Job TitleSubject Matter Expert – Rail Verification & Validation (V&V)Role SummaryThe V&V SME provides deep technical leadership across the rail system lifecycle—defining strategy, processes, and evidence to demonstrate compliance, safety (SIL), RAMS, and fitness-for-purpose of signaling, rolling stock control, and integrated rail systems. The SME sets the V&V framework per CENELEC EN 50126 (RAMS), EN 50129 (system safety), EN 50716 (software—superseding EN 50128/EN 50657), and leads Independent Verification & Validation (IV&V) governance where applicable.Key ResponsibilitiesStrategy & Governance- Define the project-wide V&V strategy and management plan aligned to EN 50126/29 and EN 50716, including lifecycle activities, deliverables, and acceptance criteria (V-model). - Establish and chair V&V governance (reviews, gates, audits), ensuring independence for IV&V activities and alignment with RAMS and Safety Case development. - Author and maintain Verification & Validation Management Plan (VVMP) and Requirements Verification & Traceability Matrix (RVTM); drive configuration/change control for evidence.Requirements, Interfaces & Traceability- Lead requirements engineering for verifiability/validity; own bi‑directional traceability from hazards/SIL targets to requirements, tests, and certification evidence (DOORS/Polarion). - Oversee interface control (ICDs) and certifiable elements, ensuring integration risks are addressed early with objective evidence.Testing & Evidence- Architect test strategies (lab/HITL/simulation, on‑train/site) for functional, integration, regression, performance, and safety‑related testing across onboard/trackside subsystems (CBTC/ETCS/interlocking/TCMS). - Define test environments & tools, acceptance test procedures, defect management, and objective evidence required for Safety Case and certification. - Plan and witness T&C (Testing & Commissioning) activities as part of IV&V; issue independent findings and recommendations.RAMS & Safety Case- Lead RAMS activities (PHA, FMEA/FMECA, FTA, Markov), THR allocation, SIL justification, Safety Case authoring, and demonstration of compliance per EN 50126/29. - Ensure alignment with ISA/O‑ISA assessments and regulatory expectations; coordinate with independent bodies (NoBo/DeBo/AsBo).IV&V Delivery (when independent role applies)- Plan IV&V audits, assessments, and reporting across lifecycle phases; provide early visibility of Safety/Functionality/RAM/Quality risks and mitigation. - Manage certification readiness: compile formal certification packages (design conformance, test results, hazard closure, O&M readiness).Leadership & Enablement- Mentor project teams on best practices in requirements/testability, safety analysis, and evidence generation; run training aligned to EN 5012x. - Drive continuous improvement (KPIs, lessons learned), tool qualification, and cybersecurity considerations now embedded in EN 50716.Minimum Qualifications- Education: Bachelor’s/Master’s in Systems, Electrical/Electronics, Computer/Software, or Control Engineering. - Experience: 10–15+ years in rail systems engineering/V&V with safety‑critical systems; demonstrable track record delivering to EN 50126/29 and software standards (EN 50716 / legacy EN 50128). - Methods/Tools: DOORS/Polarion (RVTM), test management, defect tracking; RAMS analyses (FMEA/FTA/Markov); HITL/simulation; Safety Case authoring. - Standards & Assurance: Deep knowledge of SIL allocation/THR, Safety Case structure, and IV&V practice for rail programs.Preferred Qualifications- Delivery experience on CBTC/ETCS/interlocking/TCMS programs with multi‑vendor integration and complex interfaces. - Exposure to O‑ISA/ISA engagements and regulatory certification pathways (NoBo/DeBo/AsBo). - Familiarity with California HSR VVMP/IV&V practices or similar mega‑projects (evidence frameworks, CEHL, DOORS linking). - Awareness of EN 50716 cybersecurity additions and IEC 62443/CLC TS 50701 links.Core Competencies- Systems Thinking & Risk Management: Translate hazard/risk analyses into verifiable requirements and tests; anticipate integration risks early. - Technical Writing & Evidence: Produce defensible, audit‑ready documentation and certification packages. - Stakeholder Leadership: Influence design, safety, commissioning, and regulatory stakeholders; facilitate resolution of certification blockers.Key Deliverables- V&V Strategy & VVMP; RVTM; V&V dashboards and risk logs. - Test strategies/plans/cases; objective evidence bundles (reports, logs, defect closures). - RAMS analyses (PHA, FMEA, FTA), SIL allocation basis, and Safety Case. - IV&V audit reports, certification readiness statements, and final recommendations.Success Metrics (KPIs)- Requirements Coverage & Traceability: % requirements verified/validated; closed hazard actions vs. plan. - Defect Closure Effectiveness: Mean time to resolve safety‑critical defects; zero open SIL‑impacting issues at gate. - Test Maturity: % planned tests executed/passed across lab/site; evidence completeness score for certification. - Certification Readiness: Timely Safety Case approval; successful ISA/O‑ISA findings with no major non‑conformities.Tools & Platforms- Requirements & Risk: IBM DOORS / Polarion for RVTM and CEHL linkage; hazard logs. - Test & Simulation: HITL benches, emulators/simulators; automated test frameworks; lab/site data acquisition. - Assurance & Reporting: Safety Case repositories; IV&V audit templates; conformance checklists (design, construction, O&M).Working Model- Operates across design, build, integration, T&C, and entry‑into‑service; may serve as independent assessor on certain work packages per contract. - Interfaces with System Engineering, Safety Assurance (ISA/O‑ISA), Test & Commissioning, Quality, and regulatory bodies.
