Junior AI/ML Engineer

Hey there!👋

At Fourthline, our mission is to fight financial crime. We help protect the global financial system by verifying millions of identities for banks, neobanks, online brokers, crypto exchanges, or insurers like N26, Trade Republic, flatexDEGIRO, National Nederlanden, Qonto, Shine, Solarisbank, and more.

Having started our journey in January 2018 only, we’re incredibly proud to count around 250 employees between our Amsterdam and Barcelona offices with over 50 nationalities.

Your Mission at Fourthline

Join our mission to prevent financial crime by developing best-in-class AI. You’ll work alongside an exceptional and talented team, dedicated to making our onboarding AI the most reliable in the industry through cutting-edge technology. We’re seeking a passionate and high-performing individual who is eager to contribute to our efforts. In return, you’ll receive strong support from our collaborative AI team and mentorship from one of our senior AI engineers.

As a Junior Machine Learning Engineer, in the first six months your mission will be:

• Perform penetration testing on our mobile SDKs and AI systems by creating and injecting deepfake videos into our identity verification flow.
• Conduct research on the latest advancements in deepfake creation, mapping out current methods and assessing their levels of sophistication.
• Evaluate the risks associated with deepfake attacks.

After completion, you will shift your focus to these tasks:

• Support our AI team by building new models to classify user authenticity using RGB, depth, accelerometer, gyroscopic data, and more.
• Create prototypes and products using Python, TensorFlow, OpenCV, and more. You can add new tools if they suit our goals!
• Validate your experiments through rigorous testing on our extensive in-house dataset.
• Write code that adheres to our internal standards for style, maintainability, and best practices for a large-scale machine-learning environment. Maintain and advocate for these standards through code review.
• Contribute to thorough documentation—crucial for ensuring success and minimizing questions.
• Employ both technical and soft skills to address challenges, recognizing that solutions often require a blend of technology-based and people-based strategies. We work closely with our AI DevOps team, Fraud team, and Mobile teams to ensure your models add value across the board.
• Engage in continuous learning. We conduct monthly knowledge-sharing sessions to stay up-to-date on the latest research, new tech and fundamental concepts in computer science.
