Full Job Description
The Opportunity:

We are seeking a Senior Data Scientist to take a hands-on, delivery-focused role applying prompt engineering, artificial intelligence (AI), machine learning (ML), and process automation to complex, real-world data problems. This role is vendor-neutral and emphasizes designing AI-driven workflows, providing structured context to large language models (LLMs), and driving measurable efficiency gains.

While HKA currently uses Jylo as an embedded AI tool, prior experience with this platform is not required and can be learned quickly. Success in this role depends on strong fundamentals in applied data science and the ability to translate legal, technical, and commercial context into effective AI-enabled solutions - rather than deep expertise in any single product or platform.
Responsibilities:

Prompt Engineering & LLM Design
  • Lead prompt engineering as a core capability within HKA
  • Design, test, and refine structured prompt playbooks aligned to litigation, arbitration, and investigative use cases
  • Provide legal, technical, and commercial context to LLMs to improve accuracy, relevance, and defensibility of outputs

AI-Driven Document Review
  • Apply AI and ML techniques to large-scale document review in construction disputes, fraud investigations, and arbitration matters
  • Analyze document populations typically ranging from 150,000 to 250,000+ records
  • Reduce large datasets to high-value, defensible subsets for Partner and expert review

Driving Efficiency in Data Cleansing
  • Design and implement AI-enabled data cleansing, normalization, and de-duplication pipelines
  • Improve speed and quality of relevance classification and issue tagging
  • Reduce manual effort through intelligent automation while maintaining auditability and quality controls

Automation & Process Improvement
  • Identify manual, repeatable processes suitable for automation across delivery teams
  • Support opportunity-to-cash and delivery workflows through RPA and process automation initiatives
  • Rapidly prototype and iterate on automation solutions in a developing, evolving environment

Tooling Flexibility & Innovation
  • Operate with a tool-agnostic mindset, focusing on fit-for-purpose solutions rather than specific vendors
  • Evaluate and recommend new AI, ML, or automation tools where they add clear value
  • Contribute to shaping HKA's broader AI, data, and automation roadmap
Required Skills and Experience:
  • 5+ years of hands-on experience in applied data science, machine learning, or advanced analytics roles, with direct responsibility for delivery (not research-only)
  • Experience in Professional Services consulting, expert advisory, forensic, legal, or investigative environments, where outputs must be accurate, explainable, and defensible
  • Proven experience working with large, unstructured, text-heavy datasets (e.g., document review, investigations, disputes, or similar use cases)
  • Expertise with Jylo strongly preferred, not required.
  • Practical experience applying LLMs, NLP, or text analytics to real-world workflows such as document classification, relevance review, summarization, or issue tagging
  • Hands-on experience designing and refining automation or ML pipelines, from prototype through production use
  • Strong Python-based data science skills with the ability to work quickly, iterate, and troubleshoot independently
  • A pragmatic, delivery-focused mindset with the ability to translate ambiguous legal or business problems into structured, AI-enabled solutions
