Abacus is hiring its first Founding Engineer to own and expand the core machine learning engine behind Abacus. You’ll report directly to the co-founders and work in person from our SF office, with massive autonomy and influence over product and technical direction. In your first 3–6 months, you’ll scale the ML extraction engine using LLMs and OCR, own backend architecture, and ship greenfield features to expand automated workflows for tax firms. This is a rare growth opportunity. #J-18808-Ljbffr Praxis
