As CRM Sr. Manager, Architect & Journeys Developer, you will be the technical engine behind our clients' lifecycle programs. You will turn CRM strategy into working CRM solutions: blueprinted data models, automated journeys, and personalized campaigns that drive retention and customer lifetime value.
This is a hands-on, senior build role. You will architect and develop journeys in Journey Builder and Automation Studio, write AMPscript and SQL, and design the data structures that power personalization at scale. If you have experience translating customer journey maps into clean, scalable, well-documented SFMC builds, this role offers a platform to shape how our agency delivers CRM for B2B and B2C clients.

Architect Marketing Cloud Data Models: Design and maintain data extensions, relational data models, sendable and non-sendable structures, and Contact Builder attribute groups that support segmentation and personalization at scale.
Build and Optimize Journeys: Develop multi-step, multi-channel journeys in Journey Builder (email, SMS, push, advertising audiences), using decision splits, engagement splits, wait logic, and goals to drive measurable outcomes.
Automate Data and Campaign Operations: Build Automation Studio workflows for data imports, SQL query activities, filters, file transfers, and scheduled sends; monitor automations and resolve failures quickly.
Develop Personalized Campaigns: Code dynamic, responsive email and landing page templates with HTML, CSS, AMPscript, and SSJS; build reusable Content Builder templates, content blocks, and modular design systems.
Integrate Platforms and Data: Configure and support integrations using SFMC REST and SOAP APIs, Marketing Cloud Connect (Sales/Service Cloud), and third-party systems such as CDPs, e-commerce platforms, and analytics tools.
Ensure Quality and Governance: Own QA, testing, and deployment standards for journeys and campaigns; document builds, naming conventions, and data dictionaries; uphold deliverability, consent, and privacy requirements (CAN-SPAM, GDPR, CCPA).
Lead and Advise: Serve as the SFMC technical SME for client and internal teams, mentor junior developers, scope and estimate builds, and support pitches with solution architecture recommendations.
Measure and Improve: Set up tracking and reporting for journey performance, partner with analytics teams on A/B tests, and iterate builds to lift engagement, conversion, and retention.
