Senior Software Engineer, Frontend

Job Description

Job Description

At Trunk Tools, we’re the leading AI company revolutionizing construction—the second-largest industry on earth. We recently raised a $40M Series B led by Insight Partners, bringing our total funding to $70M from top-tier investors including Redpoint and Innovation Endeavors. This new round is fueling our next phase of growth as we scale AI agents across the jobsite.

Our mission is to build the future of construction through intelligent automation. Despite being a $13+ trillion industry, construction still runs largely on analog processes—we’re changing that by embedding AI directly into field operations.

Founded by builders and technologists (Stanford, MIT), our team has delivered software used by over 140,000 field professionals, impacting millions of users and contributing to $10B+ in built projects. Many of us come from the field ourselves, giving us a deep understanding of the industry’s unique challenges.

After years of building the “brain” of construction, we’re now launching production-ready AI agents—starting with intelligent document processing and Q&A, and rapidly expanding into core operational workflows. Our team has doubled in the past year, and with 65+ employees (25+ engineers), we’re scaling fast and entering a period of hypergrowth—this is a rare opportunity to join at an inflection point.

What you will do and achieve :

Build Exceptional User Interfaces : Develop intuitive, high-performance, and responsive user experiences.

Push the Boundaries of React : Lead development using React, TypeScript, and modern front-end frameworks to craft clean, maintainable, and scalable UI architectures.

Collaborate Cross-Functionally : Work closely with product managers, designers, and backend engineers to translate complex workflows into elegant, user-centered interfaces.

Implement Scalable Design Systems : Contribute to and evolve our design system, ensuring consistent styling, accessibility, and performance across all platforms.

Drive Performance & Quality : Optimize rendering, reduce bundle sizes, and ensure frontend applications meet high standards for usability, speed, and stability.

Shape the Product Vision : Actively participate in product discussions, providing frontend insights that influence design decisions, technical feasibility, and long-term maintainability.

What we’re looking for :

5+ years of professional experience building web applications with React and TypeScript.

Deep understanding of modern frontend tooling (Webpack / Vite, Storybook, ESLint, etc.).

Strong grasp of UI / UX principles, accessibility, and responsive design.

Experience integrating APIs and working closely with backend teams (Node, Python, etc.).

Familiarity with design systems, state management (Redux, Zustand, Recoil), and component-driven development.

Strong problem-solving skills and ability to balance speed with code quality.

A deep passion for best in class user experience.

Bonus : Experience in AI / ML-driven products, or working within high-growth SaaS startups.
