Senior Manager - IT Systems Engineering

Supreme IT Park, India · Tower A, IndiaRegularPosted Jul 20, 2026

We are seeking a talented individual to join our GIS at Marsh. This role will be based in Mumbai. This is a hybrid role that has a requirement of working at least three days a week in the office.

Senior Manager – Site Reliability Engineering (SRE) / Reliability Operations

Role Overview

We are looking for a Senior Manager – SRE / Reliability Operations to drive reliability engineering practices across critical services and platforms. In this role, you will establish and mature SLI/SLO/SLA and error budget governance, lead operational excellence (ITIL-aligned incident/problem/change), and partner closely with engineering, architecture, and DevOps teams to reduce toil through automation and improve resilience, observability, and release reliability.

We will count on you to:

SRE fitness: SLI/SLO/SLA & error budget management
- Define, implement, and continuously improve SLIs and SLOs for services/products in collaboration with product and engineering teams
- Align SLAs with business expectations and ensure operational commitments are measurable and reportable
- Create and manage error budgets, including:
  - Error budget policies and burn-rate thresholds
  - Release gating recommendations based on error budget status
  - Executive reporting on reliability posture and trade-offs
- Build SLO dashboards and reliability scorecards for leadership and stakeholders
- Conduct periodic SLO reviews and drive corrective actions when reliability trends degrade
Software engineering, automation, and toil reduction
- Identify operational toil and repetitive manual work; design and deliver automation to reduce or eliminate it
- Develop tooling/scripts/services using standard languages (e.g., Python, Go, Java, PowerShell, or similar) aligned to the team’s stack
- Implement self-healing patterns (automated remediation, auto-rollback, auto-scaling, safe retries)
- Standardize operational runbooks and embed automation into runbooks wherever possible
- Improve operational efficiency through event-driven workflows and platform capabilities
System design: reliability, resiliency, and stability
- Partner with architecture and engineering teams to design systems for:
  - High availability, fault tolerance, and graceful degradation
  - Scalability and performance under load
  - Robust dependency management and timeout/retry/circuit-breaker strategies
- Lead or contribute to resiliency reviews, failure-mode analysis, and capacity planning
- Design and facilitate resiliency testing (dependency failure simulations, controlled fault injection where appropriate)
- Define and validate RTO/RPO targets and align with disaster recovery strategies
Cloud adoption & reliability enablement
- Support cloud adoption/migration initiatives (AWS/Azure/GCP as applicable), ensuring reliability-by-design
- Establish operational patterns for cloud-native services including:
  - Auto-scaling, health checks, multi-AZ/region strategies
  - Infrastructure-as-Code (IaC) practices in partnership with platform/DevOps teams
- Contribute to secure, compliant, and standardized cloud operations (guardrails, baselines, tagging/monitoring standards)
Operational management (ITIL-aligned)
- Own and/or drive improvements in:
  - Incident Management: triage, mitigation, communications, major incident handling, post-incident reviews
  - Problem Management: root cause analysis, trend analysis, corrective/preventive actions, known error database hygiene
  - Change Management: change risk assessment, change validation, release readiness, change success metrics
- Facilitate and standardize post-incident reviews (PIRs) focusing on blameless learning, actionable follow-ups, and prevention
- Improve operational governance and documentation quality (runbooks, SOPs, service ownership, on-call readiness)
Observability & monitoring (Datadog)
- Build and maintain observability practices using Datadog, including metrics, logs, traces (APM), synthetics, and RUM (as applicable)
- Establish dashboard standards for service health, SLO compliance, and operational KPIs
- Design alert strategies focused on actionable alerts, noise reduction, correlation, and routing
- Implement monitoring for golden signals (latency, traffic, errors, saturation) and service-specific signals
- Tune alerts based on incident learnings and error budget burn rates; reduce false positives
DevOps & CI/CD reliability
- Collaborate with DevOps teams to improve CI/CD pipelines for reliability and speed, including:
  - Automated testing strategy integration (unit/integration/smoke)
  - Deployment strategies (blue/green, canary, rolling, feature flags)
  - Automated rollback and deployment verification
- Improve release reliability and change failure rate through quality gates and operational readiness checks
- Promote “shift-left” reliability: testing, observability instrumentation, and operational requirements embedded early in the SDLC

Deliverables / Outcomes (What success looks like)

Defined SLIs/SLOs and error budgets for critical services with leadership-ready reporting
Measurable reduction in toil and faster operational response through automation
Improved reliability KPIs (availability, MTTR, incident volume/severity, change failure rate)
Mature Datadog dashboards and alerting with reduced noise and improved signal quality
Standardized incident/problem/change practices with consistent PIR execution and follow-through
Increased platform resiliency validated via reviews and targeted resiliency testing

What you need to have:

7+ years (or appropriate level) experience in SRE / Production Operations / Platform Engineering / DevOps supporting enterprise applications
Strong knowledge of:
- SLA/SLO/SLI concepts and practical error budget implementation
- Incident response, troubleshooting, and root cause analysis
- System reliability patterns (timeouts, retries, backoff, circuit breakers, bulkheads)
Proven capability to build automation using one or more programming/scripting languages (e.g., Python/Go/Java/PowerShell)
Hands-on experience with Datadog (dashboards, monitors, APM/tracing/logs correlation)
Working knowledge of CI/CD pipelines and modern DevOps practices
Understanding of cloud fundamentals and cloud operations (AWS/Azure/GCP), including reliability considerations

What makes you stand out?

Experience implementing SLO programs at scale across multiple teams/services
Experience with Kubernetes and container platforms (or managed equivalents)
Infrastructure-as-Code experience (Terraform/CloudFormation/Bicep)
Familiarity with ServiceNow (or similar) for ITSM processes and reporting
Experience with chaos testing or resiliency validation exercises
Strong security and compliance awareness in production operations (least privilege, auditability)

Behavioural Competencies

Strong stakeholder management and ability to explain reliability trade-offs to leadership
Structured problem-solving and data-driven decision making
Ability to operate calmly during major incidents and lead technical bridges
Ownership mindset and continuous improvement orientation
Strong documentation discipline and ability to drive standardization
