    Help us turn gigabytes of construction drawings into clear, actionable dataβ€”one React component at a time.

     

    - What we do: AI-driven workflows that let estimators pull quantities and costs from complex PDF drawing sets.  
    - Stage: Seed-funded, revenue-generating, aiming for a Series A in 2025.  
    - Why join now: Real customers are pushing our roadmap faster than our current front-end team can build.
     

    What you’ll do in your first year:

    - Ship viewer enhancements that lazy-load heavy pages and handle thousands of annotations smoothly;
    - Add real-time collaboration: show teammates’ live cursor positions and selection outlines inside the viewe;
    - Migrate the data layer away from Apollo in new features, introducing generated query hooks along the way; 
    - Replace AG Grid screens with modern, accessible, virtualised tables;  
    - Own vertical slices: spec, build, demo to real estimators, iterate quickly. 

     

    Tech you’ll work with:

    - Next.js 14 / React 19 with TypeScript;
    - Apryse WebViewer for page-by-page PDF rendering (some pages take 10 s+ to loadβ€”performance matters);
    - React context & hooks (we’re retiring Jotai);  
    - GraphQL API (Apollo Client today, moving toward lighter generated fetchers); 
    - Legacy AG Grid viewsβ€”being replaced by TanStack Table or bespoke grids;  
    - Jest + React Testing Library (unit tests encouraged, not required);
    - GitHub Actions CI, Sentry for prod observability. 

     

    You’ll thrive here if you…
    - Have 3-5 years of React + TypeScript in production.  
    - Understand component composition, hooks, and modern routing patterns. 
    - Have touched GraphQL and are open to new fetch/cache approaches.  
    - Communicate clearly in English and enjoy async collaboration.  
    - Can share a GitHub repo or project you’re proud of.

     

    Nice-to-haves:
    - Experience with PDF canvases, Apryse/WebViewer, virtualised tables, or GraphQL subscriptions;
    - Familiarity with Jest / Testing Library.
     

    Join our stellar team at Drawer.AI, where excellence meets opportunity! Experience the exceptional; enjoy a competitive salary and career advancement and the outstanding work environment we take pride in. Elevate your professional journey with us – because we believe in creating success together. Build a better future with us!
