About the role

We're seeking a Backend Python Engineer to design and build the core systems behind an AI-enhanced document and development tool used across enterprise by both technical and non-technical users alike.

This is a greenfield project, giving you the opportunity to make influential decisions including the choice of frameworks and establish a robust backend foundation for years to come.

This role suits someone who thrives in a collaborative environment and takes pride in building reliable, scalable, and secure backend systems. You value clean code, test-driven development, and engineering best practices, and you understand how thoughtful design supports long-term maintainability.

What you will do

• Collaborate with the team to implement a backend that supports the application's core AI-assisted features.
• Build reliable, scalable and extensible backend services to support product growth both as individually deployed on-premise runtimes and cloud managed services as the product grows and user needs evolve.
• Develop and integrate a Role-Based Access Control (RBAC) framework for the application, working with customer authentication and authorisation systems.
• Implement and integrate with services powering embeddings, Graph Retrieval-Augmented Generation, and AI driven capabilities.
• Validate your work through unit, integration, and system tests, iterating based on feedback.

Experience and qualificationsRequired:

• Full working rights in Australia.
• Tertiary qualifications in Software Engineering or equivalent experience.
• Strong engineering fundamentals with a deep understanding of software design principles (Clean Code, SOLID, TDD).
• Strong proficiency in Python and familiarity with its standard libraries.

Preferred:

• Familiarity with developer tooling (Git, JIRA, Confluence, Docker, Github Actions).
• Experience working on greenfield projects emphasising maintainability, testability, and extensibility.
• Familiarity with asynchronous frameworks such as FastAPI or asyncio and scalable backend service design.
• Experience integrating with authentication and authorisation frameworks (LDAP, OIDC, SAML) and implementing RBAC models.
• Experience building data platforms supporting AI/ML pipelines, embeddings databases (e.g. Chroma, Pinecone, Weaviate, Milvus), and vector search systems.
• Familiarity with RAG architectures, including document preprocessing, chunking, and hybrid retrieval strategies.
• Experience integrating with LLM APIs (OpenAI, Anthropic, etc.) and prompt orchestration frameworks.
• Knowledge of control infrastructure and internal services (e.g., MCP servers) for data management or orchestration.

We understand applicants' work and life experience comes in many ways, shapes and forms. If your experience is close, but not a perfect match, and you believe you could be successful in this role, we're happy for you to apply.
