Senior Product Designer

Salary: $170K - $200K Location Type: Remote Employment Type: Full-Time

Company Overview

At Trunk Tools, we are 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.

About the Role

We’re looking for a seasoned Senior Product Designer to help shape the future of AI-driven construction software. You’ll join a small, fast-moving product team working at the intersection of real-world construction workflows, AI/ML, and next-gen UX/UI design. If you thrive designing elegant systems for complex operational problems, we want to hear from you.

You’ll Excel in this Role if You:

• Have deep experience designing for complex real-world workflows, especially those involving physical coordination, compliance, or document-heavy processes (think construction, logistics, or finance).
• Are comfortable working with ambiguous requirements and iterating fast with PMs, engineers, and subject matter experts.
• Know how to translate gnarly process logic into beautiful, usable interfaces that make users feel empowered, not overwhelmed.
• Bring strong systems thinking to your work: you know when to create one-offs and when to create reusable, scalable patterns.
• Can confidently collaborate with engineers, and have hands-on experience implementing designs with HTML, CSS, and modern frameworks. (Bonus: you’ve experimented with LLM/AI-powered interfaces and can “vibecode” a polished demo prototype when needed).
• Have helped shape and maintain design systems and component libraries that scale across teams and features.
• Understand the stakes of enterprise product design; whether you're working on Submittal workflows, RFI research tools, or a better way to display and interact with a complex knowledge graph, you're always aware of what the end-user is trying to do in the real world.

What You’ll Do

• Design and iterate on core product features and (micro)interactions from initial concepts and wireframes to high-fidelity designs and handoff.
• Collaborate with engineers to ensure accurate implementation of designs.
• Engage in user feedback loops to validate designs and adjust based on real-world use.
• Support the evolution of our product to a robust, enterprise-scale platform.
• Work closely with the Senior Product Designer, Product Managers, and the broader team to help shape the product roadmap.

Extra Credit For:

• Construction/Contech Experience: Maybe you’ve worked with BIM, construction project management tools like Procore or ACC, or have a background designing for field-first industries.
• Portfolio: A portfolio that shows clarity of thought, strong visual polish, and a demonstrated ability to reduce complexity through structure, not simplification.
• Familiarity with Tools: Tools like Lovable, Cursor, Claude/ChatGPT, Storybook, and GitHub.
• Willingness to Push: A willingness to push into early product territory: wireframing f...
