Summary
✨ AI‑Generated
A fully remote contract opportunity for a backend developer to design, build, and optimize APIs, data pipelines, microservices, and scalable server-side systems supporting AI workloads. The role emphasizes clean, testable code and high-performance infrastructure for training and inference, with flexible weekly commitment.
Highlights
Fully remote and flexible contract work with 10–40 hours per week, focused on scalable backend systems, APIs, data pipelines, and infrastructure supporting AI training and inference.
Description
About The Role
What if the code you write could directly power the AI systems shaping how millions of people interact with technology? We're looking for Back End Developers in Sydney to design, build, and optimize the server-side systems and APIs that drive cutting-edge AI products — from data pipelines and model-serving infrastructure to scalable microservices that handle real-world traffic at scale.
This is a fully remote, flexible contract role.
Whether you're a seasoned engineer looking for meaningful project work or a strong developer ready to apply your skills to AI-adjacent infrastructure, this is your chance to build things that matter.
