• Establishing, enforcing, and continuously evolving best practices, standards, and procedures within the NLP and generative AI engineering team.

• Providing technical mentorship, guidance, and leadership to engineers and junior team members, fostering professional growth and technical excellence.

Requirements

• Excellent written and verbal communication skills in native Dutch and English (French is a plus).

• Advanced degree (Master's or PhD) in Computer Science, Natural Language Processing, Artificial Intelligence, Machine Learning, or a related field.

• 5+ years of experience with implementing NLP and generative AI models, with deep expertise in transformer architectures, language models, and embeddings.

• Demonstrated leadership experience in technical AI/ML projects, including team mentoring and project management.

• Expert-level proficiency in Python and extensive experience with machine learning libraries (PyTorch, TensorFlow, Hugging Face transformers). Experience in Typescript is a plus

• Strong understanding of natural language processing techniques, including text classification, named entity recognition, sentiment analysis, and language generation.

• Proven experience with large language model fine-tuning, prompt engineering, and evaluation methodologies.

• Solid knowledge of data structures, algorithms, and software engineering principles.

• Experience with cloud-based platforms and services such as Azure, with a focus on scalable AI solutions.

• Familiarity with software development methodologies such as Agile or Scrum.

• Exceptional problem-solving skills with the ability to think critically and creatively to develop innovative AI solutions.

• Strong communication and presentation skills with the ability to effectively convey complex technical concepts to diverse audiences.

The following experiences are a plus:

• Open-source contributions to Generative AI or NLP projects

• Active GitHub repositories demonstrating advanced NLP implementations or prior engagements in relevant Kaggle competitions

• Proven track record of designing and deploying scalable language models in production environments

• Publications in relevant NLP/AI/ML conferences and journals (ACL, EMNLP, NeurIPS, ICML, etc.)

• Experience in one of our focus domains: Data Quality, Retail, Manufacturing, Finance

• Knowledge of multilingual NLP and cross-lingual transfer learning

We offer:

• A rewarding salary package that includes additional perks like a company car and fuel card or a mobility budget, comprehensive hospitalisation, group insurance, and a top-tier laptop and smartphone

• A company culture that stimulates both individual and team development, fostering professional growth and leadership opportunities

• Regular team-building activities and gatherings, which provide great opportunities to unwind and engage with our vibrant team initiatives

• A flexible hybrid working policy to choose where, how, and when you want to work

• Opportunities to represent Faktion at industry conferences and events: you'll be the face of Faktion's GenAI Engineering initiatives

At Faktion we build AI, and we use it thoughtfully in our own processes too. During your application, AI tools may help us with practical steps, like checking that your documents came through complete. They never decide who moves forward: every application is read by a real person on our team, and every decision is made by a human. Curious how this works, or how your data is handled? Just ask, we're happy to explain.
