- Work closely with Security and Identity teams to enforce secure access patterns (OAuth2, OIDC, API keys, SSO) for all partner integrations.
- Partner with Product and Platform teams to define integration blueprints and streamline onboarding via portals and marketplaces.
- Support partner onboarding flows for cloud and SaaS ecosystems, including technical integration and listing requirements.
- Contribute to developer experience improvements — including examples, templates and documentation for SDKs and plugins.
- Ensure observability, monitoring and alerting are integrated into all plugins and connectors.
- Stay ahead of trends in cloud marketplaces, conversational AI and integration platforms and propose new integrations to the roadmap.
