Requirements
10+ years in backend software development and operations
Recent experience designing and operating large-scale distributed systems (last 3 years) • Fluency in one or more among Go, C/C++, Python, or Java
Proven track record of delivering mission-critical systems
Experience with cloud computing using AWS or Azure or GCP
Kubernetes API machinery and semantics: SSA, SMP, server-side dry-run, watches/informers/listers, rate-limited workqueues, finalizers, owner references, leader election, API Priority and Fairness
Controllers/operators and node daemons in Go: client-go/controller-runtime, reconciliation patterns, backoff and retry, idempotency, partitioned/sharded controllers, HA and failover
Responsibilities
Engineer and develop a unified application platform for hybrid (multi-cluster, multi-region, multi-cloud) application management using Kubernetes controllers and feedback-driven control systems to meet SLOs.
Deliver end-to-end automation for application lifecycle (deployments, rollouts, failovers, policy enforcement) to minimize manual work for users.
Drive fleet-wide optimization for cost, performance, and latency through data-informed controls and capacity management, improving $/RPS and tail latency.
Build resilient, multi-tenant control planes and workflows that safely scale to millions of pods across thousands of clusters.
Ensure reliability, security, and governance with clear guardrails, safe defaults, and automated remediation.
Partner with product and customers to turn complex orchestration problems into simple, reusable platform primitives and great developer experiences.
