Sr. Motor Control Engineer

Diamond Foundry

Diamond Foundry

San Francisco, CA, USA
Posted on Thursday, February 8, 2024
Diamond Foundry Inc. is solving the thermal limitation at the foundation of today's most exciting tech industries -- AI & cloud compute, electric-car power electronics, and 5G/6G wireless. We have managed to produce the world's first single-crystal diamond wafers and are now on a mission to put a diamond behind every chip. We are the rare unicorn that has grown fast and profitably. We received $515m in funding and are executing a multi-$B expansion plan for one of the greenest forms of tech manufacturing: converting greenhouse gas into diamond wafers using zero-emission energy.
In this role your primary responsibility will be to develop high-performance control algorithms for electric systems including motor-generators, power inverters, energy storage. You will create, maintain, and effectively use simulation and embeddable models of these systems for performance evaluation. You will be expected to derive high integrity plant and control models validating these through simulation and testing. This may involve auto-coding from the derived control simulation, hand coding and coding of the hardware abstraction layer. This candidate has a strong team membership skills, and the ability to lead and support multiple simultaneous projects related to DFI’s advanced control power products implementing next-generation power application solutions. You will play a key role in a small, fast-moving team and participate in architecture, design, and implementation of motor control systems and power solutions.
This engineer will work closely with the hardware, mechanical, integration, to design, develop, test and improve system-level behaviors.

Responsibilities:

  • Manage project timelines and milestones.
  • Create high integrity simulation models of electrical components and systems.
  • Utilize models to explore parameter dependence and sensitivities to stretch the bounds of highly-efficient and powerful motor control.
  • Debug and test embedded software and systems on the bench, at the dyno and in the field.
  • Follow development cycle process including: bug / defect tracking and reporting; unit, regression, and user-acceptance testing; documentation.

Requirements:

  • BS in EE, MS preferred, with at least 5 years of industry experience with advance control of electric motor and modeling.
  • Deep knowledge of high-performance motor control algorithms and software including various formulations of field-oriented control and direct torque/flux control.
  • Experience with motor / generators, power converters, energy storage subsystems and control algorithms is required.
  • Electric motor, power system and control algorithm modeling and simulation experience (Simulink/Pspice).
  • Implementation of control algorithms for electric motors and inverters in embedded C.
  • Automotive powertrain experience(inverters).
  • 32 bit MCU platform, preferably STM32 family and code composer.
  • Experience with Digital Signal Processors required.
  • UI and graphic UI design using Python or equivalent required.
  • Hands-on debugging and logical problem-solving experience.
  • Track record of project management/delivery to internal and external groups on time with required quality.
  • Great communication skills (both oral and written) and a positive, team-oriented attitude.
  • Ability to work effectively in a dynamic small-company environment.
