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
