Senior DevOps Engineer

Roles and responsibilities

Work with Engineering to create Proof of Concepts, define AWS elements to be used based on business requirements.

Analyze and present comparison of multiple AWS solutions, non-AWS alternatives to executives - for final decision making.

Responsible for building and setting up new development tools and infrastructure utilizing knowledge in continuous integration, delivery, and deployment (CI/CD), Cloud technologies, Container Orchestration and Security. Build and test end-to-end CI/CD pipelines, ensuring that systems are safe against security threats.

In depth expertise with the Kubernetes stack Operators, CRDs, Policies, TLS.

• Kubernetes Application Developer

• EKS, Fargate, ECS, ECR, Lambda, Helm
• CI/CD Pipeline design (AWS Code pipeline, Code Deploy) CKA
• Expertise in API integration and development

• Infrastructure Automation and Management:

  • Infrastructure as Code (IaC): Design and implement automated infrastructure provisioning and management using IaC tools like Terraform, Ansible, Chef, or Puppet.
  • Configuration Management: Use automation tools to ensure consistent configuration management across environments and ensure system reliability.
  • Containerization and Orchestration: Manage and scale containerized applications using Docker, Kubernetes, or other container orchestration platforms. Automate the deployment of containers to ensure scalable and reliable environments.
  • Cloud Infrastructure: Manage cloud infrastructure (AWS, Azure, GCP) and utilize cloud-native services to optimize cost, performance, and availability.

• Monitoring and Logging:

  • System Monitoring: Implement monitoring solutions using tools like Prometheus, Nagios, Datadog, Zabbix, or New Relic to track system performance and application health.
  • Log Management: Use centralized logging solutions like ELK Stack (Elasticsearch, Logstash, Kibana) or Splunk to collect, analyze, and visualize logs for system troubleshooting, performance optimization, and security monitoring.
  • Alerting and Incident Management: Set up alerting systems and respond proactively to issues by using tools like PagerDuty, Opsgenie, or VictorOps to reduce downtime and enhance system reliability.

• Collaboration and Communication:

  • Cross-Functional Collaboration: Collaborate with development, operations, and QA teams to ensure efficient software delivery pipelines, smooth infrastructure management, and alignment of goals and processes.
  • Mentorship and Leadership: Provide mentorship to junior DevOps engineers and promote best practices in automation, CI/CD, and system administration.
  • Stakeholder Communication: Act as a liaison between different technical teams and non-technical stakeholders to communicate DevOps strategies, progress, and challenges.

• Performance Optimization:

  • System Tuning and Optimization: Continuously monitor and improve system performance, ensuring that infrastructure, applications, and services are running optimally. Work on reducing latency, improving throughput, and scaling systems as needed.
  • Cost Optimization: Work with cloud providers and teams to optimize costs by selecting the right resources, optimizing workloads, and leveraging appropriate services and automation tools to manage usage efficiently.

• Security and Compliance:

  • Security Automation: Integrate security practices into the CI/CD pipeline and ensure that security measures are automated. Use tools like Vault, OWASP, and SonarQube for vulnerability scanning and compliance checks.
  • Access Control and IAM: Implement secure access control policies using Identity and Access Management (IAM) tools, ensure that least privilege principles are followed, and manage permissions effectively.
  • Compliance and Auditing: Ensure that infrastructure and deployment pipelines adhere to security policies and compliance requirements (e.g., GDPR, HIPAA, PCI-DSS).
