• Train, fine-tune, and evaluate large-language / foundation models, while also applying parameter-efficient techniques, reinforcement learning, and prompt engineering approaches
• Build and enhance memory and context management systems: manage short- and long-term context, embeddings, and retrieval pipelines so Maia can access relevant information effectively
• Integrate structured knowledge sources such as knowledge graphs and ontologies to improve consistency, reasoning, and reduce hallucinations
• Develop capabilities for ingesting and processing multiple unstructured and multi-format data types (text, audio, etc.), designing pipelines for parsing, embedding, indexing, and retrieval
• Optimise inference and system performance: reduce latency, increase throughput, design efficient prompt pipelines, and engineer for cost-effective scaling
• Define and implement monitoring and evaluation frameworks: track metrics such as accuracy, drift, error rates, and user satisfaction; set up feedback loops to ensure robustness and reliability
• Collaborate with engineers, product managers, and UX teams to turn experimental techniques into stable, scalable features that deliver measurable value
• Stay hands-on: write code, prototype solutions, and contribute directly to implementation (with some work in Java where relevant)
  

• Deep AI Expertise: Proven experience working with large language / foundation models, including training, tuning, and applying modern GenAI techniques such as reinforcement learning, memory and context systems, retrieval augmentation, structured knowledge integration, optimisation, and evaluation
• Academic Rigor: Master’s degree in a relevant field required; PhD preferred
• Programming Ability: Strong coding skills in Java are required
• Product Delivery Experience: Track record of delivering software features or products in a collaborative environment, ideally within a product-led organisation
• Curiosity & Drive: Passion for emerging AI technologies, with the ability to critically evaluate new research and translate it into practice
• Collaborative Mindset: Comfortable working cross-functionally to move from prototypes to production-ready features
