Job Overview

Commerce media is one of the fastest-growing segments in advertising, and Citi is bringing its powerful assets to launch a new media offering. With 70MM+ cardmembers, 6.5 billion annual transactions, and visibility across 700+ merchant categories, Citi has the scale, the trust, and the data infrastructure to compete at the highest level.

What sets Citi apart is the depth and breadth of its view. Where retailers see spending only within their own ecosystem, Citi sees actual purchase behavior across the full customer wallet, spanning categories, merchants, and channels. That cross-wallet visibility, combined with Citi's direct relationships with tens of millions of engaged, digitally active customers, creates a compelling foundation for advertisers who want to reach high-intent audiences and measure real outcomes.

We're building Citi Ads, Citi's Commerce Media business, from the ground up, and we're looking for a technically-minded builder who can help bring our AdTech and data ecosystem to life. This is someone who is comfortable working hands-on across platforms, implementing integrations, configuring tracking, and ensuring systems are set up to support campaign execution, measurement, and scale.

If you're early in your career and have been working within AdTech, MarTech, or data environments and are ready to deepen your technical expertise while helping build a platform from the ground up, this is the role.

The Junior Solution Architect will support the design and implementation of Citi Ads’ AdTech and data infrastructure by translating defined architecture into scalable, working technical components. This is a highly hands-on, detail-oriented role focused on execution—ensuring platforms are properly integrated, configured, and optimized to support campaign activation, ad serving, and measurement.

This role is ideal for an early-career technologist with AdTech or MarTech exposure who enjoys working across systems, troubleshooting integrations, and enabling seamless data flow across platforms.

Responsibilities:

• Support implementation of Citi Ads’ end-to-end AdTech and data architecture across platforms

• Configure and maintain tagging, tracking, and pixels to ensure accurate campaign execution and reporting
• Help build and manage data pipelines, ensuring reliable data ingestion and flow across systems
• Troubleshoot technical issues related to integrations, tracking discrepancies, and data inconsistencies
• Assist in QA and validation of platform integrations, tagging, and measurement frameworks
• Document system configurations, integration logic, and data flows for internal use
• Support log file setup, ingestion validation, and technical QA for measurement and attribution workflows
• Maintain inventory structures, placement setup, taxonomies, and tagging configurations across platforms
• Appropriately assess risk when business decisions are made, demonstrating particular consideration for the firm's reputation and safeguarding Citigroup, its clients and assets, by driving compliance with applicable laws, rules and regulations, adhering to Policy, applying sound ethical judgment regarding personal behavior, conduct and business practices, and escalating, managing and reporting control issues with transparency.

Qualifications:

• 2-5 years of experience in media, branding or advertising analytics
• 2–3 years of experience in AdTech, MarTech, data integration, or technical campaign operations roles
• Experience successfully implementing and validating platform integrations across AdTech and data systems
• Experience tagging and tracking frameworks supporting campaign execution and measurement in an accurate and reliable fashion
• Experience documenting integration specifications, data flows, and system configurations
• Experience generating QA validation outputs ensuring data accuracy and system performance
• Experience providing support for ongoing data architecture needs and technical requirements
