Descrizione del lavoro

About Us: Banank – a fresh chapter in banking technology!

We combine generational wisdom with cutting-edge tech to create a top-notch banking experience for digital natives.

Role Overview

Banank is seeking a highly experienced Principal Systems Analyst to drive the analysis, design, and evolution of complex technology solutions powering our digital banking platform.

This is a senior hands-on technical role that combines deep systems analysis, solution design, financial domain expertise, and cross-team technical leadership. You will translate complex business requirements into clear, actionable functional and technical specifications, ensuring that solutions are scalable, secure, reliable, maintainable, and aligned with Banank's overall technology architecture.

You will work closely with Product Owners, Business Stakeholders, Architects, Backend Engineers, Data Engineers, QA, Security, and Platform teams throughout the entire software development lifecycle, from requirements discovery and solution design to implementation, testing, and production delivery.

We are looking for someone who thinks like an engineer, understands business like an analyst, and approaches problems with the architectural perspective of a technical leader.

You should be comfortable working directly with backend technologies, understanding source code, investigating system behaviour, and participating in technical design decisions.

We value pragmatic engineering and the principle that solutions should be as simple as possible while meeting business, security, scalability, and regulatory requirements.

The ideal candidate is proactive, independent, technically curious, and confident enough to challenge requirements and architectural decisions constructively, always seeking the most effective solution rather than simply documenting what has been requested.

Key Responsibilities

Business & Systems Analysis

• Lead the analysis of complex business requirements and translate them into comprehensive functional and technical specifications.
• Work closely with business stakeholders, Product Owners, and engineering teams to understand business objectives, operational workflows, and system requirements.
• Analyse existing business processes, identify inefficiencies, and propose improvements.
• Define functional requirements, use cases, user stories, acceptance criteria, business rules, and exception handling scenarios.
• Ensure requirements are complete, consistent, testable, traceable, and aligned with business objectives.
• Proactively identify gaps, ambiguities, dependencies, and potential conflicts in requirements before implementation.
• Lead hands-on system analysis and contribute to the architecture and design of complex backend solution.
• Translate business requirements into scalable, secure, reliable, and maintainable technical designs.
• Define system interactions, component responsibilities, integration patterns, data flows, and service boundaries.
• Design our banking platform solution using modern microservices, event-driven architectures, and distributed systems principles.
• Apply pragmatic engineering principles, keeping solutions simple, practical, and easy to understand and maintain, avoiding unnecessary complexity and overengineering.
• Evaluate architectural alternatives, identify technical trade offs, and recommend solutions based on business needs, performance, security, and maintainability.
• Participate actively in architecture reviews and technical decision making alongside Architects and engineering teams.

API Design & System Integration

• Define and document API contracts, integration specifications, and communication patterns between internal and external systems.
• Work with RESTful APIs, gRPC, WebSockets, and asynchronous messaging technologies.
• Design event-driven integrations using messaging platforms such as NATS, Kafka, RabbitMQ, or similar technologies.
• Define message structures, event schemas, data contracts, validation rules, and error-handling mechanisms.
• Ensure appropriate consideration of idempotency, consistency, retry strategies, fault tolerance, and backward compatibility.
• Collaborate with data and backend engineers to ensure integration designs are technically feasible and aligned with platform standards.
• Analyze and design systems supporting banking products, financial transactions, and related operational processes.
• Work with financial concepts including customer accounts, payments, transaction processing, balances, fees, reconciliation, and financial reporting.
• Support the integration of core banking systems, payment providers, card processing platforms, and other financial services.
• Understand and document complex transaction lifecycles, business rules, financial data flows, and operational dependencies.
• Ensure proposed solutions appropriately address financial data integrity, auditability, security, and applicable regulatory requirements.
• Collaborate with Compliance, Risk, and Security teams on requirements affecting financial operations.
• Define logical data models, data structures, and information flows between systems and services.
• Collaborate with Data Engineering teams on data contracts, event structures, and operational data consumption.
• Understand relational and non-relational databases, data consistency principles, and distributed data management.
• Ensure system designs support data integrity, traceability, and reliable information exchange.
• Contribute to the design of data flows supporting real-time processing, operational reporting, and analytical capabilities.

Technical Documentation & Specifications

• Create and maintain high-quality technical documentation, including:
• Functional and technical specifications
• System interaction and sequence diagrams
• API and integration specifications
• Data flow diagrams and logical data models
• Business process models
• Use cases, user stories, and acceptance criteria
• Architecture decision records and technical design documentation
• Use appropriate modelling approaches where applicable.
• Maintain documentation that is clear, practical, and sufficiently detailed to support development, testing, maintenance, and future system evolution.

Engineering Collaboration & Delivery

• Work closely with data and backend engineers throughout implementation, providing technical clarification and resolving requirements related questions.
• Participate in technical discussions, solution reviews, and complex problem solving activities.
• Review implemented solutions against approved functional and technical requirements.
• Support QA engineers in defining test scenarios, acceptance criteria, and complex integration test cases.
• Investigate functional defects, integration issues, and unexpected system behaviour.
• Support technical planning, task decomposition, dependency analysis, and effort estimation.
• Maintain active involvement throughout the complete software development lifecycle.

Technical Leadership & Continuous Improvement

• Act as a technical authority for systems analysis practices across engineering teams.
• Establish and promote standards for requirements engineering, technical specifications, system modelling, and integration design.
• Lead complex cross team analysis initiatives involving multiple services, business domains, and external integrations.
• Proactively identify architectural weaknesses, technical debt, inefficient processes, and opportunities for improvement.
• Constructively challenge existing approaches and propose simpler, more effective technical solutions.
• Evaluate emerging technologies, architectural patterns, and engineering practices where they offer measurable value.
• Take end to end ownership of analysis and solution design activities with minimal supervision.
