What You Deliver:

- Design and build front-end features across our customer authoring platform and operator HMI, plus the endpoints that support them.
- Ship safely behind feature flags and entitlement gates.
- Develop new features, write automated tests, and fix bugs.
- Build reusable components for future use, optimized for maximum performance across the full lifecycle of a workflow.
- Stay updated with emerging trends and technologies, applying them to enhance operations and activities.

## Who You Are

- Bachelor's degree in Computer Science or a related field, or equivalent experience.
- 1–6 years experience contributing to production applications.
- Strong React and TypeScript experience; comfortable working in a shared component library / monorepo codebase.
- Experience contributing to Node.js and/or C# back-end services and relational database solutions.
- Proficient in development lifecycles using Git, CI/CD pipelines, and container deployments in a cloud environment (Docker, Kubernetes, AWS).
- Bonus: data visualization or 3D graphics (three.js/WebGL), state management at scale, accessibility, or industrial/HMI interface experience.

Team Player:

- Startup Energizer: The idea of joining a growing venture-backed startup excites you because you know your work will have an immediate and significant impact.
- Collaboration Champion: You thrive in a collaborative environment, working closely with others to achieve common goals and drive success.

## About Path Robotics

## Company Overview
- **One-liner**: Path Robotics builds physical AI systems that enable autonomous robotic welding for heavy industries, addressing the critical skilled labor shortage in manufacturing.
- **Entity Type**: Private (Series D, $271M total funding)
- **Headquarters**: Columbus, Ohio, United States
- **Founded**: 2014
- **Founders**: Andy Lonsberry (CEO) and Alex Lonsberry (CTO)

## Core Business
- **Primary industry**: Industrial robotics, AI-powered manufacturing automation, heavy fabrication
- **Target customers**: B2B, Enterprise — specifically heavy industry, defense, utility & energy, data center construction, and general manufacturing
- **Mission**: Create real value for customers while rebuilding the backbone of American industry by helping manufacturers navigate the skilled labor shortage.

## Products & Services
