Senior​/Principal Motor Control Engineer

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, and energy storage. You will create, maintain, and effectively use simulation and embeddable models of these systems for performance evaluation. Development will involve auto‑coding from the derived control simulation, hand‑coding, and coding of the hardware abstraction layer. You will 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 the architecture, design, and implementation of motor control systems and power solutions.

This engineer will work closely with the hardware, mechanical, and integration teams to design, develop, test, and improve system‑level behaviors.

This position will be a temp‑to‑hire position.

• 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.

• BS in EE, MS preferred, with at least 5 years of industry experience with advanced 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 STM
  32 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.

Salary: $70,000 – $180,000 a year. Position is eligible for company shares. Actual compensation may be higher or lower in the range based on various factors, including, but not limited to, a candidate’s job duties, experience, and expertise. We will also consider higher‑level candidates and salary will be adjusted accordingly.
