Job summary

Mumba Technologies, Inc. in Gurgaon is seeking an experienced Site Reliability Engineer to build and operate highly reliable, scalable, secure, and observable systems in a hybrid work model with 3 days in the office.

You will lead incident response, design comprehensive observability, and implement AI-assisted reliability practices while mentoring junior SREs. The role spans AWS, Kubernetes, IaC, security, and performance optimization.

Qualifications

• Lead incident response, RCAs and track actions to closure.
• Design and own observability stack across metrics, logs, traces and events.
• Drive toil reduction by eliminating repetitive ops work.

Responsibilities

• Lead incident response, conduct RCAs and ensure action items are tracked to closure.
• Build and maintain runbooks, playbooks and escalation frameworks for proactive and reactive response.
• Drive toil reduction by identifying repetitive operational work and engineering it away.
• Design and own the full observability stack — metrics, logs, traces and events using Prometheus, Grafana, OpenTelemetry, Datadog, Dynatrace.
• Build intelligent alerting that reduces noise, surfaces actionable signals.
• Implement distributed tracing and dependency mapping for end-to-end visibility across microservices.
• Leverage AI/ML for anomaly detection, predictive alerting and root-cause analysis.
• Own Kubernetes cluster operations — autoscaling, networking, upgrades, cost optimization.
• Mentor SREs and drive engineering standards and best practices.

Job description

Location: Gurgaon (Hybrid 3-Days in the office)

About the Role:

We are looking for an experienced Site Reliability Engineer (SRE) to help build and operate highly reliable, scalable, secure, and observable systems. The role involves hands-on work across AWS, Kubernetes, Infrastructure as Code, observability, automation, security, and AI-driven SRE practices.

Reliability & Availability

• Lead incident response, conduct RCAs and ensure action items are tracked to closure
• Build and maintain runbooks, playbooks and escalation frameworks for proactive and reactive response
• Drive toil reduction by identifying repetitive operational work and engineering it away

Observability

• Design and own the full observability stack — metrics, logs, traces and events — using tools like Prometheus, Grafana, OpenTelemetry, Datadog, Dynatrace or similar
• Build intelligent alerting that reduces noise, eliminates alert fatigue and surfaces actionable signals
• Implement distributed tracing and dependency mapping to provide end-to-end visibility across microservices
• Drive adoption of continuous profiling and real user monitoring (RUM) for proactive performance management

AI Adoption in SRE

• Leverage AIOps platforms to enable anomaly detection, predictive alerting and automated root cause analysis
• Implement AI-assisted incident triage — using LLM-powered tools to summarise incidents, suggest fixes and accelerate MTTR
• Build and maintain ML-powered capacity forecasting models to optimise infrastructure spend and prevent resource saturation

Security & Vulnerability Management

• Embed security-as-reliability principles — treating security incidents with the same urgency as availability incidents
• Own issue remediations across infrastructure (OS, containers, dependencies)
• Integrate SAST, DAST and SCA tools into CI/CD pipelines to shift security left
• Design, build and maintain cloud-native infrastructure on AWS using Infrastructure as Code (Terraform, Pulumi) & drive rightsizing, reserved capacity planning and cost anomaly detection
• Own Kubernetes cluster operations — autoscaling, resource management, networking and upgrade strategy

Leadership & Culture

• Mentor and guide junior and mid-level SREs — conducting technical reviews and pair debugging sessions
• Define and evolve SRE team standards, best practices and engineering principles
• Collaborate closely with product, development and security teams as an embedded reliability partner
• Contribute to on-call rotation and drive continuous improvement of on-call experience
• Represent SRE in architecture reviews, sprint planning and cross-functional forums

The Competitive Edge

AEM Administration

• Own end-to-end reliability and availability of AEM environments — Author, Publish, Dispatcher and AEM as a Cloud Service (AEMaaCS) — across dev, staging and production
• Monitor and manage AEM instance health, optimise Dispatchers, Manage DAM, OSGi Configurations, replication queues.

Exposure to CDN

• Experience with Cloudflare - CDN, Workers.
