Staff Software Engineer (Web)

Join is SaaS for the construction industry — we bring contractors, owners, and design teams onto one platform to coordinate high-value projects. You'll work across our flagship collaboration app: shaping frontend architecture and UI quality, influencing engineering-wide standards, and shipping with urgency while weighing long-term tradeoffs. We're hiring across profiles — frontend-heavy, fullstack, and backend-heavy — and want someone T-shaped across React/Go/Postgres with deep expertise in at least one. Stack: React/TypeScript (Vite, RTL, Cypress), Go, Postgres, AWS, Terraform. You: senior/staff-level experience; strong in at least one of React, Go, or Postgres; a clear communicator who mentors and reviews well. Apply: email jon@join.build with your resume, whether you lean frontend or backend, and — if you can — a PR review you've given that had a positive impact. Mention HN.
