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

• Mentor other engineers and contribute to frontend engineering standards

• Help scale the frontend platform as the company's operations expand

What We're Looking For

• 3+ years of professional software engineering experience

• Strong production experience with React and TypeScript

• Experience building complex, high-performance frontend applications

• Experience working with real-time systems , such as:

  • WebSockets

  • Server-Sent Events

  • GraphQL subscriptions

  • Live state synchronization

• Strong understanding of frontend architecture and performance optimization

• Ability to lead technical design from an initial problem through production

• Understanding of backend systems and APIs

• Strong ownership and ability to work independently

• Willingness to work on-site in New York City five days per week

Preferred Qualifications

• React Native or other mobile development experience

• Experience with logistics, transportation, delivery, marketplaces, or operational software

• Experience building mapping, dispatch, fleet, inventory, or real-time tracking interfaces

• Experience working on high-throughput consumer or operational platforms

• Strong system-design experience

• Experience mentoring engineers or leading technical projects

Strong Backgrounds Include

Candidates from companies working on:

• Food delivery and logistics

• Marketplaces

• Fleet and transportation

• Real-time operations

• Supply chain

• Mapping and location-based products

• High-scale consumer applications

Experience at companies such as delivery marketplaces, logistics platforms, transportation technology companies, or other high-growth technology organizations is particularly relevant.

What We're Not Looking For

• Frontend engineers who have only worked on static CRUD applications

• Candidates without meaningful real-time application experience

• Engineers without production React/TypeScript experience

• Candidates focused exclusively on design systems or internal tooling

• Candidates unwilling to work on-site in New York City

Interview Process

1. Recruiter screen

2. Frontend technical interview
