Note: The job is a remote job and is open to candidates in USA. Toppan Merrill is hiring a Senior AI Engineer, Platform Integration to build and own a secure integration service connecting external AI tools to its Quinn platform for legal and capital-markets disclosure workflows. The role focuses on OAuth-based authorization, document access controls, immutable audit logging, AI risk controls, and supporting client security reviews.
Responsibilities
- Productionize the integration service (an MCP server) that outside AI tools connect to, over the Streamable HTTP transport
- Implement sign-in with OAuth 2.1 using our identity provider (Okta), including token exchange so the service calls Quinn on behalf of the attorney and never passes an outside tool’s token through
- Enforce what each outside tool may do: which actions its permissions allow, and which documents are on each client firm’s approved list, denying everything else by default
- Keep an immutable, exportable audit trail of every action an outside tool takes, including reads, that client firms can review
- Design controls for AI-specific risks, including tool misuse driven by content in documents and abnormal bulk access to documents
- Test with at least two external AI tools, and support client firms’ security reviews
- Build an internal command-line tool for our operations teams on the same service
Skills
- 6+ years of backend or platform engineering
- Deep, hands-on OAuth 2.0 or 2.1 and OIDC experience: authorization servers, scopes, audience, PKCE, token exchange
- Experience building services that external customers or partners integrate with, including security reviews
- Security-first engineering habits: deny by default, least privilege, audit logging
- Strong in TypeScript (Node.js) or Python, and comfortable working in the other; our services use both
- Experience integrating with customers' identity providers (OIDC or SAML federation, multi-tenant SSO)
- Model Context Protocol (MCP) servers, or AI tool and agent integrations
- Okta administration or custom authorization servers
- Experience integrating with enterprise legal software (document management systems, Harvey, or similar)
Benefits
- Enhanced Medical, Dental, Vision and, Life insurance for employees and dependents
- Employer Contribution to 401(k)
- Paid time off including vacation, sick, community involvement, bereavement, jury duty, and holidays
- Paid parental leave
- Paid community involvement/volunteer days
