Backend Software Engineer

Software Engineer (Backend)

Melbourne | Full-time | 1–5 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 an early-career Software Engineer (Backend) who is eager to contribute to a live, high-performance production environment. This is an ideal role for an engineer with 1–5 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

In line with our UCentric values of being authoritative yet approachable, 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: 1–5 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.
