SRE/DevOps/Platform Engineer

We are seeking a Senior Site Reliability Engineer (8+ years of experience) to drive the reliability, availability, scalability, and operational excellence of our global payment platform. You will take end-to-end ownership of production observability, incident response, service-level management, and cloud infrastructure reliability across mission-critical payment systems spanning Europe and Asia. Key Responsibilities Incident Management & On-Call : Participate in a follow-the-sun production on-call rotation as a senior incident responder. Lead incident management during SEV1/SEV2 events to optimise MTTR and operational effectiveness. Production Operations : Diagnose, triage, mitigate, and coordinate the resolution of complex production incidents across payment services, Kubernetes (EKS) platforms, databases, Kafka pipelines, and cloud infrastructure. Database HA & Disaster Recovery : Own database high availability and disaster recovery end-to-end — Aurora/RDS Multi-AZ, replication, automated backups, PITR, and regular, documented restore drills so recovery never depends on one person. SLO & Reliability Engineering : Define, implement, and maintain SLOs, SLIs, error budgets, alerting standards, and operational readiness processes across distributed services. Drive the shift from log-count alerting to symptom- and metric-based alerting. Cost Optimisation : Own AWS cost efficiency across our multi-account environment — right-sizing, Savings Plans/RI coverage, data transfer, and storage lifecycle. Continuous Optimisation : Drive systemic reliability improvements through infrastructure automation, observability enhancement, capacity planning, performance tuning, and post-incident root-cause analysis (RCA). Security & Compliance : Partner with global engineering teams to strengthen architectural resilience, security posture, and operational maturity in PCI-DSS-regulated payment environments. Technical Leadership : Mentor engineers, eliminate operational toil through automation, and influence engineering teams to adopt resilience-by-design practices. Requirements Qualifications & Requirements Experience : 8+ years of hands-on experience in Site Reliability Engineering, Platform Engineering, DevOps, or Cloud Infrastructure roles supporting high-availability, mission-critical production systems. Core Technical Stack : Strong expertise in AWS (multi-account, EKS), Kubernetes, Terraform, PostgreSQL, Redis, Kafka, Linux, networking, and modern observability platforms (e.g., Coralogix, PagerDuty, Prometheus, Grafana). Database HA & DR : Proven experience with database high availability and disaster recovery — replication, failover, backup strategies, and hands-on restore operations. Distributed Systems Mastery : Deep understanding of distributed systems architecture, high availability, disaster recovery, capacity planning, and microservices orchestration. SRE Methodology : Deep knowledge of core SRE principles, including SLO/SLI design, error budget management, alert governance, and toil reduction. Location & Communication : Based in Hong Kong or Shenzhen. Excellent command of English (written and spoken) to lead cross-functional incident responses and collaborate seamlessly with global teams; Mandarin required for local collaboration. Nice to Have Experience in payment, banking, fintech, or other highly regulated environments with strict PCI-DSS, security, and uptime standards. Experience with AI-assisted operations (AI agents for incident diagnosis, runbook automation). Leadership & Operational Excellence Ownership : Demonstrates strong end-to-end accountability for service reliability and customer impact under high pressure. Structured Problem Solving : Applies a systematic and data-driven approach to troubleshooting, telemetry analysis, and incident resolution in complex distributed environments. Crisis Management : Proven ability to command cross-functional incident response efforts, align stakeholders, and maintain clear communication during critical outages. Engineering Culture : Champions a blameless post-incident culture, operational readiness, continuous learning, and technical mentorship.
