Thermal Mechanical Engineer

Who You’ll Work With The Thermal Engineering team addresses thermal engineering design challenges of high-end switching products. Our team collaborates closely with the Electrical design, Software, Mechanical, and Program Leaders to ensure the fulfillment of overall system requirements. As part of our team, you will be responsible for tackling all thermal design-related issues across various projects. The total estimated annual compensation range for this position, inclusive of base salary, bonus, and equity, is $220,000–$400,000. This range is a good faith estimate only. Bonus and equity are discretionary, subject to plan terms, and are not guaranteed components of total compensation. Actual total annual compensation may vary based on employee performance, company or equity performance, company policy, board approval, or similar factors. Please see additional base salary information below. What You’ll Do Work closely across cross functional teams to aid in product design, validation, and reliability of thermal solutions. Develop a validation plan to not only qualify the product but also work in design improvements to system and cooling solutions (coldplates, ducts, fans, heatsinks, and TIM). Take ownership of real products and make engineering decisions around specifications, system status, vendor deliverables, and program status to customers.  Responsibilities :  • Be one of the key voices in the thermal-mechanical solutions from concept to mass production • Perform lab tests (PQ, Thermal, Airflow, System stress testing, Environmental chamber testing, temperature mapping) • 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. • Travel to either vendor, contract manufacturer, and/or customer sites for bring up/debug of systems (typically local). Preferred experience: • BS/MS in Mechanical engineering, Electrical Engineering, or Related Engineering Discipline with 2 years of experience preferred  • 3D CAD and 2D Drawing experience (PTC Creo)  • Hands on experience in lab with high power silicon, systems, and electronics (6kW+) • Thermal Interface Material (TIM) characterization and utilization  • Coldplate or heatsink design and/or testing and qualification • CDU experience – operation and fundamental principles behind the CDU • Instrumentation of system, DOE experience, and strong root cause analysis • Scripting experience in Shell scripting, Python, Matlab, C, etc • Strong understanding of heat transfer, thermodynamics, and fluid mechanics • Understanding of telemetry, data acquisition, and thermal characterization tools • Knowledge of GD&T and manufacturing practices. Brazing, skiving, additive manufacturing, welding, and heat treatment. • Must be able to frequently lift 50lbs+ • Simulation experiences (Fluent, Thermal Desktop, IcePack, FloTherm, etc) • Liquid cooled experience in loop bring up, thread standards, corrosion practices • Fan testing, Fan PQ, and Fan Blade/Module design understanding • PID experience with pumps and fan speed controllers • Familiar with Open Compute Project (OCP) and stand
