The Job

Job Summary:

We are seeking a Technical Architect to design a large-scale platform spanning multiple products, business domains, and shared services, with strong requirements for software quality, reliability, security, and scalability.

The project follows an AI-first approach across analysis, architecture, review, and implementation. The Technical Architect structures work for AI-assisted execution while retaining ownership of architectural decisions and validating the quality of all deliverables.

Analyze business domains and define service boundaries, data ownership, and cross-service dependencies.

Review business and technical contracts to identify gaps, inconsistencies, and risks before detailed design.

Design service, database, API, event, and integration architectures, ensuring shared capabilities are reused across products.

Produce architecture specifications and implementation contracts that enable developers and AI coding agents to implement solutions consistently.

Design for scalability, security, resilience, observability, testing, and deployment appropriate to each delivery phase.

Apply AI-first workflows through structured context, task decomposition, reusable skills, and validation gates.

Review AI-generated documentation and code for architectural compliance and traceability to requirements, contracts, and approved decisions.

Guide developers and collaborate with Business Analysts, QA, DevOps, and Security teams.

Assess the impact of changes to requirements, contracts, and architecture.

Solid understanding of data modeling, transaction boundaries, consistency, concurrency, idempotency, and failure handling.

Experience designing multi-tenant systems with complex integrations, high availability, and horizontal scalability.

Strong backend engineering experience with Java/Kotlin, Spring Boot, relational databases, messaging, and API design.

Working knowledge of cloud architecture, containers, CI/CD, observability, security, and disaster recovery.

Practical experience using AI tools for technical work and willingness to follow an AI-first development workflow .

Ability to validate AI outputs against authoritative sources, architecture reviews, and automated tests, and identify unsupported assumptions or conclusions.

Experience building platforms or ecosystems serving multiple products and business domains.
