About Us

GudangKripto is a cryptocurrency exchange officially licensed and regulated by Indonesia's Financial Services Authority (OJK). We are building a trading platform that is not only fast and secure but also intuitive for users who are new to cryptocurrency.

Our platform operates 24/7 because the crypto market never sleeps. Downtime means our users lose access to their digital assets, making reliability, security, and high availability our top priorities.

What You Will Do

• Manage and maintain our cloud infrastructure, including Kubernetes clusters, cloud networking (VPCs, subnets, security groups), and supporting infrastructure components.

• Participate in ongoing cloud migration projects, including infrastructure design, provisioning, cutover execution, and post-migration validation.

• Administer production and staging PostgreSQL databases, including configuration, backup and recovery, restore drills, and performance monitoring.

• Build and maintain centralized monitoring, alerting, and logging systems to proactively detect issues before they impact users.

• Maintain and continuously improve CI/CD pipelines for development, staging, and production deployments.

• Implement infrastructure security best practices, including identity and access management, privilege management, system patching, credential rotation, and remediation of penetration testing findings.

• Develop and execute backup, disaster recovery (DR), and business continuity procedures, including regular recovery testing.

• Maintain comprehensive infrastructure documentation, including network topology, asset inventory, and incident runbooks to support daily operations and OJK audit requirements.

• Participate in the on-call rotation to respond to and resolve production incidents.

Qualifications

• Minimum of 3 years of experience in IT Infrastructure, DevOps, or Systems Engineering.

• Strong hands-on experience administering Linux servers in production environments.

• Proven experience managing containerized workloads and Kubernetes orchestration platforms (Amazon EKS, Huawei CCE, or equivalent), beyond simply deploying workloads with kubectl apply.

• Strong understanding of cloud networking concepts, including VPCs, subnets, routing, load balancers, DNS, firewalls, and VPNs.

• Experience with at least one major cloud platform, such as AWS, Google Cloud Platform (GCP), Microsoft Azure, or Huawei Cloud.

• Experience administering relational databases (PostgreSQL and/or MySQL), including backup, recovery, replication, and basic performance tuning.

• Hands-on experience with Infrastructure as Code (Terraform, Ansible, or similar tools) and scripting using Bash and/or Python.

• Good understanding of infrastructure security principles, including the principle of least privilege, network segmentation, and secrets management.

• Strong attention to documentation and change management. In a regulated industry, undocumented changes can become audit findings.

• Good written and verbal communication skills, with the ability to use English for technical documentation and cross-functional collaboration.

Preferred Qualifications

• Experience working in a cryptocurrency exchange, fintech, banking, or payment systems environment.

• Experience leading or participating in cloud migration projects between cloud providers, from planning through production cutover.

• Familiarity with security and compliance frameworks such as ISO/IEC 27001, OJK regulations related to information security, or IT audit requirements.

• Experience remediating penetration testing findings and collaborating with cybersecurity vendors.

• Basic understanding of infrastructure supporting digital asset platforms and cryptographic key management.
