We are seeking an expert-level Lead Marketo Developer to lead a complex, enterprise-grade Marketo carve-out and implementation. The ideal candidate will be responsible for delivering a fully functional, production-ready Marketo Engage instance seamlessly integrated with Salesforce (SFDC), custom Heroku middleware, and various third-party marketing technologies.

Responsibilities

- Deliver a fully provisioned Marketo production instance and oversee the structural manual migration of up to 100 historical marketing programs using the Marketo Program Import Wizard
- Ensure active local assets, smart campaigns, and tokens migrate without loss of campaign architecture
- Conduct a thorough pre-migration inventory of existing assets, including images, emails, landing pages, forms, and smart campaigns, to identify what should be migrated versus retired
- Audit the source database to purge inactive or redundant records and build a comprehensive Data Dictionary mapping all CRM, Marketo-only, and custom fields
- Extract general unsubscribes, blocklists, and hard bounces from the legacy system and upload them as a Trusted List Import to maintain strict data privacy and deliverability compliance
- Execute an end-to-end data sync with Salesforce utilizing custom sync filters to selectively isolate and import legacy records based on the completed database audit
- Route all incoming lead data through a configured Heroku middleware pipeline and collaborate with developers to implement UUID matching logic to dynamically deduplicate records and prevent 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 help design a robust 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 gradual IP warming schedule within the new Marketo instance to build sender reputation with ISPs and ensure maximum deliverability prior to full launch
- Execute end-to-end SIT test scripts demonstrating full data integrity across the SFDC sync and Heroku pipeline, and author a comprehensive Technical Design Document detailing sync filters, field mappings, deduplication rules, and MTA schema

- Adobe Marketo Engage certification

- Proven track record managing large-scale Marketo-to-Marketo migrations, including database cleansing, Program Import Wizard usage, and blackout window coordination
