• Collect and analyze test data. Present to internal teams, vendors, and customers in a clear and concise manner.

• Simulate current systems to validate test data to models with either Macroflow, Ansys EDT, FloTherm, IcePack, etc

• Identify thermal risk and blockers and recommend design changes

• Generate technical documentation for vendors, contract manufacturers, and customers. Communicate to key stakeholders

• Continuous improvement of lab and team in either equipment, design strategy, product quality, turn around, as well as workflow

• Leverage and develop automated workflows, develop scripts using Python, Matlab, etc.

• Work with Hardware and Software Teams to bring up and validate systems

• Bring up next generation switches from system to rack level.
