Staff Software Engineer - Controls

• Control-Critical Embedded Software: Design, implement, and maintain real-time embedded C++ software that executes control loops for VTOL and gimbal systems, with a focus on deterministic performance, timing, and robustness in production environments.
• Applied Flight Controls (VTOL): Implement and tune flight control behaviors—including attitude, position, and transition modes—directly in firmware for multirotor and VTOL platforms, translating system dynamics into reliable, testable software.
• Modern C++ for Firmware: Define and uphold modern C++ best practices for embedded and real-time systems, including memory safety, concurrency models, unit testing, and CI workflows appropriate for control-critical codebases.
• Systems Integration & Collaboration: Work closely with mechanical, electrical, and hardware teams to define clean software–hardware interfaces, integrate sensors and actuators, and support bring-up, HIL testing, and performance iteration.
• Verification & Validation Infrastructure: Build and maintain software-in-the-loop (SIL) and hardware-in-the-loop (HIL) test benches; analyze telemetry and performance data to guide tuning, debugging, and system-level improvements.
• Gimbal Firmware & Controls Integration: Contribute to gimbal product development by implementing motor control logic, sensor fusion interfaces, and low-level firmware that enables stable, high-bandwidth motion control.
• Technical Ownership: Drive critical control-adjacent software from design through deployment, balancing performance, safety, and maintainability across the embedded stack.
• Other duties as assigned.

• Control Systems Expertise: 5+ years designing and implementing control algorithms for gimbals, stabilizers, or aerial vehicles.
• Embedded Robotics Background: Proven experience shipping embedded robotics products in C++ on microcontrollers (ARM Cortex-M, STM32, etc.).
• Strong C++ Skills: Deep understanding of modern C++ (14/17/20), real-time constraints, memory management, and synchronization primitives.
• Geometry & Transformations: Solid grasp of 3D kinematics, coordinate frames, quaternions, and homogeneous transforms.
• Frame-Level Expertise: Experience in one or more of attitude control, sensor fusion, target tracking or other complex frame-transformation problems, perception, and related system performance metrics.
• Sensor Integration Expertise: Hands-on experience integrating feedback sensors, such as IMUs, encoders, and related sensing hardware, into drive-system control loops.

• PX4 Flight Stack: Hands-on with PX4 middleware, MAVLink, and QGroundControl integration.
• Simulation & URDF: Experience working with URDF-based modeling and robotics simulation environments.
• Hardware Debugging: Proficient with oscilloscope, logic analyzer, and hardware debugging tools.
• RTOS Proficiency: Experience with FreeRTOS, Zephyr, or similar real-time operating systems.

• This role requires hands-on engagement with physical hardware and electronics systems.
• The individual must be able to perform direct electronics debugging, including working with exposed circuitry, connectors, and embedded systems.
• Tasks may involve assembling and disassembling hardware, probing signals, connecting test equipment, and troubleshooting electrical and mechanical components.
• The role may also require extended periods of bench work, handling small components, and operating development and diagnostic tools in laboratory or field environments.
