Gradient’s mission is to cool the world by transforming every home to be more comfortable and healthy for the people who inhabit it — without compromising the environment. Today, heating and cooling equipment emits more greenhouse gas emissions than the entire transportation sector, and expansion in the use of cooling is projected to double these emissions in the next 30 years. However, comfortable buildings are critical for health and productivity, especially among communities who are vulnerable to the effects of climate change. Gradient’s vision is a future where everyone has access to comfortable buildings that are fully decarbonized. Our launch product is a direct-to-consumer high-efficiency and low-carbon heat pump.
We are looking for a Thermal Test Engineer to support the Thermal Team’s efforts to develop advanced technologies that reduce the environmental cost of building heating and cooling. We’re building the next generation of thermodynamic devices for an industry that hasn’t seen innovation in over 50 years. We’re looking for someone who understands both the fundamentals of scientific research and the bigger picture of our impact on global climate.
- Coordinate with thermal engineers to understand test objectives related to thermal performance and reliability, and design, build, and run tests to accomplish these goals
- Design tests to obtain high quality, repeatable data in as little time as possible
- Select test equipment according to the needs of the project: environmental chambers, fans, compressors, heat exchangers, sensors, DAQs, etc.
- Automate tests to the greatest extent possible using LabVIEW or similar software
- Design and build test fixtures using Gradient’s machine shop and/or parts from external suppliers
- Thoroughly document all test procedures, results, and conclusions
- Coordinate contractors and permitting when necessary to build large test setups
- Manage layout and policies for R+D shop space to ensure safety and optimal productivity for engineers and technicians
- Troubleshoot test failures to help determine necessary design changes
- BS or MS degree in Mechanical Engineering, with strong fundamentals in thermodynamics, fluid mechanics, and heat transfer
- Be comfortable designing, building, and running test equipment along the entire spectrum of complexity: from bench-top tests that take a day to design and build, up to large capital equipment that can take a year or more
