Working primarily in Linux/Unix environments, you’ll monitor production systems, investigate alerts and processing issues, manage operational work queues, respond to incidents, and help ensure services meet strict availability and processing SLAs.\nThis is a production-focused application support role rather than an infrastructure or service-desk position. You’ll work as part of a globally distributed operations team and collaborate with Development, Infrastructure, Client Services, exchanges, data vendors, network providers, and other technical teams.\nYou’ll fit right in if you’re collaborative, methodical, comfortable working under pressure, and able to analyse information from multiple sources to identify what has failed, assess its impact, and determine the appropriate recovery or escalation path.\nWhat You’ll Do\nOperate and support critical production applications and data-processing services in Linux/Unix environments.\nPerform real-time monitoring of application health, data flows, batch processing, alert generation, capacity, and service availability.\nInvestigate monitoring alerts and production issues, restoring service where possible and escalating to the appropriate technical teams when required.\nOwn and progress operational tickets through investigation, resolution, escalation, documentation, and closure, ensuring that priorities and status updates remain accurate.\nMonitor and troubleshoot end-to-end data-processing workflows, including client uploads, market and reference data feeds, file transfers, data transformation, alert generation, and downstream availability.\nExecute documented startup, shutdown, recovery, scheduling, backup, restoration, and reprocessing procedures.\nPerform approved production deployments and configuration changes using established change-management processes.\nComplete post-deployment verification to confirm that changes have produced the expected result and have not adversely affected production services.\nRespond to production incidents, contributing to service restoration, technical investigation, escalation, event timelines, root-cause analysis, and remediation activities.\nTroubleshoot application performance and connectivity issues across the application, operating system, storage, device, and network layers.\nWork with Development, Infrastructure, Client Services, exchanges, data vendors, and network providers to investigate and resolve operational issues.\nPerform data or alert reprocessing when required, including validating inputs, protecting existing production data, monitoring processing, and verifying the resulting output.\nProvide clear shift handovers to regional teams, ensuring continuity of outstanding alerts, incidents, tickets, deployments, and other operational work.\nCreate and maintain runbooks, troubleshooting procedures, deployment instructions, and knowledge-base documentation.\nIdentify opportunities to automate repetitive tasks, reduce false alarms, improve monitoring coverage, and increase the reliability and supportability of production services.\nFollow incident, change, access-control, security, and operational-risk procedures when working on production systems.\nParticipate in a rostered weekend on-call rotation and occasional out-of-hours production work.\nWhat You’ll Bring\nA degree or diploma in Computer Science, Information Systems, or a related discipline, or equivalent practical experience.\nThree or more years of experience in application support, technical operations, production support, trading technology, data-processing, network operations, or a related environment.\nA solid understanding of Linux/Unix environments, including common command-line tools, filesystem and process management, log analysis, and basic Bash or shell scripting.\nThe ability to troubleshoot application behaviour across operating system, process, storage, device, and network layers.\nStrong analytical and problem-solving skills, with the ability to combine information from monitoring alerts, logs, tickets, system behaviour, and stakeholder reports.\nThe ability to identify correlations between discrete events, assess business and service impact, and contribute effectively to root-cause investigations.\nExperience working with monitoring, ticketing, incident-management, and change-management tools and processes.\nStrong written and verbal communication skills, with the ability to communicate technical information clearly and accurately to technical teams, business groups, clients, and client representatives.\nStrong organisational skills, with the ability to prioritize competing demands while maintaining accurate records and following controlled operational procedures.\nThe ability to work calmly and methodically during production incidents and periods of increased operational pressure.\nA collaborative approach and willingness to develop knowledge across a complex application and data-processing environment.\nAvailability to participate in rostered weekend on-call support and occasional planned out-of-hours work.\nNice to Have\nExperience supporting applications used in financial markets, trade surveillance, market data, or other regulated production environments.\nExperience with Git or Bitbucket-based deployment and configuration workflows.\nKnowledge of monitoring and observability tools such as Zabbix, Datadog, or Splunk.\nExperience with Jira or a comparable operational ticket-management platform.\nExperience with Python, Perl, or more advanced Bash/shell scripting.\nFamiliarity with AWS-hosted applications, containers, or hybrid cloud and on-premises environments.\nExperience supporting file-based or batch-oriented data-processing pipelines.\nUnderstanding of ITIL-aligned incident, problem, and change-management practices.\nRelevant certifications in ITIL, Linux, AWS, networking, or a related technical discipline.\nThis position is based in Sydney and offers a hybrid working arrangement with at least two days per week in the office, subject to change.\nThe role supports globally delivered production services and works closely with operations and technical teams across multiple regions. It includes participation in a rostered weekend on-call rotation and occasional planned work outside normal business hours.\nBenefits & Rewards\nWe offer a competitive, well-rounded rewards package designed to support the financial, physical, and emotional well-being of our employees and their families (where applicable).\nFor more information, visit Nasdaq Benefits & Rewards Career Page.\nCome as You Are\nNasdaq is an equal opportunity employer.
