We are building the first artificial intelligence system for preparing tax reports that American accounting firms trust.

In just nine months, we have achieved high market compliance for our product, are generating rapidly growing, incredibly stable income, and have the support of leading investors. We are not a tool — we are the workforce that companies have been crying out for. We are building the future by expanding our team, which already numbers 30 people.

We are looking for a full-stack engineer who works quickly and thrives in a fast-paced environment. You are the type of person who sees a broken workflow, quickly understands its root cause, and fixes it in hours, not weeks. You love turning ambiguity into working software and don't wait for perfect specifications to start developing.

You are a jack-of-all-trades who is equally comfortable building a server-side service and designing a clean, responsive user interface. You pay attention to detail, but never let it get in the way of progress. You think in terms of velocity, value, and iteration, always asking: how can we get this to users faster?

As one of our first engineers, you will help shape the core product and infrastructure. You will work closely with designers, machine learning specialists, and tax experts to reimagine how this industry works — releasing products quickly, learning fast, and doing what others thought was impossible.

We use tools such as Cursor to move quickly, test ideas in a matter of days, and implement projects extremely quickly.
You will work at the intersection of product logic, machine learning, user psychology, and strictly regulated work processes.
There are no clear answers. Only subjective judgments, ambiguity, and a constant flow of information from all sides.
Your Hard Skillset

Deep experience across backend and frontend systems
Fluency in TypeScript, Python, or similar modern stacks
Comfortable with infra, APIs, databases, and debugging messy edge cases
Bonus if you’ve used AI tools to accelerate development
Even bigger bonus if you’ve worked in regulated or high-trust domains
