Senior Robotics Software Engineer, Perception

About the role

Parallel Systems is pioneering autonomous battery-electric rail vehicles designed to transform freight transportation by shifting portions of the $900 billion U.S. trucking industry onto rail. Our innovative technology offers cleaner, safer, and more efficient logistics solutions. Join our dynamic team and help shape a smarter, greener future for global freight.

Parallel Systems is seeking a Senior Robotics Software Engineer to develop the perception and sensor fusion algorithms that let our fully autonomous, battery-electric rail vehicles understand the world around them in real time. In this role, you'll design and implement geometry-based computer vision and robotics algorithms alongside ML/learned-based methods, fuse high-throughput data from lidar, camera, IMU, and GPS sensors, and validate that the resulting system runs reliably around the clock in the field. You'll work closely with ML, firmware, embedded platform, and systems engineers to take sensor selection, calibration, and real-time fusion from first principles through production deployment. If you like working close to the math, the sensors, and the real world all at once, we'd love to work with you.

Responsibilities

- Build and maintain real-time robotics software that ingests and fuses high-throughput, multi-modal sensor data from lidar, camera, IMU, GPS, and other sensors.

- Implement, validate, and test real-time sensor fusion code across simulation and real-world deployments, catching regressions before they reach the field.

- Perform sensor calibration (intrinsic, extrinsic, temporal) and apply a strong foundation in linear algebra, 3D geometry, and optimization (e.g., Kalman/particle filters, non-linear optimization) to state estimation problems.

- Design and implement geometry-based computer vision and robotics algorithms (multi-view geometry, filtering, tracking) for real-time perception; experience with ML-based approaches is a bonus.

- Evaluate sensor selection and system-level tradeoffs, and define test and validation plans that prove the system can run reliably 24/7 in production.

- Contribute to sensor system hardware design, including IP-rated, ruggedized enclosures and mounts built to hold up in real-world field conditions.

- Build and maintain sensor pipelines for real-time sensor and video data streaming and processing.

- Collaborate with ML, firmware, embedded platform, and systems engineering teams to integrate perception algorithms into the full autonomy stack.

What Success Looks Like:

- After 30 Days: You've developed a solid understanding of our current perception architecture, sensor suite (lidar, camera, IMU, GPS), and calibration and fusion pipeline. You've reviewed the state estimation and tracking algorithms end-to-end and identified concrete opportunities to improve accuracy, robustness, or performance.

- After 60 Days: You've designed and landed improvements to a sensor fusion, state estimation, or tracking algorithm, and contributed to sensor calibration procedures. You've built a proof of concept demonstrating measurable gains in accuracy or robustness.
