Company mission
To empower data teams to build and manage pipelines faster for AI and analytics - at scale.
Role
Who you are
- The ideal candidate brings strong Java proficiency and a deep interest in Generative AI technology
- If you're driven by impact, innovation, and the chance to work at the frontier of AI in a product-led organisation, this is the opportunity for you
- 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
What the job involves
- We're hiring a Software Engineer to drive our GenAI initiatives
- At Matillion, we’re on a mission to eliminate friction in data engineering and supercharge productivity through the power of AI
- As part of the Product organisation, our Data Science team is laser-focused on two things: pioneering how artificial intelligence and machine learning are woven into our products, and understanding how our customers use those products to drive continuous innovation
- This Software Engineer role sits at the heart of that mission
- You’ll be hands-on in developing, optimising, and experimenting with advanced models—helping to shape how Maia and our AI systems evolve end-to-end
- From reinforcement learning to context and memory, from structured knowledge to performance optimisation, you’ll explore new approaches and translate them into product-ready features that deliver real value to our users
- 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)
Application process
- We are keen to hear from prospective Matillioners, so even if you don't feel you match all the criteria please apply and a member of our Talent Acquisition team will be in touch
