We are hiring a Senior Python Engineer to help drive the evolution of an enterprise knowledge base platform.
This platform is transitioning from a Confluence-focused RAG chatbot to a comprehensive agentic knowledge system. You will play a key role in expanding the platform’s capabilities, including hybrid retrieval, multi-source ingestion, evaluation pipelines, agent infrastructure, and shared chat platform primitives.
Responsibilities
- Architect and develop backend services using Python 3.11, FastAPI, Pydantic, SQLAlchemy async, and asyncpg
- Design retrieval and orchestration strategies that balance quality, latency, cost, safety, and operational simplicity
- Build robust agent runtime features such as memory boundaries, tool sandboxing, permissions, and budget controls
- Enhance answer grounding, failure analysis, and citation enforcement to improve reliability and accuracy
- Establish observability and operational feedback loops with OpenTelemetry, Prometheus, Grafana, Docker, Helm, and GitHub Actions
- Collaborate with product and engineering teams to support multiple conversational interfaces through a unified knowledge platform
- Develop ingestion infrastructure for current and future content sources
- Implement observability across application, pipeline, database, and model-serving layers
- Manage cost, latency, throughput, and failure modes for AI-intensive workloads
- Create release workflows that validate AI behavior changes beyond code compilation
Requirements
- Minimum 3 years of relevant professional experience in software engineering
- Extensive hands-on experience with Python in platform, automation, or infrastructure-focused environments
- Experience building command-line tools using Python, Golang, or Rust
- Practical knowledge of LangGraph, LangChain, pgvector, and modern retrieval pipelines
- Experience designing evaluation frameworks for LLM-powered systems, including regression detection and quality assessment
- Strong background with Docker, Helm, GitHub Actions, and Kubernetes-based workflows
- Understanding of embedding pipelines, vector search, and operational aspects of LLM-driven systems
- Advanced observability skills, including metrics, tracing, dashboards, alerting, and log analysis
- Experience with ingestion, ETL, or large-scale content-processing pipelines
- Ability to approach system design with considerations for reliability, cost, latency, throughput, and recovery
- Excellent oral and written communication skills in English at B2+ level or higher
Nice to have
- Experience with FastAPI for building web APIs
- Familiarity with Grafana and Splunk for monitoring and log analysis
- Knowledge of Qdrant, Neo4j, or other vector and graph database infrastructure
