Job description

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.
What You'll Do:
  • Design, build, and own full-stack web applications from development through production
  • Develop backend services and APIs using Node.js (TypeScript) and Python where appropriate
  • Build responsive, high-performance frontends using React
  • Design clean, scalable APIs and data models
  • Work with large, complex datasets and optimize data flow across systems
  • Collaborate closely with product, AI, and engineering teams to deliver customer-facing features
  • Debug and resolve issues across frontend, backend, and production environments
  • Improve system performance, reliability, and developer workflows
  • Contribute to code quality through reviews, testing, and shared engineering practices

What You Bring:
  • 5-10+ years of experience building and shipping production web applications
  • Strong proficiency in TypeScript, JavaScript, Node.js, and React
  • Experience designing and building full-stack systems (APIs, services, frontend)
  • Solid understanding of system design, scalability, and performance tradeoffs
  • Experience working with databases such as MongoDB, Redis, or similar
  • Experience deploying and operating applications in AWS or similar cloud environments
  • Strong problem-solving skills and ability to work across the stack
  • Effective communication and collaboration skills in cross-functional environments

What Sets You Apart:
  • Experience building data-heavy or real-time web applications
  • Experience integrating with external APIs and third-party platforms
  • Familiarity with monorepo architectures (Nx, Lerna)
  • Experience building and scaling production applications used by external customers
  • Experience improving performance, reliability, and developer workflows in web systems

$155,000 - $200,000 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 statu
We may use artificial intelligence (AI) tools to support parts of the hiring process, such as reviewing applications, analyzing resumes, or assessing responses. These tools assist our recruitment team but do not replace human judgment. Final hiring decisions are ultimately made by humans.
