Job Description

Senior Computer Vision Engineer developing deepfake and liveness detection models with a cross-functional R&D team in Hungary. Working on a large-scale facial and video database to ensure system integrity and authenticity.

Responsibilities:

  • Build and improve deepfake and liveness detection models using CNNs, attention layers and vision-language models.
  • Design, train and evaluate models end to end, from preparing data to checking results, following good engineering practices.
  • Fine-tune vision-language models using efficient methods such as LoRA.
  • Make models smaller and faster for both cloud and on-device / mobile use.
  • Build and maintain training and deployment pipelines to get models into production on AWS (e.g. EC2, Athena).
  • Use AI-assisted coding tools such as Claude Code to speed up experimentation and prototyping.
  • Share progress clearly with technical and non-technical colleagues, and own independent research & development initiatives.

Requirements:

  • A BSc, MSc or Ph.D. in engineering, computer science or a related field.
  • At least 5 years of professional experience developing and deploying deep learning and computer vision models.
  • Strong grasp of the end-to-end ML workflow: preparing data, training models and evaluating results.
  • Solid grounding in modern neural network architectures, including convolutional networks and attention mechanisms.
  • Working understanding of large language models (LLMs), vision-language models (VLMs) and adaptation techniques.
  • Experience working in agile environments, with strong analytical and problem-solving skills.
  • Experience with deepfake detection, face anti-spoofing / liveness, biometric security or media forensics is a strong plus.
  • Experience leading or mentoring machine learning engineers is a strong plus.
  • Expert-level Python, with proven experience building deep learning models in production.
  • Familiarity with C++ is a plus.
  • Professional experience with modern deep learning frameworks such as PyTorch, TensorFlow or JAX.
  • Hands-on experience deploying and optimising models on AWS (e.g. EC2, Athena) and related MLOps services. (MLFlow etc)
  • Experience optimising neural networks for deployment, including model compression, quantisation and runtime optimisation.

Benefits:

  • Unlimited paid holidays
  • Life insurance and 100% paid sick leave
  • Working from home setup
  • Innovative employee recognition and reward system, Bonusly
  • Strong benefit package including subsidized gym membership / sport allowance, online and offline team-building events, flexible working hours
