This is a rare chance to build a product that’s loved and remembered.

The Role

We’re looking for a Senior NLP Engineer to help evolve and scale the Kyo AI Engine. This is an applied role, not a research one as you’ll be working on production-grade NLP systems that power live customer insights for global brands.

You’ll take large, messy, multilingual data and make it usable, accurate, and fast — bringing intelligence into where people work (Slack, Zendesk, Teams, and more).

What You’ll Do

• Design, train, and deploy custom NLP / LLM pipelines for text understanding, classification, summarisation, clustering, and semantic search.
• Build intelligent data enrichment pipelines that improve model precision over time.
• Ensure our models are trustworthy, explainable, and measurable — balancing innovation with reliability.
• Contribute to AI Ops, eval and observability frameworks to continuously monitor model drift and quality.
