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, secure 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
