Software Engineer jobs at Optiver in Sydney are open now, offering visa sponsorship, a genuine relocation package, and a shot at working on the systems behind one of the world’s biggest trading firms.

About the Role

Optiver is a global market maker that’s been trading since 1986, running out of Amsterdam, London, Chicago, Austin, New York, Sydney, Shanghai, Hong Kong, Singapore, Taipei and Mumbai. Close to 2,000 people work there, and Sydney runs as Optiver’s APAC head office, trading actively across Hong Kong, Korea, Singapore, Taiwan and Japan.

You’d join the Critical Engineering APAC team, the group that builds and runs the systems underneath Optiver’s entire trading stack. That stack processes huge volumes of data, prices thousands of instruments and makes millions of trading decisions a day, all in real time. Your job sits right underneath that, covering real-time risk controls, reference data, trade-lifecycle infrastructure and trading-integrity systems.

This is hands-on C++ work on globally distributed services. You won’t just write code and hand it off, you’ll own slices of the platform end-to-end, from the architecture decisions through to production support. If something breaks or slows down, you’re the one improving it.

Optiver flexes seniority around the quality of your engineering rather than a strict years-on-paper cutoff, so strong problem-solvers with three-plus years of experience genuinely have a shot here.

What You’ll Be Doing

• ✓
  Design, build and operate components of the APAC platform end-to-end
• ✓
  Write production-grade C++ for real-time, low-latency, high-throughput services
• ✓
  Set technical direction and make architecture calls that hold up under load
• ✓
  Translate business problems into pragmatic technical solutions with other teams
• ✓
  Manage deployments carefully and provide production support when needed
• ✓
  Maintain quality through code review, testing and strong observability
• ✓
  Mentor less experienced engineers and raise the team’s engineering bar

What You’ll Need

• ✓
  Strong object-oriented C++ skills, or Java/C# with real motivation to move to C++
• ✓
  Solid computer-science fundamentals: operating systems, data structures, algorithms, networking
• ✓
  Practical Linux/Unix experience and familiarity with a scripting language like Python
• ✓
  Three or more years building and operating production software systems
• ✓
  Experience through a full software lifecycle, from requirements to ongoing operation
• ✓
  A track record of solving hard technical problems and shipping them to real users
