Job description

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.

Role Overview

Join the Apical team in Sydney, the squad that designs, builds and maintains the Nuix Platform and Business APIs and the REST SDK that customers, partners and other Nuix product teams use to drive the Nuix Neo platform. Working closely with the Manager of Engineering, the Nuix Product organisation and the scrum team, you will deliver API capability that is secure, well documented and dependable for everyone downstream of it.

As a mid-level Software Engineer you take ownership of user stories, and increasingly of whole features, from design through to release. You write well tested, well styled code, you keep documentation current, and you are an active voice in the wider engineering conversation: backlog grooming, technical design, CI/CD health and customer facing context. You will work alongside Senior and Principal Software Engineers and the architecture group, with clear room to grow into senior scope.

The professional growth that will be developed from success in this position will be:

• Improved technical skills in API design, platform security and multiple Nuix Products
• Enhanced team, community and communication skills
• Understanding of customer needs, challenges and demonstrable ability to recommend appropriate solutions to end-user requirements

Location

This position is based in our Sydney office. The candidate is required to attend the office a minimum of 3 days per week and may voluntarily elect to work either remotely or from the Sydney office for the remaining 2 days of the week.

Key Responsibilities

Please note that these duties and responsibilities are a guideline and by no means comprehensive. Additional tasks may be added from time to time at the discretion of your Manager / Director.

• Deliver user stories and small features end-to-end, from design through to release, with high quality and minimal rework
• Design, build and maintain secure, scalable REST APIs across the Nuix platform, including request validation, consistent response contracts, versioning and backwards compatibility
• Implement and maintain authentication and authorization flows, including API key issuance and exchange, token-based authentication and scope-based access control
• Keep API documentation current and usable, including OpenAPI/Swagger definitions and developer-facing guides
• Write meaningful unit and integration tests, and hold the team's coverage and quality gates
• Investigate and fix build and test failures in the CI/CD pipeline, and keep deployment paths healthy across cloud and local deployment environments
• Apply secure coding practices and act on findings from static analysis and dependency scanning tooling
• Break work into small, releasable increments so the team can deliver early and deliver often
• Participate in planning, backlog grooming and technical design discussions across multiple products, providing reasonable estimates and flagging risk early
• Collaborate with architects, QA, DevOps and other product teams to ensure consistency, maximise code reuse and achieve seamless integration between projects
• Share knowledge through documentation, demos and enablement material, and support the onboarding of newer team members
• Perform code reviews with teaching intent, explaining the why and not only the what
• Adopt AI coding assistants effectively to accelerate ramp-up in unfamiliar areas and improve design exploration, and share what works with the team
• Provide maintenance support as scheduled during business hours

Skills, Knowledge And Expertise

• Degree in a relevant field such as computer science / engineering, software engineering, machine learning, mathematics or a related quantitative discipline, or equivalent practical experience
• 3-5 years of relevant programming experience
• Demonstrated experience building and maintaining production REST APIs in a service or microservice architecture
• Working proficiency in Java, with willingness to work across the stack. Exposure to Python or TypeScript is welcome
• Practical understanding of identity and access management concepts such as OAuth2/OIDC, JWT and API keys. Experience with Keycloak or a comparable identity provider is an advantage
• Solid grasp of testing practices, version control and CI/CD fundamentals, for example Jenkins or an equivalent pipeline tool
• Familiarity with containerised deployment and infrastructure as code, for example Docker, Kubernetes, Helm or Crossplane, and with API gateways such as Traefik
• Demonstrated ability to solve complex problems on a daily basis
• Ability to thrive in a fast‑paced, agile environment with a sense of urgency and attention to detail
• Ability to collaborate and communicate effectively across multiple teams and multiple time‑zones
• Familiar with current industry trends and understanding of development methodologies and standards
• Interest in AI and agentic capability, for example MCP servers, semantic search, retrieval or document intelligence, is a strong plus
• Willingness to assist in the interview process and to mentor junior team members
