Amex GBT is a place where colleagues find inspiration in travel as a force for good and – through their work – can make an impact on our industry. We’re here to help our colleagues achieve success and offer an inclusive and collaborative culture where your voice is valued.

Our Enterprise Data team, part of the Data Governance, Quality & Trust organization, is seeking a Lead MDM Developer to join the NOMAD team. NOMAD is GBT’s Master Data Management platform for supplier reference data, built on Ataccama ONE. It currently covers global hotel data and European rail data, consolidated from multiple supplier and distribution sources into a single governed master record. In this role, you will be the senior hands-on engineer for the platform: designing, building, and hardening the ingestion, cleansing, matching, merging, and publication pipelines that downstream consumers rely on. You will work directly with the Product Manager, MDM Analyst, Data Quality SME, and business stakeholders, and you will help raise the engineering standard of the team as it grows.

What You’ll Do

• Design, develop, and customize the MDM solution on Ataccama ONE, including the solution architecture, MDM data model, and integration patterns, and perform testing and debugging.
• Build and configure data sources and data consumers on the platform, including file-based (MFT) and API-based integrations.
• Develop and tune ingestion, cleansing, standardization, and match/merge logic across multiple source systems, and improve match accuracy and duplicate rates using measurable results.
• Own the publication layer: design and maintain the data deliveries that downstream consumers depend on, and manage the impact of changes on those consumers.
• Investigate and resolve data quality defects at root cause, including malformed source data, rematch gaps, and cleansing rule errors, and deliver hotfixes with regression testing.
• Collaborate with business analysts and stakeholders to understand integration requirements and translate them into technical requirements, estimates, and acceptance criteria.
• Create and maintain technical documentation, workflows, and data mappings so platform knowledge is documented and not held by individuals.
• Act as technical lead for the team: conduct design and code reviews, set development and release standards, and mentor junior developers and contractors.
• Partner with the Ataccama vendor and internal platform teams on upgrades, environment management, performance, and deployments across environments.

What We’re Looking For

• Bachelor’s degree in computer science, information technology, or a related field, or equivalent professional experience.
• 5+ years of experience in MDM, RDM, or a related data management field.
• 2+ years of hands-on experience with an industry-leading MDM vendor platform. Ataccama ONE MDM/RDM is strongly preferred.
• At least one large enterprise end-to-end MDM implementation, from design through production support.
• Strong knowledge of data quality, data integration, and data governance modules and best practices.
• Solid understanding of data cleansing, data standardization, matching and merging techniques, and data workflow processes.
• Strong SQL skills. Python scripting is preferred.
• Experience integrating through file-based (MFT/SFTP) and API patterns, and managing multiple source feeds with differing formats and quality.
• Ability to work independently, prioritize multiple tasks in a fast-paced environment, and make sound technical decisions with limited supervision.
• Excellent verbal and written communication skills, including the ability to explain technical trade-offs to business stakeholders.
• Experience with reference or supplier data, location or address data, or fuzzy matching and entity resolution is a plus.
• Experience in travel, transportation, or enterprise technology sectors is preferred. Familiarity with travel industry data (hotel, rail, air) is a plus.

Location and working arrangement: Gurgaon, India. The role reports to the MDM Product Manager, who is based in Poland, so daily working-hours overlap with Central European time is required. Occasional overlap with US time zones may be needed for stakeholder and vendor meetings.
