Digital Asset Platform Support

Description

Engineer for the future of digital finance. At Citi, our Technology organization doesn’t just support the financial ecosystem—we help redefine it. As blockchain innovation, digital assets, and tokenized financial products continue to reshape global markets, our teams are building secure, scalable, and resilient platforms that matter. We are seeking a motivated team member to join our Digital Assets Production Support team in North America. This role focuses on the stability, reliability, and security of our digital asset platforms, wallet infrastructure, and blockchain‑connected systems operating in production. The ideal candidate will work closely with Production Support, Engineering, Cybersecurity, Risk, and business partners to ensure seamless operation of digital asset services, including wallet management, blockchain integrations, consensus‑driven systems, and digital asset transaction pipelines. The role includes supporting daily operational activities, rapidly resolving incidents, and contributing to platform scalability and regulatory compliance.

Responsibilities

• Understand how Digital Asset Production Support contributes to broader technology and business objectives, including secure transaction processing, blockchain operations, and digital asset lifecycle management.

• Provide operational support for digital asset wallets (hot, cold, hardware, and multi‑sig setups), blockchain nodes, and related platforms in production.

• Support cryptocurrency transaction flows, reconciliation processes, and monitor risk flags or anomalous activity.

• Participate in incident management, problem management, post‑incident reviews, and continuous improvement efforts relating to blockchain and digital asset platforms.

• Monitor blockchain node health, wallet operations, transaction latency, mempool activity, and network congestion.

• Collaborate with engineering teams to enhance platform stability, improve wallet automation, and strengthen key security controls.

• Partner with vendor teams and managed services supporting blockchain infrastructure, wallet services, and custody platforms.

• Assist in collecting capacity and performance metrics for blockchain nodes, transaction throughput, and wallet operations to support forecasting and scaling plans.

• Support digital asset onboarding activities following established standards and regulatory expectations.

• Participate in resilience initiatives including disaster recovery, failover testing, key‑material backup validation, and blockchain node redundancy exercises.

• Support automation opportunities for wallet operations, node monitoring, reconciliation tasks, and security checks.

• Maintain strong observability practices—monitoring, logging, tracing, alerting—across digital asset and blockchain platforms.

• Ensure operational health of production environments across blockchain nodes, custody systems, wallet frameworks, and related infrastructure.

• Contribute to knowledge‑sharing, documentation improvements, and structured runbooks for digital assets operations.

Qualifications

• 5–8 years of relevant experience in platform operations, technical support, Site Reliability Engineering, or blockchain/Digital Asset support.

• Solid understanding of blockchain fundamentals, including distributed ledgers, consensus mechanisms, cryptographic hashing, and public/private key architecture.

• Experience with scripting or coding in Java, Python, Go, or similar languages preferred.

• Experience with Red Hat OpenShift or similar Kubernetes technologies preferred.

• Experience supporting production systems in high‑pressure environments, preferably in financial services or e‑trading‑like environments.

• Experience working with databases such as Postgres, Oracle, MongoDB, or Redis preferred.

• Knowledge of blockchain protocols (Bitcoin, Ethereum) and operational aspects of running nodes or interacting with RPC endpoints.

• Ability to explain complex technical concepts to technical and non‑technical partners including compliance, business, and senior stakeholders.

• Strong analytical, problem‑solving, and troubleshooting skills, especially in fast‑moving blockchain environments.

• Experience with observability tools (e.g., Prometheus, Grafana, Splunk, ELK) is preferred.

• Experience collaborating with cross‑functional teams including risk, compliance, cybersecurity, and business units.

• Familiarity with CI/CD or automation tools is beneficial.

Education

• Bachelor’s/University degree required.
