System Analyst (CBS, Deposits)

We're looking for a System Analyst to join our Core Banking System team and take ownership of our deposit products — checking accounts, savings accounts, and time deposits.

You'll work in a hybrid-delivery setup where part of the build happens in-house with our internal engineering team and part with an external CBS vendor.

That makes you the key link between business stakeholders, our internal engineers, and the vendor — translating needs into clear, actionable specifications for both. If you know deposit mechanics inside out and enjoy turning messy requirements into precise documentation, we'd like to meet!

Key responsibilities

• Analyze business requirements for deposit products (checking, savings, time deposits) and translate them into detailed functional and technical specifications
• Write and maintain requirement documents, user stories, and task descriptions for both the internal development team and the external CBS vendor
• Coordinate with the CBS vendor: define scope, manage change requests, review vendor solutions and assess their impact on existing processes
• Facilitate requirements workshops and grooming sessions with business owners, product managers, and technical stakeholders
• Perform gap analysis of existing CBS functionality against business needs and propose solutions within or around platform constraints
• Participate in system integration design - define data flows and API contracts between the CBS and surrounding systems
• Validate vendor deliverables: review functional designs, participate in UAT, track defect resolution
• Maintain system documentation: functional descriptions, business process flows, data dictionaries, and decision tables
• Support the internal QA team with test scenario preparation and act as an escalation point during testing phases
• Monitor and assess the impact of regulatory changes on deposit product logic, and initiate change requests where necessary

Requirements

• 3+ years as a System or Business Analyst in banking or financial services
• Hands-on experience with core banking systems (any major CBS platform)
• Deep knowledge of deposit product mechanics: checking, savings, term/time deposits
• Proven experience writing requirements for external vendors and controlling delivery
• Strong documentation skills: use cases, BRD/FSD, BPMN, data flow diagrams
• Experience with REST API analysis and integration design
• English B2+ — daily use with the vendor and international teams

Nice to have

• Experience with specific CBS platforms
• Familiarity with regulatory requirements for deposits
• SQL proficiency for data validation and analysis
• CBAP, CCBA, or equivalent certification
• Experience in Agile / SAFe delivery environments
