Senior Embedded Software Engineer - Motor Control
Location: Long Beach, California (On-site)
Employment type: Full time
Compensation: $155,000-$221,000, plus equity and benefits
Position overview
Our client is an engineering-led technology company developing advanced embedded systems for demanding, high-reliability environments. They are seeking an experienced motor-control firmware engineer to own the embedded software for a new microcontroller-based actuation subsystem. The role spans board-support software, real-time scheduling, peripheral integration, control state machines, protection behaviour, closed-loop control algorithms and integration with power electronics. This is a hands-on individual-contributor position with end-to-end technical ownership, from early requirements and architecture through hardware bring-up, control tuning, verification, field support and continued improvement. You will work closely with embedded, electrical, power-electronics, controls and test engineers.
Responsibilities
- Own the motor-control software subsystem from initial requirements and architecture through production-ready implementation and ongoing support.
- Develop bare-metal and/or RTOS-based firmware for a microcontroller-based motor-control system.
- Create and maintain MCU board-support packages, low-level drivers and peripheral interfaces.
- Configure and debug timers, PWM generation, ADCs, interrupts, DMA, memory and communication peripherals.
- Design deterministic real-time software under strict latency, jitter, timing, memory and compute constraints.
- Develop control state machines, operating modes, fault handling, safe states and protection behaviour.
- Implement, tune and validate closed-loop motor-control algorithms.
- Integrate motor-control firmware with power electronics, sensors, communications interfaces and higher-level control systems.
- Bring up new boards in close collaboration with electrical and power-electronics engineers.
- Read schematics and component documentation, review hardware interfaces and diagnose hardware/software integration issues.
- Debug low-level problems involving control behaviour, timing, interrupts, DMA, concurrency, synchronisation, memory corruption and peripheral configuration.
- Use oscilloscopes, logic analysers, in-circuit debuggers and related laboratory tools to identify root causes.
- Develop unit, integration, software-in-the-loop and hardware-in-the-loop tests in collaboration with test engineering.
- Support laboratory and field testing, production testing, failure investigation and corrective improvements.
- Improve build automation, continuous integration, static analysis, profiling and automated testing.
- Produce concise engineering documentation, contribute to technical reviews and mentor other engineers while remaining hands-on.
Required qualifications
- Approximately five or more years of relevant embedded-software experience is preferred; demonstrated technical depth and delivery experience are more important than a specific tenure.
- Deep practical expertise in bare-metal and/or RTOS-based microcontroller development for real hardware systems.
- Strong proficiency in at least one low-level systems-programming language, such as C or C++.
- Practical experience developing firmware for motor control, motion control, power electronics or a closely related real-time control system.
- Experience implementing deterministic software under latency, jitter, timing, memory and performance constraints.
- Strong understanding of real-time scheduling, timers, interrupts, DMA, concurrency, synchronisation, memory management and peripheral control.
- Experience with control state machines, fault handling, safe-state behaviour and protection logic.
- Experience bringing up new MCU boards, reading schematics and debugging integrated hardware/software systems.
- Experience with common embedded communication protocols and bus architectures.
- Strong laboratory-debugging skills using oscilloscopes, logic analysers, in-circuit debuggers and related equipment.
- Experience writing maintainable production code, conducting code reviews, developing automated tests, using static analysis and profiling performance.
- Ability to work independently with incomplete information while collaborating closely across engineering disciplines.
- Willingness to support field testing when required.
- US. citizenship and eligibility to obtain and maintain a U.S. security clearance.
Desirable experience
- Safety-critical, mission-critical or other high-reliability embedded products
- Taking a greenfield motor-control system through design, tuning, verification and operational deployment
- Advanced commutation and closed-loop control techniques
- Current, velocity and position-control loops
- Feedback sensors, signal conditioning and estimator integration
- Inverter control, power-stage protection and fault investigation
- Experience across multiple MCU and RTOS platforms
- HOOTL, SIL, HIL or HITL test environments
- Robotics, aerospace, automotive, industrial-control, medical, energy or similarly integrated electromechanical systems
