About this role
About ClarkClark is building the trust infrastructure for the AI economy.
We're starting with audit and accounting workflows—document-heavy, high-trust environments where reliability, accuracy, and security matter as much as product functionality. Our platform helps firms automate complex workflows, deploy AI safely, and modernize how audit teams operate.
The RoleWe are hiring a Senior Engineer focused on document processing, OCR, and extraction quality for live workpapers.
This role will own critical systems that turn messy customer documents into usable, reliable data for Clark's AI workflows. You will work across OCR, extraction, document understanding, validation, and product workflows that depend on accurate source material.
Why This Role MattersAudit workflows depend on documents: workpapers, financial statements, trial balances, invoices, confirmations, schedules, screenshots, PDFs, and spreadsheets.
If document processing is unreliable, product quality suffers. This role directly improves extraction accuracy, customer trust, and Clark's ability to support complex audit workflows in production.
