Devops Engineer (Japanese speaking)

About The Role We are looking for a hands-on Senior DevOps Engineer to strengthen our platform engineering team. In this role you will design, build, and operate cloud infrastructure, drive CI/CD automation, and embed GitOps practices that let product teams ship with confidence. You will work closely with infrastructure, security, and application teams — translating complex technical solutions into measurable business outcomes while raising the DevOps bar across the organization.

Key Responsibilities Infrastructure & Cloud- Design, develop, and manage cloud infrastructure using an IaC tool such as Terraform, Bicep, or CloudFormation.

• Administer and harden Linux servers for DevOps and application workloads, ensuring security and operational stability.
• Manage containerized workloads with Kubernetes and Docker, including cluster configuration, scaling, and lifecycle management. CI/CD & Automation- Build and maintain CI/CD pipelines using one or more tools such as GitHub Actions, Jenkins, or Azure DevOps.
• Implement GitOps workflows using a tool such as FluxCD with Helm charts to enable automated, declarative delivery.
• Develop automation scripts in Bash and/or Python to drive operational efficiency and environment management. Observability & Reliability- Operate and optimize a monitoring and observability stack — such as Grafana/Prometheus, ELK/OpenSearch, Dynatrace, or Datadog.
• Implement and support robust logging, alerting, and incident response strategies. Collaboration & Leadership- Collaborate cross-functionally with infrastructure, security, and other internal teams to deliver reliable, scalable services.
• Communicate clearly with internal stakeholders and customers, translating technical solutions into business value.
• Lead or contribute to technical decision-making, best practice definition, and DevOps knowledge sharing within the team. Must Have Experience- 2–7 years of professional experience in a DevOps or Infrastructure Engineering role.
• Professional-level hands-on experience with AWS, Azure or GCP (deep expertise in one is required). Infrastructure as Code- Proficiency in at least one IaC tool: Terraform (preferred), Bicep, or CloudFormation.
• Strong grasp of IaC best practices: state management, module design, drift detection, and GitOps workflows. CI/CD & GitOps- Hands-on experience with at least one CI/CD platform: GitHub Actions, Jenkins, or Azure DevOps.
• Experience with GitOps tooling — FluxCD preferred — using Helm charts for declarative delivery.
• Familiarity with version control systems: Git or Azure DevOps Git. Platform & Systems- Strong Linux system administration and troubleshooting experience.
• Skilled in scripting and automation using Bash and/or Python.
• Experience managing containerized workloads on Kubernetes and/or Docker. Observability- Solid knowledge of at least one monitoring/logging stack: Prometheus/Grafana, ELK, OpenSearch, Dynatrace, or Datadog.
• Strong understanding of DevOps best practices including security, reliability, and scalability. Communication- Good communication skills in Japanese and Vietnamese; English is an advantage
• Proven ability to document, present, and advocate technical decisions clearly. What Seniority Means In This Role We are not just looking for someone who can execute tasks — we expect a Senior DevOps Engineer to operate with a high degree of autonomy, ownership, and technical leadership. Here is what that looks like day-to-day:

Ownership & Autonomy- You take end-to-end ownership of infrastructure domains — from design through delivery and ongoing operations — without needing close supervision.

• You proactively identify gaps in reliability, security, or scalability and drive improvements rather than waiting to be assigned work. Technical Depth & Judgement- You make sound architectural decisions independently, weighing trade-offs between tooling choices, cost, maintainability, and risk.
• You are the go-to person for complex infrastructure problems, debugging production incidents, and designing resilient systems.
• You stay current with the DevOps ecosystem and can evaluate new tools or practices critically before adopting them. Influence & Mentorship- You actively raise the team’s technical bar — through code reviews, pairing sessions, internal workshops, or written documentation.
• You mentor junior and mid-level engineers, providing constructive feedback and helping them grow into independent contributors.
• You contribute to defining team standards, best practices, and DevOps culture within the engineering organization. Stakeholder Communication- You communicate infrastructure decisions, risks, and trade-offs clearly to both technical peers and non-technical stakeholders.
• You translate platform work into business value — uptime, velocity, cost savings — and advocate for platform investment when needed. Nice to Have- Relevant DevOps certifications: CKA, Terraform Associate, or Azure DevOps Expert.
• BSc / MSc in Computer Science, Engineering, or an equivalent technical discipline.
• Working experience at an IT services or managed services provider.
• Experience with multi-cloud or hybrid cloud deployments.
• Awareness of security and compliance frameworks such as SOC 2, ISO 27001, or CIS Benchmarks — hands-on experience is a plus.
• Exposure to SRE practices and site reliability concepts.
