• Collaborate closely with development teams to escalate bugs, manage software releases, and contribute to the continuous improvement of the platform.
• Communicate system status, issue updates, and resolution summaries clearly and concisely to business and technology stakeholders.
• Adhere strictly to ITIL best practices for Incident Management, Problem Management, and Change Management.
• Participate in weekend support rotas, application deployments, and disaster recovery tests as required.

• Strong proficiency in SQL, with significant hands-on experience with Sybase, KDB, Oracle or a similar enterprise-level database.
• Proven troubleshooting skills in a distributed systems environment, including Unix/Linux, Windows, and various middleware technologies (e.g., Tibco, Solace, Kafka).

• Demonstrable experience in a front-office application support or production services role within a financial institution.
• In-depth knowledge and practical application of ITIL concepts are mandatory.

• Ability to perform effectively under pressure and prioritise tasks in a fast-paced trading environment.
• A proactive and analytical approach to problem-solving.

• A strong understanding of Equities Derivatives products (e.g., Options, Swaps, Futures, Warrants).
• Familiarity with derivatives pricing concepts, PnL attribution, and the "Greeks" (Delta, Gamma, Vega, Theta).

• Experience with scripting languages such as Shell, Python, or Perl for automation and reporting.
• Knowledge of job scheduling tools like Autosys.
