Chief Marketo Developer

We are building a Chief Marketo Developer role to lead an enterprise Marketo Engage carve-out, migration, and go-live across multiple integrated systems. You will deliver a production-ready Marketo instance integrated with Salesforce (SFDC), custom Heroku middleware, and key third-party marketing tools, ensuring data integrity and deliverability.

Responsibilities

• Deliver a fully provisioned Marketo production instance and lead the manual structural migration of up to 100 historical marketing programs via the Marketo Program Import Wizard
• Validate that local assets, smart campaigns, and tokens move over without breaking campaign architecture
• Perform a pre-migration inventory of images, emails, landing pages, forms, and smart campaigns to determine what to migrate versus retire
• Audit the source database to remove inactive or duplicate records and create a Data Dictionary covering CRM, Marketo-only, and custom fields
• Extract global unsubscribes, blocklists, and hard bounces from the legacy platform and upload them using Trusted List Import to maintain privacy and deliverability compliance
• Run an end-to-end Salesforce sync using custom sync filters to selectively isolate and import legacy records based on the completed database audit
• Route all inbound lead data through the configured Heroku middleware pipeline and partner with developers to implement UUID matching logic that deduplicates dynamically and avoids API race conditions during parallel database writes
• Merge configuration scripts and routing rules into the version control repository
• Integrate and configure Adobe Marketo Measure to calculate MTA models across active marketing channels, align CRM Campaign touchpoint rules to standard attribution models, and support the design of a durable lead scoring model
• Configure Marketo webhooks and custom API LaunchPoint services to ingest and map data elements from Demandbase, Lytics, ZoomInfo, and Salesforce
• Design and execute a phased IP warming plan in the new Marketo instance to build ISP sender reputation and maximize deliverability ahead of full launch
• Execute end-to-end SIT test scripts to prove data integrity across the SFDC sync and Heroku pipeline, and author a Technical Design Document detailing sync filters, field mappings, deduplication rules, and MTA schema

Requirements

• Extensive hands-on experience as a Marketo Developer with 7+ years delivering advanced implementations
• Adobe Marketo Engage certification
• Deep expertise in native Marketo-Salesforce bidirectional sync, custom sync filters, Salesforce profile permissions, and CRM data schemas
• Proven track record managing large-scale Marketo-to-Marketo migrations, including database cleansing, Program Import Wizard usage, and blackout window coordination
• Demonstrated experience deploying Adobe Marketo Measure, including JavaScript deployment, ad platform integration, and configuring custom and standard attribution models
• Strong understanding of REST APIs, custom webhooks, and data synchronization logic, with experience partnering with developers on Heroku or similar middleware pipelines to resolve deduplication and payload issues
• English proficiency at B2+ (Upper-Intermediate+)
