Support Engineer - APAC Risk, Treasury & Post-Trade

OptiverSydneyRemoteFull-time11 Sept 2026

Optiver is seeking Support Engineers to join its APAC Risk, Treasury & Post-Trade IT team in Sydney. The role involves owning day-to-day production support for risk, treasury and post-trade platforms, investigating incidents, automating workflows and managing a large production environment. Requires 2+ years supporting production software systems, strong Linux fundamentals, Python scripting and SQL.

What you'll do

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.
