About WCT

As a WCT employee, you'll be part of a dynamic, growth-oriented culture that values collaboration, continuous learning, and excellence in execution.

Job Summary

• We are hiring a Python Platform Engineer to operate and evolve the infrastructure behind an enterprise knowledge base platform that is moving from a Confluence-focused RAG chatbot into a broader agentic knowledge system.
• Today, the platform supports Confluence/GitHub ingestion → chunking → pgvector → RAG retrieval → FastAPI serving. Over the next phase, we are expanding toward hybrid retrieval (vector + sparse + graph), multi-source ingestion, evaluation pipelines, agent infrastructure, harness and shared chat platform primitives.

What You'll Own:

• Architect and implement backend services in Python 3.11, FastAPI, Pydantic, SQLAlchemy async, and asyncpg
• Design retrieval and orchestration trade-offs around quality, latency, cost, safety, and operational simplicity
• Build production-grade agent runtime capabilities: memory boundaries, tool sandboxing, permissions, and budget controls
• Improve answer grounding, failure analysis, and citation enforcement rather than optimizing for demo behavior
• Create observability and operational feedback loops with OpenTelemetry, Prometheus/Grafana, Docker/Helm, and GitHub Actions
• Work closely with product and engineering partners to support multiple conversational surfaces through one knowledge platform
• Ingestion infrastructure across current and future content sources
• 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

Qualifications:

• Strong hands-on experience with Python 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
• Familiarity with the operational characteristics of embedding pipelines, vector search, and LLM-backed systems
• Strong observability skills across metrics, tracing, dashboards, alerting, and log analysis
• Experience with ingestion, ETL, or content-processing pipelines at scale
• Ability to think in terms of reliability, cost, latency, throughput, and recovery

Nice to Have:

• Experience with Qdrant, Neo4j, or other vector/graph infrastructure
• Experience supporting RAG, search, evaluation, or agent platforms
• Experience in enterprise or regulated environments
• Familiarity with Vault, Splunk, Artifactory, ECR
• Comfort using AI-assisted engineering workflows in day-to-day work

Compensation / Salary Range: The typical pay range for this role is: USD $110,000/Yearly - $125,000/Yearly. Factors that may affect pay within or outside of this range may include but not limited to geography/market, skills, education, experience, and other qualifications of the successful candidate.
