About the Role

Trunk Tools is the leading AI company revolutionizing construction. We are scaling AI agents across the jobsite and building the future of construction through intelligent automation. This is a rare opportunity to join at an inflection point during our hypergrowth phase.

Responsibilities

  • Architect and develop complex, high-volume integrations with third-party systems.
  • Own the integrations foundation end to end, including self-serve setup, scalability, rate limiting, retries, and observability.
  • Debug and support live integrations in production, including direct troubleshooting on customer calls.
  • Iterate on backend architecture to support the growing needs of thousands of users, keeping systems robust and scalable.
  • Guarantee applications are reliable, well-instrumented, and free from bugs.
  • Help shape product and architecture strategy with an informed perspective on team tools, practices, and platform decisions.
  • Work closely with product, design, and customer success to ship and support integrations with real users.

Requirements

  • 8-12 years of full-stack development experience, roughly 80% backend / 20% frontend.
  • Highly proficient in TypeScript and Node (Express).
  • Architecturally-minded, with strong experience in data schema modeling and comfort across relational databases.
  • Deep experience building read/write integrations to third-party systems, including transferring large volumes of data daily.
  • Strong grasp of data synchronization strategies: ETL, data normalization, webhooks and polling, idempotency, rate limiting/throttling, back-off and retry logic, dead-letter queues.
  • Experience with API design and lifecycle — public/external APIs, API versioning, OAuth/authentication.
  • Experience with scheduled job/worker and queue systems (Prisma, BullMQ, SQS, RabbitMQ, or similar).
  • Comfortable on customer calls — debugging live issues and gathering integration requirements directly from customers.
  • Ability to instrument a system so failures surface before a customer notices.
  • Ability to reason about infrastructure trade-offs without needing a dedicated DevOps team.
  • Proficiency in using AI tools to enhance productivity while maintaining critical judgment.
  • Ability to read and reason about generated code rather than shipping it blind.
  • Understanding of when a problem requires human judgment over AI solutions.
