About the Role

Design and deliver cutting-edge GenAI solutions for major Australian organisations. This hands-on technical role involves owning production-grade AI applications from design to client handover, blending deep technical expertise with a consultative approach. You will collaborate with data scientists, engineers, and client teams to solve complex business problems using LLMs, machine learning, and cloud technologies.

Responsibilities

  • Design and build production-grade GenAI and LLM applications using Python and modern AI frameworks (e.g. LangChain, LangGraph)
  • Architect and implement AI solutions on major cloud platforms (AWS, Azure, or GCP) using containerisation and cloud-native practices
  • Make informed technical decisions on AI approaches — knowing when to use classical ML, LLM prompts, workflows, or agents
  • Design evaluation frameworks and observability metrics to ensure solution quality and performance
  • Develop APIs and build data pipelines using SQL, DBT, and orchestration tools
  • Collaborate with clients and domain experts to understand problems, validate approaches, and translate technical concepts for non-technical stakeholders
  • Conduct code reviews, mentor junior team members, and contribute to team technical standards
  • Support business development through technical scoping, solution design, and proposal contributions
  • Identify and communicate technical risks and trade-offs clearly and proactively

Requirements

  • 5+ years of experience in data science, AI/ML development, or technical consulting
  • Proven track record of delivering production-grade AI/ML solutions end-to-end
  • Strong Python programming skills with solid software engineering practices — testing, code quality, and version control
  • Practical experience building GenAI/LLM applications using frameworks like LangChain, LangGraph, or equivalent
  • Hands-on experience with at least one major cloud platform (AWS, Azure, or GCP) and containerisation (Docker)
  • Solid understanding of ML/AI fundamentals including how LLMs work, transformer architectures, and when to apply different approaches
  • Working knowledge of SQL and data pipeline concepts
  • Strong communicator — able to explain complex technical concepts clearly to non-technical audiences
