Sr Domain Sales Engineer; Banking Core Platforms

The Senior Domain Sales Engineer – Banking Core Platforms is a hybrid domain expert, technologist, and pre-sales solution professional who works directly with clients to shape, design, and validate solutions before they are sold and delivered.

Domain Expertise

The ideal candidate is a technologist in cloud, data, API, and AI/ML, with deep expertise in the telecommunications industry, bringing both technology architecture knowledge and hands-on industry process experience across:

• Core Banking Platforms & Process Knowledge — Working understanding of how core banking systems operate end-to-end: account origination, general ledger, transaction processing, and reconciliation — not necessarily as a core banking developer, but as someone who has architected, implemented, or managed the systems and integrations that sit on top of or connect to platforms such as Temenos, Finacle, FIS, Fiserv, or Jack Henry.
• Deposits & Loans — Experience with systems supporting retail and commercial deposit account lifecycle (account opening, maintenance, interest calculation, statements) and lending platforms covering origination, underwriting, servicing, and collections — including how these processes are enabled and modernized through cloud-native architectures and API-led connectivity.
• Payments & Cards — Hands-on familiarity with payment rails (ACH, wire, RTP, SWIFT), card issuing and acquiring platforms, dispute management, and the end-to-end transaction lifecycle from authorization through settlement and reconciliation — including experience with platforms such as Mastercard, Visa, FIS World Pay, or ACI.
• Retail Banking Systems — Understanding of the systems and digital channels that underpin retail banking: mobile and online banking platforms, branch systems, CRM, and omnichannel customer engagement — and how these integrate with core platforms and data layers to deliver a unified customer experience.
• Capital Markets — Familiarity with front-to-back capital markets workflows: trade capture, order management, position keeping, trade confirmation, settlement, and regulatory reporting — and the systems that support them (e.g., Murex, Calypso, Bloomberg, or Broadridge), with an understanding of how cloud and data platforms are modernizing this landscape.
