Job description

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.

Department environment

We aim to achieve a balance between corporate and start-up culture, and at the same time be close to product solutions. Therefore, we divide our department into small self-sufficient teams that can make decisions on their own. This applies to all stages of product production: from conceptualisation to architecture, to build, to release, to iteration and support.

Key Responsibilities of the role

We’re looking for a skilled Backend Engineer to join our Core team. This team is responsible for building and maintaining the foundational microservices that power critical parts of our platform, includingauthorisation, invoicing, notifications, and user management.

As a Backend Engineer on this team, you'll be working on systems that directly support and secure the entire product ecosystem. Your work will be central to enabling internal teams and delivering seamless, secure experiences to our users.

Your experience, skills and knowledge

• Design, build, and maintain scalable and reliable backend services in a microservices architecture.
• Write clean, well-tested, and maintainable code.
• Collaborate with product managers, frontend engineers and QA engineers on new features.
• Participate in code reviews, testing, and debugging to maintain quality of our products.
• Ensure high availability, performance, and security of the services you own.
• Support and solve problems from clients and stakeholders.

Skills and experience

• Experience building software with a JVM language: Scala, Kotlin, or Java.
• Familiarity with relational databases such as PostgreSQL.
• Strong understanding of REST APIs.
• An understanding of the critical importance of testing, well-versed and able to build automated tests of server-side code.
• Excellent communication skills. Able to formulate well defined questions and appropriately articulate ideas, problems, and solutions to various stakeholder groups.
• Capacity to adapt in a fast changing environment and being able to work with elements of a tech stack that you haven’t faced before.

Desirable

• Experience working within microservice based architecture.
• Possessing an understanding of distributed systems.
