Senior Site Reliability Engineer

The Sr. Platform Engineer is a senior individual contributor within the SRE Tribe, responsible for owning and evolving the containerized platform that underpins critical workloads. This role acts as a technical reference for platform reliability, resilience, and automation, ensuring infrastructure components are designed, built, and operated according to SRE and cloud-native best practices.

This engineer is expected to lead by example through hands-on contributions, deep technical expertise, and cross-team influence, particularly in the area of infrastructure bootstrap orchestration and automation at scale.

Key Responsibilities:

Platform Ownership & Reliability:

Own the end-to-end lifecycle (design, provisioning, upgrades, and decommissioning) of core platform components, including:

• Cloud infrastructure primitives

• Kubernetes clusters and cluster services

• Networking, ingress, and service discovery

• Service Mesh and supporting data-plane components

Ensure platform components are resilient by design, applying SRE principles such as:

• Fault isolation and graceful degradation

• Capacity planning and saturation control

• Reduced operational toil and clear failure modes

• Continuously assess and mitigate reliability risks, proactively improving platform stability and operational readiness.

Infrastructure Bootstrap & Automation Leadership:

Lead the design and implementation of infrastructure bootstrap orchestration, including:

• Automated cluster and environment provisioning

• Deterministic, repeatable platform bring-up and teardown

• Dependency-aware orchestration across cloud, network, and Kubernetes layers

Drive a strong Infrastructure-as-Code and GitOps-first approach, ensuring:

• Platform components are reproducible and auditable

• Changes are automated, testable, and reversible

• Manual intervention is minimized or eliminated

• Identify automation gaps and lead initiatives that significantly reduce human effort, onboarding time, and operational risk.

SRE Practices & Operational Excellence:

Apply and promote SRE practices across the platform, including:

• Clear ownership and runbooks for platform components

• Participation in on-call rotation as a platform reliability escalation point

• Incident response, post-incident reviews, and problem management

Improve platform operability by:

• Simplifying day-2 operations

• Standardizing upgrade and rollback strategies

• Reducing Mean Time to Detect (MTTD) and Mean Time to Recover (MTTR)

• Ensure platform operations align with security, compliance, and internal control requirements.
