About the role

Key responsibilities & impact

Work closely with system engineering, software development, calibration, testing and validation stakeholders to identify solutions to customer needs.
Lead planning and execution of work in consultation with test environment customers, technical leaders and management as necessary to support program imperatives.
Engage with cross functional team members (within and outside of the immediate agile scrum team) to coordinate on-time delivery to meet requirements.
Create and maintain simulation models (such as Plant, sensors and actuators, serial data communication and controller models) for creating xiL Test Environments.
Evaluate, parametrize, and tune the test environment based on system requirements and calibrations.
Close partnership with test environment users to root cause and address unexpected test results and resolve issues encountered during test execution.
Provide technical support for test environment user activities.
Plan, communicate, and coordinate test environment strategy and model/hardware rollout to support applications and features requested by user community as needed.
Assist initiatives to benchmark and adopt next-generation simulation technology and tools.
Perform test environment correlation activities based on experimental data.
Support HIL bench and controller testing (including automated tools)
Create, maintain, and improve standard architectures.
Work closely with sources of models and equipment to make sure that common models and other simulation assets are shared between test environment domains and architectures.
