Job description

Solution Designer -

Main Responsibilities

• Lead solution design for complex business capabilities across microservices, APIs, data flows, and enterprise integrations
• Elicit and analyse business, functional, and non-functional requirements; translate them into clear solution blueprints
• Produce high-quality design artefacts: context diagrams, sequence diagrams, data models, API contracts, integration patterns, and decision records
• Define target-state and transition-state architectures in partnership with Enterprise / Domain Architects
• Ensure designs meet non-functional requirements: security, resilience, performance, scalability, observability, and operability
• Design integrations with upstream/downstream systems (ERP, AP, tax/compliance, document stores, event streams, and third-party platforms)
• Guide engineering teams through design walkthroughs, design reviews, and implementation trade-offs
• Identify risks, gaps, and dependencies early; propose pragmatic mitigation and sequencing
• Align solutions to Cloud First, API-first, event-driven, and microservices patterns where appropriate
• Contribute to estimation, delivery planning, and technical readiness for releases
• Mentor developers and analysts on design thinking, patterns, and documentation quality
• Collaborate with Security, Risk, and Compliance stakeholders to embed controls into the design
• Fulfil other tasks as assigned by your People Leader and/or authorised representative of NAB Innovation Centre India from time to time

What You Will Bring Skills and Experience

Must-have

• 810 years total IT experience, with substantial hands-on solution design / application architecture across enterprise systems
• Proven ability to design end-to-end solutions spanning UI/API, services, data, and integrations
• Strong experience with microservices, REST APIs, event-driven architectures, and integration patterns (sync/async, pub-sub, orchestration vs choreography)
• Solid understanding of Java / Spring Boot (or equivalent enterprise stack) and how designs map to implementable code
• Experience with cloud platforms — preferably AWS — and Cloud First design considerations (compute, networking, storage, IAM, managed services)
• Strong modelling and documentation skills (UML / C4 / sequence / data flow); comfortable using tools such as Confluence, Visio, Lucidchart, PlantUML, or similar
• Experience with OpenAPI / Swagger-first API design and contract testing strategies
• Experience designing for security and compliance (authN/authZ, least privilege, auditability, data protection)
• Ability to engage stakeholders at business and technical levels; strong facilitation and communication skills
• Agile delivery experience; ability to work in iterative increments while protecting architectural integrity
• Tertiary qualification in a technology-related discipline (or equivalent experience)

Nice to have

• Banking / financial services domain experience (procurement, invoicing, AP, payments, GST/tax, or similar)
• Exposure to domain-driven design (DDD), CQRS, and event sourcing concepts
• Experience with Kafka / messaging platforms and enterprise integration middleware
• Familiarity with Kubernetes, CI/CD, and operational runbooks from a design-for-ops perspective
