Overview

Lorien has an exciting opportunity for a Senior Firmware Engineer to join our Robotics client on a direct hire basis. This is a 100% hands-on engineering role, requiring 5+ years of production firmware experience & a strong C/C++ and motor control background. The ideal candidate will be comfortable taking firmware from prototype to production, enjoy owning design decisions, and live within a commutable distance from Austin, TX for an onsite work environment.

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
• 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)
