Senior Full Stack Engineer

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.

Our full-stack engineers work within cross-functional feature squads to create the capabilities our customers leverage every day. This position will work closely with product, design, business stakeholders, and colleagues across the engineering org to bring our product roadmap to life.

What you will do and achieve:

• Create the next generation of product experience: You will build new features and expand existing capabilities across the Trunk Tools product platform, and get deeply hands-on with our core LLM-enabled agentic product experience. This isn’t yet another CRUD build! We’re creating the technology to unlock a new paradigm in how users interact with an app, that leverages the power of language models from the ground up.

• Own capabilities end-to-end: We believe in individual ownership at Trunk Tools. As a full-stack engineer on one of our feature squads, you'll drive new capabilities from concept to production — collaborating with product and design to shape what gets built, writing code across the stack, and working directly with customer success as we deploy and scale new features with real users.

• Collaborate closely with machine learning/vision engineers, LLM domain experts, and our integrations team: Our platform relies on complex integrations with third-party systems, extensive data processing capabilities, and a cutting-edge agentic layer. All of this technology comes together in our user-facing product: as you develop and deploy new capabilities, you’ll work in a highly collaborative and cross-functional way.

• Constantly improve technical reliability and ability to scale: you’ll iterate on our backend architecture to support the growing needs of thousands of users, making sure our systems are built to scale as we grow.

• Strategic participation: In this role you’ll help inform the architecture, practices, and tools you’ll use every day to shape what we build, and how.

Who you are:

• Demonstrable past experience in one or more leveraged, high-output full-stack engineering roles

• Highly proficient in TypeScript and full-stack development across backend and frontend, with experience in our technical stack (Node + Express + React)

• You have experience architecting systems, designing data schemas, and are comfortable with both relational and non-relational databases

• You have previous experience shipping products to users, and enjoy the pace of a fast-moving startup environment

• You’re energized by user impact and how high-quality engineering can be a multiplier – you care deeply about both what ships and how it’s built.
