycle principles.
• Experience developing or maintaining Hazard Logs and Safety Cases.
• Experience with FRACAS (Failure Reporting, Analysis and Corrective Action System).
• Experience with reliability prediction and statistical analysis.
• Experience with Weibull analysis, reliability growth, life-cycle analysis, and statistical reliability methods.
• Experience with electrical/electronic systems, controls, HVAC, doors, braking systems, propulsion, passenger information systems, or other rail vehicle subsystems.
