About Magnetic

AI Tax Preparer for CPA firms. Backed by Y Combinator.

About the role

Magnetic is hiring a skilled Software Engineer to join our core development team. You’ll be responsible for building and maintaining the backend systems that power our AI-driven tax prep platform - including model pipelines, data extraction logic, and integrations with tax software, as well as improving our client-facing touchpoints. You’ll work closely with sales, product, and tax operations to ship features that directly improve speed, accuracy, and reliability for our customers.

What they're looking for

  • Vision-Language pipelines that process and extract structured data from unstructured client tax documents, relying on AI models, deterministic rules, and human-in-the-loop corrections
  • Systems to test and improve extraction accuracy on complex tax forms, handwritten notes, brokerage statements, and K-1s
  • Distributed cloud infrastructure to process thousands of client files concurrently across multiple firms and tax seasons
  • Integrations with major tax software systems, file portals, and document management tools
  • Features to improve our own client-facing surface area (intake, output artifacts, review process)
