#Part-time ~15 hours / week to start

#Compensation: Future Compensation

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 now 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. You’ll oversee platform scaling, AI system deployment, and modular integration across real-time scoring, vendor ecosystems, and luxury services. Your strategic and technical leadership will help bring it from working product to intelligent, trusted infrastructure.

Responsibilities include:

1. Scaling real-time web platforms (startup or freelance accepted)
2. Familiarity with big data architecture (structured / unstructured pipelines, streaming systems)
3. Working with technologies such as JS, Next.js, React, PostgreSQL, MongoDB, Redis
4. Ensuring excellent communication, documentation, and remote team collaboration

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
• Managing real-time ingestion of user, transaction, and service data
• Optimizing infrastructure for performance, security, and data flow integrity

Compensation Structure:

• Transition 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)
• 1–2 developers onboarded and agile system in place

This is your chance to merge machine learning, community validation, and luxury UX. We’re creating infrastructure for ethical, data-transparent, reputation-driven resale—and your work will be core to that mission. As the company grows and raises funding, your role and rewards grow with it—on a schedule that’s transparent and earned.

Send us your CV or LinkedIn and a short note on why you are the right fit for Mark3t at our email. Within the first month, if you proceed to the next step, we’ll schedule a chat with our founder Nicole and interim CTO, Thomas (CET time).
