Full Job Posting

What You'Ll Build

  • Labor Management : Build the tools superintendents run their projects on: Time & Attendance, Crew Management, Change Order Management, Progress Tracking & As-Builts, and Labor Planning
  • Craftsworker Mobile Experience : Build the craftsworker-facing mobile web app: Profiles, Stats / Achievements / Badges, the Rewards Marketplace, exportable resume, and multi-language daily notifications with SMS delivery for workers in the field
  • Integrations & API : Build the connectors that plug Ironsite into existing construction and HR stacks — Procore, Autodesk, Trimble, and payroll / ERP systems — and the API infrastructure underneath them
  • Ground Truth Tooling : Build the internal tools that power our labeling operation and feed the AI team's data engine from the Tagger Portal, GT dashboards & admin tools, and quality tooling

Technical Challenges You'Ll Solve

  • Turning raw, high-volume model output into clear, trustworthy dashboards and a production report that has to be correct and delivered by 5am
  • Building integrations with Procore, Autodesk, Trimble, and enterprise payroll/ERP systems that have inconsistent, legacy, and frequently messy data formats
  • Designing a mobile web experience usable by non-technical craftsworkers in the field: multi-language, low-connectivity, and built to drive real engagement
  • Scaling internal tooling for a growing labeling workforce while keeping data quality high enough for the AI team to train and evaluate on

What We'Re Looking For

  • [required] 5+ years of full-stack product development in production environments
  • [required] Deep expertise across the stack — modern frontend frameworks (React/TypeScript) and backend technologies (Node.js, PostgreSQL, Redis)
  • Strong background in API design, third-party integrations, and real-time data and analytics surfaces
  • Production experience with cloud infrastructure (AWS) and shipping reliable, high-scale web applications
  • Systems thinking for end-to-end product architecture and cross-team integration

Preferred Qualifications

  • Bachelors degree (B.S./B.A.) in Computer Science, Mathematics, Engineering, or related field
  • Experience with construction management software (Procore, Autodesk, Trimble), HR tech, or similar enterprise workflow tools
  • Background building analytics dashboards, reporting systems, and business intelligence surfaces
  • Experience shipping mobile web apps with offline/low-connectivity and multi-language support
  • Experience with construction, manufacturing, or similar operational industries

• San Francisco, CA (on-site)

  • Hyper competitive salary and equity package
  • Full benefits including health, dental, vision, and 401k +6% match
