AI Researcher

• Strong background in machine learning, with hands-on experience training and evaluating deep learning models (ideally in speech, NLP, or sequence-to-sequence domains).
• Proficiency in Python and PyTorch (strongly preferred). You've actually trained models, not just fine-tuned notebooks.
• Experience building or contributing to experimentation infrastructure—experiment tracking, reproducible training pipelines, evaluation frameworks, or similar tooling.
• Comfort reading research papers and translating ideas into working code.
• Bonus experience with:
• Speech recognition architectures (CTC, RNN-T, encoder-decoder ASR, Whisper-style models).
• NVIDIA tooling: NeMo, TensorRT.
• Distributed training or multi-GPU workflows.
• Rust (we use it in performance-critical parts of our stack).
• Kubernetes or container orchestration.
• Language-specific challenges in European languages (morphology, code-switching, diacritics).

• Salary competitive with the top of the market
• Meaningful equity as an early employee with real influence over direction and culture.
• 25 days of vacation.

We're backed by Europe's best investors, and we're here to prove that fundamental AI infrastructure can be built on this continent, not just consumed from the US. If that matters to you, let's talk.

Amsterdam-based. Office-first, at least 3 days per week.

About Reson8

At Reson8, we're on a mission to become a global leader in accurate, customisable speech-to-text for European languages, so every conversation is captured as it was meant to be.

Unlike generic tools, Reson8 understands domain-specific jargon and adapts to the unique needs of each professional environment. From medical consultations to legal depositions to restaurant operations, Reson8 handles the jargon that generic tools get wrong.

Available in 24 European languages so far, Reson8 is backed by world-class VCs and is committed to building a world where everyone is understood—no matter their language, accent, or jargon.

How we work

• Small, highly technical team where everyone is a shareholder and behaves like an owner.
• No passengers: expectation of high accountability, curiosity, and bias to action.
• High bar for craftsmanship and attention to detail that competitors ignore.
