System Reliability Engineer – Sydney CBD - Optiver

Who we are

Optiver is a Premier Global Trading firm focused on market-making, who take pride in our people and our technology. From our Sydney office, we trade across the APAC region and due to continued growth we are constantly on the lookout for talented and passionate people. Although trading is our game, our technology helps us to achieve our goals. Our IT team works closely with trading to help guide and drive our business and therefore is an integral contributor to our success.

What you’ll do

In an environment where microseconds matter, our systems need to perform at their peak, all day, every day. As a Trading Systems Engineer, you work in the production environment where you are a custodian of the systems that drive Optiver’s core business.

You’ll be responsible for the entire trading system, from end-to-end (servers, networks, software deployments etc). You'll be entrusted with the delivery of game-changing ideas, performance improvements and coordinating incident responses. Your goal is flawless execution at every stage.

Whilst this is not a development or systems admin role, it incorporates elements of both. You’ll often find yourself on the trading floor as a trusted advisor to our traders on operational decisions. You excel in taking real business problems and solving them with cutting edge technology.

Who you are

You're a solution-oriented engineer who wants to have a direct impact on the business. You want to work with systems end-to-end and you don’t shy away from intricate low level details. You love to problem solve, troubleshoot and get your hands dirty with technology. You’re customer-focused, communicate strongly and enjoy engaging others face-to-face. A critical thinker when it comes to troubleshooting and analysis, you recognise the smallest of details and patterns, leave no stone unturned, ask all the right questions and are always looking to improve how things work.

Skills and experience
• Min 3 years’ experience working in System Administration, IT Operations / DevOps / Release management or any technical role that requires complex troubleshooting, incident management and production support
• A solid understanding of Linux is required
• Experience with Python scripting, networking and/or software development is highly desirable
• Excellent verbal, written and face-to-face communication skills with the ability to liaise with both technical and non-technical stakeholders alike
• Demonstrated ability to keep a ‘cool head’ when under pressure

In-house trading training is provided so you’ll be well equipped to liaise with traders. You’ll learn about market operations, trading concepts and strategies and how that translates to the technology that makes Optiver as a business tick.
