• Reliability & Operations: A passion for building highly available, resilient distributed systems and a proven track record of solving complex operational challenges.
• Hardware: Interest or experience in hardware acceleration, specifically deploying and managing GPU-based instances for data services.
• Automation Mindset: Proven experience in designing automated recovery systems and performance-tuning algorithms.
• Modern Search Patterns: A strong interest in the evolving landscape, including Vector Database implementations, hybrid search and RAG (Retrieval-Augmented Generation).
