Job description

Role Summary

We are looking for a self-motivated, highly driven DevOps Engineer who thrives on technical ownership and autonomous task execution. In this role, you will bridge day‑to‑day infrastructure engineering and long‑term reliability by taking loosely defined requirements, breaking them down into concrete technical tasks, and driving them to completion with minimal day‑to‑day oversight. You will design, automate, and maintain cloud infrastructure, CI/CD pipelines, and observability frameworks while partnering closely with software development and platform teams.

Key Responsibilities

1. Individual Task Execution & Infrastructure Ownership
   • Autonomous Delivery: Take ownership of infrastructure deliverables and feature sets from inception to deployment; operate independently between milestone check‑ins.
   • Problem Decomposition: Translate high‑level architectural requirements and loosely defined tickets into well‑scoped, actionable technical tasks and execution plans.
   • Root‑Cause Problem Solving: Investigate, diagnose, and permanently resolve complex production and CI/CD infrastructure failures rather than applying temporary patches.
2. Infrastructure as Code (IaC) & Cloud Engineering
   • Design, provision, and maintain secure, scalable cloud infrastructure using Terraform, CloudFormation, or equivalent IaC frameworks.
   • Manage cloud networking, compute capacity, security groups, and IAM policies following least‑privilege principles.
3. CI/CD & Release Automation
   • Build, optimize, and troubleshoot automated CI/CD release pipelines to enable fast, safe, and repeatable application deployments.
   • Debug build/release failures at both the framework and infrastructure layer (e.g., container build failures, permissions, compute bottlenecks).
4. Reliability, Observability & Operational Excellence
   • Implement proactive monitoring, alerting, and log aggregation (e.g., Datadog, Prometheus, Grafana, CloudWatch) to ensure system visibility.
   • Participate in on‑call rotations and incident triage; write post‑incident reviews (PIRs) and implement preventative automations.
   • Champion operational excellence, system availability, and performance benchmarking.
5. Collaboration & Continuous Improvement
   • Proactively communicate timelines, architectural tradeoffs, and roadblocks early to squad leads and stakeholders.
   • Contribute to team design/architecture reviews, write concise technical specs, and mentor junior engineers.

Required Qualifications & Technical Skills

• Experience: 3–5+ years of dedicated experience in DevOps, Site Reliability Engineering (SRE), or Cloud Infrastructure Engineering.
• Cloud Platforms: Strong hands‑on proficiency in public cloud environments (AWS), including core services (VPC, EC2, EKS, S3, IAM, Route53, RDS).
• Infrastructure as Code (IaC): Solid experience writing modular, reusable Terraform or CloudFormation scripts.
• CI/CD & Automation: Proven track record building and managing CI/CD pipelines (e.g., GitHub Actions, Jenkins).
• Containers & Orchestration: Solid working knowledge of Docker and container orchestration (Kubernetes / ECS).
• Scripting & Automation: Proficiency in at least one scripting/programming language (Python, Bash, or Go).
• OS & Networking: Strong Linux systems administration fundamentals, networking concepts (DNS, TCP/IP, HTTP/S, load balancers), and security best practices.

Key Behavioral Competencies (Self-Drive & Mindset)

• High Motivation & Ownership: Follows through on commitments end‑to‑end with pride of ownership; rolls up sleeves to solve blockers rather than waiting for direction.
• Clear & Proactive Communication: Consistently communicates project progress, identifies risks before starting major tasks, and flags roadblocks without disappearing into low‑impact work.
• Critical Thinking & Simplicity: Looks at multiple solutions, validates trade‑offs in context, and actively reduces unnecessary system complexity.
• Continuous Learning (Shugi): Eager to explore new tools and techniques, actively solicits constructive feedback, and continuously refines internal processes (Shikumika).

Preferred / Nice‑to‑Have Qualifications

• Experience with database migrations, replication tools (e.g., Debezium, pglogical, AWS DMS), or PostgreSQL administration.
• Experience with GitOps methodologies and deployment tools (ArgoCD).
• Relevant cloud or Kubernetes certifications (e.g., AWS Solutions Architect / DevOps Engineer, CKA).

Rakuten Shugi Principles

• Always improve, always advance. Only be satisfied with complete success – Kaizen.
• Be passionately professional. Take an uncompromising approach to your work and be determined to be the best.
• Hypothesize – Practice – Validate – Shikumika. Use the Rakuten Cycle to success in unknown territory.
• Maximize Customer Satisfaction. The greatest satisfaction for workers in a service industry is to see their customers smile.
• Speed!! Speed!! Speed!! Always be conscious of time. Take charge, set clear goals, and engage your team.
