• Represent mission, strategy, and technical challenges to candidates in a compelling way

Requirements:

• Strong proficiency in at least one backend language: Python, Java, or Node.js, with deep understanding of language internals and performance characteristics
• Proven track record of designing, building, and operating microservices architectures at scale in production
• Deep experience with cloud platforms (GCP, AWS, or Azure) including architecture decisions, cost optimization, and multi-region deployments
• Expert-level knowledge of containerization (Docker) and orchestration (Kubernetes) in production environments
• Strong experience with CI/CD pipelines, deployment strategies (blue-green, canary), and automated quality gates
• Advanced database skills: query optimization, sharding strategies, replication, and data modeling for high-throughput systems
