Responsibilities
Own the perception architecture from raw sensor data to actionable inputs for planning and control
Define technical direction, architecture trade-offs, and long-term perception roadmap
Lead perception-related design reviews, root-cause analysis, and performance optimization
Lead integration, calibration, and validation of LiDAR, cameras (stereo/depth), IMU, wheel encoders, GPS, force/torque, and proximity sensors
Design and implement robust sensor fusion pipelines using filters, factor graphs, or optimization-based methods
Ensure proper time synchronization, frame alignment (TF), and data integrity across sensors
Select sensors based on environmental constraints (dust, vibration, lighting, outdoor/industrial conditions)
Develop and optimize object detection, semantic segmentation, and 3D perception algorithms
Implement obstacle detection, terrain analysis, and scene understanding for construction environments
Work with both classical computer vision techniques and modern deep learning approaches
Optimize perception pipelines for real-time performance on embedded compute platforms
Design and implement localization systems for long-duration, real-world operation
Work with LiDAR-based SLAM, visual-inertial SLAM, and hybrid approaches
Integrate with frameworks such as Cartographer, LIO-SAM, Isaac ROS SLAM, or custom pipelines
Establish quantitative metrics for accuracy, robustness, drift, and recovery behavior
Architect and maintain perception components within a ROS2-based autonomy stack
Design node architectures, lifecycle management, diagnostics, and logging for perception systems
Optimize ROS2 performance for real-time constraints on embedded platforms
Manage TF trees, message interfaces, QoS policies, and system observability
Select and justify appropriate compute platforms (embedded CPUs, GPUs, accelerators) for perception workloads
Balance performance, power, thermal, cost, and reliability constraints
Optimize pipelines for CPU/GPU usage, memory, and real-time performance
Work with hardware teams on bring-up, drivers, and system-level optimization
Qualification
Required
6+ years of experience in robotics perception, computer vision, and sensor integration
Expert-level proficiency in C, C++, and Python for production robotics systems
Strong experience with ROS2 in real-world deployments
Proficiency with Git for version control and collaborative development
Working knowledge of Docker for reproducible builds, deployment, and CI pipelines
Deep experience with sensor fusion & filtering (EKF, UKF, factor graphs)
Deep experience with SLAM & localization
Deep experience with LiDAR-based perception and 3D point cloud processing
Deep experience with camera-based perception (object detection, segmentation)
Strong understanding of coordinate frames and transformations
Strong understanding of sensor calibration (intrinsic and extrinsic)
Strong understanding of real-time and embedded system constraints
Proven track record of delivering perception systems on physical robots, not only in simulation
Experience leading perception architecture for a commercial robotics product
Ready to roll up the sleeves and join an early stage startup environment
Benefits
Competitive equity, depending on experience and role level.
The total compensation package may also include additional components/benefits depending on the specific role.
