Founding AI Product Engineer – Agentic Systems & Knowledge Graphs

Founding AI Product Engineer – Agentic Systems & Knowledge Graphs
ChordianAI · Berlin, London or Warsaw (Remote/Hybrid) · Full-time (100%)
Companies want AI that knows their markets, their clients and their own business, without giving up control of their data.
ChordianAI is Data Intelligence & Zero Trust Infrastructure for AI. Our intelligence engines search, research, crawl, build lists and monitor the web and licensed sources. That intelligence is joined with a company's own knowledge and fed into Knowledge Twins: one subject per twin (a client, a market, a deal, a supplier, a regulation), always current and always sourced. Every value is classified and protected before it is stored or reaches any model, and every access is audited. It runs where the customer decides: our cloud in the EU or US, the customer's own cloud, or on premises and air-gapped.
People use it through the app, Slack and voice. Agents use it through MCP and our REST API.
We are looking for a founding team member who builds agentic systems, not slides about them, and who will own how intelligence reaches people and agents through Knowledge Twins.
WHAT YOU'LL DO
- Design and build Knowledge Twins and the agentic workflows that run on them, end to end
- Own the Twin Library and Twin Console: which twins exist, how they are configured, how customers see sources, health and usage
- Turn real customer questions into repeatable agentic workflows: market screening, pricing intelligence, counterparty and supplier monitoring
- Shape how our intelligence, memory and graph layer serve agents: retrieval, Entity Coherence, conflict handling, sourcing
- Make Zero Trust visible in the product: where data runs, how it is protected, who accessed what
- Work with enterprise customers and with our engineering and commercial teams
MUST HAVE
- You have built agents and fully agentic systems, and you can show at least one end to end (repo, live demo or recorded walkthrough)
- Deep, hands-on knowledge of knowledge graphs, GraphRAG and retrieval architectures, and their trade-offs against vector-only approaches
- Strong command of the agentic stack: tool use, MCP, multi-agent orchestration, memory, evaluation, LLM providers and private models
- You know the data intelligence and agent infrastructure ecosystem inside out, including the leading venture-funded players, and can explain where each one wins and loses
- Product judgment: you obsess over simplicity, and a user should understand what you build in seconds
NICE TO HAVE
- Enterprise AI deployments, ideally in regulated industries (finance, legal, insurance, energy, consulting)
- Background in security, data governance or sovereign cloud
- Experience with web data, crawling or enrichment pipelines
WHAT WE OFFER
- A founding-team role with real ownership of a core product pillar
- Meaningful equity plus a competitive salary
- Direct work with the CEO and leadership team
- Your choice of base: Berlin, London or Warsaw, remote or hybrid
- A small, senior team building foundational infrastructure for AI
HOW TO APPLY
Send us two things:
1. A link to an agentic system you built end to end, with two lines on what it does and how it is built
2. Three sentences on the players in agent memory, GraphRAG and data intelligence you rate most, and why
Applications without a showcase will not be considered.
