Full Stack Engineer

Full Stack Software Engineer

Melbourne | Full-time | 1-3 Years Experience

About the Opportunity

UCentric is exclusively partnering with a high-growth, Melbourne-based technology venture as they enter a pivotal expansion phase following a successful platform rollout. This organization is at the forefront of Australian-led innovation, now focusing on scaling its engineering capability to support complex product delivery and production readiness.

We are seeking a Full Stack Software Engineer who is eager to contribute to a live, high-performance production environment. This is an ideal role for an engineer with 1-3 years of experience who possesses strong Computer Science foundations and a genuine passion for engineering excellence.

Your Mission

You will build the services that sit between the model and the outside world. This is a role where reliability is a feature. You will design architectures that handle model inference, user requests, and real-time streaming, ensuring the system stays fast and predictable under significant load.

What You’ll Actually Do

• Build and maintain services that handle model inference and user requests.
• Implement critical mechanisms like rate limiting, retries, and graceful failure.
• Design systems that manage complex user sessions and streaming responses.
• Build authentication and access controls for public-scale usage.
• Improve latency, throughput, and the overall reliability of model serving.
• Work with infrastructure and training engineers to integrate new model checkpoints into production.
• Design systems for logging, traces, and evaluation signals to monitor system behavior.

The Kind of Person Who Will Thrive

We are looking for engineers who are:

• Cares about runtime behavior and how large-scale systems behave under real-world constraints.
• Stays calm when production behaves unexpectedly and enjoy debugging real systems.
• Has the rigor to build systems that are hard to break.
• Has a genuine desire to understand how the full AI stack actually works.

Technical Skills & Experience

• Experience: 1-3 years of experience building production software.
• Backend Proficiency: Comfortable building services in modern languages (Python is highly preferred here).
• Systems Design: Experience with APIs, service interfaces, and designing for stability under load.
• Observability: Ability to read logs and metrics to diagnose performance profiles and deployment bottlenecks.

Why Apply? This is a rare opportunity to work at the heart of the full AI stack—from data and training to infrastructure and operations. You will be part of a small, high-impact team that treats product quality and reliability as core components of the intelligence system itself.

How to Apply If you want to build the product surface of a model trained from scratch and ship it to real users, we want to hear from you.
