About the role

Tata Consultancy Services (TCS) is hiring an experienced, hands-on Solution Architect in Sydney to support delivery across its Regulatory technology portfolio. The architect works with architecture leads, technical business analysts, delivery teams, engineers, platform teams and vendors to turn business requirements and architecture direction into detailed, buildable solution designs. Candidates must be comfortable working directly with engineering teams, understanding existing systems, defining interfaces and producing the architecture and technical design artefacts needed for delivery.

Key responsibilities

• Define REST API specifications, request/response models, schemas, error models and interface contracts, and produce OpenAPI / Swagger specifications.
• Develop system context, component, integration, sequence, data-flow and deployment diagrams, and define synchronous and asynchronous integration patterns.
• Define API, event, messaging, batch and file interfaces, and work with engineering teams to define microservice boundaries, responsibilities and contracts.
• Analyse impacts to legacy systems and define coexistence, transition, migration, cutover, rollback and reconciliation approaches.
• Work with IAM and Security teams on authentication, authorisation and security requirements, and define non-functional requirements such as availability, resilience, performance, scalability, observability and recoverability.
• Support Technical BAs in translating business, business rules and regulatory requirements into technical requirements, and lead technical design workshops with delivery teams and vendors.
• Take part in backlog refinement, review detailed designs and resolve solution and integration issues during delivery.
• Maintain architecture decisions, assumptions, dependencies, risks and deviations, and prepare artefacts for review and feedback.
• Support integration testing, release readiness, cutover and operational transition, keeping architecture artefacts up to date as the solution evolves.
