Sydney, New South Wales, Australia beBeeCompliance Full time $90,000 - $190,000
Job Opportunity

Airtree is advertising this role on behalf of Haast. Your application will be reviewed by a team member of Haast, not Airtree.

Haast is building one of the first enterprise-grade LLM implementations that delivers real, measurable value to compliance and legal teams today.

We are revolutionising operations with 80% faster reviews and 4x productivity boosts in the regtech industry which rockets toward a $50 billion future.

Think about it: Design has Canva. Projects have Trello. Now, Compliance has Haast.

The Role

You'll design and implement hybrid recall methods that blend cutting-edge search databases with large language models.

You'll play a key role in shaping how our platform detects compliance risks in real time, designing intelligent, scalable systems that power critical decision-making for enterprise teams.

This is an ideal role for someone who wants to take ownership of high-impact systems in a product-led, AI-first company and help define how cutting-edge models are applied to real business problems.

Impact you'll make

  • Own the design and implementation of hybrid search methods combining vector databases and LLMs
  • Lead the optimisation of LLM pipelines and retrieval strategies for high-recall compliance detection
  • Architect and maintain search infrastructure for scalable, low-latency query handling
  • Design benchmarking systems and drive continuous model evaluation and tuning
  • Work across structured and unstructured data to surface hidden compliance risk signals
  • Partner with product and engineering to bring new ML features to life, end to end

What You'll Bring

Must Have:

  • Deep expertise in machine learning and/or search engineering, especially in production environments
  • 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
  • Experience building NLP evaluation systems

Bonus points if you have:

  • Experience with search technologies (Vespa, OpenSearch)
  • FastAPI framework knowledge
  • Startup or high-growth environment experience
  • Research background in ML or search
  • Experience with DevOps and CI/CD tools

Growth and Impact:

  • Leading the evolution from dull, traditional SaaS to AI-powered workflows
  • Build enterprise-grade AI technology that major institutions actually trust and love
  • Empowering humans to focus on strategic work they love by eliminating tedious compliance reviews
  • Creating technology that builds customer trust and protects consumer rights

Benefits and Culture:

  • Remote work available for exceptional candidates, preferably Sydney-based with flexible work arrangements
  • Competitive salary and equity - we believe in sharing the success
  • Rapid career growth - high performers get real opportunities
  • Collaborative, engineering-driven culture focused on learning and development
