Principal Enterprise Integration Architect – ESB, API, Event-Driven

This is a fully remote position, open to applicants in Portugal.

📋 Description

• You will be integrated into the IT Operational Excellence Department (IT OPEX) — the centralized hub for IT strategy, governance, and standards within a growing product ecosystem.

• Your role is to address a vital architectural void: while ESB/middleware teams manage inter-domain routing, you will assume definitive responsibility for intra-domain architecture and local system communications. This ensures that decentralized product teams construct integrations that are scalable, secure, and consistent — thereby eliminating fragile point-to-point connections and preventing the accumulation of technical debt.

⛳️ Requirements

• Over 7 years of extensive technical experience in enterprise application integration, API management, and event-driven architectures within intricate, multi-system corporate settings.

• Advanced expertise in contemporary integration paradigms: REST, GraphQL, gRPC, and Event Brokers (e.g., Kafka, RabbitMQ) in live enterprise environments.

• Solid working knowledge of ESB/middleware platforms — particularly webMethods or its equivalents (IBM Integration Bus, MuleSoft, etc.).

• Familiarity with cloud-native ETL and data integration tools such as Azure Data Factory, Azure Integration Services, or similar solutions.

• Proven capability to design, publish, and govern enterprise integration patterns — API-first, event-driven, microservices — and ensure adherence across decentralized engineering teams.

• Hands-on experience in enforcing architectural guardrails such as the Signal vs. Payload pattern, ensuring that large file transfers are decoupled from real-time ESB operations.

• Demonstrated experience in defining operating models and rules of engagement among distinct architectural and infrastructure delivery teams.

• A history of mitigating technical debt — proactively reviewing product team designs and offering actionable guidance before issues escalate to production.

• Ability to serve as a community leader — promoting standards adoption across engineering teams without direct hierarchical authority.

• Strong aptitude for navigating both overarching business strategies and intricate technical system-to-system data flows simultaneously.

• Clear and confident communication in English (B2 or above) — crucial for engaging with cross-functional stakeholders at all levels.
