Mechanical Engineer - Aerodynamicist

Joby Aviation•San Carlos, CA

9d•$104,800 - $181,000•Onsite

About The Position

Joby Aviation is seeking an experienced mechanical/aerospace engineer with strong technical fundamentals, practical ability and problem-solving skills in turbomachinery aerodynamic & mechanical design & analysis to join our Powertrain team. As a key member of a high-performance team you will collaborate with your teammates by performing a wide variety of turbomachinery (compressor and turbine) aerodynamic and mechanical analyses and design to help them develop turbocompressors supplying pressurized air to hydrogen fuel cell systems that provide electrical power to aircraft propulsion systems. As part of a cross-functional team you will be responsible for ensuring the highest aerodynamic performance of our components with an emphasis on rapidly iterating through design/build/test cycles to achieve our ambitious performance and timing goals.

Requirements

B.S. in Mechanical or Aerospace Engineering (or equivalent) and 5+ years of experience, OR Advanced degree and 3+ years of experience in any form of turbomachinery aero-mech analysis and design
Excellent problem solving & communication skills
Practical hands-on experience building & aerodynamically testing new product designs
Participation in a full product/system development cycle
High skill level in relevant CAE (FEA, CFD, engineering programming, Matlab/Simulink)
Basic 3D CAD skills

Nice To Haves

M.S. or Ph.D. in Mechanical or Aerospace Engineering (or equivalent)
Experience working with different fluids in addition to air (e.g. refrigerants, liquid coolants, cryogenics), including “2 Phase” flows
Experience working on small fast-paced independent teams

Responsibilities

Perform all the aerodynamic and mechanical analyses involved in developing turbocompressors for hydrogen fuel cell systems in support of team as we iterate through our designs
Aerodynamic for performance, mechanical for durability and reliability
Compressors and Turbines, Centrifugal/Radial & Axial, single-stage and multi-stage
Occasionally could include liquid pumps, fans/blowers and/or fluids different than air
1D & 2D Mean-line Codes and hand-calcs, 3D CFD & FEA
Using commercial software CAE tools as well as building your own tools as needed
Perform preliminary 3D CAD design work as needed to support your analyses
Collaborate with teammates who are all-around mechanical engineers to ensure that their sub-systems and components are aerodynamically optimized by providing them with the best aero-mech analysis & design support possible
Support your teammates in testing prototypes, including designing and building required testing fixtures & setups as well as instrumentation, data acquisition and reporting
Actively support testing of higher-level systems, up to and including aircraft flight testing
