Integration Architect

Description

Job Summary: We are seeking an Integration Architect with end-to-end vision and technical decision-making capability to define, evolve, and govern corporate integrations within the People-Tech/HR domain, in an international and demanding environment. Key Highlights: 1. Influence platform, governance, and interoperability decisions at a global level 2. Technical leadership in end-to-end strategic integrations 3. Work with cutting-edge technologies such as MuleSoft and Kafka DESCRIPTION At SG Tech, we drive technological evolution for organizations by connecting business, data, and technology through a flexible, agile, and impact-oriented approach. With over 25 years of experience, we develop tailored solutions and champion talent, continuous learning, and professional growth within highly demanding technical environments. Our work model combines specialization, proximity, and adaptability to support complex digital transformation challenges from start to finish. We are looking for an Integration Architecture profile with end\-to\-end vision and strong technical decision-making ability to define, evolve, and govern corporate integrations within the People\-Tech / HR domain. This position targets professionals with proven experience in architectural design—not merely implementation—who can establish integration standards, evaluate technical trade\-offs, and ensure that integration flows comply with security, traceability, and data protection requirements in enterprise contexts. The selected candidate will operate in an English-speaking international environment, collaborating closely with product, platform, HR tech specialist teams, and consuming squads. They will play a key role in defining synchronous and asynchronous integration patterns, designing API\-first and event\-driven architectures, providing technical governance for the domain, and evolving a scalable, observable, and secure architecture built on MuleSoft Anypoint Platform. Key responsibilities include designing integration architectures on MuleSoft; defining OpenAPI 3\.x and AsyncAPI 2\.x contracts; providing technical leadership for end\-to\-end strategic integrations; implementing observability and security standards; documenting architectural decisions via ADRs and diagrams; and mentoring junior profiles on integration best practices and API design. The candidate will also play a significant role in coordinating with cross-functional teams to align technical decisions, facilitate consensus, and ensure compliance with HR data protection policies. This is an excellent opportunity for an architecturally senior profile seeking to influence platform, governance, and interoperability decisions within a global, demanding, and functionally complex context. At SG Tech, we especially value individuals who combine sound technical judgment, effective communication skills, and a focus on building robust, sustainable, and scalable solutions.
