Job Description

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.

This is a hybrid position. Expectation of days in office will be confirmed by your hiring manager.

Qualifications

Strong hands-on experience with:

  • Public Cloud platforms (AWS preferred, Azure)
  • Kubernetes at scale, previous experience administrating productive kubernetes environments
  • Service Mesh technologies (e.g., Istio preferred, App Mesh, Linkerd)

Strong Understanding Of

  • Observability tooling and Golden Signals concepts
  • Incident management concepts and oncall operations
  • Infrastructure as Code (e.g., Terraform)
  • Cloud-Native containerized micro-services architecture
  • Strong collaboration and communication skills.
