- Experience with AI-driven solutions, NLP, semantic search, vector databases, or enterprise search platforms (e.g., Elasticsearch, Solr).
- Exceptional analytical skills with a proven ability to dissect complex, distributed system issues, determine root causes, and engineer sustainable technical solutions.
- Strong proficiency in inspecting application logs, tracing network requests, evaluating APM metrics, and analyzing heap and thread dumps to isolate defects.
- Proven ability to efficiently prioritize active high-severity cases and lead critical production incidents to swift resolution.
- Strong sense of accountability, dedicated customer advocacy, and a proactive mindset toward improving product reliability and runbooks.
