Alten Technology The System Validation Engineer at Alten Technology is responsible for system-level validation of vehicle systems, ensuring integrated ECUs and subsystems behave as intended. This includes creating verification plans, designing test benches, executing multi-ECU testing, and supporting defect triage.

Responsibilities

Own system-level validation for assigned System Technical Specification (STS) documents, for example Thermal, Steering, Braking, Lighting, Power Management, Network, Charging. Ensure that every STS requirement has a defined verification method and test coverage
Create and maintain Design Verification Plans (DVPs) per system domain, with full requirement-to-test-case traceability.
Define system-level test configurations from the system boundary diagram, spanning one or more real ECUs connected to each other and to restbus-simulated peers in parallel, tree or other topologies.
Design, build and commission system test benches, and work with Vehicle Systems, Hardware and Firmware teams on bench readiness and on the boundary between bench, Software In the Loop (SIL) and vehicle testing
Execute multi-ECU and cross-domain integration, functional and regression testing on bench and vehicle assets, in nominal and off-nominal conditions, and analyze data to produce actionable insights
Support test automation and infrastructure planning for system DVPs so that regression coverage scales across vehicle platforms
Drive system-level defect triage and root cause analysis, track issues to closure for issue resolution, and re-test after fixes
Support the SFMEA activities led by the Vehicle Systems Integration (VSI) team: review failure modes and mitigations, provide input on testability and detection, and ensure SFMEA findings are covered by system-level tests
Provide system-level release readiness sign-off against program gate exit criteria, and report coverage, risks and mitigation plans in program reviews.

Qualification

Bonus Qualifications

Required

Bachelor's or Master's degree in Electrical Engineering, Mechanical Engineering, Computer Engineering or equivalent
5+ years of experience in vehicle system validation, system integration or systems engineering roles
Proven experience validating integrated multi-ECU systems against system-level requirements in one or more vehicle domains
Deep technical understanding of automotive communication protocols (CAN, LIN, Ethernet), network topologies and 12V power management
Hands-on experience with system-level testing, including instrumentation, restbus simulation, fault injection and advanced data analysis
Experience developing system test plans (DVPs) with requirements traceability in tools such as Polarion or IBM DOORS, informed by SFMEA analysis
Working knowledge of System Failure Mode and Effects Analysis (SFMEA), including how failure modes, effects and mitigations translate into system-level test coverage
Excellent written and verbal communication skills, with the ability to explain complex technical concepts to a multi-disciplinary team.
Bonus Qualifications:
Experience designing HIL or system test benches, including rapid prototyping tools (e.g. dSpace) and xIL environments
Experience with CI-integrated test infrastructure and test automation at scale
Experience with automotive diagnostics (UDS) and vehicle bring-up • Experience with ISO 26262 functional safety
