Candidate Profile

→    Strong data modelling and database design capability

→    Comfortable operating in ambiguity and startup environments

→    Product-minded engineer who enjoys customer interaction and rapid iteration

→    Strong communication skills and ownership mentality


Nice to Have

→    Experience within fintech, investment platforms, or financial data products

→    Exposure to alternative investments or hedge fund workflows

→    Experience building AI-enabled or agentic systems

→    Previous early-stage startup or 0→1 experience


Package

→    $175k-$225k base salary

→    Meaningful equity package

→    On-site in NYC

→    Founding engineer opportunity (employee #4)


Why Join?

→    Build in a massive $24T market undergoing major digital transformation

→    Work directly with experienced founders from Goldman Sachs and leading hedge funds
