• Build a 0-to-1 Enterprise Search product with a strong focus on scalability, performance, and relevance.
• Lead proof-of-concept efforts to validate ideas quickly and align with business goals.
• Architect and implement robust, maintainable, and scalable systems for indexing, querying, and ranking.
• Develop data pipelines, implement automation for reliability, and ensure strong observability and monitoring.
• Work closely with Product Managers and Designers to translate user needs into data-driven, intuitive search experiences.
• Guide and support junior engineers through code reviews, technical direction, and best practices.
• Collaborate with cross-functional teams (data, platform, infra) to deliver cohesive and high-impact solutions.

What We're Looking For

Must-Have Skills:

• Familiarity with LLMs, RAG pipelines, or knowledge graph integrations.
• Deep expertise in information retrieval, search engines (Lucene, Elasticsearch, Solr).
• Experience with vector search, embeddings, and/or neural ranking models (e.g., BERT, Sentence Transformers).
• Strong programming skills in Java, Python, or Go.
• Familiarity with scalable data processing frameworks (e.g., Spark, Kafka, Flink).
• Good understanding of system design, APIs, caching, and performance tuning.

Nice-to-Have:

• Experience with enterprise content connectors (SharePoint, Confluence, Jira, etc.).
• Experience working in a SaaS, B2B, or product-first environment.

Qualifications

• 6-10+ years of experience building backend systems, infrastructure, or AI platforms at scale.
• Proven ability to own and deliver complex features independently, collaborate across teams, and mentor peers in a fast-paced environment.
• Demonstrated experience leading initiatives with significant technical and organizational impact - from setting direction to aligning stakeholders and driving execution.
