Join

Join builds collaboration software for the construction industry — helping contractors, owners, and architects coordinate on high-value projects. We are hiring multiple senior/staff engineers across frontend-heavy, fullstack, and backend-heavy profiles. Especially looking for 1–2 engineers with architect-level frontend skills (React, TypeScript, state management, performance) to own UI quality and level up the team, but also interested in strong Go/Postgres or infra/ops backgrounds. Day-to-day you'll write code (25–75%), review PRs (25–50%), and pair/mentor/document (10–20%). You'll act as a technical lead on projects, break down large efforts, and influence architectural decisions across the org. Small cross-functional teams with a designer, PM, and EM. Stack includes React, TypeScript, Golang, Postgres, GraphQL/Apollo, Vite, Cypress, Terraform, AWS (ECS, RDS, Lambda). Light use of Elastic and interest in event-driven patterns. Fully remote. To apply: send resume to jon@join.build. If possible include a PR review you've given that had a positive impact (or a description/snippet if confidential).
