Senior AI Engineer (Sydney-Based)

We're on a mission to be a Force For Good, through our People, Products and Purpose at Nuix. This extends to our People. We're fiercely passionate, love working at pace, thrive in ambiguity, live, and breathe outside of the box, and above all are good humans. We're determined to make a positive difference in the world, whether through our solutions which help the top companies, governments and agencies find the truth and combat illegal activities, or through our people who care about contributing and giving back both within, and outside, of Nuix. We are a Force For Good. We're selective about who comes on board, and you should be too. But if the above sounds like a match, get in touch today and get ready for the possibility of starting a once-in-a-career journey.

Role Overview:

Nuix is building a new AI engineering team in Sydney. The team owns Enrich, our AI data enrichment product that finds, identifies and classifies information in unstructured documents. It will also build new AI and agentic capability into the Nuix Neo platform, helping investigators, legal teams and regulators find what matters in very large volumes of data, where accuracy and auditability count.

As a Senior Software Engineer you will be a strong individual contributor who takes features from design to done. You’ll write backend code in Java and Spring Boot, work with Python and React/TypeScript where needed, and help raise the standard on security, performance and DevOps. You’ll also help the team’s more junior engineers grow.

Our products ship as SaaS and on-premises, so you’ll build software that runs in customer-managed environments as well as in the cloud.

Location:

This position will be based in our Sydney office. The candidate is required to attend the office a minimum of 3 days per week but may voluntarily elect to work either remotely or from the Sydney office for the remaining 2 days of the week. (We welcome candidates who are based in other locations in Australia and are willing to relocate to Sydney)

Key Responsibilities

• Own significant features and epics end to end across Enrich and our agentic work, from design through build, testing and release.
• Improve and extend an established machine learning product with pragmatic changes, rather than unnecessary rewrites.
• Help shape how we design, evaluate and ship AI agents and LLM-backed features in the platform.
• Raise the standard on security, performance and DevOps, including secure-by-design code review on complex pull requests.
• Contribute to architecture discussions by asking questions, challenging approaches and helping define the target state.
• Work closely with product, architecture and data science colleagues, across time zones.
• Mentor mid-level, associate and graduate engineers.

Skills, Knowledge and Expertise

• More than 7+ years of Software Engineering experience, with a record of delivering complex work end to end.
• Strong hands-on backend engineering (bonus points for Java, Springboot). You write code every week and can discuss concurrency, failure handling, performance and trade-offs in work you’ve done.
• Experience shipping AI-backed software, or a clear wish to build it with the support of a team that has. We pair skills across the team.
• You use AI tools in your own engineering workflow, can check AI-generated code, and can speak confidently about what works and what doesn’t.
• Good engineering judgement, clear communication, and a willingness to mentor in a distributed team.
• A degree in Computer Science, Engineering or a related field, or equivalent experience.

Desired Expertise:

• Both agentic and classic machine learning experience in a product, including RAG, LLM evaluation and MCP.
• Python in production, and NLP, search (Elasticsearch, OpenSearch or Lucene) or document intelligence.
• Kafka or other event-driven and data pipeline experience.
• Kubernetes, Docker and AWS, plus CI/CD (for example Jenkins) and a strong automated testing practice.
• React and TypeScript for full-stack work.
