We are seeking a Robotics & Autonomy Engineer to develop, integrate, and maintain autonomy capabilities on UAV platforms built around the PX4 and ArduPilot stacks. This is a full-time role on our engineering team, working across a range of client projects - so the day-to-day emphasizes hands-on integration, debugging, and real-world flight validation more than ground-up design ownership. You'll work across the full UAV stack, from embedded flight software and state estimation through mission logic and system integration, with a strong focus on reliability and practical field performance.

This position suits someone who enjoys both software development and hands-on hardware work, and who's comfortable owning problems across shifting project contexts. The ideal candidate brings solid robotics and autonomy fundamentals - estimation, controls, and coordinate frames - and is eager to grow deep expertise in the PX4 autopilot stack, including VIO, map matching, and GPS-denied navigation.

MUST HAVE PERMANENT RESIDENCE IN US
Responsibilities

• Develop and modify PX4 or ArduPilot firmware to support new autonomy features and system capabilities
• Implement mission logic, flight behaviors, and MAVLink integrations
• Integrate sensors, cameras, radios, and payloads into UAV platforms
• Tune and analyze estimation and control performance (EKF/Kalman filtering, PID loops) across platforms
• Conduct flight testing and validate autonomous behaviors in real-world conditions
• Analyze flight logs and telemetry to diagnose and resolve issues
• Debug problems across the UAV stack including firmware, networking, hardware, and companion computers
• Collaborate with engineers to design robust UAV architectures and workflows
• Document system behavior, debugging results, and design decisions

Required Qualifications

• Strong robotics/autonomy fundamentals: coordinate frame transformations, state estimation (Kalman filtering / sensor fusion), and PID control analysis
• Strong C++ or C programming skills
• Experience with PX4 or ArduPilot - or demonstrated ability to ramp quickly on a complex embedded autopilot codebase
• Experience flying and testing UAV or robotic platforms
• Familiarity with MAVLink, flight logs, and autopilot configuration
• Experience debugging complex software and hardware interactions
• Ability to work independently and take ownership of engineering tasks across multiple projects
• Strong problem-solving skills and practical engineering judgment

Preferred Qualifications

• Experience with ROS/ROS 2 and Nav2
• Experience with visual-inertial odometry (VIO), map matching, or GPS-denied navigation
• Experience building or configuring drones from components
• Familiarity with companion computers (Linux), MAVSDK, or ROS
• Experience integrating sensors such as LiDAR, cameras, or GPS systems
• Experience with embedded systems or hardware debugging
• Experience analyzing flight logs and tuning flight controllers
• Personal robotics, UAV, or embedded systems projects

What We Value

• Engineers who build and experiment outside of work
• Strong ownership and accountability for outcomes
• Practical, hands-on problem solving
• Clear communication and collaboration within small teams
• Curiosity and continuous learning
