Sydney, New South Wales, Australia The Argyle Network Full time $120,000 - $180,000 per year

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-fast 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.
