Senior ColdFusion Developer (Platform Transition and Data Migration)
About the Role
We are seeking an experienced Senior ColdFusion Developer to support a critical transitional project. Our existing marketplace platform, developed in ColdFusion and hosted on AWS, is being replaced by a new system built on a completely modern technology stack.
During this transition period, we need a skilled expert to maintain, stabilize, and improve the current platform while also preparing and executing selective data migration to the new solution.
This role is focused on enabling a smooth, secure, and well-structured transformation rather than long-term ColdFusion feature development.
Primary Responsibilities
Phase 1: Establish Proper Development Infrastructure
Your first and highest priority will be to introduce industry-standard engineering practices to the legacy platform:
- Design and implement a reliable CI/CD pipeline with dedicated staging and production environments
- Create fully separated development, testing, and production database environments (currently all environments are connected to the production database)
- Establish safe deployment workflows and modern version control practices
- Document the current system architecture, integrations, and data models
Enable internal teams to work safely and confidently on the platform throughout the transition period
Phase 2: Data Migration Support (Later Stage)
Once proper infrastructure is in place, you will assist with migration-related tasks:
- Develop middleware components to support selective data transfer to the new platform
- Refactor and cleanse existing data to identify high-quality records that meet defined business requirements
- Migrate approved seller profiles, shop information, and product articles
- Ensure strong data integrity, validation, and consistency during migration
- Collaborate closely with both legacy ColdFusion and new-platform development teams
Required Qualifications
- 5+ years of hands-on ColdFusion development experience
- Prior experience working with marketplace, e-commerce, or retail platforms
- Proficiency with AWS cloud infrastructure and services
- Expert-level knowledge of MySQL, including database normalization and data quality assessment
- Proven track record implementing CI/CD pipelines and DevOps practices
- Experience with data migration or ETL projects
- Strong skills in data refactoring, validation, and cleansing
- Ability to work independently and take ownership during a platform sunset project
Nice to Have
- Experience developing middleware for system migrations
- Knowledge of data mapping across different platforms
- Familiarity with data validation and cleansing strategies
- Previous involvement in sunset or transition projects
- Background in documenting legacy systems for knowledge transfer
Project Context
You will be joining at a pivotal moment. The current ColdFusion platform lacks fundamental development infrastructure:
- No CI/CD pipeline
- No proper staging environment
- All environments share the production database
Your initial mission is to build a safe and standardized engineering ecosystem around the existing system so teams can continue operations without risk while the new platform is being developed.
Later, you will help ensure that only valuable, well-structured, and validated business data (sellers, shops, articles) is migrated to the new solution.
