About The Company

A well-funded technology company is building advanced automation and software systems for critical real-world industries.

Its products operate in live environments where software directly coordinates physical operations, including logistics, food delivery infrastructure, transportation, and autonomous systems.

The organization has substantial financial backing and a strong engineering culture. Engineers are given significant ownership over technical decisions and are expected to solve complex problems across software, operations, and physical systems.

About The Role

We are looking for a Senior Frontend Engineer to build and scale real-time applications that power live logistics and operational workflows.

You'll work primarily with React and TypeScript, building high-performance interfaces that consume continuously changing data through WebSockets, Server-Sent Events, and GraphQL subscriptions.

This is a hands-on role with ownership from architecture through production. You'll collaborate closely with backend engineers and operational teams while helping establish frontend engineering standards as the platform scales.

What You'll Do

• Design and build high-performance React applications for real-time operational workflows
• Build interfaces powered by WebSockets, SSE, and GraphQL subscriptions
• Own complex frontend projects from technical design through production rollout
• Improve frontend performance, reliability, latency, and scalability
• Build data-rich interfaces for live logistics and operational environments
• Contribute to mobile applications built with React Native
• Collaborate closely with backend engineers and operations teams
• Make architectural decisions around state management, data synchronization, and frontend infrastructure
