About The Position

As a Programmatic Media Specialist at MediaOne, General Motors’ in-house media agency, you’ll be on the front lines of our programmatic activation—building, trafficking, and optimizing campaigns across display, online video, audio, CTV, and emerging formats for GM brands including Chevrolet, GMC, Buick, Cadillac, OnStar, and corporate initiatives. You’re hands‑on in the DSPs, close to the data, and excited to turn performance signals into smart, tactical decisions every day. You’ll work alongside channel, audience, and analytics specialists to deliver ambitious performance and brand outcomes across the GM portfolio.

Working proficiency in at least one major DSP (DV360, The Trade Desk, Amazon, Yahoo, etc.).
Understanding of auction mechanics (first‑price auctions, floors, bid strategies).
Understanding of deal structures (open exchange, PMPs, preferred deals, PG).
Understanding of core measurement concepts (viewability, IVT/fraud, brand safety, frequency management).
Comfortable using Excel/Sheets and basic visualization tools for performance analysis.
Strong analytical, detail‑oriented approach; comfortable living in dashboards and log‑level data.
Clear, concise communicator who can explain what the numbers mean and what you plan to do next.
Organized and reliable—able to manage multiple line items and priorities without losing control of pacing or QA.
Curious about the evolving programmatic landscape (identity, SPO, clean rooms, AI‑driven optimization) and eager to test responsibly for large‑scale brands like Chevrolet, GMC, Buick, Cadillac, and OnStar.

Optimize bids, budgets, audiences, and inventory to improve CPM, CTR, CPA, ROAS, viewability, VCR, and reach efficiency.
Execute structured A/B tests (creative, audiences, inventory sources, bid strategies) and document learnings.
Pull and QA performance data from DSPs and reporting tools and conduct ‘proof of performance’ campaign reporting.
Build clear, concise reporting views that highlight what’s working, what isn’t, and what you’re changing next.
Feed insights back to MediaOne channel leads, GM brand teams, and analytics partners to inform future briefs and strategies.
Follow and help refine naming conventions, taxonomies, and QA checklists for campaign setup across GM brands.
Partner closely with media planners, audience teams, and analytics to ensure programmatic is tightly integrated into full‑funnel GM plans.
