About Abacus

Abacus is reinventing how accounting firms operate by building AI agents that automate the tedious, repetitive workflows that teams currently face. Our core engine combines advanced OCR and LLMs to deliver truly intelligent back-office automation. We're already working with large enterprise clients, generating meaningful revenue, and backed by top-tier investors. We’ve accomplished all of this as a team of two, and we’re excited to grow our team. If you want to shape the future of AI-powered operations and own meaningful technical work from day one, this is the place.

The Role

We're hiring a 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. This is a rare opportunity to join a high-growth company as an early engineer with massive autonomy and influence over product and technical direction.

Build and deploy new automation features for tax firms

Willingness to complete a technical take-home exercise as part of the process

Nice-to-haves:

Why Join Us

No ceiling on ownership or growth

Significant equity and high-leverage role at a fast-growing startup
