Job Summary

The Agentic Integration Architect connects enterprise systems, data, and AI. The role designs API, event-driven, messaging, cloud, and hybrid integration architectures, and builds MCP, AI Gateway, AI agent, and LLM-enabled integration solutions on top of them. It brings deep hands-on expertise in one or two integration platforms (MuleSoft, Kong, Boomi, Azure Integration Services, Kafka, or Workato), with working knowledge across the wider integration landscape.

As a CoE role, it defines reference architectures, frameworks, accelerators, governance, and best practices, evaluates emerging technology through PoCs, shapes integration strategy, creates architecture and thought-leadership assets, and mentors teams. It also supports Solutions and Advisory teams with expert input to workshops and proposals.

Design API, event-driven, messaging, cloud and hybrid integration architectures; build MCP, AI Gateway, AI Agent and LLM-enabled integration solutions; deep hands-on expertise in one or two of MuleSoft, Kong, Boomi, Azure Integration Services, Kafka or Workato, with working knowledge across the broader integration landscape; define reference architectures, frameworks, accelerators, governance and best practices; evaluate emerging technology and build PoCs; shape integration strategy; create architecture and thought-leadership assets; mentor teams and support workshops and proposals. Mandatory across all roles: practical AI-native engineering; strong modern application development; cloud-native, API, microservices and DevSecOps grounding; hands-on experience with at least one agent harness such as Claude Code, GitHub Copilot, Codex, Kiro or Cursor; enterprise security, governance, evaluation, observability and cost awareness.

Key Responsibilities

A. Integration Architecture

  • Design API, event-driven, messaging, cloud, and hybrid integration architectures (on-premises, multi-cloud, SaaS, and legacy).
  • Define API strategy and lifecycle: design-first, versioning, contracts, catalogs, discoverability, and API products.
  • Design event and messaging architectures: topics, schemas and schema evolution, ordering, delivery guarantees, idempotency, replay, dead-letter handling, and event governance.
  • Apply integration patterns (orchestration vs. choreography, saga, CQRS, outbox, strangler, canonical models) with appropriate resilience and error handling.

B. AI-Enabled Integration

  • Build MCP servers and gateways that expose enterprise APIs, events, and data to AI agents safely and consistently.
  • Design AI Gateway capabilities: model routing and failover, authentication and quotas, rate limiting, token and cost controls, caching, prompt and response policies, guardrails, and audit logging.
  • Build AI agent and LLM-enabled integration solutions, such as intelligent mapping and transformation, document and message classification, event enrichment, and agent-driven orchestration across systems.
  • Design agent-to-system integration patterns: tool contracts, idempotency, scoped credentials, approval gates, and safe retries.

C. Platform Expertise

  • Provide deep, hands-on architecture and build leadership on one or two of MuleSoft, Kong, Boomi, Azure Integration Services, Kafka, or Workato.
  • Maintain working knowledge across the broader landscape (API gateways and management, iPaaS, ESB/legacy middleware, streaming platforms, service mesh, cloud-native integration services, B2B/EDI) and guide platform selection and coexistence.
  • Architect hybrid connectivity, networking, and security (private links, VPN, zero-trust, API security) for integration workloads.

D. Reference Architectures, Governance & Accelerators

  • Define reference architectures, frameworks, and accelerators: API and event templates, MCP server and gateway templates, AI gateway policy packs, connector libraries, and CI/CD pipelines for integration assets.
  • Establish governance and best practices: API and event standards, schema and contract governance, lifecycle management, security policies, and an integration operating model.
  • Define evaluation, observability, security, and cost controls for integrations and AI-enabled flows (contract testing, tracing, SLOs, least privilege, token and platform cost management).

E. Innovation & Proofs of Concept

  • Evaluate emerging technology (MCP and agent interoperability protocols, AI gateways, platform AI features, streaming and event standards) and recommend where it fits.
  • Build PoCs that prove feasibility and value; convert successful PoCs into reusable assets and delivery-ready patterns.
  • Use AI-native engineering and agent harnesses to build and iterate quickly while maintaining production quality.

F. Integration Strategy & Engagement Support

  • Shape integration strategy: target architecture, platform rationalization, API and event maturity roadmaps, and AI-readiness of the integration layer.
  • Provide expert architecture input to customer roadmaps, workshops, and demos led by Solutions and Advisory teams.
  • Contribute architecture content, estimation inputs, and risk framing to proposals and pursuits.
  • Turn field feedback and engagement learnings back into CoE frameworks and accelerators.

G. Thought Leadership & Mentoring

  • Create architecture and thought-leadership assets: whitepapers, point-of-view documents, reference diagrams, blogs, and briefing material.
  • Mentor engineers and architects; build capability across integration platforms and AI-enabled integration; contribute to training and certification pathways.

Skill Requirements

  • Bachelor's or Master's degree in Computer Science, Engineering, Information Systems, or an equivalent field, or equivalent practical experience.
  • 12+ years in software or integration architecture, with at least 6 years on one or more of the named integration platforms and at least 2 years building LLM-based, agent, or AI-enabled integration solutions.
  • Track record of delivering enterprise-scale API, event-driven, or hybrid integration programs, and of supporting field teams in customer workshops or proposals.

Technical Skills (Must Have)

  1. API architecture: REST, GraphQL, gRPC, AsyncAPI/OpenAPI, API lifecycle management, security (OAuth2/OIDC, mTLS), and API product thinking.
