Site Reliability Engineer

Cybage Software; Pune District; Hybrid; INR 1,800,000 - 2,400,000; Full time

Job summary

Cybage Software is seeking an experienced SRE/DevOps engineer in Pune to strengthen reliability across AWS-based services built in C#/.NET. You will diagnose incidents, optimize compute and database operations, and embed reliability into new features.

You will own observability stacks, implement IaC with CloudFormation or CDK, automate deployments, and participate in blameless postmortems to drive continuous improvement. This role emphasizes collaboration and on-call readiness.

Qualifications

• 7+ years in SRE, DevOps, or platform engineering.
• Expertise in C#/.NET, cloud services, and reliability practices.
• Experience diagnosing memory leaks, thread issues, GC pressure.
• Strong scripting and automation skills.

Responsibilities

• Operate and optimize AWS compute workloads (EC2 Auto Scaling, ECS Fargate, Lambda).
• Create and manage IaC with CloudFormation or CDK.
• Automate deployments, pipelines, and DR procedures.
• Own service health dashboards and SLOs/SLIs.
• Lead RCA and blameless postmortems.

Job description

• Read, debug, and contribute to production C#/.NET code to diagnose and fix app-level reliability issues.


• Identify and resolve memory leaks, thread pool exhaustion, and GC pressure before they manifest as incidents.


• Partner with application engineers to embed reliability into new feature design and deployment practices.


• Instrument .NET services with distributed tracing and structured logging to surface runtime anomalies early.

AWS Compute & Infrastructure

• Operate and optimize EC2 Auto Scaling, ECS Fargate, and Lambda workloads — with clear judgment on when each is the right fit.


• Build and maintain infrastructure-as-code using CloudFormation or CDK for consistent, reproducible environments.


• Automate operational tasks, deployment pipelines, and disaster recovery procedures.


• Continuously reduce toil through tooling and automation, freeing the team for higher-impact engineering work.

RDS SQL Server Operations

• Manage RDS SQL Server deployments including Multi-AZ failover configuration and read replica setup.


• Operate backup and point-in-time recovery (PITR) processes and validate restore procedures regularly.


• Diagnose and resolve performance issues: slow queries, missing indexes, and blocking chains.


• Capacity plan and scale database infrastructure to support transaction volume growth.

Observability & Monitoring

• Build and maintain observability stacks using CloudWatch metrics, log insights, and alarms; AWS X-Ray for distributed tracing.


• Own service health dashboards, SLOs/SLIs, and drive data-driven reliability improvements.


• Design alerts that surface signal — not noise — and ensure on-call responders have the context to act quickly.


• Conduct root cause analysis (RCA) on incidents and lead blameless post-mortems to capture lessons and prevent recurrence.

Networking & Security

• Design and maintain secure AWS network topologies: VPCs, subnets, security groups, and NACLs.


• Configure and manage ALB/NLB routing, Route 53 DNS, and TLS certificate lifecycle via ACM.


• Author and review least-privilege IAM policies; audit roles and resource-based policies for over-permissioning.


• Support compliance and security controls relevant to a PCI-regulated payments environment.


• Participate in on-call rotation to respond to production incidents and drive swift resolution.


• Define and track error budgets; use them to balance velocity and reliability investment.


• Communicate status updates clearly during incidents and coordinate cross-functional response.


• Maintain and improve runbooks, escalation paths, and on-call health over time.

Cross-Functional Partnership

• Collaborate with platform engineering teams on architecture decisions and scalability requirements.


• Share observability and reliability best practices with application teams.


• Mentor engineers on SRE principles and operational excellence.


• 7+ years in SRE, DevOps, platform engineering, or a systems-focused software engineering role.


• C#/.NET engineering ability — can read, debug, and contribute to production code; experience diagnosing memory leaks, thread exhaustion, and GC pressure.


• AWS compute fluency: hands-on depth across EC2 Auto Scaling, ECS Fargate, and Lambda, with informed opinions on when to use each.


• RDS SQL Server operational experience: Multi-AZ failover, read replicas, backup/PITR, slow query analysis, and blocking chain resolution.


• Native AWS observability proficiency: CloudWatch (metrics, logs, alarms), X-Ray, and infrastructure-as-code via CloudFormation or CDK.


• AWS networking and security competence: VPCs, security groups, ALB/NLB, Route 53, TLS/ACM, and least-privilege IAM.


• SLO discipline: experience defining SLIs/SLOs against real metrics, running blameless postmortems, and carrying an on-call pager.


• Strong scripting ability (PowerShell, Python, or Bash) for automation and operational tooling.


• Excellent communication skills and a collaborative, blameless engineering mindset.


• Genuine openness to adopting AI tools and a willingness to experiment with new technology to work smarter and faster.
