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.
