Software Engineer – Core Java - High-performance tech meets high-speed trading 🚀

Are you a Java whiz who loves the thrill of solving complex problems and seeing your code make a real-world impact — in milliseconds? My client, a challenger Proprietary Trading firm, is looking for a Software Engineer to join their electronic trading team where technology isn’t just part of the business — it is the business.

In this role, you’ll help power an ultra-efficient global trading platform — the kind that makes lightning-rapid decisions, crunches huge data sets, and thrives in one of the most competitive tech environments around.

What You’ll Be Doing

- Building and refining the core trading systems that keep the platform running at warp speed
- Delivering focused improvements that boost performance, stability, and profitability
- Diving into mission-critical projects across trading, pricing, risk, and analytics
- Working side-by-side with traders to translate ideas into real-time code magic
- Tuning performance to squeeze every last microsecond out of our systems

What You’ll Bring

- Core Java mastery (and bonus points for C++ or C#)
- Scripting chops — ideally in Python




- Previous Experience in high-frequency or low-latency trading environments!
- Confidence working across Windows and Linux
- Solid grasp of network protocols and system architecture
- Clear communicator who thrives in fast-paced, collaborative environments
- A strong academic foundation in Computer Science
- And, of course — a genuine curiosity about financial markets
- Existing visa eligibility to live and work in Australia (essential)

Why You’ll Love It Here - a close-knit team of ambitious engineers, quants, and traders who love to push boundaries, question assumptions, and build things that matter . The environment is open, meritocratic, and refreshingly low on ego.
Expect a culture that rewards creative problem-solving, celebrates curiosity, and encourages you to challenge ideas — even your own.

Collaboration is key, and latency is everything! As such, this role requires mandatory 5 days in the office per week (CBD location)

If you love fast code, smart people, and solving puzzles with real stakes , this is your kind of playground.
