Role Summary

As a Senior DevOps Engineer, you will own end-to-end platform reliability and delivery automation for mission-critical lending systems. You’ll architect cloud infrastructure, standardize CI/CD, enforce DevSecOps controls, and drive observability at scale—ensuring high availability, performance, and compliance consistent with BFSI standards.

Key Responsibilities

Platform & Cloud Infrastructure

• Design, implement, and scale multi-account, multi-VPC cloud architectures on AWS and/or Azure (compute, networking, storage, IAM, RDS, EKS/AKS, Load Balancers, CDN). 
• Champion Infrastructure as Code (IaC) using Terraform (and optionally Pulumi/Crossplane) with GitOps workflows for repeatable, auditable deployments.
• Lead capacity planning, cost optimization, and performance tuning across environments.

CI/CD & Release Engineering

• Build and standardize CI/CD pipelines (Jenkins, GitHub Actions, Azure DevOps, ArgoCD) for microservices, data services, and frontends; enable blue‑green/canary releases and feature flags.
• Drive artifact management, environment promotion, and release governance with compliance-friendly controls.

Containers, Kubernetes & Runtime

• Operate production-grade Kubernetes (EKS/AKS), including cluster lifecycle, autoscaling, ingress, service mesh, and workload security; manage Docker/containerd images and registries. 

Reliability, Observability & Incident Management

• Implement end-to-end monitoring, logging, and tracing (Prometheus, Grafana, ELK/EFK, CloudWatch/Log Analytics, Datadog/New Relic) with SLO/SLI error budgets. 
• Establish on-call rotations, run postmortems, and continuously improve MTTR and change failure rate.

Security & Compliance (DevSecOps)

• Enforce cloud and container hardening, secrets management (AWS Secrets Manager / HashiCorp Vault), vulnerability scanning (Snyk/SonarQube), and policy-as-code (OPA/Conftest).
• Partner with infosec/risk to meet BFSI regulatory expectations for DR/BCP, audits, and data protection.

Data, Networking & Edge

• Optimize networking (DNS, TCP/IP, routing, OSI layers) and edge delivery (CloudFront/Fastly), including WAF rules and caching strategies. 
• Support persistence layers (MySQL, Elasticsearch, DynamoDB) for performance and reliability.

Ways of Working & Leadership

• Lead cross-functional squads (Product, Engineering, Data, Risk) and mentor junior DevOps/SREs.
• Document runbooks, architecture diagrams, and operating procedures; drive automation-first culture.

Must‑Have Qualifications

• 8–10 years of total experience with 5+ years hands-on in DevOps/SRE roles.
• Strong expertise in AWS and/or Azure, Linux administration, Kubernetes, Docker, and Terraform.
• Proven track record building CI/CD with Jenkins/GitHub Actions/Azure DevOps/ArgoCD. 
• Solid grasp of networking fundamentals (DNS, TLS, TCP/IP, routing, load balancing).
• Experience implementing observability stacks and responding to production incidents. 
• Scripting in Bash/Python; ability to automate ops workflows and platform tasks. 
• Good‑to‑Have / Preferred
• Exposure to BFSI/fintech systems and compliance standards; DR/BCP planning. 
• Secrets management (Vault), policy-as-code (OPA), and security scanning (Snyk/SonarQube). 
• Experience with GitOps patterns, service tiering, and SLO/SLI design. [illbeback.ai]
• Knowledge of CDNs (CloudFront/Fastly) and edge caching/WAF rule authoring. 
• Education
• Bachelor’s/Master’s in Computer Science, Information Technology, or related field (or equivalent experience).
