Backend Engineer

About the Company

Zuma Labs is a disruptive technology startup building force multipliers for systemic industries. Our first two products, Venetian and Squawk, target the over-the-counter (OTC) trading markets. We work closely with our customers and count a large publicly traded brokerage among our partners. Trading technology is an old industry… and we’re here to change that.

At Zuma Labs, we value creativity, entrepreneurship, and a genuine passion for problem-solving -but what we’re really looking for are born-and-bred hackers with a healthy disrespect for the status quo.

You’ll be given broad tasks that support the company’s vision, with incredible autonomy over how to achieve them. Your work will apply the latest analytical techniques to real-world problems, prioritising working solutions over perfect answers.
