Firmware Engineer

Location: Onsite in Austin, TX

Pay: $130,000-$170,000, depends on experience level

Type: Full time, Direct Hire

Overview: Lorien has an exciting opportunity for a Senior Firmware Engineer to join an established firmware team at our Robotics client on a direct hire basis. We're looking for a hands-on embedded engineer with 5+ years of production firmware experience & a strong C/C++ and motor control background, ideally brushless motors, real-time control & field-oriented control (FOC). You'll be comfortable taking firmware from prototype to production, and you'll want a voice in code, design & architecture decisions.

Job Duties: Build, deploy & maintain motor control firmware for robotic actuators, including field-oriented control (FOC) and real-time current & torque control for BLDC & other brushless motors Own system identification, plant modeling, controller tuning & hard real-time performance for production actuators, keeping results consistent across units, temperature & load Design & implement fault detection, fault injection & recovery mechanisms for safety-critical motor control systems Help define & run the Hardware-in-the-Loop (HIL) & Software-in-the-Loop (SIL) test strategy to validate performance, safety & reliability at scale Help drive firmware quality, reliability & field performance as the product scales from prototypes to large production fleets, including telemetry, diagnostics & root-cause analysis of field failures Collaborate with controls, systems, electrical, mechanical & software engineers to architect next-generation actuators and bring hardware from prototype through production Participate in code reviews, design reviews & pair debugging, and help shape tooling, process & architecture decisions as the team & product scale

Qualifications: Bachelor's degree in Electrical, Computer or Mechanical Engineering (or equivalent experience); Master's in controls or motor drives especially valued 5+ years of production-grade embedded software experience, from concept through deployment Proficiency in C/C++, with working knowledge of Python, Docker & Git Motor control firmware experience for BLDC or other brushless motors, including FOC, current control & torque control Hands-on hard real-time embedded firmware experience in production Experience deploying firmware to field devices, with exposure to telemetry, diagnostics & reliability EtherCAT experience for real-time motor control communications Strong hardware debugging skills (oscilloscopes, logic analyzers) Able to read electrical schematics (Altium Designer preferred) & hardware datasheets Embedded communication protocols (SPI, UART, RS485, CAN) Strong collaboration & communication skills, with a desire to grow into technical leadership Experience in advanced robotics (including legged or human-form platforms), industrial robotics or other high-performance servo applications is preferred Classical & modern control theory, with hands-on system identification & controller tuning for production motor drives (preferred) Experience in advanced robotics (including legged or human-form platforms), industrial robotics or other high-performance servo applications is preferred Classical & modern control theory, with hands-on system identification & controller tuning for production motor drives (preferred) C/C++ on TI C2000 microcontrollers, with familiarity with safety-critical standards (MISRA C, ISO 26262) is preferred Model-based design tools (e.g., MATLAB/Simulink) for control design & code generation, plus contributions to firmware tooling, build systems or developer infrastructure (preferred) Encoder & current sensing front ends and gate driver ICs like DRV8353 (preferred) Impellam Group and its brands are equal-opportunity employers committed to diversity and inclusion.
