Business Analyst Payments

Role: Business Analyst (Payments / Fiserv SME)

Location: 100% Remote

Duration : 20 weeks (Start Date : 5/18)

Role Summary
The Business Analyst (Payments / Fiserv SME) is responsible for providing deep subject matter expertise in Fiserv payment processor data, including detailed understanding of Fiserv data fields, coded values, transaction flows, business rules, and mapping logic. This role serves as the primary functional lead for interpreting processor data and translating it into clear business rules, mappings, KPI definitions, and implementation-ready functional specifications.

This individual is expected to play a critical role in bridging the gap between raw Fiserv source data and the target canonical / semantic design, working closely with the Data Architect, Solution Lead, and client stakeholders to ensure that processor-specific logic is accurately understood, documented, and translated for downstream implementation.

Deep hands-on knowledge of Fiserv processor data structures and field-level usage is a core requirement for this role.

Key Responsibilities

• Serve as the primary SME for Fiserv payment processor data, including field-level interpretation and business meaning
  Provide deep expertise in Fiserv data elements, transaction attributes, coded values, status fields, event types, and processor-specific logic
  Analyze and document source-to-business mappings for Fiserv data fields
  Interpret and explain processor-specific transaction lifecycle behavior, including statuses, approvals, declines, reversals, adjustments, settlement-related indicators, and other payment events as applicable
  Lead definition and documentation of business rules, code translations, and field usage guidance
  Partner with the Data Architect to translate detailed Fiserv field logic into canonical structures, semantic models, and implementation-ready mappings
  Support identification and rationalization of overlapping, ambiguous, or inconsistently used Fiserv source fields
  Define and document KPI logic based on Fiserv data, including inclusion/exclusion rules, filters, assumptions, and edge cases
  Facilitate working sessions with business stakeholders and technical teams to clarify field meaning, data usage, and reporting intent
  Support issue triage during design, client implementation, validation, and UAT by clarifying whether issues are related to source interpretation, business logic, or implementation
  Maintain traceability across requirements, Fiserv source fields, mapping rules, transformations, and KPI outputs
  Contribute to documentation, design reviews, knowledge transfer, and implementation guidance for client-led execution

Required Experience

• 5+ years of business analysis or data analysis experience in payments, with direct hands-on experience working with Fiserv processor data
  Deep knowledge of Fiserv payment processor data fields, file structures, coded values, and transaction-level attributes
• Strong understanding of how Fiserv source data is used to support business reporting, operational analysis, KPI definition, and downstream analytics
  Experience documenting field-level mappings, business rules, code translations, and functional logic for payment data environments
  Experience interpreting processor-specific payment events and statuses and translating them into usable business definitions
  Experience working with business stakeholders, architects, and technical teams to resolve ambiguity in source data and reporting logic
  Strong experience with requirements gathering, workshop facilitation, and functional documentation
  Ability to analyze detailed source structures and clearly explain field usage, dependencies, and exceptions

Preferred Experience

• Experience with Fiserv merchant, acquiring, card, settlement, authorization, or transaction reporting data
  Experience supporting source-to-target mapping, decoder-ring initiatives, or semantic-layer/reporting design for payment data
  Familiarity with KPI and metric development in payments environments
  Experience supporting data modernization, Snowflake, or cloud analytics initiatives involving Fiserv data sources
  Knowledge of payment lifecycle concepts such as: authorizations, captures, settlements, reversals, declines, fees, adjustments, disputes/chargebacks
  Experience working in client-facing advisory or implementation support engagements
