Senior Software Engineer

WHO WE ARE

Optiver is a tech-driven trading firm and leading global market maker. For over 35 years, Optiver has been improving financial markets around the world, making them more transparent and efficient for all participants. With more than 1,700 employees in offices around the world, we’re united in our commitment to improve the market through competitive pricing, execution, and thorough risk management. By providing liquidity on multiple exchanges across the world, we actively trade on 70+ exchanges, where we’re trusted to always provide accurate buy and sell pricing – no matter the market conditions.

Optiver’s Sydney office is one of the primary players within Asian markets, trading a range of products. Established in 1996, we're an active participant on the Hong Kong, Korea, Singapore, Taiwan and Japan exchanges, and act as Optiver’s APAC head office.

WHAT YOU’LL DO

Optiver leverages technology to solve a variety of complex problems: optimising for scarce bandwidth, responding to market events with nanosecond speed, automatically pricing complex sets of financial instruments with extremely low error tolerance, and analysing huge volumes of data. Our systems are built to add to the stability of the market, not detract from it; therefore, they must operate at peak efficiency in the most extreme market conditions.

Our Senior Software Engineers not only lead technical projects, but also help set the direction for our trading infrastructure and serve as role models within the organisation. As part of the team, you will collaborate with fellow Engineers, Traders, and Researchers to develop a deep understanding of trading, exchanges and what the 'machine' is doing. Your challenge is to further innovate and maintain the foundation underlying our wider infrastructure.

Your other responsibilities will depend on what team you go into, but we expect our Senior Engineers to also be involved with:

• The design, development and deployment of services that comprise our globally distributed trading platform.
• Delivering large bodies of well-engineered code.
• Building partnerships across the business to ensure we're feeding the best ideas into our solutions.
• Managing deployments to reduce risk and provide production support where required.
• Finding the simplest, cleanest solutions and continually optimise them.
• Building software that balances complex system performance in a reliable trading environment.
• Mentoring junior engineers.

WHO YOU ARE

Optiver needs our next Senior Software Engineer to be someone with:

• A solid grasp of Computer Science fundamentals like operating systems, data structures and algorithms.
• As our main body of software is written in C++ and runs on Linux, you will either need to have extensive experience in this language and platform or be more than willing to learn on the job. Next to C++, we also extensively use Python, C# and other languages in Optiver, and you are therefore expected to be willing and able to learn new languages quickly.
• Proven ability to work through the full software development lifecycle, from gathering requirements, to testing and deployment.
• Experience making architectural recommendations on IT solutions, design & approach.
• A passion for solving complex problems with well-engineered, fit for purpose, code.

WHAT YOU'LL GET

• The chance to work alongside diverse, intelligent, and driven peers in a rewarding environment
• Competitive remuneration, including an attractive bonus structure and additional leave entitlements
• Training, mentorship, and personal development opportunities
• Gym membership plus weekly in-house chair massages
• Daily breakfast and lunch facilities
• Regular social events including an annual company trip
• A work-from-home allowance and support
• Guided relocation, a competitive relocation package and visa sponsorship where necessary

As an intentionally flat organisation, we believe that great ideas and impact can come from everyone. We are passionate about empowering individuals and creating diverse teams that thrive. Every person at Optiver should feel included, valued, and respected, because we believe our best work is done together.

Our commitment to diversity and inclusion is hardwired through every stage of our hiring process. We encourage applications from candidates from all backgrounds, and we welcome requests for reasonable adjustments during the process to ensure that you can best demonstrate your abilities.
