Cooling Engineer - Propulsion

At BETA Technologies, we apply our intellectual curiosity, passion for aviation, and commitment to sustainability toward a shared mission of revolutionizing electric aviation. Regardless of the position one holds, each team member brings their talent and desire to positively impact the environment and lives of others in a refreshing, vibrant, and inclusive culture. Not only do we design, analyze, build and test the motors and inverters, we also develop manufacturing tooling and validation equipment such as propeller stands, dynos, bench top test rigs. Our design to validation cycle is extremely rapid and we own it all. If you love to influence design, analyze, build, test and validate your ideas at a fast pace, you’ll be happy at Beta.The Propulsion Cooling Engineer will contribute to the development of the cooling solutions for our Electric Propulsion units, from a blank page to a certified product. This cool engineer will help optimize the designs to meet performance requirements, optimizing the cooling path to minimize airflow while meeting efficiency and component temperature targets. Documenting the analyses, validating the boundary conditions and results by developing test plans and analyzing test data and correlating to the predictions is a key responsibility for this position. How you will contribute to revolutionizing electric aviation: Assess, understand and challenge boundary conditions from interfacing groupsPerform hand calcs, physics based simulations and CFD to ensure thermal objectives are metDocument analyses for internal reviews and certification purposesSupport definition of test plans for full engine tests on test stand or on aircraft to verify analysesCollaborate with design to ensure the most efficient products are definedCollaborate with the systems and certification team to ensure certifiability of products Minimum Qualifications: Ability to guide the design team in optimizing the cooling flowpath and performing trades on mechanical architecture to improve flowAbility to improve the design and come up with innovative, pragmatic and manufacturable solutions based on CFD resultsAbility to loft complex surfaces using CAD (Catia or equivalent)Ability to use meanline software (Bladegen, Vista or similar) to design efficient airfoils for air cooling fans, impellers, vanes, sized for the EPU conditionsAbility to perform conjugate heat transfer simulations (preferably with matlab) to simulate thermal performance while sizing new systems. These simulations are informed by existing test data, extrapolations and physics based models developed by the cooling engineerGood team, communication and leadership skills requiredAbility to work with minimal supervision and identify strategies to remove roadblocks is paramountMental flexibility and the ability to change direction based on new information is an absolute must in our fast paced environmentAbility to work hard to meet our ambitious goals and tight deadlinesGoogle G -Suite including drive, mail, calendar, docs, sheets, slides, charts, hangouts; slack, application lifecycle Above and Beyond Qualifications: Experience with CFD package (FloEFD, Fluent, etc)Experience with air cooling rotating machineryExperience with electrical motors, inverters Additional Information Physical Demands and Work Environment:The physical demands described here are representative of those that must be met by an employee to successfully perform the essential functions of this position.
