About Us

We’re a startup that lives and breathes technology. We are based in Barcelona, Spain. We create, experiment, and build to contribute making the world a bit better through the tools we can use the best. We leverage innovative technologies (web3, artificial intelligence) to deliver business value to financial institutions.

The Opportunity

This is an opportunity to join an early startup and work directly with the founder on cutting-edge technology. You’ll contribute to technical decisions, gain exposure to both the business and technical sides of a startup, and grow faster than you would anywhere else.

Your first project will be our an AI-powered monitoring system for on-chain activity, combining blockchain infrastructure with anomaly detection algorithms to help make web3 safer and more transparent.

What You’ll Do

• Build full-stack applications that bridge blockchain data with state of the art AI/ML models
• Develop and implement anomaly detection systems for on-chain activity monitoring
• Work with blockchain infrastructure to interact with various chains, protocols, and dApps
• Iterate rapidly based on user feedback and real-world data
• Take ownership of features from conception to deployment
• Contribute shaping our technical stack, architecture, and engineering culture

Who You Are

• Recent or completing CS graduate or equivalent, with a good foundation in computer science or computer engineering
• Curious and crafty—you love tinkering, building side projects, and figuring out how things work
• Genuinely excited about web3 and AI (the tech, not the hype)
• Comfortable developing across the full stack: frontend, backend, and everything in between
• Someone who feels stuck if not growing or learning something new
• A strong problem-solver who can work independently but knows when to ask for help
• Fluent in English (spoken and written) and eligible to work in Spain

Nice to Have

• Personal projects or contributions to open source
• Familiarity with blockchain (smart contracts, consensus mechanisms, DeFi)
• Experience with Python, Go, JavaScript/TypeScript
• Interest related to cryptography, machine learning, or data science
• Hackathon or competitive programming experience

What We Offer

• Fast growth: Learn more in one year than most people do in three
• Direct mentorship: Work closely with the founder with zero bureaucracy
• Real impact: Your code will go into production and get in the hands of real users
• Flexibility: Remote work anywhere in Spain, flexible hours
• Cutting-edge tech: Work at the frontier of web3 and AI and help push what’s possible

Location

Remote, within Spain, or hybrid (Barcelona)
