Description

  • Architect and implement the next-generation scientific search engine for billions of scientific data points.
  • Engineer hybrid search pipelines that combine keyword, structured metadata, and vector-based retrieval.
  • Design custom ranking logic, reciprocal rank fusion, and relevance tuning for search quality.
  • Own and operate the search platform infrastructure with a focus on availability, scalability, performance, and observability.
  • Develop and maintain backend services and APIs in Python and TypeScript.
  • Collaborate with Applied AI Scientists to productionize embeddings, transformer models, and chemical fingerprints.
  • Build scientific entity resolution and knowledge graph pipelines from unstructured text.
  • Design systems for chemical and biological entity extraction and linking across documents and datasets.
  • Continuously evaluate and improve search quality using metrics such as precision@K, recall@K, and MRR.
  • Contribute to architectural decisions, technical strategy, and platform-wide improvements while mentoring engineers.

Requirements

  • 10+ years of backend or platform engineering experience building distributed, production-grade systems.
  • Hands-on experience with search technologies such as Elasticsearch, OpenSearch, Lucene, or vector databases.
  • Strong understanding of semantic search, embeddings, transformers, similarity scoring, ranking logic, relevance tuning, and hybrid retrieval.
  • Expert-level coding skills in TypeScript and Python for building robust APIs and backend services.
  • Experience building and operating microservices or search infrastructure on cloud platforms, preferably AWS.
  • Experience with containerization, CI/CD, observability, and performance tuning.
  • Familiarity with scientific or unstructured data processing, such as documents, tables, analytical results, or experimental datasets.
  • Strong problem-solving skills and the ability to translate ambiguous scientific workflows into engineered systems.
  • Excellent communication and collaboration skills for working with scientists, AI researchers, and product teams.
  • Exposure to NLP, LLMs, embedding generation, or retrieval-augmented workflows.
  • Experience with large-scale data platforms such as Databricks, Lakehouse architectures, or distributed indexing systems.
  • Experience with cheminformatics tools and libraries such as RDKit, molecular fingerprints, similarity metrics, or substructure search (nice to have).
  • Prior experience implementing chemical search systems, including SMILES parsing, normalization, or chemical indexing (nice to have).
  • Knowledge of vector databases or embedding stores such as OpenSearch to support semantic search and RAG (nice to have).

Benefits

  • 100% employer-paid benefits for eligible employees and immediate family members.
  • Unlimited paid time off (PTO).
  • 401K retirement plan.
  • Flexible working arrangements, including remote work.
