- Develop functional flows, block definition diagrams, behavioral models, system architectures, and Interface Control Documents.
- Allocate requirements and functions across software, hardware, users, and external systems.
- Assist troubleshooting by reproducing failures, analyzing logs and system behavior, isolating causes across subsystem boundaries, and recommending corrective actions.
- Perform change-impact analysis across requirements, architecture, interfaces, implementation, risks, and verification.
- Advise V&V teams on acceptance criteria, test coverage, failure scenarios, and expected system behavior.
- Lead or support FMEAs, define mitigations, assess residual risk, and ensure mitigations are implemented and verified.
- Support design, integration, technical reviews, defect investigations, and release-readiness decisions.
- Develop prototypes, simulations, test tools, or production software when needed to reduce technical risk or support delivery.
- Provide technical leadership and mentor junior software developers and systems engineers through design guidance, artifact and code reviews, troubleshooting support, and knowledge sharing.
