IT Architect  – Middleware/Integration

We have an immediate start day rate contract for  an experienced Middleware and Integration Architect  with Audit and Gap Analysis experience. The ideal candidate will be comfortable evaluating systems and providing deep architectural insights and identifying strategic opportunities for improving resilience, scalability, and maintainability.

Key Responsibilities

• Conduct a comprehensive audit of our client’ eESB (Enterprise Service Bus) platform against defined non-functional criteria (resilience, SPOF, scalability, DDoS exposure, platform sizing).
• Review the end-to-end technical architecture across messaging, file transfer, and data streaming services.
• Perform gap analysis against enterprise-grade middleware standards and emerging integration patterns.
• Evaluate our client’ current tech stack (Spring Boot, Apache Camel, Artemis, Kafka, Kubernetes, Azure DevOps, Terraform, Vault, etc.) for technical debt, obsolescence, or operational risk.
• Assess high-availability, disaster recovery, and observability models in place.
• Identify single points of failure in Kubernetes and VM-based deployments and propose at least two mitigation strategies.
• Develop recommendations and future-state architecture options, including high-level effort and cost estimates.
• Collaborate with the project manager to deliver structured outputs in both Excel (for RFQ) and PDF (for technical narrative).
• Present findings to both technical and non-technical stakeholders in a clear, structured manner.

Required Experience & Skills

• 10+ years in IT architecture, with specific focus on enterprise integration, middleware platforms, and audit/assessment engagements.
• Strong understanding of Enterprise Integration Patterns (EIP) and asynchronous communication models.
• Demonstrated success conducting gap analyses or resilience audits in complex IT environments.
• Familiarity with zero-trust architectures, NIST security frameworks, and DDoS mitigation strategies.
• Experience with observability stacks (Grafana, ELK) and performance tuning.
• Exceptional communication skills with ability to translate technical risks into business impact.
