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.

Benefits

• Competitive package
• A dynamic and innovative team
• Collaborative, inclusive working environment where your contributions are recognized
