The Paradigm Shift Big Tech wants enterprise intelligence in the cloud. Enterprises want absolute architectural control. Chordian.ai is a Swiss-born, zero-trust sovereign memory layer built entirely for the enterprise agentic age. We capture, govern, and make an organization's institutional knowledge instantly retrievable—without that data ever leaving the boundaries of their air-gapped infrastructure. We provide a strict, verifiable full-offline guarantee for the entire data-refining pipeline. Backed by live production systems and an elite advisor network, we are looking for a technical force to step into a fully operational product, take radical ownership, and co-steer Chordian's roadmap. Your Strategic & Technical Mission Algorithmic Optimization: Advance our core indexing engine to process, query, and structure high-velocity enterprise data streams across massive, disparate datasets. System Orchestration: Evolve our ontology engine to seamlessly unify multi-modal schemas and databases into a single, high-performance semantic retrieval layer (<400ms multi-hop graph queries). Deterministic State Control: Refine write-time conflict resolution protocols to handle and resolve data contradictions locally, prior to any model inference. Strategic Leadership: Co-author the technical roadmap, vigorously defend our security and architecture moats for tier-1 institutional clients, and scale a elite engineering culture. What You Bring to the Seat Academic Edge: Late-stage student (4th year BSc, MSc) or PhD candidate/graduate from ETH Zurich in Computer Science or a deeply quantitative field. Systems Mindset: Deep command of isolated network infrastructure, air-gapped storage paradigms, and heavy hardware/VRAM resource optimization. Data Structure Rigor: Practical or theoretical fluency in complex graph topologies, custom vector spaces, spatial indexing, and deterministic pipelines. Execution Drive: The leadership maturity to guide technical execution and ship production-grade code into high-stakes environments. What We Offer Significant founder-level equity stake aligned with operational ownership. The opportunity to build un-wrappable, foundational sovereign architecture—no shallow wrapper APIs. Direct integration into the Swiss deep-tech ecosystem alongside top-tier advisors. #Systems & Lead R&D Architect — Sovereign Enterprise Memory (Co-Founder Track)
