PDF Engine Architect

Generating PDFs reliably at scale from HTML (with correct tagging for accessibility and true PDF/A archival compliance) is a much harder problem than it looks, and most naive approaches fall apart under real document complexity or concurrent load. We build deterministic HTML-to-PDF compilation pipelines using Playwright render pools, producing properly tagged PDF/UA output for accessibility and PDF/A output for archival requirements. This is for products generating documents, reports, or forms at volume where PDF output has to be accessible, archival-compliant, and consistent every single time. You get a rendering pipeline that produces the same correct output whether it's document one or document ten thousand.

This is a capability we deliver for you as a service, not a role we’re hiring for.

How We’d Approach This

A clear, staged plan, not a black box

These are the service-specific steps inside our six-step process.

  1. 1

    Review your document templates and PDF requirements (accessibility, archival, volume) to scope the render pipeline.

  2. 2

    Build a pilot render pipeline against representative documents and verify PDF/UA and PDF/A compliance directly.

  3. 3

    Review sample output with your team, including accessibility testing on the tagged PDF structure.

  4. 4

    Scale the pipeline with a render pool architecture that holds up under your real document volume.
