We are looking for a Founding Engineer

with extremely high ownership.

Not someone who waits for tasks.

Not someone who wants a comfortable 9 to 5.

Someone who sees a broken system, fixes it, ships it, and owns the result.

What you’ll do

Build core product infrastructure across frontend, backend, AI, backtesting, broker integrations, and trading systems.

Ship fast. Talk to users. Make product decisions. Own full features from idea to production.

You will work directly with the founders and the core team, with massive responsibility from day one.

What we’re looking for:

A-player engineer.

High agency.

Fast learner.

Practical builder.

Obsessed with shipping.

Strong product intuition.

Low ego, high standards.

Comfortable with ambiguity.

Wants to build something massive.

Bonus if you have experience with trading, AI, infra, fintech, brokers, backtesting, or developer tools.

This is not a normal engineering job.

This is for someone who wants to become one of the most important people in the company.

Early team. Real ownership. Real upside. Very high expectations.

Location: Tel Aviv, in person.

• Comp: Strong salary + meaningful equity.
