Senior React Engineer, Maritime App

The Maritime App team builds the full-stack web application (part of Lattice OS) used to control all of Anduril’s Maritime products (Dive-LD, Dive-XL, Copperhead, Seabed Sentry, ASV, and more) from nodes in the cloud and laptops in the field. We bring together all the advanced tech from Anduril’s Software Platform into a hardened Maritime-focused software stack that’s shipped along with our autonomous maritime robots. We’re a full-stack web application team building a slick, modern, map-focused React frontend with a Go backend. We leverage Anduril’s proprietary mesh networking and distributed storage tech to keep Lattice working smoothly even in extreme network conditions (there’s no wifi underwater).

We’re looking for an experienced frontend/full-stack engineer to shape the future of our web app architecture and infrastructure. Lattice for Maritime is only a couple years old and has a lot of exciting capabilities to build over the coming years! You will lead us in continuously evolving our architecture and best practices to ensure your teammates can continue to build performant and reliable features efficiently. This role requires a solid foundation in web technologies, managing large React codebases, optimizing runtime and build performance, and optimizing communication with the backend.
If you're a collaborative problem-solver who finds satisfaction in creating tools that amplify the effectiveness of other engineers, we want to talk to you.

• Design and implement architectural patterns, tools, and best practices for building components, pages, services, and apps
• Proactively identify pain points and opportunities to improve our dev experience and infrastructure
• Work across the stack (front-end, back-end, build, CI/CD) to get things done
• Support and mentor fellow engineers on engineering best practices, and on how to best use our tools
• Lead the creation of net-new apps and/or break our app down into more focused experiences
• Harden our component library to work more seamlessly with our design system
• Evolve our use of libraries (e.g. for mapping, charting, logging) to increase performance, maintainability, and usefulness. And make them really really ridiculously good looking.

• Bachelor's degree in Computer Science or related field; or equivalent industry experience
• Experience building production web applications in JavaScript or TypeScript (we use TypeScript and React)
• Experience designing architectural patterns, tooling, or best practices, and leading engineering teams in adopting them
• Experience effectively integrating tools and libraries (build systems, component libraries, testing frameworks, monitoring) into frontend codebases and CI/CD pipelines
• Familiarity with modern backend programming languages such as Go, C++, or Rust.
• High empathy for your fellow engineers and users
• Minimum 5 years of software engineering experience
• Must be a U.S. Person due to required access to U.S. export controlled information or facilities

• Have a bias for action and taking ownership. You have a track record of solving a problem if you see one.
• Experience maintaining continuous integration systems (we use CircleCI)
• Experience or interest working in monorepos with modern build systems
• Experience or interest working in Go
• Experience with gRPC/protobuf or similar technologies
• Experience with NixOS
• Experience designing effective/reliable use of AI agents to augment software development teams
