We do business in 180+ countries operating at a scale few can match. From deploying advanced AI to helping shape global markets, we build systems that matter.

Citi is looking for a Digital Assets Production Support & SRE Lead to own the reliability and operational integrity of business-critical digital asset platforms, including blockchain-connected systems, digital wallets, and high-throughput transaction processing infrastructure. In this role, you will serve as a technical authority — bridging engineering, operations, and business teams to resolve complex platform challenges and drive measurable improvements in system stability. You will directly shape how Citi's digital asset capabilities perform at scale, influencing both the day-to-day resilience of the platform and its long-term engineering direction.
Responsibilities:
- Lead production support and site reliability engineering for mission-critical digital asset platforms, ensuring system availability, performance, and continuity across blockchain-connected environments and transaction processing systems.
- Own end-to-end incident management — from detection through resolution and post-incident review — using observability tools such as Splunk, Grafana, Prometheus, ELK, and OTEL to minimise business impact and reduce recurrence.
- Identify and define system enhancements by analysing existing platform logic, diagnosing root causes of failures, and delivering targeted, scalable solutions that improve operational outcomes.
- Partner with product owners, business analysts, and engineering teams across multiple technology areas to document system impacts, surface support requirements, and align on delivery priorities.
- Evaluate risk exposures, security vulnerabilities, and platform gaps — communicating findings clearly to technical and business stakeholders and proposing actionable mitigation strategies.
- Develop and maintain automation scripts and tooling using Python, Java, or equivalent languages to reduce manual intervention, accelerate incident resolution, and improve platform observability.
- Act as a technical mentor to junior engineers, guiding workload allocation, sharing expertise, and raising the overall engineering standard of the support function.
