## Description

We are looking for a Senior HubSpot Platform Engineer to own and evolve a customized HubSpot environment that serves as the central operating system for our Sales, Marketing, Partner Management, and After-Sales operations across 6 international regions. Our platform includes custom-developed UI Extensions (React), a CMS-based Partner Portal, multiple Custom Objects with complex association logic, 100+ interdependent workflows, a custom-built CPQ process, and bidirectional integrations with several external systems.

You will be the go-to person for everything from CRM configuration and workflow automation to portal development and custom app maintenance. This role requires someone who can move fluidly between disciplines - from writing HubL templates to debugging React components to designing workflow cascades.

You'll get to take ownership of:

 * CRM Architecture: Configure and maintain Custom Objects, Association Labels, Pipelines, and Properties across a complex, multi-object data model
 * Workflow Automation: Build and maintain complex workflows including Custom Code Actions (JavaScript), cross-object property sync, and multi-level approval chains
 * UI Extension Development: Develop and maintain custom-built React-based UI Extensions (CPQ tool, deal configuration, link cards) deployed via HubSpot Serverless Functions
 * Partner Portal: Develop and maintain an external HubSpot CMS-based Partner Portal with membership logic, visibility rules, and HubDB-driven content
 * Integrations: Support and extend API integrations with external systems (ERP, LMS, support tools, AI services) via Operations Hub and custom code
 * Documentation: Maintain technical documentation for configurations, custom code, and integrations
