About Haast

We're not just talking about AI - we're building one of the first enterprise-grade LLM implementations that delivers real, measurable value to compliance and legal teams today.

Over the past two years, we've transformed compliance from a painful checkbox exercise into a smooth, intelligent process. Our AI-powered platform helps, compliance, and marketing teams revolutionise their operations with 80% faster reviews and 4x productivity boosts, freeing them to focus on work that matters.

As the regtech industry rockets toward a $50 billion future, we're proudly leading this shift on the global stage.

The Role

  • Optimize & Scale: Lead the optimization of retrieval strategies and pipelines for high-recall compliance detection.
  • Benchmark & Evaluate: Develop evaluation systems, drive continuous tuning, and set performance standards.
  • Partner & Deliver: Collaborate with product and engineering to deliver new ML features end to end.
What you'll bring

Must Have:

  • Proven experience in ML or search engineering in production
  • Proficiency in Python and writing clean, maintainable code
  • Hands-on experience with LLMs, RAG architectures, and real-time inference systems
  • Experience designing, deploying, and maintaining ML systems in production
  • Experience working across back-end systems and search infrastructure
