Application Support Engineer – SWIFT & Mainframe, Assistant Vice President

The Mainframe & SWIFT Application Support Specialist is responsible for the end-to-end support, monitoring, and incident management of our Mainframe accounting processes and SWIFT messaging flows. The role ensures operational stability, data accuracy, and timely processing of financial transactions, supporting business-critical fund accounting and custody operations.

Who we are looking for

We are seeking an experienced Application Support Specialist with strong expertise in SWIFT-integrated, fund accounting, custody operations and mainframe ecosystems to support and modernize mission-critical financial applications. The team supports high-volume, highly secure financial systems operating across SWIFT secure zones, cloud-native platforms (AWS/Azure), and legacy mainframe technologies (e.g., IBM Z). These platforms are undergoing transformation to hybrid architectures, combining mainframe stability with cloud scalability and automation. The ideal candidate will play a key role in driving DevSecOps/SRE practices across heterogeneous environments, ensuring secure, resilient, and automated delivery pipelines.

Why this role is important to us

Our technology function, Global Technology Services (GTS), underpins critical financial operations including payments, messaging, and settlement systems integrated with SWIFT networks.

This role is central to:

• Maintaining the security and integrity of SWIFT-connected applications, which operate within tightly controlled secure network zones and access models
• Enabling cloud transformation of legacy mainframe workloads, improving agility, observability, and resilience
• Strengthening compliance with internal controls, external audits, and regulatory requirements tied to financial messaging and data protection

You will contribute to the firm’s broader transformation by bridging traditional mainframe operations with modern cloud-native DevSecOps/SRE practices.
