We are hiring a Python AI Engineer to operate and evolve the infrastructure behind an enterprise knowledge base platform as it transitions from a Confluence-focused RAG chatbot into a broader, agentic knowledge system.

Today, our platform supports Confluence/GitHub ingestion → chunking → pgvector → RAG retrieval → FastAPI serving. In our next growth phase, we are expanding toward hybrid retrieval (vector + sparse + graph), multi-source ingestion, robust evaluation pipelines, agent infrastructure, and shared chat platform primitives.

If you are passionate about building scalable, reliable, and production-grade AI infrastructure rather than just chasing demo behavior, we want to hear from you.

Req.#1093687315

Responsibilities

• Architect and implement robust backend services using Python 3.11, FastAPI, Pydantic, SQLAlchemy async, and asyncpg

• Design trade-offs around retrieval quality, latency, cost, safety, and operational simplicity

• Build production-grade agent runtime capabilities, including memory boundaries, tool sandboxing, permissions, and budget controls

• Improve answer grounding, failure analysis, and citation enforcement for enterprise-grade dependability

• Create comprehensive observability and operational feedback loops using OpenTelemetry, Prometheus/Grafana, Docker/Helm, and GitHub Actions

• Ingestion infrastructure across current and future content sources

• Full-stack observability across application, pipeline, database, and model-serving behavior

• Cost, latency, throughput, and failure-mode management for AI-heavy workloads

• Release workflows that validate AI behavior changes, not just code compilation

• Partner closely with product and engineering teams to support multiple conversational surfaces through a unified knowledge platform

Requirements

• Strong, hands-on Python experience in platform, automation, or infrastructure-heavy environments

• Experience building CLI tools using Python, Golang, or Rust

• Hands-on experience with LangGraph, LangChain, pgvector, and modern retrieval pipelines

• Experience designing evaluation frameworks for LLM-backed systems, including regression detection and quality measurement

• Strong experience with Docker, Helm, GitHub Actions, and Kubernetes-oriented workflows

• Systems Understanding: Familiarity with the operational characteristics of embedding pipelines, vector search, and LLM-backed systems

• Strong skills across metrics, tracing, dashboards, alerting, and log analysis

• Experience with ingestion, ETL, or content-processing pipelines at scale

• An innate ability to think in terms of reliability, cost, latency, throughput, and disaster recovery

• Nice to have

• Experience with Qdrant, Neo4j, or other vector/graph infrastructure

• Prior experience supporting RAG, search, evaluation, or agent platforms

• Background in enterprise or highly regulated environments

• Familiarity with enterprise tooling such as Vault, Splunk, Artifactory, or ECR

• Comfort leveraging AI-assisted engineering workflows in day-to-day work
