Anduril Industries is a defense technology company building advanced military systems powered by Lattice OS, an AI-powered operating system for real-time command and control. You will join the ArsenalOS team to build the software that powers manufacturing, supply chain, and production operations across the factory floor and broader hardware enterprise.
As a Staff Software Engineer, Frontend Platform, you will define frontend architectures, build reusable platform capabilities, and establish patterns that enable product teams to deliver high-quality web, mobile, and progressive web experiences at scale. You will work on complex production applications and the shared systems behind them—including component libraries, application frameworks, developer tooling, frontend infrastructure, and architectural patterns used across multiple teams.
Your responsibilities include:
- Architecting scalable frontend systems and patterns across large applications and multiple product teams
- Building reusable frontend infrastructure, shared libraries, component systems, and application frameworks
- Establishing best practices for browser fundamentals, application performance, testing, observability, and reliability
- Leading technically ambiguous initiatives from architecture through implementation and adoption
- Identifying common problems across teams and turning them into reusable platform capabilities and paved paths
- Influencing technical direction across teams while remaining hands-on in production code
- Collaborating with product teams to deliver intuitive, reliable, and scalable applications
You should be comfortable moving between hands-on product development and broader technical leadership, with strong software engineering fundamentals beyond the frontend, including APIs, authentication and authorization, data modeling, and distributed systems concepts.
**Requirements:**
- Deep experience building and architecting modern web applications using TypeScript, JavaScript, React, and related technologies
- Experience defining frontend architecture and scalable patterns across large applications or multiple product teams
- Experience building reusable frontend infrastructure, shared libraries, component systems, or application frameworks
- Strong understanding of browser fundamentals, application performance, testing, observability, and reliability
- Strong software engineering fundamentals beyond the frontend, including APIs, authentication and authorization, data modeling, and distributed systems concepts
- Experience leading technically ambiguous initiatives from architecture through implementation and adoption
- Ability to identify common problems across teams and turn them into reusable platform capabilities and paved paths
- Ability to influence technical direction across teams while remaining hands-on in production code
- US Citizen required (position requires access to export-controlled data)
**Preferred Qualifications:**
- Experience building frontend platforms, design systems, application frameworks, or shared developer infrastructure
- Experience with progressive web applications, mobile applications, or React Native
- Experience with offline-first, resilient, kiosk, industrial, or other operationally critical user experiences
- Experience with monorepos, shared libraries, package management, and large TypeScript codebases
- Experience with enterprise or manufacturing software such as MES, WMS, PLM, or ERP
