Sr. ROS Software Developer

Job Title: Sr. ROS Software Developer

Location: Sunnyvale, CA [Onsite]

Duration: 12+ months

Position Summary

Job Description:

We are seeking a Senior Software Engineer contractor to develop robotics platform software on NVIDIA Jetson (Linux/ROS2) for a manipulation system integrating custom grippers, sensors, and actuator subsystems. You will write ROS2 nodes, develop host-side SDKs interfacing with embedded hardware over Ethernet and EtherCAT, integrate sensor pipelines (cameras, depth, tactile, IMU), and deploy perception/control algorithms into the real-time platform. The work is hands-on, systems-level C++/Python on Ubuntu with PREEMPT_RT, JetPack, and Docker.

Key Responsibilities-

Develop and maintain ROS2 nodes for gripper command/state, sensor streaming (cameras, IMU, dToF, tactile), and device management (DFU, discovery, calibration)

Develop and integrate host-side SDKs that interface with embedded MCU subsystems over Ethernet and EtherCAT — wrapping vendor C/C++ libraries into ROS2-compatible drivers

Implement sensor integration pipelines on Jetson: camera frame acquisition and GPU-accelerated processing (CUDA de-Bayering), depth sensor post-processing (dToF zone → point cloud), IMU streaming, tactile data decoding

Integrate control and perception algorithms developed by scientists into the real-time platform — ensuring timing, data flow, and API contracts are met

Develop device management software: firmware update orchestration (DFU) across heterogeneous nodes (MCU, sensor modules, actuators), device discovery, health monitoring

Write and maintain integration tests validating end-to-end data paths from embedded hardware through ROS2 topics

Required Qualifications-

5+ years of software engineering experience, with significant work on embedded Linux / robotics platforms

Strong proficiency in C++ and Python on Linux (Ubuntu)

Hands-on experience with ROS2 — writing nodes, custom message types, lifecycle management, launch files, parameter handling

Experience developing software on NVIDIA Jetson platforms (JetPack, CUDA basics, Docker containers)

Experience interfacing host software with embedded systems — consuming C/C++ SDKs from hardware vendors, Ethernet/UDP communication with MCUs, serial protocols

Experience with sensor integration: cameras (V4L2, GStreamer, or vendor SDK), IMUs, depth sensors, or similar

Comfortable working at the hardware-software boundary — reading protocol specs, validating data with Wireshark/logic analyzers, coordinating with firmware engineers

Experience with EtherCAT master libraries (IgH, SOEM) on Linux for real-time motor/actuator control

Preferred Qualifications-

Experience with CUDA kernels or GPU-accelerated image processing (de-Bayering, filtering, point cloud generation)

Experience with CycloneDDS or other DDS implementations and real-time ROS2 tuning (executor configuration, QoS, zero-copy transport)

Experience integrating manipulation/control algorithms (trajectory execution, position control loops, impedance control)

Familiarity with Cyphal/DroneCAN or other CAN-based protocols from the host side

Experience with Docker-based development and deployment workflows on embedded Linux

Experience with device firmware update orchestration across multiple heterogeneous targets

Familiarity with PREEMPT_RT Linux configuration, CPU isolation, and real-time scheduling

Experience with Yocto/OE or custom BSP builds for Jetson

Experience with calibration systems (camera intrinsics/extrinsics, hand-eye calibration)

This position is for one of the big technology giant.
