Role Overview
Job type : Contract
Duration : 6 months
We are seeking a highly skilled and resilient Senior DevOps Engineer to join our engineering team. In this role, you will design, build, and maintain the robust cloud infrastructure that powers our high-transaction, large-scale platforms. You will be responsible for ensuring 99.99% uptime, seamless scalability during peak traffic surges (like flash sales), and accelerating our deployment pipelines.
If you are passionate about infrastructure-as-code, obsessed with automation, and thrive in optimizing high-throughput architecture, we want you on our team.
Key Responsibilities
1. Infrastructure Architecture & Scaling
Design, deploy, and manage highly available, fault-tolerant, and autoscaling AWS infrastructure.
Optimize infrastructure to handle massive traffic spikes, high concurrent user volumes, and heavy transactional databases typical of large-scale e-commerce platforms.
Implement efficient caching strategies and Content Delivery Networks (CDNs) to minimize latency.
2. CI/CD & Deployment Automation
Build, maintain, and optimize robust Continuous Integration and Continuous Deployment (CI/CD) pipelines to ensure fast, safe, and zero-downtime releases.
Implement deployment strategies such as Blue/Green or Canary deployments to mitigate risk during production updates.
3. Monitoring, Alerting & Observability
Establish comprehensive monitoring, logging, and alerting systems to proactively identify and resolve performance bottlenecks before they impact end-users.
Conduct regular load testing and chaos engineering to simulate high-traffic events and ensure system resilience.
4. Security, Compliance & Cost Optimization
Implement industry-standard security practices, including IAM role management, data encryption (at rest and in transit), and network isolation (VPCs, Security Groups).
Audit and optimize cloud spend, ensuring high performance is balanced with cost-efficient resource utilization.
