  • Work with cross-functional teams (frontend, product, analytics) to deliver end-to-end search features.

  • Stay ahead of industry trends in search technologies, NLP, and ML-driven search innovations.

  • Participate in code reviews, architecture discussions, and sprint planning to uphold technical excellence.

What You’ll Bring

  • A degree in Computer Science, Engineering, or equivalent practical experience.

  • 4-5+ years of backend development experience, with 3+ years focused on search technologies in eCommerce or similar high-traffic environments.

  • Expertise in Elasticsearch, Solr, or Lucene-based search engines, including indexing, query optimization, and cluster management.

  • Proficiency in Java or Python and experience building RESTful APIs for search services.

  • Hands-on experience with ML-driven search solutions, such as natural language processing (NLP), semantic search, or personalized ranking.

  • Strong knowledge of relational and NoSQL databases (e.g., PostgreSQL, MongoDB) and their integration with search systems.

  • Familiarity with cloud platforms (GCP, AWS) and containerization tools (Docker, Kubernetes).

  • Experience with CI/CD pipelines, observability tools (e.g., Prometheus, Grafana), and search performance tuning.

  • A passion for solving complex problems with a customer-first mindset.

  • Excellent collaboration skills to thrive in a cross-functional Agile environment.

Preferred Skills

  • Exposure to search operations (Ops): scaling clusters, monitoring health, and disaster recovery.

  • Experience with query understanding, auto-suggest, or synonym management in eCommerce.

  • Knowledge of vector databases or hybrid search systems combining keyword and semantic approaches.

  • Familiarity with search analytics tools (e.g., Kibana, OpenSearch Dashboards).
