Senior SRE - APAC Payments Platform, Self-Service IaC

REAP Limited; Hong Kong; Sur place; HKD 600 000 - 1 200 000; Plein temps

Résumé du poste

REAP Limited is building a Site Reliability Engineering practice to own the reliability of a payments platform across multi-region AWS. You will lead by example, drive technical excellence, and help engineers level up in a distributed, flat team.

You will set SLIs/SLOs, contribute to incident response, and push for full IaC coverage while automating provisioning and observability. This role demands hands-on expertise in AWS, Terraform, Kubernetes, and PCI DSS environments.

Qualifications

• Real SRE practice with defined SLOs, error budgets or incident postmortems.
• Strong Linux and system fundamentals including networking and admin tasks.
• Deep Terraform skills: state management, modules, and large-scale IaC migration or greenfield buildouts.
• Advanced AWS knowledge in multi-account/multi-region environments (Control Tower, IAM, VPC, RDS).
• Experience operating ECS/Fargate and production Kubernetes at scale, including cluster lifecycle and upgrades.
• Serverless and event-driven systems: Lambda, SQS, EventBridge, with failure mode awareness.
• GitOps and CI/CD pipelines with practical tooling (Argo CD, GitHub Actions).
• Observability discipline: logging, metrics, tracing with modern tools and standards adoption.
• Languages: Python, Go or Bash for automation.
• Ownership across a service's life cycle, including security and compliance in payments.

Responsabilités

• Define SLIs/SLOs in collaboration with product and engineering teams.
• Participate in on-call rotations and mature incident response and blameless postmortems.
• Drive Infrastructure as Code coverage, reducing manual provisioning and drift.
• Consolidate Terraform estate into modular, governed codebases with drift detection.
• Automate account provisioning and regional standups for repeatable deployments.
• Build self-service interfaces so product teams can provision, deploy, observe without tickets.
• Design epoxy environments for isolated production-like testing and automatic cleanup.
• Implement industry-standard observability and actionable alerting across platforms.
• Own cloud operations for PCI DSS and regulated financial systems.
• Embed security into infra: secrets, least privilege, network segmentation.
• Support AI-assisted engineering with tooling for code, reviews, and incident analysis.
• Collaborate with product teams to treat the platform as a product and align with customers.
