About The Position

Single Grain is hiring a full-time, remote Senior Manager, Paid Media (AI-First) to own paid growth for an assigned book of client accounts. This hands-on, client-facing player-coach role runs paid search, paid social, and programmatic campaigns across Google, Meta, LinkedIn, TikTok, and programmatic channels. The role combines direct account work with building AI workflows that reduce manual production across campaign build-outs, reporting, pacing, creative iteration, and quality assurance. Clients rely on this person as a performance strategist who recommends what to test and connects media spend to pipeline and revenue. The Senior Manager diagnoses each client’s paid program, establishes baselines and targets, manages campaigns within approved budgets, and runs fast test cycles. They use platform automation where appropriate and build and supervise AI agents, checking their outputs before they affect client spend. They lead client strategy calls, provide proactive recommendations, report results in business terms, and document repeatable processes in runbooks. The role reports to Eric Siu, CEO, and is explicitly not a people-manager position. The position is remote within the United States or Latin America, with at least four hours of US time-zone overlap and professional English. Compensation is $100,000–$150,000 USD per year, depending on location. Success is measured by establishing client diagnoses, baselines, targets, and account-health QA workflows; running test cycles and AI-assisted creative iteration; connecting reporting to pipeline or revenue; achieving measurable improvement against baselines; and developing workflows that handle more than 70% of paid production over six to twelve months. The hiring process includes an application, seven email questions, evidence review, a live working session, a paid time-boxed practical exercise on two sample accounts, and references.

Demonstrated AI workflow or agent built to remove real paid-production work, including what it changed.
Ability to explain AI workflow inputs, outputs, and controls, and how agent or platform-automation outputs are checked before affecting spend.

Professional English.
At least four hours of US time-zone overlap.
Freelancing, consulting, or operating one’s own agency as the main current work is not a fit.

Run an account-health and QA agent for every account to monitor weekly pacing, flag anomalies such as spend spikes, broken tracking, and disapprovals, and recommend next tests.
