Python Software Engineer | Sydney, Hybrid | Python, FastAPI, Computer Science, AI/LLMs, C++/Golang | Baseline Clearance

I'm working with an awesome international company who are looking for an experienced Python Software Engineer, relatively early on into their career to join a growing product engineering team. Here, you’ll work closely with R&D, robotics specialists, and multi-agent AI teams, turning prototype algorithms and systems code into production-grade, maintainable software.

You’ll own core backend and systems engineering capability, guide delivery quality, and work with outsourced or offshore contributors as the senior within your domain. This is a product-focused role, suited to engineers who have worked in high-reliability or regulated environments, robotics, simulation, or complex engineered systems.

Python Software Engineer Responsibilities

• Implement and maintain backend components and APIs using Python, ensuring scalability, testability, and good engineering practice
• Work with R&D teams to convert prototype code (algorithms, modelling, autonomy behaviours) into stable, maintainable production software
• Provide technical oversight to offshore teams or contractors delivering backend or systems components
• Participate in architecture discussions, code reviews, and engineering quality improvements
• Help shape long-term backend and systems architecture and products, including driving innovation with AI & LLM systems.

Python Software Engineer Requirements

• Professional experience with Python in a commercial or highly engineered environment
• Ideally some commercial experience working on NLP, LLMs, or intelligent AI/ Agentic AI workflow automation
• Background in product engineering, ideally within regulated, safety-critical, or complex engineering industries (defence, robotics, medical, industrial systems, etc.)
• Strong grounding in software engineering principles (design, testing, maintainability, structured development practices)
• Ability to interpret prototype or research-grade code and convert it into scalable, production-ready systems
• Excellent communication skills; comfortable providing technical leadership or guidance to external contributors
• Baseline clearance or ability to obtain one
• Willingness to learn/use other programming languages such as C++/Golang as the team & products evolve over time.

If interested, please apply with your most up-to-date resume & I'll be in touch.
