Job Description

We are looking for a battle-tested DevOps / SysOps Engineer to take complete end-to-end ownership of our multi-environment production infrastructure. The role focuses on building resilient, secure, and cost-effective systems, acting as a terminal-level troubleshooter during critical production incidents, writing clear runbooks, and designing automation frameworks.

Job Requirements

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.
