Sydney, New South Wales, Australia AIR Trading Full time $120,000 - $180,000 per year

We're looking for an
Infrastructure & Systems Engineer
to help design, build, and optimise the systems that power our trading and research operations.

You'll take ownership of infrastructure choices — from evaluating hardware and networking options to monitoring and optimising production environments — ensuring that every layer of the system is robust, scalable, and fast.

What You'll Do

  • Design and deploy new infrastructure for trading, research, and data systems.
  • Evaluate and recommend optimal hardware, networking, and co-location setups.
  • Optimise system performance, latency, and reliability across environments.
  • Work closely with trading, quant, and software teams to align infrastructure with strategy.
  • Own lifecycle management — from initial deployment to refresh and scaling.

What You Bring

  • Strong background in systems or infrastructure engineering (Linux, networking, hardware).
  • Experience building or supporting high-performance, low-latency systems.
  • Deep understanding of servers and network hardware; able to evaluate trade-offs in cost, speed, and stability.
  • A builder's mindset — curious, pragmatic, and decisive.
  • Experience in trading, or latency-sensitive environments.

About AIR

  • AIR is a technology-driven proprietary trading firm building advanced infrastructure and systems to power our AI quantitative trading strategies across global markets. We're a small, high-performance team focused on innovation, precision, and speed — and we're now expanding our infrastructure capabilities in Sydney.
