Copper is a digital asset technology company dedicated to helping institutional investors safely acquire, trade, and store crypto assets.

Built and led by Dmitry Tokarev, a software and financial engineering specialist, 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.

Department environment

This is an exciting entry level opportunity for a software engineer to join our Clearloop team at Copper to build new back-end microservices and integrate with cryptocurrency exchanges.

Clearloop provides clients with a network of exchanges on which they can trade digital assets. The exchanges currently integrated with ClearLoop include OKX, Deribit,, bitfinex and PowerTrade, which provide clients with access to over 50% of the available market. ClearLoop minimizes risk by holding assets in a trust structure, and by enabling clients to trade on exchanges without placing assets there – meaning that if an exchange were to become insolvent, they would not lose funds. This is unique in the market.
