About the role

  • In this position, you will partner closely with Engineering, Product, and Services teams to design and own the end-to-end identity architecture that underpins our Exchange's security, scalability, and interoperability.
  • The Senior/Principal Identity and API Architect plays a critical role in driving TripleLift's identity infrastructure and API security strategy within the Exchange team, directly influencing how we authenticate and authorize publishers, buyers, and platform partners across our programmatic marketplace.
  • This is an exciting opportunity for someone who wants to build a best-in-class identity platform from the ground up, shaping how TripleLift authenticates billions of programmatic transactions while serving as a strategic thought partner to Exchange leadership on API governance and access control.

Responsibilities

  • Architect and own TripleLift's end-to-end identity platform, including tenant models, SSO integrations, machine-to-machine authentication, and delegated administration for publishers and demand partners.
  • Design and implement Auth0 tenant architecture, including custom domains, enterprise connections, Actions/Rules, and token lifecycle management (refresh rotation, session policies, JWKS).
  • Build and operate multi-tenant authorization models using OpenFGA or comparable ReBAC systems (e.g., SpiceDB, Ory Keto), enabling fine-grained access control across publisher hierarchies (networks,, seats, users).
  • Own the API gateway layer, designing rate limiting, scoped token validation, mTLS enforcement, and consistent error semantics across Traefik, Kong, AWS API Gateway, or equivalent infrastructure.
  • Lead publisher-side identity integrations, including federated SSO (SAML 2.0, OIDC) for enterprise onboarding, delegated self-service administration, and integration of first-party data and authenticated traffic signals into programmatic decisioning.
  • Lead demand-side identity integrations, including DSP and agency API authentication (OAuth 2.0 M2M, API key management), partner onboarding flows, and identity traceability across bid request/response flows for audit, fraud detection, and deal enforcement.
  • Manage AWS identity and API infrastructure, including IAM roles and cross-account trust, Cognito integration patterns, Secrets Manager and KMS for credential lifecycle, and STS-based service-to-service auth in multi-account environments.
  • Establish and maintain identity and API security standards, conducting threat modeling, reviewing integrations for compliance with RBAC/ABAC/ReBAC policies, and responding to security incidents.
  • Mentor engineers across the Exchange team on identity best practices, OAuth/OIDC protocol nuances, and secure API design patterns.
  • At TripleLift, we are committed to building a culture where people feel connected, supported, and empowered to do their best work.

Requirements

  • 2+ years of hands-on production experience with Okta's Auth0, including:
