11886 - Sr. Enterprise Architect

The Impact of a Sr Enterprise Architect at Coupa:

Owns the technical design and governance of Coupa's custom connector and MCP server portfolio. Sets the architecture standards agentic AI systems use to reach internal and third-party systems securely and at scale, and provides hands-on technical leadership to the integration engineering team.

What You'll Do:

• Define reference architecture for MCP servers and custom connectors: transport (stdio/SSE/streamable HTTP), auth, schema/versioning, error semantics, observability.
• Design and review connector specifications for internal systems (Coupa platform, NetSuite, SAP, Workday, Salesforce) and external partner APIs.
• Establish security and governance patterns: OAuth2/OIDC flows, credential/secrets management, least-privilege scoping of agent tool access, audit logging.
• Own the technical roadmap and backlog prioritization for the integration team in partnership with the Sr. Director.
• Provide architecture review and code-level guidance to AI Integration Engineers; unblock design decisions.
• Evaluate and select platform components (iPaaS, orchestration frameworks, agent SDKs, API gateways) for scalability and maintainability.
• Define and enforce testing/eval standards for connector reliability and agent tool-calling correctness.
• Act as technical escalation point for production incidents involving connectors/MCP infrastructure.
• Partner with Security, Data Governance, and Enterprise Architecture on compliance requirements (SOC 2, data residency, PII handling).

What You Will Bring to Coupa:

• 8+ years in software/integration engineering, including 3+ years in an architect or technical lead role.
• Deep hands-on experience building API integrations/connectors at enterprise scale (REST, GraphQL, gRPC, webhooks, event streaming).
• Working knowledge of MCP (Model Context Protocol) or comparable agent-tool-calling frameworks; understands transport, schema, and session-lifecycle tradeoffs.
• Strong command of at least one of Python, TypeScript/Node.js, and proficiency reading the other.
• Practical experience with LLM/agent frameworks (Anthropic/OpenAI SDKs, LangChain/LangGraph, or equivalent) and tool-calling design patterns.
• Solid grounding in identity/auth (OAuth2, OIDC, SAML), API security, and secrets management (Vault, AWS/GCP secret managers).
• Cloud platform experience (AWS, GCP, or Azure) and containerization (Docker/Kubernetes).
• Experience with enterprise systems integration (ERP, finance, procurement) - Coupa, NetSuite, SAP, or similar is a strong plus.
• Excellent written communication in English; able to produce architecture docs and lead design reviews with US/global stakeholders.
