Description

About the Team DoorDash Labs is an independent team within DoorDash. We explore robotics and automation to transform last mile logistics in the long term. If you have a passion for applying robotics solutions in a service used by millions of people, we want to talk to you! About the Role In this role, your main focus will be to design and test control algorithms for Permanent Magnet Synchronous Motors (PMSM) using model-based design methodology and integrate with the rest of the powertrain system of the delivery robot. Additionally, you will rigorously test the powertrain’s performance at various levels (component testing on dyno, simulation, end-to-end road testing etc.) and continuously seek to improve development processes, testing methods, bug triage and robot performance. You’re excited about this opportunity because you will… Design and implement field-oriented control (FOC) of PMSM and low-level diagnostics algorithms using MATLAB and Simulink Tune control algorithms to optimize powertrain performance using closed-loop simulation, dyno testing and robot-level testing Build infrastructure (plant models, functional models) to systematically verify the behavior of control laws and algorithms using Simulink Test Proactively design features/systems/processes to exceed the needs of internal customers i.e. robot operations, field service, autonomy software stack and hardware Define and solve new problems not listed here using new skills and knowledge that you may have to acquire on the fly! What we’re looking for… BS/MS degree in Power Electronics, Electrical, Mechatronics, Mechanical Engineering or related technical field 3+ years of experience in developing and testing of controls algorithms for PMSM 3+ years hands-on experience of building automotive, aerospace, autonomous vehicles or other complex mechatronics systems Excellent understanding of power electronics circuits for motor controls, including gate drivers and inverters Understands basic electronics and able to read and review board schematics Proficiency in using lab instruments for debugging motor controls issues Proficiency in model-based design using MATLAB/Simulink/Stateflow and strong understanding of fundamental parts of robotics or mechatronics systems: feedback control, sensors, actuators, embedded controllers, CAN communication Working knowledge of C and auto-code generation using Embedded Coder Experience using source control and build automation tools like Git, jenkins etc. Nice to have... Working knowledge of C++/Python Experience in building physical models of mechatronic systems for simulation Experience using TI DRV8x gate driver chips Experience in sensorless estimation algorithmsStrong understanding of electric powertrain and road vehicle dynamics Deep respect and understanding for a principled and rigorous approach to testing safety-critical systems Ability to write clear, concise and complete documentation of designs and tasks Compensation The successful candidate’s starting pay will fall within the pay range listed below and is determined based on job-related factors including, but not limited to, skills, experience, qualifications, work location, and market conditions. Base salary is localized according to an employee’s work location. Ranges are market-dependent and may be modified in the future.
