Job Description
What You’ll Do

• Document Ingestion & Pipelines: Design and maintain scalable data processing pipelines for ingesting, parsing, cleaning, and indexing multi-format unstructured and semi-structured documents from varied knowledge sources.


• Knowledge & Retrieval Systems: Architect and optimize Retrieval-Augmented Generation (RAG) pipelines, semantic and hybrid search workflows, and context-assembly engines to deliver accurate, high-relevance information to downstream application models.


• Metadata & Knowledge Organization: Implement robust schemas for document versioning, chunking strategies, metadata enrichment, taxonomy management, and granular permission-aware context filtering.


• Back-End API & Service Development: Build reliable, high-throughput RESTful and streaming APIs in Python to expose context and knowledge services seamlessly to internal and external applications.


• Performance & System Efficiency: Optimize background processing, memory overhead, database indexing, caching strategies, and queue-based batch operations to minimize latency and manage operational compute costs.


• Evaluation & System Observability: Implement monitoring, logging, and continuous evaluation frameworks to track context retrieval precision, indexing health, API performance, and data drift in production.


• Clean Architecture & Scalable Design: Maintain clean abstraction layers across data stores, embedding services, and language models to keep core domain logic modular, decoupled, and vendor-agnostic.

What You Bring

• 6+ years of experience designing, building, and maintaining production back-end microservices and data pipelines using Python.


• Hands-on experience with document parsing, text chunking, metadata enrichment, and building scalable pipelines for unstructured knowledge processing.


• Solid understanding of modern retrieval paradigms, including semantic search, vector indexing, lexical/keyword search, hybrid search, and RAG architectures.


• Deep familiarity with modern Python back-end practices, asynchronous programming (async/await), relational/non-relational database design, and background job processing systems.


• Proven experience building clean RESTful/streaming APIs, applying object-oriented/functional design patterns, and maintaining vendor-neutral software abstractions.


• Experience with cloud environments, containerized deployments (e.g., Docker, Kubernetes), message queues, caching layers, and CI/CD pipelines.


• Strong commitment to testing, technical documentation, code reviews, and clear cross-functional collaboration with product, data, and front-end engineering teams.
