Trunk Tools is the AI platform built for construction. One brain that reads every document on your job, and tools that transform your team’s workflows. Backed by Insight and Redpoint.
About the role
You're a platform generalist with real backend depth. You're happiest with genuine ownership and comfortable with the ambiguity of an early-stage company. This is a hands-on role first: you'll spend most of your time writing code and designing systems. You self-manage, you work across teams, and you already lean on AI coding agents to move faster. As the day-to-day of engineering shifts toward orchestration, design, and cross-team work, that's increasingly where you spend your time.
What they're looking for
- Deep, broad backend experience on complex systems. We weigh breadth and depth over exact years, but strong candidates usually have a decade or more
- Fluent in TypeScript, Python, and Go, with three or four languages on your resume. Rust or similar is a plus
- You've built robust backend services and platform infrastructure
- You've architected systems and data schemas across relational and non-relational databases
- Fluent with AI coding agents and use them daily to ship faster without dropping quality
- Startup grit: you self-manage, stay hands-on, and partner well across teams
More about this role
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 100+ employees...
