The Role

Job Title: Senior Performance Marketing Specialist

Length: Thru end of year, with possibility of extension

Location: Remote, US

Brainrider is looking for a detail-obsessed Senior Performance Marketing Specialist to own the strategy, quality, and performance of our paid acquisition efforts across search, video, social, and emerging digital channels. This is an execution-heavy role for someone who thrives in the weeds — scrutinizing campaign setups, catching what others miss, and holding agency partners to the highest standard of performance and accuracy.

The ideal candidate comes from an agency background where they've managed multi-channel performance campaigns across a diverse client portfolio, giving them the platform expertise and operational rigor to know exactly what "good" looks like — and the conviction to flag when it doesn't. You'll work closely with our agency partner(s) to ensure flawless execution across paid search, programmatic, and non-traditional media channels, making this a role for someone who combines deep SEM expertise with a QA-first mindset and proactive communication style.

What you'll do

Agency Management & Quality Assurance (Primary Focus)

• Serve as the day-to-day point of contact for agency partner(s) managing paid search, video, social, and programmatic campaigns — setting expectations, defining priorities, holding them accountable to SLAs and optimization cadences, and proactively surfacing gaps or underperformance rather than waiting to be asked
• Own rigorous QA of all agency output — campaign builds, keyword lists, bid strategies, audience targeting, ad copy, tracking/tagging, and budget pacing — before anything goes live
• Review creative assets against platform specs and safe zones before launch — you're the person who catches that the logo is getting clipped on mobile, the headline is truncating at 28 characters instead of 30, or the CTA button is overlapping body text in the ad preview. If it's not pixel-perfect, it doesn't go live
• Enforce strict naming conventions across campaigns, ad groups, creatives, and UTMs — you're the reason the account is navigable, reportable, and audit-ready six months from now
• Maintain a "tight ship" operating cadence — campaign taxonomy is clean, naming is consistent, folders are organized, documentation is current, and nothing launches without a final preflight check

Paid Search and Paid Social Strategy & Oversight (Core Expertise)

• Own the paid search strategy across Google Ads (Search, Shopping, Performance Max), Microsoft Ads, and other SEM platforms — defining keyword architecture, match type strategy, bid frameworks, and budget allocation
• Own paid social strategy across Meta, Reddit, X, TikTok, and more. 
• Drive the experimentation roadmap — define what gets tested (ad copy, bidding strategies, audience segmentation, landing pages), hold the agency to rigorous test design, and ensure learnings are documented and actioned
• Manage and optimize significant monthly budgets with a focus on efficiency metrics (CPA, ROAS, LTV/CAC, payback periods) while maintaining aggressive growth targets

Reporting, Communication & Stakeholder Management

• Build and maintain reporting dashboards and performance frameworks that enable fast, informed decision-making
• Deliver proactive status updates, performance insights, and risk flags to cross-functional stakeholders 
• Translate complex campaign data into clear, actionable narratives for leadership, product marketing, and growth partners
