FieldAI's Irvine team is where embodied AI meets real robots, real sensors, and real field deployments. Based in the heart of Southern California's robotics ecosystem, we build risk-aware, reliable, field-ready AI systems that solve the hardest problems in robotics and unlock the full potential of embodied intelligence. If you want your work to ship, get tested on hardware, and improve through real deployments, Irvine is the place. We go beyond typical data-driven approaches or pure transformer-only architectures, combining rigorous engineering with learning systems proven in globally deployed solutions that deliver results today and get better every time our robots run in the field.

About the Role

We''re looking for a Perception Engineer to help build the 3D scene and traversability representations our robots rely on to navigate real-world environments. You''ll design learning-based approaches to spatial understanding from point cloud-based representations to learned traversability mapping and take them from research prototype to production on physical robots. This role sits at the intersection of perception, mapping, and autonomy, working closely with cross-functional teams to make sure our systems perform reliably in the field, not just in simulation.

What You Will Get To Do

1. Own 3D Representation for Navigation (core focus)

• Design and build the 3D scene/traversability representations our robots plan and act on - point cloud-based or learned implicit structures - optimized for real-time, on-robot use rather than offline reconstruction quality.
• Drive a long-term research agenda on learning-based approaches to building these representations - learned traversability, learned surface/reconstruction, geometry-aware embeddings - rather than only integrating existing classical pipelines.
• Stay close to the current literature on 3D scene representation for navigation - online navigation-mesh construction from streaming point clouds, learned elevation/traversability mapping, topologically-grounded navigation representations - and translate promising ideas into deployable systems.

2. Build and Maintain Perception Systems

• Design, implement, and maintain perception systems for autonomous robots operating in real-world environments.
• Develop localization and mapping capabilities that hold up in unstructured, off-road, and field conditions.
• Continuously evaluate and improve perception performance through testing, iteration, and field validation.

3. Develop and Integrate Sensor-Based Perception

• Implement perception algorithms that fuse data from multiple sensors - LiDAR, cameras, RADAR, inertial sensors.
• Support integration of new sensing modalities and configurations as platforms evolve.
• Ensure perception software behaves consistently across simulation and real-world deployment.

4. Deploy Perception Software on Real Robots

• Take representations and algorithms from research prototype to production on physical robots.
• Debug issues discovered during on-robot testing and field operations.
• Collaborate with autonomy, controls, and platform teams to integrate cleanly into the full autonomy stack.

5. Improve System Robustness and Scalability

• Contribute to code quality, testing, and long-term maintainability.
• Build tools, metrics, and regression tests for representation quality and downstream navigation performance.
• Help scale representation and perception solutions across multiple robots, environments, and missions.

6. Collaborate Across Teams

• Work with engineers, researchers, and field operators to define representation and perception requirements.
• Communicate technical tradeoffs clearly to both technical and non-technical stakeholders.
• Support field operations and customer demonstrations by keeping systems production-ready.

What You Have

• Bachelor's or Master's degree in Robotics, Electrical Engineering, Computer Engineering, Computer Science, Mechanical Engineering, or a related technical field.

• 3+ years of experience in verification, validation, systems test, or perception evaluation for robotics, autonomous systems, automotive, or similar domains.

• Experience working with robotic sensors such as LiDAR, cameras, GPS, and IMUs.

• Strong understanding of perception system behavior, sensor limitations, and common failure modes.

• Experience developing test plans, validation procedures, performance metrics, and structured test reports.

• Experience analyzing logs, datasets, and field results to debug issues and perform root-cause analysis.

• Strong cross-functional communication skills and the ability to work effectively with development teams while representing an independent V&V function.

What Sets You Apart

• Experience validating perception systems for autonomous vehicles, mobile robots, drones, industrial robots, or defense robotics platforms.

• Familiarity with perception workflows such as detection, tracking, localization, mapping, or sensor fusion.

• Experience with simulation, software-in-the-loop, hardware-in-the-loop, and replay-based validation.

• Experience with sensor calibration, synchronization, time alignment, and sensor health monitoring.

• Experience building automated regression tools or validation infrastructure.

• Familiarity with annotated datasets, ground-truth generation, and scenario-based test design.

• Knowledge of structured verification processes, requirements traceability, and safety-oriented development practices.

$135,000 - $190,000 a year

Our salary range is generous and we consider each individual's background and experience when determining final compensation. Base pay may vary based on role scope, job-related knowledge, skills, experience, and the Irvine, California market.

Why Join FieldAI in Irvine?

In Irvine, you will work where the robots are. Our local team builds and tests systems on real hardware with real sensors, then ships them to operate in unstructured, previously unknown environments around the world. We are solving one of robotics' hardest challenges: reliable deployment outside the lab. Our Field Foundational Models raise the bar for perception, planning, localization, and manipulation, with an emphasis on explainability and safety for real-world use.

You will collaborate with a world-class team that thrives on creativity, resilience, and bold thinking. We bring deep experience from organizations such as DeepMind, NASA JPL, Boston Dynamics, NVIDIA, Amazon, Tesla Autopilot, Cruise, Zoox, Toyota Research Institute, and SpaceX, along with a track record of field deployments and strong performance in DARPA challenge segments.

Be Part of the Next Robotics Revolution

We are looking for builders who want their work to leave the whiteboard and show up on robots. If you enjoy tackling tough, uncharted questions and working across disciplines, you will find your people here. Our teams span AI, software, robotics engineering, product, field deployment, and technical communication, all focused on shipping systems that perform in the real world.

Our headquarters is in Irvine, and we partner closely with teams there as well as colleagues across the US and around the world. Join us in Southern California and help define what dependable, field-ready autonomy looks like.

We value diverse perspectives and are committed to fostering an inclusive workplace. We evaluate candidates and employees based on merit, qualifications, and performance, and we do not discriminate on the basis of race, color, gender, national origin, ethnicity, veteran status, disability status, age, sexual orientation, gender identity, marital status, or any other legally protected status.

We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses and identifying potential inconsistencies or verification signals in application materials based on available information. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
