Infra DevOps Engineer

About the role

BIT (formerly Matrixport), a global digital asset financial services and infrastructure group headquartered in Singapore, is looking for a DevOps Engineer who sits at the intersection of operations and modern, AI-accelerated development. You will own the infrastructure powering the company's products and services, designing, automating and keeping it fast, reliable and cost-efficient. This is a hands-on role that treats infrastructure as a product.

Key responsibilities

• Design, build and operate infrastructure across its full lifecycle for a broad mix of services such as CMDB, OA, monitoring and alerting.
• Manage and scale Kubernetes clusters, automating node lifecycle and cost optimisation with tools such as Karpenter.
• Define infrastructure as code and drive GitOps-based CI/CD so every change is reviewable, repeatable and auditable.
• Partner with developers to remove friction, embedding AI-assisted and vibe-development practices into day-to-day delivery.

Required profile

• Strong self-motivation and responsibility.
• Structured thinking, able to break down complex problems.
• Pursuit of engineering excellence, not satisfied with "just making it work".
• Focus on developer experience, aiming to empower developers.
• Systematic approach to incident post-mortems and root cause analysis.
• Nice to have: Bachelor's degree in Computer Science, Engineering or a related discipline, and basic understanding of agent loops and how agentic AI systems operate.

Required skills

• Familiarity with Linux and shell scripting.
• Container and orchestration: Docker, Kubernetes, Helm.
• Infrastructure as code with Terraform and Karpenter.
• GitOps-based CI/CD workflows (GitLab CI, ArgoCD).
• Maintenance of common AWS services (VPC, AMI, EKS, EC2, S3, CloudFront, etc.).
• Golang or Python development on top of middlewares such as MySQL and Redis.
• Hands-on experience of vibe development.
