Support Engineer - APAC Risk, Treasury & Post-Trade

WHO WE ARE

Optiver is a global market maker founded in Amsterdam, with offices in London, Chicago, Austin, New York, Sydney, Shanghai, Hong Kong, Singapore, Taipei and Mumbai. Established in 1986, today we are a leading liquidity provider, with close to 2,000 employees in offices around the world, united in our commitment to improve the market through competitive pricing, execution and risk management. By providing liquidity on multiple exchanges across the world in various financial instruments we participate in the safeguarding of healthy and efficient markets. We provide liquidity to financial markets using our own capital, at our own risk, trading a wide range of products: listed derivatives, cash equities, ETFs, bonds and foreign currencies.

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

We are looking for Support Engineers to join our APAC Risk, Treasury, and Post-Trade IT team in Sydney. Our team builds and runs the systems Optiver uses to measure and control its risk exposure, fund its trading, and process its trades after execution. When these systems encounter problems, Optiver's ability to trade safely is affected. Our users are the traders, risk managers and middle-office staff across our APAC offices who depend on these systems every day. Our platforms sit at the end of a chain of internal services, exchanges, brokers and clearers. You'll own their day-to-day operation and the investigation when something looks wrong. The symptom is often a wrong number rather than a stopped process.

Responsibilities:

• Own day-to-day production support for the risk, treasury and post-trade platforms: investigate incidents from the first alert through to root cause, write and ship the straightforward fixes yourself, and escalate to the development team where deeper domain knowledge is needed.

• Work with stakeholders to establish the real impact of an issue and keep them informed while you resolve it.

• Drive problems to resolution even when the cause sits outside the team.

• Reduce the support burden by automating manual workflows, removing recurring failure modes and improving alerting, monitoring and diagnostics.

• Extend our AI-assisted operational tooling for triage, investigation and remediation.

• Manage the technical operation of the production environment: capacity planning, process and host layout, and deployment across more than 1,000 application instances.

 

WHO YOU ARE

• You have 2+ years operating and supporting production software systems, ideally where failure has direct financial or operational consequence.

• You debug systematically, following a problem through logs, data and configuration to its root cause rather than its nearest workaround; you want to fix it in the code, not around it (ours is mostly C++).

• You have strong Linux fundamentals and the confidence to investigate directly on the machine: processes, memory, file systems, networking.

• You are fluent in a scripting language, most usefully Python, with the instinct to automate a task the second time you have to do it.

• You are comfortable with data: competent SQL, and enough numerical curiosity to tell a wrong answer from a right one.

• You are interested in AI and keen to leverage it in your day-to-day work, but you check its work.

• You communicate clearly with non-technical stakeholders under time pressure.

Additional experience we value:

• A solid understanding of the trade lifecycle: clearing, settlement, margin, corporate actions, position and P&L reconciliation.

• Experience with observability tooling, CI/CD pipelines and configuration management across a large estate.

• Experience using LLM or agentic tooling to do operational work.

 

WHAT YOU'LL GET

You’ll join a culture of collaboration and excellence, where you’ll be surrounded by curious thinkers and creative problem solvers. Driven by a passion for continuous improvement, you’ll thrive in a supportive, high-performing environment alongside talented colleagues, working collectively to tackle some of the most complex problems in the financial markets.

In return for your expertise, you will have access to a range of Optiver perks, including:

• The chance to work alongside diverse and intelligent peers in a rewarding environment

• Training, mentorship and personal development opportunities

• Daily breakfast, lunch and an in-house barista

• Gym membership plus weekly in-house chair massages

• Regular social events, including a company trip every two years

• Guided relocation, a competitive relocation package and visa sponsorship where necessary
