Senior Java Engineer - Low Latency

Salary: Up to $300,000-$400,000 per annum, incl. super

Want to build with the best?

Join a cutting edge Financial Technology firm backed by a leading global capital markets institution. In this newly created role you will lead a critical project to decouple their flagship digital client portal from their internal trading core. You will report directly to the CTO and work alongside the local development lead to drive major performance and scalability gains.

They value highly collaborative, low-ego developers who enjoy building as a team. Our engineering pod actively uses modern AI development accelerators to eliminate boilerplate drag and ship high quality code faster.

If you enjoy solving complex concurrency, JVM tuning, and high-performance socket challenges, this is your next desk.

What you’ll be doing:

• Taking ownership of splitting shared execution resources to completely isolate client-facing market making engines from internal trading cores.
• Designing and optimizing highly concurrent TCP/IP sockets, custom serialization protocols, and multi-threaded JVM processing pipelines to eliminate performance drag.
• Building automated, systematic "on-behalf-of" (OBO) trade booking workflows and FIX-compatible gateways to transition legacy voice booking channels.
• Integrating generative AI development tools directly into your day-to-day environment to streamline unit testing, profiling, and feature execution.

What you'll bring to the team:

• Proven engineering mastery in Core Java.
• Strong technical exposure to institutional electronic trading architectures (e.g OMS/EMS, execution gateways, or real-time pricing feeds) specifically for linear and cash products.
• A low-ego, team-first attitude with a genuine ease using modern AI-assisted engineering tools to accelerate development cycles.

What else is offered:

• A highly competitive package of $300,000 – $400,000 AUD per annum, inclusive of super.
• 100% remote flexibility to work from any location in Australia - rare occasion to get together in Sydney
• High profile, institutional-scale infrastructure scope offering a clear, proven local path for long term contract extension / permanent role.
• A progressive, tech first culture that values software output, engineering execution, and developer well-being over corporate overhead.
