Description du poste

Location: Remote / Flexible (CET preferred) - Ideally Paris, FR, or can travel within the EU for conferences/meetings

Part-time ~15 hours/week to start

Company: ai is a Paris-based startup redefining luxury resale through trust, technology, and community. We are building a blockchain-authenticated, AI-powered marketplace where trust is measurable, reputations are rewarded, and luxury goods carry a verified digital identity. The platform integrates real-time scoring algorithms, AI-driven insights, and blockchain-based authentication to enable high-value transactions between buyers, sellers, and service vendors—securely and transparently.

We’re seeking a growth-phase technical leader to evolve our architecture and help scale the platform through its next iterations and beyond. As CTO, you’ll partner closely with the founder to architect the next stage of Mark3t’s tech vision. Your responsibilities include overseeing platform scaling, AI system deployment, and modular integration across real-time scoring, vendor ecosystems, and luxury services. Your strategic and technical leadership will help transition from a working product to an intelligent, trusted infrastructure.

Requirements:

• Proven experience scaling real-time web platforms (startup or freelance accepted)
• Familiarity with big data architecture (structured/unstructured pipelines, streaming systems)
• Experience with JS, Next.js, React, PostgreSQL, MongoDB, Redis
• Excellent communication, documentation, and remote team collaboration skills

Bonus Skills:

• Exposure to ZKPs, digital identity, or decentralized storage (IPFS)
• Experience working with luxury, fashion, or high-net-worth UX
• Interest in blockchain, smart contracts, token rewards, or decentralized identity
• Ability to manage real-time ingestion of user, transaction, and service data
• Optimize infrastructure for performance, security, and data flow integrity

Compensation Structure:

• Future compensation, transitioning to a paid CTO or Tech Lead role post-funding (target: post-beta/early traction)
• Trust system + authentication flows integrated (blockchain)
• Revenue stream tested (subscription, commission, or service tier)
• Onboard 1–2 developers and establish an agile system

This role offers the opportunity to help define the backbone of trust for the next generation of luxury commerce by merging machine learning, community validation, and luxury UX. As the company grows and raises funding, your role and rewards will grow with it, on a transparent and earned schedule. Send us your CV or LinkedIn profile and a brief note on why you are the right fit for Mark3t to our email. Within the first 1-3 weeks, if selected, you’ll have a chat with our founder Nicole and interim CTO Thomas (CET time).
