Senior Python engineer building and operating production-grade backend services and enterprise AI workflows (agents, RAG, MCP, LLM evaluation) for a large enterprise, hybrid with 3 office days per week in Sydney. Core stack: Python, LLM agent frameworks (LangGraph/LangChain/Google ADK), cloud (GCP/AWS/Azure), CI/CD and containers.
We’re looking for multiple Senior Python Developers to join a high-performing engineering team building production-grade AI capabilities across a large enterprise environment.
This is a software engineering role first, with Python at the centre. You’ll design, build and operate backend services and AI-enabled workflows used across customer-facing and internal platforms, with a strong focus on production quality, reliability and scalability.
What you’ll be working on
You’ll build and support:
You’ll ideally have:
We’re particularly interested in engineers who have moved beyond prototypes and have built real production AI systems.
Relevant experience could include:
This is a chance to work on enterprise-scale AI engineering in an environment where Python, software engineering and production AI are all central to the role.
You’ll remain hands-on while contributing to architecture, engineering standards and the evolution of AI-enabled systems across the organisation.
We are looking for both mid-level and senior developers. Salaries range between $160,000 - $240,000 plus bonus.
3 days in the office per week.
