Technical Co-Founder (CTO)

Reversible tokenization — sensitive data never leaves the EU perimeter. Unlike destructive redaction or contractual "no training" promises, Colchix replaces PII with tokens before any query reaches an external LLM, then re-hydrates the response on return. Full context preserved, zero data exposure. Every interaction is logged on EU-sovereign infrastructure — your data vault stays in Europe, always.

Network proxy deployment — zero changes to employee workflow, no software installation required on individual devices.

Backend/security engineer with experience in proxy infrastructure, API interception, network security, or data tokenization. Go, Rust, or Python at production scale. Comfortable owning architecture end-to-end. EU-based preferred.

Colchix is an AI governance gateway for European enterprises. We sit as a network proxy between employees and external LLMs — detecting shadow AI usage, tokenizing sensitive data before it leaves the EU perimeter, and generating audit evidence for GDPR, AI Act, and NIS2. Validation underway across 5 countries with pilot interest confirmed. Active conversations with angels and pre-seed funds. Founder background: Salesforce EMEA, Deliveroo, Alibaba.

I am based in Dublin but open to relocate or working remotely with frequent co-founder meetings

Europe is mandating AI governance. €4B+ TAM. GDPR, AI Act, NIS2 are forcing every enterprise to act. Build the infrastructure that makes it possible. 50/50. You own the tech, I own the market.

You'll be the first technical hire and co-founder. Own the full architecture from day one — proxy layer, tokenization engine, EU-sovereign logging infrastructure. Work directly with early design partners to shape the product. Pre-seed raise planned for Q3 2026. This is a 0-to-1 role with full technical ownership and a direct path to CTO of a funded company.
