Your role in the team
- Develop the search engine behind ABOUT YOU, covering query understanding, entity resolution, and semantic vector search in Node.js/TypeScript.
- Blend OpenSearch relevance, embedding similarity, and behavioral re-ranking signals into unified search results.
- Build search-index pipelines (entities, synonyms, k-NN product vectors) streaming data from BigQuery into OpenSearch.
- Integrate LLMs and embedding models (Gemini, Vertex AI) under tight latency budgets with caching and fallback layers.
- Guard search relevance using golden lists, regression suites, and continuous A/B experiments.
- Shape architecture alongside our Tech Lead and collaborate closely with data analysts, engineers, and product managers.
Our expectations of you
Qualifications
- You love investigating the “why” behind search outcomes and turning those findings into actionable technical improvements.
- In-depth expertise in Elasticsearch/OpenSearch (mappings, custom analyzers, percolators, scoring functions), beyond 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
- 3+ years of experience building scalable, low-latency backend APIs (Node.js/TypeScript preferred, or fast-converting from Java, Go, or Kotlin).
