Enterprise IT Architect / IT Solutions Architect

TISA is looking for an experienced IT Architect to help our organization make our work smooth. You will join to our team with also experienced co-workers and will be in many projects.

We are working on a long-term project for a global sports organization, focusing on the maintenance and development of an extensive event platform running on Microsoft Azure infrastructure. The system supports international-scale processes, ranging from data management to complex integrations with external vendors.
The project is mature and highly complex, with over a decade of history, a database containing more than 400 tables, and a sophisticated integration ecosystem.

Key Responsibilities

• Designing and documenting IT solution architecture at an enterprise level (system diagrams, data flows, integration descriptions).

• Creating and maintaining Architecture Decision Records (ADRs) – justifying why a particular solution was chosen, not just how it works.

• Analyzing business and technical requirements and translating them into architectural concepts aligned with the existing ecosystem.

• Assessing existing systems, identifying architectural risks, and recommending future development directions.

• Defining integration standards with external systems (REST API, event-driven, webhooks) and ensuring their consistency.

• Verifying compliance of implemented solutions with corporate architecture, security, and quality standards.

• Collaborating with the development team to solve complex technical problems and provide architectural guidance.

• Advanced, hands-on knowledge of Microsoft Azure – App Service, Azure Functions, Service Bus / Event Hub, Azure SQL, API Management, Azure DevOps (minimum 3 years of real-world experience).

• Proven experience in designing cloud architecture at an enterprise level.

• Practical knowledge of architectural and integration patterns: event-driven architecture, SOA, API-first, microservices vs. monoliths.

• Experience with large, complex relational databases (data modeling, query optimization, dependency management).

• Understanding of security and resilience in distributed systems (circuit breaker, retry, idempotency, SLA/SLO/RPO/RTO).

Documentation & Communication

• Experience in creating architectural documentation: UML / C4 diagrams, Architecture Decision Records (ADRs), interface and data flow descriptions.

• Ability to communicate technical concepts effectively to both development teams and business stakeholders.
