About the role

Key responsibilities & impact

Work closely with software development, calibration, validation, and test-environment users to translate customer needs into testable system requirements and solutions.
Create and maintain simulation models (e.g., plant, sensors and actuators, serial data communication, controller models) to build and enhance HIL/SIL test environments.
Design, integrate, and support HIL benches, including harness design, power distribution, integration of key ECMs, and use of ISO SPI, CAN tools, and INCA.
Plan, communicate, and coordinate test-environment strategy and model/hardware rollout to support applications and features requested by the user community.
Partner with test-environment users to investigate, root cause, and resolve issues and unexpected test results encountered during test execution.
Lead systems engineering activities, including requirements specification and balancing, functional decomposition, complex design analysis, and software anomaly resolution for current, new, and major programs.
Provide, communicate, and champion common best practices within the software community; perform as Subject Matter Expert (SME) for at least one platform or application component.
Apply Agile principles, DFSS tools and methodologies, and Lean thinking to continuously improve HIL engineering processes and daily work.
Work with sources of models and equipment to ensure common models and other simulation assets are shared and reused across test-environment domains and architectures.
