Senior Rust Engineer

About the Role

An exciting opportunity has arisen for a Senior Rust Engineer to join a growing technology organisation building next-generation data infrastructure platforms. This role will focus on designing, developing and optimising high-performance backend systems that can process large-scale datasets with speed, reliability and scalability.

Working within a highly skilled engineering team, you'll leverage your expertise in Rust, asynchronous programming and distributed systems to solve complex technical challenges, influence architectural decisions and contribute to the ongoing evolution of a mission-critical platform.

Key Responsibilities

Systems & Software Engineering

• Design, develop and maintain high-performance backend systems using Rust and Java.
• Build scalable, reliable asynchronous services using modern concurrency patterns.
• Develop APIs, internal tooling, reusable libraries and engineering frameworks.
• Contribute to system architecture and technical decision-making.
• Deliver solutions for large-scale data processing workloads.

Performance & Reliability

• Optimise throughput, latency, memory utilisation and I/O performance.
• Analyse and improve memory ownership, buffer management and serialization efficiency.
• Identify and resolve performance bottlenecks across distributed systems.
• Ensure production readiness through testing, debugging, monitoring and code reviews.
• Drive improvements in scalability, reliability and maintainability.

Collaboration & Delivery

• Partner with engineering, product and platform teams to deliver business outcomes.
• Take ownership of technically complex and ambiguous challenges.
• Contribute to engineering best practices, technical documentation and knowledge sharing.
• Work effectively with globally distributed teams and stakeholders.

Essential Requirements

• 5+ years of software engineering experience, including strong Java development expertise.
• 2+ years of hands-on commercial Rust development experience within production environments.
• Strong experience with asynchronous Rust programming, ideally using Tokio.
• Deep understanding of Rust memory ownership, borrowing, lifetimes, allocations and buffer management.
• Proven experience building and delivering distributed systems or high-performance backend applications.
• Strong knowledge of concurrency, backpressure handling, cancellation, streams and async execution models.
• Experience designing APIs, internal libraries or reusable engineering frameworks.
• Excellent debugging, troubleshooting and performance optimisation skills.
• Ability to independently solve complex technical problems and drive solutions through to delivery.
• Strong communication and stakeholder engagement skills.

What's on Offer?

• Permanent opportunity with a growing technology business.
• Work on challenging, large-scale engineering problems using Rust.
• Influence architecture and technical direction.
• Collaborative, engineering-led environment.
• Chatswood location with flexible working arrangements.
