Principal Site Reliability 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, 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. 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. Department Overview The Engineering department is the backbone of Copper; entrusted with the critical responsibility of building and securing the infrastructure that safeguards billions of dollars in digital assets. We operate at the intersection of traditional institutional finance and decentralized blockchain technology. Team Purpose We believe the best infrastructure comes from curious minds working openly together. Our engineering organisation brings together people with diverse backgrounds and experiences who genuinely enjoy solving hard problems. We foster a blame‑free, intellectually honest environment where you’re encouraged to take thoughtful risks and think big. You’ll have the autonomy to own meaningful projects while gaining the support you need to grow your skills and advance your career. Role Purpose We’re looking for a site reliability engineer at the intersection of software development and systems engineering. In this role, your focus will be delivering the reliability, performance, and uptime our clients depend on, whilst continuously improving how our systems operate. Day‑to‑day, you’ll tackle complex infrastructure challenges through thoughtful engineering and automation. Rather than fighting fires, you’ll work to prevent them. You’ll analyse system capacity and performance, identify bottlenecks and build solutions that scale across our department, not just one team. You will collaborate closely with the DevOps team, but focusing primarily on reliability engineering, operational excellence, and production readiness across the broader engineering organisation. Key Responsibilities Shape SRE: Define how we think about reliability, observability, and operational excellence. Drive the adoption of SRE principles across the organization while building the systems and processes that make those principles measurable – think SLIs, SLOs and error budgets. Scale Through Automation: Champion architectural improvements that enhance both system reliability and deployment velocity. Provide consultation on system architecture, building reusable platforms and frameworks, planning capacity needs, and conducting production readiness reviews to ensure services launch and operate successfully. Drive Technical Excellence: Engage in and improve the lifecycle of microservices, from inception through deployment, operation, observability, and continuous refinement. Lead Through Influence: Partner with engineering and product leadership to embed reliability into our product development lifecycle. Conduct blameless post‑mortems and drive systemic improvements in incident management. Mentor engineers across the organisation on SRE practices, helping teams take ownership of their service reliability. While this role begins as an IC position, it will play a key part in shaping the future of SRE at Copper. Skills and Experience Essential Experience in designing, analysing, and troubleshooting distributed systems or micro‑services architectures. Established expertise in observability and incident management. Proven experience in driving organizational change. Excellent communication skills, with a systematic problem‑solving approach. Desirable Experience working with production workloads in AWS. Experience working in financial services or similarly regulated environments. Interest in blockchain based technologies and/or decentralised finance. Master's degree in Computer Science or Engineering. Benefits Paid Time Off – A minimum of 35 days of paid time off per year, inclusive of annual leave and public holidays. Employees also receive one additional day of annual leave for each year of service. Comprehensive Medical Insurance – Inclusive of dental, optical, audiology, and mental health coverage, with medical history disregarded. Life Insurance. Enhanced Pension Contributions – Includes an enhanced employer matching contribution. 24/7 Employee Assistance Programme (EAP). We are an equal opportunity employer. We embrace diversity and equal opportunities in a serious way. We are committed to building a team that represents a variety of backgrounds, perspectives, and skills.
