Integration Architect; (m​/w​/d

We are looking for an Integration Architect (100%) for one of our clients in Geneva.

Start date:

30 July 2026

End date: 4 months after the start date

Location:

onsite at Geneva or remote.

We are seeking an Integration Architect to define the integration patterns and interface design for a platform connecting AI systems, centralized orchestration services, and external partners. The role is responsible for defining how systems interact at scale, ensuring robust, secure, and performant system integration across multiple interfaces and protocols.

• Define the end-to-end integration architecture, covering interactions between AI platforms, orchestration, ensuring interoperability across multiple integration paradigms
• Establish the API and MCP integration strategy, including:
  • Definition of the AI-facing MCP exposure layer
  • Standardized approach for API connectivity (proprietary and NDC/Offer & Order)
  • API lifecycle principles (versioning, governance, reuse)
• Define orchestration and routing patterns to support:
  • Aggregation of responses across MCP, APIs and industry standards
  • Traffic control, optimization, and support for both synchronous and asynchronous patterns
• Specify integration interaction with the caching layer, including:
  • Retry, fallback, and resilience behavior
  • Alignment with required data access and performance patterns
• Define a multi-standard integration approach that:
  • Enables connectivity with clients own MCP servers, proprietary APIs and industry-standard APIs
  • Provides a unified abstraction layer for AI interaction via MCP
  • Avoids point-to-point integrations through reusable patterns
• Establish security, control, and resilience principles, including:
  • Authentication and authorization models
• Define the technology and governance framework for integration, including:
  • Evaluation criteria for API gateways, middleware, and messaging solutions
  • Architectural guardrails for implementation teams
  • Validation principles for vendor and partner integration designs
• Ensure the overall design delivers a single, coherent integration layer, enabling AI-native interactions, orchestrating heterogeneous systems, and supporting future scalability

• Integration architecture documentation
• Interface / API specifications and mappings
• Orchestration and interaction patterns
• Integration decision logs

• 5+ years of experience in integration architecture or solution architecture
• Strong experience with API design and integration patterns
• Experience with distributed systems and high-volume transaction environments
• Familiarity with REST APIs, event-driven architectures, and system orchestration
• Exposure to cloud-based architectures and MCP (e.g., AWS or similar)
• Strong analytical and stakeholder communication skills
