B2B • Recruitment

HumanIT Digital Consulting is a human-centered digital consulting and talent services firm that helps organizations find, onboard and grow people while delivering digital transformation and IT-related consulting. The company emphasizes people-first values and offers services to both jobseekers and hiring companies across offices in Portugal and Switzerland. HumanIT positions itself as a partner for businesses seeking human talent and for professionals seeking career opportunities in digital and IT roles.

📋 Description

• You'll be embedded in the IT Operational Excellence Department (IT OPEX) — the centralised control point for IT strategy, governance, and standards across a scaling product landscape. • Your mandate is to fill a critical architectural gap: while ESB/middleware teams handle inter-domain routing, you take definitive ownership of intra-domain architecture and local system communications, ensuring decentralised product teams build integrations that are scalable, secure, and consistent — eliminating brittle point-to-point connections and preventing technical debt before it accumulates.

🎯 Requirements

• 7+ years of deep technical experience in enterprise application integration, API management, and event-driven architectures within complex, multi-system corporate environments • Advanced mastery of modern integration paradigms: REST, GraphQL, gRPC, and Event Brokers (e.g., Kafka, RabbitMQ) in production enterprise contexts • Strong working knowledge of ESB/middleware platforms — specifically webMethods or equivalent (IBM Integration Bus, MuleSoft, etc.) • Familiarity with cloud-native ETL and data integration tooling such as Azure Data Factory, Azure Integration Services, or equivalent • Proven ability to design, publish, and govern enterprise integration patterns — API-first, event-driven, microservices — and enforce adoption across decentralised engineering teams • Hands-on experience enforcing architectural guardrails such as the Signal vs. Payload pattern, ensuring large file transfers are decoupled from real-time ESB operations • Demonstrated experience defining operating models and rules of engagement across separate architectural and infrastructure delivery teams • Track record of technical debt mitigation — reviewing product team designs proactively and providing actionable guidance before problems reach production • Ability to operate as a community leader — driving standards adoption across engineering squads without direct hierarchical authority • Strong capacity to navigate both high-level business strategy and deep technical system-to-system data flows simultaneously • Clear, confident communication in English (B2 or above) — essential for cross-functional stakeholder engagement at all levels
