Senior DevOps Engineer

Senior DevOps /SRE Engineer

Role Summary

We are looking for a highly skilled and certified Senior DevOps Engineer to join our growing infrastructure team. In this role, you will be responsible for designing, building, and maintaining robust CI/CD pipelines, containerised workloads, cloud infrastructure, and observability platforms that underpin our business-critical financial applications.

The ideal candidate brings deep AWS expertise, strong Linux and scripting skills, hands-on experience with Kubernetes orchestration (EKS/ECS), Infrastructure-as-Code, and a forward-looking mindset toward GenAI-augmented DevOps practices.

Key Responsibilities

1. Cloud Infrastructure & AWS

• Architect, provision, and manage production-grade AWS environments across multiple accounts and regions.

• Lead EKS (Elastic Kubernetes Service) cluster management: node group scaling, upgrades, RBAC, pod security policies, and network policies.

• Design and manage ECS (Elastic Container Service) workloads using Fargate and EC2 launch types.

• Configure and manage AWS services: VPC, EC2, RDS, S3, IAM, Route53, ALB/NLB, ACM, CloudWatch, SNS, SQS, Lambda, Secrets Manager, Parameter Store, WAF, Shield, and API Gateway.

• Implement and maintain multi-account AWS organisation strategies with SSO, SCPs, and guardrails.

• Ensure high availability, disaster recovery (DR), and business continuity for all production workloads.

2. Containerisation & Orchestration

• Design and maintain Docker images and multi-stage Dockerfiles optimised for security and performance.

• Define Helm charts for Kubernetes application deployments across dev, staging, and production environments.

• Implement Kubernetes best practices: resource limits, health probes, HPA/VPA, pod disruption budgets, and rolling deployments.

• Manage container image repositories and lifecycle policies via ECR.

3. CI/CD & DevOps Toolchain

• Build, maintain, and improve CI/CD pipelines using Jenkins (declarative & scripted pipelines).

• Integrate automated testing, code quality gates (SonarQube), vulnerability scanning, and artifact management into pipelines.

• Manage Git repositories, branching strategies (GitFlow / trunk-based), and code review workflows.

• Implement blue-green, canary, and rolling deployment strategies to support zero-downtime releases.

• Collaborate with development teams on shift-left security and DevSecOps practices.

4. Infrastructure as Code (IaC)

• Own end-to-end Terraform codebases: module design, state management, remote backends (S3 + DynamoDB), and workspace strategies.

• Implement Terraform CI/CD with plan/apply automation, drift detection, and policy-as-code (OPA/Sentinel or Checkov).

• Maintain version-controlled IaC with documented runbooks and change management processes.

5. Observability, Monitoring & Alerting

• Design and manage a unified observability stack using Prometheus, Grafana, and New Relic.

• Build Grafana dashboards for infrastructure KPIs, application performance, and business metrics.

• Define alerting rules, SLOs, SLIs, and error budgets aligned with business-critical service SLAs.

• Implement distributed tracing and log aggregation (ELK / CloudWatch Logs / Loki).

• Conduct regular capacity planning reviews and performance tuning exercises.

6. API Gateway & Networking

• Manage AWS API Gateway (REST & HTTP APIs): throttling, WAF integration, authorisers, usage plans, and versioning.

• Design and maintain secure VPC architecture: subnets, NACLs, security groups, VPC peering, Transit Gateway, and PrivateLink.

• Implement mTLS, API security policies, and rate-limiting for all external-facing services.

7. Linux & System Administration

• Deep expertise in Linux (RHEL/CentOS/Amazon Linux/Ubuntu) administration and hardening.

• Perform kernel tuning, filesystem management, process management, and performance profiling.

• Implement OS-level security hardening aligned with CIS benchmarks.

• Manage SSH, PAM, sudoers, and user access controls in production environments.

8. Scripting & Automation

• Write production-quality Bash scripts for system automation, alerting, log rotation, patching, and health-check routines.

• Develop Python scripts for AWS automation (boto3), data processing, operational tooling, and custom Prometheus exporters.

• Build internal CLI tools and runbook automations to reduce MTTR and eliminate toil.

9. GenAI & Emerging Technology

• Actively explore and integrate GenAI tools into DevOps workflows — AI-assisted code reviews, incident summarisation, runbook generation, and intelligent alerting.

• Evaluate and prototype LLM-powered internal tools (Copilot for DevOps, ChatOps bots, AIOps capabilities).

• Stay current on AI/ML infrastructure trends and support data/ML teams with MLOps tooling where applicable.

• Experiment with prompt engineering for automation use cases and share findings for team knowledge sharing.

10. Security & Compliance

• Implement secrets management using AWS Secrets Manager, HashiCorp Vault, or equivalent.

• Conduct regular vulnerability assessments, patching cycles, and security audits of cloud and container environments.

• Ensure compliance with NBFC regulatory requirements (data residency, audit trails, access logging).

• Integrate SAST/DAST tools and container image scanning (Trivy/Snyk) into CI/CD pipelines.

11. Incident Management & Reliability

• Act as the escalation point for production incidents impacting business-critical applications.

• Lead post-incident reviews (PIRs), root cause analyses (RCAs), and corrective action implementation.

• Define and maintain runbooks, SOPs, and disaster recovery playbooks.

• Drive SRE practices including chaos engineering and game days for resilience validation.

12. Collaboration & Leadership

• Mentor junior and mid-level DevOps engineers; conduct code reviews and enforce quality standards.

• Partner with development, QA, security, and product teams to align DevOps practices with organisational goals.

• Present infrastructure roadmaps and cost optimisation proposals to technology leadership.

• Contribute to vendor evaluations, RFPs, and toolchain decisions.
