About Concurrences
Mission: "Connecting Antitrust People." The integral platform for competition law — 20+ years, 150+ countries, ~50,000 professionals. Lawyers, economists, judges, regulators, academics: all shaping competition policy. We started as a challenger taking on established players. That DNA hasn't changed — now we're building with generative AI.
What drives us: Excellence — scientific rigor and editorial quality in everything we publish. Innovation as a driving force — pioneering new formats, anticipating industry trends, now building with generative AI. And a general community connected through high-level dialogue and best practices shared across borders.
The Role
You own the RAG and inference infrastructure for the world's first production AI built for antitrust law. October 2026 launch, 50+ competition authorities worldwide. You're not junior support — you own systems end-to-end: retrieval pipelines, vector databases, inference orchestration, API design. You make architecture decisions. You ship every week.
Why this matters:



Concurrences.com is the definitive antitrust platform (20 years, 100K+ articles). Now we're turning 330–430K legal documents into a production-grade agentic research engine.
What You'll Build
- RAG pipelines: chunking, embedding strategies, retrieval optimization (BM25 + semantic + reranking), latency tuning
- Python + FastAPI APIs: exposing search, retrieval, agentic workflows to Claude, ChatGPT, enterprise copilots
- Weaviate: schema design, indexing strategy, query optimization, cost-per-query tuning
- LLM integration: managing context, prompt templates, cost/latency trade-offs
- Agentic systems: CrewAI, LangGraph, or LlamaIndex for multi-step research flows
- Infrastructure: CI/CD with Pulumi/Terraform, monitoring, observability

A Typical Week
- Monday: Bug in chunking pipeline. Root cause, fix, PR, test. Partner with LLM engineer on retrieval validation.
- Tuesday: Customer request: search across EU + US jurisdictions. Redesign
