About The Company

Copper is a digital asset infrastructure provider offering custody, prime services, and collateral management for institutional investors. Our secure and scalable platform, including innovations like ClearLoop for off-exchange settlements, helps clients reduce counterparty risk and move capital efficiently.

About the Role

<div class="content-intro">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, Copper's Global CEO, the firm provides a comprehensive suite of custody, trading and settlement solutions that reduce counterparty 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 centralised exchanges, DeFi applications and even staking pools without the assets leaving the custody. Built on top of this state-of-the-art custody, ClearLoop is the first solution in the market that overcomes a growing industry challenge; counterparty 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, ClearLoop 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.</div>Department environment Our Technology team has remained at the forefront of blockchain technology, setting standards for the cryptocurrency infrastructure globally since the firm’s inception in 2018.
