The Opportunity

At Lumber, you’re not just pushing pixels—you’re shaping how thousands of construction teams experience technology in the field and on the jobsite. This is a chance to build UI that doesn’t just look good, but actively solves real-world problems for workers who don’t have time for clunky apps or slow interfaces. You’ll join a high-ownership, fast-moving engineering team where your decisions directly influence product direction and user experience. This role gives you the chance to design and ship polished, high-performance interfaces end-to-end, while working closely with product and design to solve real-world problems at scale.

What You’ll Do

Develop, optimize, and maintain highly interactive, user-friendly web applications.
Collaborate with product designers and backend engineers to translate UI/UX wireframes into responsive, high-quality code.
Own features end-to-end: from technical design, development, testing, deployment, and monitoring.
Ensure performance, scalability, and cross-browser/device compatibility of applications.
Write clean, maintainable, and reusable code following best practices.
Contribute to design discussions and architectural decisions for frontend solutions.
Debug, troubleshoot, and resolve production issues in a timely manner.
Stay updated with the latest trends and advancements in frontend technologies.

What We’re Looking For

Core Expertise:
- Strong proficiency in JavaScript, Typescript, ES6+ and React.js, React native (with hooks, context, state management like Redux/Zustand, etc.).
- Solid understanding of HTML5, CSS3, and modern frontend tooling (Webpack, Babel, Vite).
- Hands-on experience with UI frameworks/libraries (Material UI, Tailwind CSS, Chakra UI, etc.).
Familiarity with RESTful APIs, GraphQL, and integration with backend services.
Understanding of software development best practices, Git workflows, and CI/CD pipelines.
Excellent problem-solving, analytical, and communication skills.
Ability to thrive in a fast-paced, high-ownership, collaborative environment
