Job description

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.

Qualifications

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