Our expectations of you
Qualifications
- You love investigating the "why" behind search outcomes and turning those findings into actionable technical improvements.
- Real depth in Elasticsearch/OpenSearch (mappings, custom analyzers, percolators, scoring functions) beyond just basic query clients.
- Strong algorithmic intuition for ranked data (merging, deduplication, score blending, and latency trade-offs).
- You're excited to bridge backend engineering and ML by serving model scores, embeddings, or LLM features in production.
- Fluent English communication skills and a pragmatic, data-curious mindset.
Experience
- 5+ years of experience building scalable, low-latency backend APIs (Node.js/TypeScript preferred, or fast-converting from Java, Go, or Kotlin).
