TECH LEAD, RAG & Knowledge Ingestion

Job responsibilities:

• Technical leadership: Define and own the RAG platform’s architecture and standards, make trade-offed design decisions, drive high-impact backend improvements across the pipeline, and communicate a clear technical roadmap.
• Hands-on backend engineering: Build and evolve ingestion, processing, and retrieval services/APIs, strengthen async pipelines (RabbitMQ, retries, backpressure), enhance parsers, and optimize indexing on Qdrant/Elasticsearch for quality and latency.
• Retrieval and document intelligence: Partner with AI engineers to advance chunking, embeddings, metadata, and RAG patterns; integrate Python services for agentic workflows; improve retrieval via better indexing/enrichment/evaluation and adopt OCR/layout/table extraction when it moves the needle.
• Technical leadership for the team: Mentor and unblock engineers through reviews and pairing, elevate reliability/performance/observability/testing, and support hiring and onboarding without primary people-management duties.
• Platform ownership: Run production delivery via Helm/Kubernetes and ArgoCD GitOps, enhance observability with OpenTelemetry/Prometheus/logging/alerts, and enforce multi-tenant data isolation, security, and auditability end to end.

Job requirements:

• 7+ years of backend engineering experience with strong expertise in TypeScript and Node.js
• Experience as a technical lead for a backend or platform domain, with ownership of architecture, technical direction, and mentoring
• Strong experience building ingestion or unstructured data pipelines, ideally involving document parsing across formats such as PDF, Office documents, HTML, or email
• Strong database, indexing, and retrieval experience across PostgreSQL, Elasticsearch, Qdrant, or similar systems
• Experience improving retrieval quality in production using embeddings, vector search, or RAG-style retrieval systems
• System design maturity: you can design for scale, failure handling, service boundaries, and pragmatic trade-offs under real constraints
• Multi-tenant SaaS experience: you understand data isolation, tenant-scoped processing, and enterprise security requirements
