Associate Software Engineer

Since being founded in 2018, Copper has been building the standard for institutional digital asset infrastructure with a focus on custody, collateral management, and prime services. Led by Amar Kuchinad, the firm provides a comprehensive suite of custody, trading and settlement solutions that reduce counter party risk and bring greater capital and operational efficiency to digital asset markets. At the heart of Copper's offering is Multi‑Party Computation (MPC) technology – the gold standard in secure custody.

Copper’s multi‑award winning custody system is unique in that it can be connected to centralized exchanges, DeFi applications and even staking pools without the assets leaving the custody. Built on top of this state‑of‑the‑art custody, Clear Loop is the first solution in the market that overcomes a growing industry challenge; counter party risk with exchanges. This solution underpins a full prime services offering, connecting global exchanges, and enabling customers to trade and settle directly from the safety of their MPC‑secured wallets.

By reducing settlement time for transfers to a few milliseconds (without blockchain network dependency) and offering enhanced security measures, Clear Loop is rapidly reshaping the way asset managers trade and manage capital. In addition to industry‑leading security certifications, Copper has one of the strongest insurance coverages in the industry from an A+ rated insurer, positioning the firm as the partner of choice for institutions seeking to safeguard their assets.

At Copper, we keep innovation, openness, and curiosity at the centre of everything we do. Here, bold ideas get the spotlight, learning is constant, and diversity shapes our team from the ground up.

Jump into a fast‑moving, dynamic team that loves a challenge and knows how to have fun along the way. Collaboration is just as important as results—you’ll be surrounded by smart, driven colleagues in London and across our APAC, Switzerland, UAE, and US offices.
