Requirements

• Bachelor's degree in Computer Science, Engineering, or equivalent practical experience.

• Proven end-to-end ownership of services in a major public cloud (identity and access, networking, load balancing, storage).
• Delivered Infrastructure as Code and container orchestration in production.
• Measurable improvements to CI/CD throughput and reliability (build/test/release pipelines, rollback strategies, progressive delivery).
• Strong Linux administration and scripting/automation.
• Lead incidents and postmortems (RCAs) and implemented durable fixes.

Nice To Haves

• Knowledge of cloud, networking, and reliability: Subnets/routing, DNS/HTTP/TLS, and capacity planning.

• Experience with observability & alerting: Instrument metrics/logs/traces and create actionable alerts and dashboards.

Responsibilities

• Standardize image build practices and scanning; run and tune container orchestration for production workloads.
• Design with security from day one—partner on threat modeling and hardening, enforce safe defaults, and keep risks visible and actionable.

• Read/modify service code, improve deployment patterns and runbooks, and unblock teams with pragmatic engineering support.
