• Experience with event streaming platforms such as Kafka and modern observability tools such as Grafana or Honeycomb
• Experience deploying and operating services in cloud environments such as AWS, ideally with Docker and Kubernetes
• Strong ownership mindset, with the ability to take complex problems from definition through to production
• Experience improving the reliability of business-critical systems and turning recurring incidents into lasting improvements
• Strong communication skills and a collaborative approach to working across Engineering, Product, Compliance, Risk, and Operations
