Adprime, Lead Generation Campaign Manager

About AdPrime 

Adprime is a rapidly growing health platform and ad exchange offering solutions for reaching healthcare professionals (HCP) and direct-to-consumer (DTC) brands. Our Exchange aggregates premium digital inventory and connects demand-side buyers with high-quality, compliant health media. We're looking for a driven business development professional to grow our demand-side ecosystem by recruiting DSP partners, deepening existing relationships, and shaping our product to better serve buyers.

Our lead generation business is a core revenue driver, requiring disciplined execution, rigorous measurement, and consistent delivery across multiple partners and campaigns. 

Position Summary

AdPrime is seeking a Lead Generation Campaign Manager to report to and support the Director of Lead Generation by managing day-to-day campaign operations across the full lifecycle, RFP intake coordination, offer setup, landing page workflow, launch readiness, pacing, optimization, partner coordination, QA/compliance checks, and performance reporting. 

They will support the Director-led operating cadence by running daily execution and controls, launch readiness, pacing alignment, partner coordination, QA/compliance checks, and reporting, while maintaining playbooks and supporting process improvements and automation where appropriate. They will surface insights, issues, and recommendations so the Director can make timely decisions on pricing, forecasting, partner strategy, and product improvements. 

This role is accountable for execution and operational controls; the Director retains ownership of commercial strategy, pricing approvals, and partner strategy decisions. 

The ideal candidate will own and run the lead gen operation — from RFP response through page build, campaign launch, daily pacing, optimization, client reporting, and media partner management. They will sit at the center of three workflows: 

• RFP Pipeline — Receive RFPs, build and refine proposals with pricing and targeting strategy, track win/loss, manage IOs, analyze pipeline trends. 
• Landing Pages — Build and manage Unbounce campaign pages: duplication, tag implementation, demo approvals, template library, ensuring pages are correct, compliant, and conversion-ready. 
• Campaign Pacing — Monitor campaigns performance daily via LeadsPedia and media partner reports, own pacing decisions, resolve delivery issues directly with partners, produce performance reports. 

The Lead Generation Campaign Manager will make sure campaigns launch on time, run on pace, and deliver on commitments — and they will build the systems that make it repeatable. 

Responsibilities 

• Own the RFP pipeline: log RFPs, build proposals (CPA/CPC/CPM/hybrid pricing), maintain proposal tracking, conduct post-mortem analysis on lost bids. 
• Build and manage Unbounce landing pages — duplication, tag/tracker implementation, URL management, creative swaps, demo submissions. 
• Own the daily pacing sheet: MTD and yesterday's conversions/clicks, spend, margin, delivery flags (speed up / slow down), and resolution. 
• Manage media partner relationships — hold partners accountable to delivery commitments, negotiate optimization strategies. 
• Coordinate campaign launch readiness across client services, media partners, and internal teams — tags, approvals, reporting access. 
• Produce weekly and monthly performance reports: delivery vs. goals, spend efficiency, margin health, audience-level reporting. 
• Build and maintain operational playbooks and drive automation of pacing, reporting, and status tracking workflows. 

Requirements 

• 3–5+ years in digital campaign management, ad operations, or media operations. 
• Proven ability to manage 10+ concurrent campaigns across the full lifecycle. 
• Experience with campaign platforms (LeadsPedia, Google Campaign Manager, or similar). 
• Strong working knowledge of landing page builders (Unbounce, Instapage, Leadpages, or similar). 
• Advanced Excel/Sheets — formulas, pivot tables, dashboards, pacing infrastructure. 
• Deep understanding of CPA, CPC, CPM pricing and how each affects delivery, margin, and revenue. 
• Experience managing media partner and vendor relationships. 
• Strong written and spoken English; ability to deliver updates and structured recommendations and presentations.

Preferred 

• Experience with lead generation in healthcare, pharma, financial services, education, or other regulated/high-consideration verticals. 
• Familiarity with programmatic platforms (Throttle, Beeswax, The Trade Desk). 
• Basic HTML/JavaScript literacy for tag placement and page structure. 
• RFP response and IO management experience in digital media. 

Tools 

• LeadsPedia
• Unbounce
• Adprime DSP
• Throttle
• Beeswax
• Excel/Sheets 

Growth 

• Path to Senior Campaign Manager or Director-level role as the lead gen business scales and expands into new verticals. Direct partnership with the Director of Lead Generation on business strategy and pricing decisions.
