Responsibilities

• System & Integration Analysis: Elicit, define, and document technical requirements for distributed systems, including REST APIs, API contracts, request/response models, error handling, and service dependencies.
• Data Modeling & Schemas: Analyze and document data modeling requirements, data schemas, field-level specs (data types, constraints, required/optional fields), and ensure versioning and backwards compatibility across integrations.
• Technical Flow Design: Document both synchronous (request/response) and asynchronous (messaging/event-driven) processing flows.
• Architecture & Scope Governance: Analyze capability gaps within the Customer’s organization and propose strategic, scalable solution options considering relational and NoSQL storage technologies.
• Stakeholder & Engineering Collaboration: Bridge the gap between non-technical business stakeholders and engineering teams by translating business needs into detailed technical user stories with edge cases and acceptance criteria.
• Requirements Lifecycle Management: Establish and maintain robust requirements lifecycle processes from inception to delivery, including non-functional requirements (NFRs), external interfaces, and technical constraints.
• Meeting & Workshop Facilitation: Facilitate high-stakes technical refinement sessions, workshops, and consensus-building meetings across engineering and business units.
• Mentorship & Best Practices: Mentor other analysts, establish standard technical BA practices across streams, and contribute to the corporate knowledge base.
• Acceptance & Validation: Oversee technical implementation, validate API/system behavior, and lead internal and external user acceptance testing (UAT).

Requirements

• APIs & Distributed Systems: Strong technical understanding of APIs and distributed architecture, with hands-on experience defining REST APIs, API contracts, request/response payloads, HTTP status code error handling, and service dependencies.
• Data Modeling & Schemas: Good understanding of data modeling concepts and data schemas, including defining data types, validation rules, required vs. optional fields, system constraints, as well as API/schema versioning and backwards compatibility.
• Databases & Storage: Working knowledge of database architectures and storage technologies, including hands-on familiarity with relational (SQL) and NoSQL databases.
• Processing Models: Clear understanding of synchronous vs. asynchronous processing patterns (e.g., standard request/response vs. messaging/event-driven flows like Kafka/RabbitMQ).
• Technical Modeling: Solid experience in UML (Sequence Diagrams, System Context Diagrams) and BPMN process modeling.
• Domain & Experience: 3+ years of IT industry experience as a Business Analyst, including extensive collaboration with international clients and software architecture teams from Discovery through Production.
• Agile & Lifecycle Management: Deep understanding of the SDLC and proven experience as an Agile practitioner managing backlog refinement, traceability, and change control.
• Communication Excellence: Advanced English verbal and written communication skills, with a proven ability to translate complex technical architectures into simple terms for stakeholders and executive management.
• Tool Proficiency: Mastery of Jira and Confluence for writing technical user stories, alongside API/data tools (e.g., Postman, Swagger/OpenAPI, or database clients).
• Proactive Problem Solving: Eager to suggest technical alternatives, evaluate system trade-offs, and take complete ownership of the technical BA scope during Discovery or Pre-sales phases.
• Mentorship & Accountability: Capable of assessing deliverables from junior colleagues, fostering growth, and operating with a high degree of personal accountability.
