🎯 Role Definition

The Integration Architect is a senior technical leader responsible for designing, delivering, and governing enterprise integration solutions that connect applications, data streams, APIs, and cloud services. This role combines domain knowledge of integration patterns, middleware platforms, and security with pragmatic delivery experience across on-premises and cloud-native systems. The Integration Architect partners with product and engineering teams, stakeholders, and operations to define reusable integration frameworks, API strategies, and integration governance to accelerate time-to-market and reduce technical debt.

Core Responsibilities

Primary Functions

  • Design and document enterprise integration architectures, including API gateway patterns, ESB topologies, message broker landscapes, event-driven architectures (EDA), and data integration pipelines, ensuring alignment with business goals and technical constraints.
  • Define and enforce API strategy, lifecycle, versioning, and governance standards (REST/JSON, GraphQL, gRPC, SOAP), including security patterns (OAuth2, JWT, mTLS) and scalable throttling/quotas.
  • Lead the selection, evaluation, and deployment of middleware solutions and Integration Platform as a Service (iPaaS) tools such as MuleSoft, Dell Boomi, TIBCO, WSO2, or Azure Integration Services to meet enterprise needs.
  • Architect event-driven patterns with Kafka, Pulsar, or RabbitMQ for asynchronous integration, schema governance (Avro/Protobuf), and cross-service data streaming to enable real-time use cases.
  • Create reusable integration components, templates, and accelerators (connectors, mappings, transformation libraries) to accelerate delivery and drive consistency across projects.
  • Translate complex business processes into robust integration flows and message-routing logic, designing canonical data models and transformation mappings for enterprise data consistency.
  • Collaborate with security, compliance, and identity teams to design secure integration patterns (API gateways, identity federation, encryption in transit and at rest, secrets management).
  • Design high-availability, disaster recovery, and fault-tolerant integration topologies with capacity planning, failover strategies, and recovery time objectives (RTO/RPO).
  • Define monitoring, observability, and alerting requirements for integration platforms, including metrics, tracing, logging (OpenTelemetry), and runbook development to support SRE and ops teams.
  • Establish CI/CD pipelines and Infrastructure as Code (IaC) best practices for integration artifacts using tools like Jenkins, GitLab CI, Terraform, or ARM templates to support repeatable automated deployments.
  • Provide hands-on guidance and code-level reviews for integration teams, including mentoring engineers on best practices for API design, message patterns, error handling, and retry semantics.
  • Lead proof-of-concepts and migration strategies to move legacy point-to-point integrations into modern, governed integration platforms or microservice-based solutions.
  • Define data contract and schema evolution strategies, including backwards-compatible changes, contract testing, and consumer-driven contracts for APIs and event streams.
  • Manage cross-functional integration roadmaps, coordinate dependencies across application teams, and prioritize technical debt related to integration and middleware.
  • Create and maintain architecture diagrams, interface catalogs, integration inventories, and interface-level SLAs to provide transparency and reduce hidden coupling between systems.
  • Partner with product owners and business stakeholders to define non-functional requirements (latency, throughput, scalability) and translate them into integration architecture decisions.
  • Lead vendor relationships and third-party integrations, including assessment of SLAs, security posture, and integration complexity for SaaS and external partners.
  • Define B2B/EDI onboarding processes, mapping guidelines, and certificate/exchange management for partners with secure file transfer and message exchange requirements.
  • Conduct regular architecture reviews, risk assessments, and technical debt remediation plans focused on integration landscapes and cross-domain impacts.
  • Ensure compliance with corporate architecture standards and regulatory requirements when designing integrations for finance, healthcare, or other regulated domains.
  • Drive cost optimization and cloud consumption best practices for integration workloads, including serverless integration options, managed services, and containerized middleware.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis.
  • Contribute to the organization's data strategy and roadmap.
  • Collaborate with business units to translate data needs into engineering requirements.
  • Participate in sprint planning and agile ceremonies within the data engineering team.
  • Promote knowledge sharing by creating playbooks, runbooks, and internal training sessions on integration patterns and tool usage.
  • Assist procurement and legal teams with technical evaluation of third-party integration vendors and SLAs.
  • Review and approve integration-related change requests and design decisions during release cycles.
