Senior Integration Architect

Are you an experienced Integration Architect passionate about designing scalable solutions, modernizing complex systems, and connecting technologies across enterprise environments?

We're looking for a Senior Integration Architect to join an international technology environment, working in a hybrid model .

This opportunity is ideal for someone who combines strong expertise in software architecture, microservices, API integration, and event-driven systems with a collaborative mindset and excellent communication skills.

You'll play a key role in defining integration strategies, modernizing legacy systems, and ensuring that technical solutions are scalable, secure, and aligned with business objectives.

🚀 What You'll Be Doing:

• Design Integration Architectures: Define and document scalable integration solutions, including logical and physical architectures, data flow diagrams, API contracts, and sequence diagrams.
• Drive Architecture Modernization: Analyze existing systems, perform reverse engineering of legacy applications, and identify dependencies, integration flows, and modernization opportunities.
• Define Technical Standards: Establish API versioning strategies, standardized data models (JSON Schema, Avro), messaging patterns, and error-handling mechanisms, including retry policies and Dead Letter Queues (DLQ).
• Develop Event-Driven Solutions: Design and structure event-driven architectures using Apache Kafka, ensuring reliable communication between distributed systems.
• Collaborate Across Teams: Work closely with product, engineering, security, and business stakeholders to design solutions that meet both technical and business requirements.
• Ensure Security & Governance: Promote architectural best practices, conduct technical design reviews, and ensure compliance with security, privacy, and integration standards.
• Improve Observability: Support monitoring and troubleshooting strategies using Datadog, including application performance monitoring, distributed tracing, and log analysis.
• Mentor & Share Knowledge: Support engineering teams through technical guidance, knowledge sharing, and the adoption of architecture best practices.

💻 What We're Looking For:

Architecture & Integration

• Strong experience designing modular architectures, microservices, and distributed systems .
• Solid understanding of software architecture principles, integration patterns, and system design.
• Hands-on experience defining and documenting REST APIs using Swagger / OpenAPI Specification .
• Proven ability to perform reverse engineering of complex legacy systems , identifying dependencies, business rules, and integration flows.
• Strong knowledge of Apache Kafka , including topic design, event modeling, and event-driven architecture.
• Experience defining API contracts, data models, and integration standards.

Cloud & Observability

• Working knowledge of Google Cloud Platform (GCP) , particularly:
• BigQuery: Analytical data processing and querying.
• Cloud Storage: Secure object storage and data management.
• IAM: Identity, access policies, roles, and permissions.
• Experience with Datadog for monitoring, application performance management (APM), distributed tracing, and log management.

Security & Access Management

• Solid understanding of API security and authentication standards, including OAuth2, OpenID Connect (OIDC), and API Keys .
• Experience with HashiCorp Vault for secrets management, credential protection, and rotation.
• Awareness of security, privacy, and governance best practices in enterprise integration environments.

Ways of Working

• Experience working in Agile environments, particularly Scrum and Kanban .
• Ability to collaborate with multidisciplinary teams and contribute to architectural decisions.

🤝 What Will Make You Stand Out:

Beyond technical expertise, we're looking for someone who genuinely enjoys working with people and making complex technology easier to understand.

• Teamwork & Collaboration: A collaborative mindset, empathy, and willingness to support colleagues and share knowledge.
• Holistic Thinking: Ability to understand the broader technology ecosystem and anticipate the impact of architectural decisions across interconnected systems.
• Communication Skills: Confidence translating business requirements into technical solutions and explaining architectural trade-offs to both technical and non-technical stakeholders.
• Stakeholder Management: Ability to align expectations, negotiate priorities, and build consensus between product, engineering, and security teams.
• Technical Leadership: A constructive approach to architectural discussions, mentoring, and continuous improvement.

🌍 What You Can Expect:

• A hybrid working model , combining flexibility with opportunities for face-to-face collaboration.
• The opportunity to work in an international, multidisciplinary technology environment.
• Involvement in challenging integration and modernization initiatives.
• The chance to influence architectural decisions and contribute to technical standards.
• A collaborative culture that values knowledge sharing, teamwork, and continuous learning.
