Description du poste

Your mission

Some key points for the position we would need

• C++

Memory management

• multithreading (executors , callback groups; prefer lock-free where sensible)
• error / exception handling (contracts , retries, watchdogs)
• ROS 2
• evaluation and use of different middlewares (CycloneDDS , Fast DDS, Connext)
• knowledge of data transfer and callback prioritization (QoS, executors , deadlines, liveliness , intra-process)
• Knowledge of other robotics frameworks (ROS 1, DDS native or custom solution , GStreamer , LCM / LCMS, ZeroMQ , etc.)
• NVIDIA Jetson
• memory management (CPU / GPU, pinned memory, zero-copy)
• HW accelerators (CUDA / TensorRT / VPI — orchestrating data flows)
• sensor acquisition interfaces (CSI / MIPI, USB3, Ethernet, CAN, SPI)

Your mission will be several parts of

• Design, build, and harden the ROS 2 middleware layer : message schemas, QoS profiles, routing, callback prioritization, dedicated executors by criticality.
• Make data move reliably from sensors → fusion / perception → planning / actuation : time sync (PTP / NTP), timestamps, clean frames / TF, rosbag replay for debugging.
• Realize a modular and extensible sensor I/O & fusion framework : drivers / bridges, message conversions, composable pipelines.
• Integrate hardware components on Jetson / ARM : bring-up GNSS / IMU / cameras / LiDAR / radar, tune I/O buses (CSI / USB / Ethernet), manage power / thermals.
• Liaise with computer vision and acoustics experts : expose stable interfaces, define latency budgets, and service contracts (topics, rates, QoS).
• Evaluate and select middleware options (DDS, transports, codecs, HW acceleration) under latency and reliability constraints.
• Keep track of the ROS 2 / middleware ecosystem & best practices (executors, tracing, security, observability), and drive continuous improvements.
• Ensure consistently high quality of the overall detection & tracking pipeline : via end-to-end integration tests, embedded CI/CD, metrics, and alerting.

What you'll work with

• ROS 2 (rclcpp, lifecycle, rosbag2, tracing), DDS (QoS profiles), C++17/20
• Jetson Orin / Xavier, CUDA / TensorRT, V4L2 / GStreamer
• Embedded Linux, colcon, Docker / Podman, Git (PRs / reviews), CI/CD

Nice to have

• RT-preempt, cgroups / CPU pinning, DDS Security, GMSL / MIPI bring-up, CAN / UDP custom protocols
• Exposure to PX4 / ArduPilot / MAVLink for autopilot interfacing (optional)

Your profile

• University degree in Computer Science, Informatics, Math, Physics, etc.
• Relevant experience with C++

Interesting frameworks are for example: EIgen, Ceres, GTSAM

• Rust is a bonus
• Also great to have ROS(2), OpenCV
• Intrinsic motivation, willing to go the extra mile, attention to detail
• Outside of the box creativity, conceptional & systematic design thinking
• Fluent in English or German
• Nationality of a NATO member nation or close ally is a must
• Successful candidates will be required to obtain security clearance
