My client, a tier-1 buyside firm, is hiring multiple C# Software Engineers across all seniority levels for its Sydney team. Engineers from tech firms are welcome—no previous finance or trading experience is required. You’ll work alongside traders, researchers and engineers to develop the services, real-time systems and applications supporting the firm’s trading business.

- Own features throughout the delivery lifecycle, from understanding requirements to testing and production deployment.
- Improve system performance, reliability and scalability.




- Investigate technical issues and implement sustainable solutions.
- Collaborate directly with trading, research and engineering teams.
- Strengthen development practices through automation, testing and tooling improvements.

What we’re looking for

- 5+ years of C# development experience with sound programming fundamentals.
- An understanding of object-oriented design, debugging and maintainable software.
- Familiarity with backend systems; exposure to multithreading or performance optimisation is advantageous.
- Strong problem-solving and communication skills.
- A degree in computer science, engineering or a related technical field.
- An interest in learning about trading technology—not prior financial industry experience.
