Product Designer

About Trunk Tools

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.

About the Role

We’re looking for a Mid-Level Product Designer to help us design intuitive, impactful, and elegant solutions for the construction industry. In this role, you’ll collaborate closely with product managers, engineers, and end users to translate complex workflows into simple, delightful experiences. You will play a key part in visual design, interaction and microinteraction design, refining existing features, developing new ones, and contributing to the evolution of our product as we grow our successful startup to fully enterprise scale.

You’ll Excel in This Role if You:

• Have solid experience in product design (typically 2-4 years) and are eager to take ownership of your projects while working under the guidance of a senior designer and product leads.
• Have very strong visual design skills
• Are comfortable tackling ambiguous problems and working toward clean, user-focused solutions—either independently or in collaboration with teammates.
• Think holistically about user flows, edge cases, and how UI elements connect to backend systems (experience with design systems is a plus).
• Enjoy collaborating cross-functionally with engineers and product managers to define and ship features that solve real user problems.
• Are comfortable iterating on designs based on user feedback and are always looking to improve the product’s usability and impact.
• Are eager to participate in user research, usability testing, and customer interviews to inform your design decisions.
• Are detail-oriented and take pride in creating designs that balance functionality with visual clarity.
• Thrive in a fast-paced, evolving start-up environment and are willing to roll up your sleeves to get things done.

What You’ll Do

• Design and iterate on core product features 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:

• Experience designing for B2B and SaaS technology products
• Experience with “vibecoding” prototypes using tools like Cursor or Lovable or Figma Make
• Familiarity with the construction industry and its day-to-day workflows
• Experience working in start-ups or on lean product teams.

What we offer

• A close-knit and collaborative early-stage startup environment where every voice is heard and every opinion matters
