Summary

Scandit in Zurich is looking for a Senior Machine Learning Engineer to build on-device face recognition and matching models for high-assurance identity verification in regulated industries.

Job Description

Scandit automates workflows across industries with cutting-edge technology. In our ID Capture team in Zurich, we build the machine learning behind high-assurance identity verification for banks, fintechs and regulated businesses. As a Senior Machine Learning Engineer, you will own the face recognition and face matching models that run fully on device, on the phones our users already have, with no cloud round-trip.

• Design, train and evaluate models for face detection, face recognition and 1:1 face matching against ID document portraits
• Support the team's work on liveness and presentation attack detection (PAD) against spoofs, replays and deepfakes
• Define quality metrics, benchmarks and test sets that meet high-assurance and regulatory expectations
• Own the full loop: data collection and labelling strategy, prototyping, training, evaluation, debugging and model integration
• Optimise models for on-device inference with our C++ engineers (quantisation, pruning, mobile runtimes)
• Track research in biometrics and face anti-spoofing, and turn it into product direction
• Mentor engineers on ML practice

• 5+ years as an ML engineer, with production models shipped to real users
• Hands-on experience with biometrics: face recognition, face verification, liveness or PAD
• Fluent in Python and at least one deep learning framework (PyTorch preferred)
• Strong grasp of evaluation for security-sensitive systems: FAR/FRR, bias and fairness across demographics, adversarial robustness
• Clear communicator who works well across disciplines
• Eligible to work in the hiring location

• A highly skilled team and a fun environment where you can put your enthusiasm for cutting-edge technologies to use
• Flexible, office, hybrid or home working
• People-first culture with global team outings and Micro Adventures
• An attractive individual equity plan in a high-growth company
• Excellent office infrastructure optimised for hybrid working in Zurich
