Salesforce Marketing Cloud Developer

Our client is seeking an experienced Salesforce Marketing Cloud Developer to improve the reliability, accessibility, and user experience of several public-facing forms built in Marketing Cloud CloudPages.

This is a freelance project for someone with strong experience in CloudPages, AMPscript, JavaScript, and Salesforce integrations.

About the Project

The client’s forms currently submit data from Marketing Cloud into Salesforce. They are looking to improve the form experience by implementing robust client-side validation, preventing invalid submissions from reaching Salesforce, improving error handling, and ensuring compliance with WCAG 2.2 accessibility standards.

• Update Salesforce Contact lookup logic to search only designated Contact Record Types.
• Implement client-side email validation before submission.
• Add international phone number validation (including country code handling) for SMS signup forms.
• Validate all required fields before submission.
• Prevent invalid data from reaching Salesforce or triggering API calls.
• Replace technical backend error pages with user-friendly error messaging.
• Implement an error logging mechanism for monitoring failed submissions.
• Build an emergency “stop” mechanism to temporarily disable processing if a critical issue occurs.
• Ensure validation and error handling meet WCAG 2.2 accessibility requirements, including screen reader compatibility and proper ARIA implementation.

Required Skills

Applicants should have demonstrated experience with:

• Salesforce Marketing Cloud
• CloudPages
• AMPscript
• Salesforce CRM integrations
• JavaScript form validation
• HTML/CSS
• API integrations and error handling
• WCAG 2.2 accessibility standards
• Accessible form development using ARIA attributes
• Experience working with Marketing Cloud forms that create or update Salesforce Contacts is highly preferred.

Deliverables

The completed work should ensure that:

• Invalid or incomplete submissions are blocked before reaching Salesforce.
• Required fields are validated with clear inline messaging.
• International phone numbers are properly validated.
• Users remain on the form page if validation fails.
• Submitted values are preserved after validation errors.
• Technical system errors are never exposed to users.
• Accessible validation meets WCAG 2.2 requirements.
• Failed submissions are logged for administrative review.
• An emergency mechanism is available to halt processing if required.

This is an opportunity to work on an existing Salesforce Marketing Cloud implementation for a well-established international organization, delivering improvements that enhance reliability, accessibility, and the overall supporter experience.
