In this role, you will serve as a key technical leader for our mission-critical identity and access platform, partnering with other engineering leaders and cross-functional teams to ensure its success. Because this core system underpins all of Pattern's operations, you will partner closely with a wide variety of cross-functional teams to field, prioritize, and build a high volume of feature requests while ensuring the ongoing maintenance, stability, and high performance of existing applications.

You are seen and trusted as a primary subject matter expert and partner for central Auth/Authz and admin tooling across all of Pattern.

You strike an effective balance between rapidly delivering requested features for partner teams and systematically maintaining/refactoring existing applications to ensure system stability and reliability while preventing technical debt.
