Responsibilities

Infrastructure & Reliability

You will own and scale our multi-region production fleet running Linux (Ubuntu/CentOS), containerised microservices, and multi-cloud resources.
Act as the terminal-level troubleshooter during incidents, lead incident response, and keep clear, actionable runbooks up to date.
Plan and execute high-availability work including zero-downtime database upgrades, maintenance windows, and cross-region disaster recovery drills.

Observability & Security

Design, deploy and operate monitoring and log aggregation stacks using Prometheus, Grafana, Loki or the ELK stack.
Route real-time alerts to Slack, Telegram or webhooks and tune alerts to reduce noise while keeping SLA visibility.
Implement system hardening, maintain firewall postures, and configure reverse proxies or API gateways such as NGINX and Cloudflare WAF to reduce brute-force and DDoS risk.

Automation & Cost Operations

Build and maintain automated configuration and deployment pipelines using Ansible, Jenkins and Terraform with Python or Bash scripting.
Audit cloud spend and apply FinOps measures like instance right-sizing, private network peering and resource lifecycle policies to lower costs without harming SLAs.
Collaborate with engineering to standardise Git-driven CI/CD practices and ensure deployments are repeatable and safe.

Requirements

Qualifications & Experience

Minimum 2 to 3 years of hands-on commercial experience operating live Linux infrastructure and managing production deployment pipelines.
Proven experience with server administration, containerised microservices and multi-cloud architectures.
Demonstrable ownership of production availability and incident response in a fast-paced environment.

Hard Skills & Knowledge

Strong proficiency in Linux (Ubuntu or CentOS), Docker and Docker-Compose, Ansible, Terraform and Git-based CI/CD.
Deep observability experience building Prometheus and Grafana metric pipelines and log aggregation with Loki or the ELK stack.
Solid scripting ability in Python or Bash and practical experience with Jenkins or similar CI tools.
Familiarity with NGINX, Cloudflare WAF, firewall configuration and core networking concepts relevant to resilience and security.

Soft Skills & Qualities

You are highly autonomous, disciplined and comfortable with clear accountability for system stability in a flat team.
Strong written and verbal English is required; the ability to speak or write Mandarin is a strong advantage.
You communicate calmly under pressure, produce clear runbooks, and help upskill peers through documentation and knowledge sharing.
