To thrive as a Junior Data Conversion Developer, you need a solid understanding of database concepts, data mapping, and proficiency in programming languages like SQL or Python, often supported by a relevant degree or technical certification. Familiarity with ETL tools (such as Informatica or Talend), data migration frameworks, and source/target system architectures is typically required. Strong problem-solving skills, attention to detail, and effective communication help in identifying data issues and collaborating with cross-functional teams. These skills ensure accurate, efficient data transformation and integration, which are critical for project success and data integrity.

What are some common challenges faced by Junior Data Conversion Developers during migration projects?

Junior Data Conversion Developers often encounter challenges such as handling inconsistent or incomplete legacy data, adapting to different data formats, and ensuring data integrity throughout the migration process. Collaborating closely with senior developers and business analysts is crucial to accurately interpret client requirements and resolve data discrepancies. Additionally, managing time effectively to meet project deadlines while learning new tools and technologies can be demanding, but it also provides significant opportunities for skill development and growth within the field.

What are Junior Data Conversion Developers?

Junior Data Conversion Developers are entry-level professionals who assist in transforming data from one format to another, often as part of system migrations, software upgrades, or data integration projects. They work under the guidance of senior developers and typically use programming languages, scripts, or specialized tools to extract, transform, and load (ETL) data. Their responsibilities often include analyzing source and target data structures, writing conversion routines, testing data integrity, and troubleshooting issues. This role is crucial for organizations that need to move or consolidate data while ensuring accuracy and minimal disruption.

What is the difference between Junior Data Conversion Developer vs Data Migration Specialist?

The Junior Data Conversion Developer primarily focuses on converting data formats and ensuring data integrity during development. In contrast, a Data Migration Specialist handles larger-scale data transfer projects across systems, often involving planning and execution. While both roles require similar technical skills, the Junior Data Conversion Developer is more entry-level and development-focused, whereas the Data Migration Specialist involves broader project management and enterprise-level tasks.

As a Workday Data Conversion Lead in Definian's Workday practice, you will serve as a subject matter expert and lead on end-to-end data migration activities across Workday implementations. This role sits at the intersection of technical execution, client partnership, team leadership, requiring someone who can strategize and lead data conversion workstreams across the breadth of Workday product implementations, such as HCM, Payroll, and Finance.

The ideal candidate has a 3+ years of Workday specific data conversion experience as a lead, holds active Workday Data Conversion and Data Loading certifications, and has a strong track record of delivering financial data migrations with HCM and payroll experience as a strong differentiator.
Definian is seeking an experienced, certified, Workday Data Conversion Lead to join our Workday team and support our next phase of growth.
What You Will Do
Conversion Strategy & Leadership

  • Lead iterative conversion testing cycles (Foundation, Configuration, End to End, Parallel, and Gold/Production loads), managing defect logs and driving issues to resolution between cycles.
  • Support cutover planning by defining data freeze windows, load dependencies, and go-live readiness criteria in coordination with the project manager and client stakeholders.
  • Manage conversion build timelines and collaborate closely with the project management team on tenant management and scheduling across deployment phases.
  • Produce and maintain conversion governance documentation including sign-off packages, issues logs, and lessons learned artifacts.
  • Communicate conversion status, risks, and escalations clearly to project leadership and client stakeholders throughout each project phase.
  • Mentor and guide junior conversion analysts and support team members across concurrent workstreams.
  • Partner with Workday Practice leadership to build and maintain tools, templates, and repeatable processes that ensure data conversion activities are consistent, high quality, and scalable across engagements.
  • Lead the identification of process improvements and propose changes to Definian's conversion methodology based on project experience and evolving Workday capabilities.

Financial Data Conversion (Required)
  • Lead financial data conversion activities including General Ledger trial balances, open AP and AR transactions, supplier and customer master data, Fixed Assets, banking data, and chart of accounts mapping.
  • Build and execute EIB (Enterprise Interface Builder) templates and XSLT transformations load financial data accurately and on schedule.
  • Develop and execute reconciliation scripts and validation reports to confirm accuracy and completeness of converted financial data against source systems.
  • Partner with client finance teams to resolve data quality issues, mapping gaps, and transformation logic findings throughout the conversion lifecycle.

HCM & Payroll Data Conversion (Preferred)
  • Lead or support HCM data conversion activities including worker profiles, job and position data, compensation structures, benefits elections, and organizational hierarchies.
  • Lead or support Payroll data conversion activities including payroll balance loads (YTD/QTD), tax withholding elections, earnings and deductions history.
  • Coordinate with HCM and Payroll functional consultants to validate converted data against expected outputs and downstream system requirements.

What It Takes
  • Minimum 3 years of experience as a Data Conversion Lead on Workday implementation projects.
  • Must have active Workday Data Conversion and/or Data Loading Certifications (current, non-expired, Workday Pro Certifications a potential alternative).
  • Demonstrated experience loading financial data in Workday, including GL balances, open AP/AR, supplier and customer masters, Fixed Assets, and banking data.
  • Proficiency with Workday Customer Central, EIB, XSLT, and Workday-delivered data migration and load tools.
  • Advanced proficiency in Microsoft Excel for data manipulation, reconciliation, and validation.
  • Proficiency in SQL for data extraction and transformation from relational source systems.
  • Ability to manage multiple concurrent conversion workstreams under tight implementation timelines.
  • Excellent communication skills with the ability to translate technical data concepts for finance, HR, and payroll stakeholders.

Preferred Attributes
  • Hands-on experience converting HCM data in Workday, including worker profiles, positions, compensation, benefits, and org structures.
  • Hands-on experience converting Payroll data in Workday, including payroll balance loads, tax elections, earnings/deductions history, and direct deposit setup.
  • Prior consulting experience with a certified Workday implementation partner or system integrator.

  • Company-paid individual health, dental, vision, disability, and life insurance coverage.
  • Four weeks of paid time off plus ten company-paid holidays.

  • An award-winning culture that combines 40 years of stability with the momentum of a bold new chapter.
  • Salary range is $140,000-$200,000
