Experienced QuantDev/Engineer (C#)

About the Role

We're looking for an experienced Software Engineer with 5+ years of professional development experience to join our technology team. This is an excellent opportunity for an experienced developer looking for genuine autonomy and ownership from day one—and, as you settle in, the opportunity to mentor others joining the team.

You'll work alongside experienced software engineers, quantitative developers, and Unix engineers on systems designed for rigor, transparency, and automation. Every model is understood and owned by the team that builds it. You'll have the opportunity to work across a range of projects, take ownership of complex systems from the outset, and help shape how new technologies and approaches are adopted.

• Develop and maintain full-stack applications using C# / .NET, working with technologies including SQL, NoSQL, AWS, Grafana, Python, and MATLAB.
• Design and build high-throughput, real-time trading systems.
• Solve complex engineering challenges, including synchronizing data feeds from disparate locations around the world.
• Work closely with quantitative researchers and Unix engineers to understand requirements and develop effective solutions.
• Lead code reviews, testing, and the continuous improvement of our systems.
• Own the full software development lifecycle for the systems you build, from design through to deployment and production support.
• Contribute to the reliability and robustness of our trading platform, including participation in a collaborative on-call rotation.
• Have the opportunity to broaden your skillset into quantitative development, particularly if you have a strong mathematical aptitude and an interest in financial markets.

Requirements

We're open to two types of candidates:

• Experienced software engineers who haven't worked in finance but are looking for a technically challenging new environment; or
• Quantitative developers with experience building front-office trading systems.

You'll have:

• 5+ years of professional development experience, with C# / .NET preferred. Candidates with strong commercial experience in Java, C++, or another object-oriented language will also be considered.
• A good understanding of fundamental software engineering concepts.
• Experience working with databases and writing SQL.
• A methodical approach to solving technical problems.
• The ability to learn new technologies and concepts quickly.
• Strong attention to detail and a commitment to writing reliable, maintainable code.
• Good communication skills and the ability to work effectively as part of a small team.
• Curiosity and an interest in understanding how things work, rather than simply getting things to work.

Nice to have:

• Experience with Unix/Linux, Python, AWS, networking, distributed systems, or financial markets—we're more interested in your engineering ability and potential than a checklist of technologies.

Full working rights in Australia required. Sponsorship is not available. A bachelor's degree in Computer Science, Engineering, Mathematics, Physics, or a related STEM field is required.

Benefits

• A competitive salary, together with an uncapped performance-based bonus.

Technology genuinely matters to the business here. You'll have genuine autonomy from day one—full ownership of the systems you build, without layers of bureaucracy—and, as our team grows, the opportunity to mentor engineers earlier in their career.
