• Integrate network changes into CI/CD pipelines with linting policy-as-code unit/integration tests and automated rollbacks.

• Develop scripts and APIs for inventory validation and orchestration to improve change velocity and reduce error rates.

Monitoring Telemetry and SLOs:

• Implement and operationalize SNMP/streaming telemetry NetFlow/IPFIX and flow logs for health capacity and security visibility.

• Define and track SLIs/SLOs (availability latency packet loss) and build alerts runbooks and dashboards for proactive incident detection.

• Perform trend and capacity analyses; recommend scaling actions and optimization.

Cross-Team Collaboration and Operations Excellence:

• Partner with SRE platform and security teams on architecture reviews incident response post-incident improvements and capacity/performance planning.

• Participate in on-call rotations execute change windows and contribute to root-cause analysis and problem management.

• Document and socialize operational models guardrails and standards; align designs with platform roadmaps.

Documentation Reviews and Standards:

• Produce high-quality design docs diagrams and runbooks; maintain up-to-date inventories and topology maps.

• Conduct and participate in design and change reviews; contribute to reference architectures patterns and reusable modules.

• Share knowledge through peer mentoring brown-bags and code/document reviews to uplift team proficiency.

Core Responsibilities

Planning & Execution:

• Independently manage work monitoring timelines and deliverables to ensure projects or initiatives stay on track and meet requirements; proactively prioritize work and adapt to resource or timeline shifts suggesting adjustments to maintain project efficiency.

Collaboration & Partnership:
