AI Researcher

The role

You will train, fine-tune, and improve proprietary speech-to-text models across 24+ European languages. You will build experimentation platforms, design and run experiments, and own the full loop from experiment to deployment using a GPU cluster.

What you will do

• Train, fine-tune, and improve proprietary speech-to-text models across 24+ European languages
• Build and maintain a stable, reproducible experimentation platform
• Design and run experiments regarding model architecture, training recipes, data mixes, and domain adaptation strategies
• Analyse results rigorously, document findings, and ship what works into production
• Train and run inference on Reson8's own GPU cluster in NL datacenters
• Evaluate new architectures, training techniques, and tooling
• Identify research opportunities, run experiments, build infrastructure, and validate results in production

Required qualifications

• Strong background in machine learning
• Hands-on experience training and evaluating deep learning models
• Experience building or contributing to experimentation infrastructure
• Comfort reading research papers and translating ideas into working code

Nice to have

• Proficiency in Python and PyTorch
• Speech recognition architectures (CTC, RNN-T, encoder-decoder ASR, Whisper-style models)
• NVIDIA tooling: NeMo, TensorRT
• Distributed training or multi-GPU workflows
• Rust
• Kubernetes or container orchestration
• Language-specific challenges in European languages (morphology, code-switching, diacritics)

Benefits

• Salary competitive with the top of the market
• Meaningful equity as an early employee
• 25 days of vacation
