Senior Backend Engineer - High-Performance Systems

Melbourne / Hybrid

Permanent

They are a high-performing Australian technology company operating at significant scale, delivering seamless real-time digital experiences to millions of users. Engineering excellence sits at the core of what they do - from clean architecture and resilient microservices to high-throughput, low-latency systems where performance truly matters.

Their backend ecosystem is complex and event-driven, and reliability is non-negotiable. As a Senior Engineer, you’ll play a key role in designing, building, and optimising APIs and distributed services that directly impact customer experience at scale.

What You’ll Do:
  • Design, develop, and maintain highly performant backend systems and APIs
  • Build and optimize microservices architecture for scalability and resilience
  • Write clean, testable code with unit and integration tests
  • Own the full development lifecycle, from design to post-go-live support
  • Mentor and support junior engineers, fostering a culture of learning and collaboration
We're looking for a mix of the following:
  • Strong experience in .NET and C#
  • Expertise in event-driven architecture and messaging platforms (Kafka, RabbitMQ, AWS EventBridge)
  • Solid understanding of multi-threading and low-latency programming techniques
  • Hands-on experience with distributed caching (Redis, Memcached)
  • CI/CD experience (GitHub Actions, Octopus, Jenkins)
  • Cloud-native mindset with experience building scalable, self-healing infrastructure
  • A passion for producing high-quality code and leveraging best practices like TDD/BDD
  
What's on offer?
  • We have up to $175k package
  • Flexible hybrid working
  • Strong benefits - one of the strongest on offer in Aus
  • Bonus scheme
  • Genuine scope to climb the ladder
