Responsibilities

• We’re looking for a Growth Marketing Specialist to join a close-knit team that spans performance marketing, brand, content, and inside sales. Strategy here is built collaboratively — you won’t be handed a blank slate and told to figure it out. You’ll execute and support programs where the team collaboratively sets the direction, meaning you get more context, more backup, and less guesswork. You’ll report to our Director of Performance Marketing and work day-to-day with our Brand Strategy Director, Content Strategy and Messaging Manager, and Inside Sales Manager. The work touches many disciplines, which makes it interesting, but you'll always have a teammate to partner with.
• Paid Media
• Supporting campaign execution in Google Ads and LinkedIn Ads based on strategy set with the performance and brand teams
• Building audience segments and assisting with targeting refinements
• Tracking performance and reporting findings back to the team
• ABM and BDR Support
• Building account lists and top-of-funnel audiences for our inside sales team
• Collaborating with the Inside Sales Manager on account-based campaigns for specific verticals
• Running LinkedIn lead gen campaigns with support from the broader marketing team
• SEO

Requirements

• 2 to 4+ years of B2B marketing experience with ownership of both paid media and ABM programs
• 2 years experience with Search Engine Optimization; including keyword scopes, metadata development, schema micro data content briefs, data analysis, competitive SERP analysis, and related performance analytics.
• AI-forward engineering approach — comfortable leveraging automation, AI agents to scale, smart bidding, and AI-powered tools to improve performance and reporting.
• Experience building and analyzing Ahrefs, SEM Rush Screaming Frog, Search Control, Bing Webmaster Tools, and Google Analytics data
• Proven track record managing paid search (Google Ads, Microsoft Ads) and paid social (LinkedIn) with measurable pipeline impact; ABM platform experience (ZoomInfo, 6sense, Demandbase, or AdRoll) strongly preferred
• HubSpot experience; comfort with multi-touch attribution, UTM frameworks, and CRM-synced audience building
• Deep understanding of long B2B sales cycles, complex buying committees, and enterprise deal structures
• Strong analytical skills with the ability to move fluidly between C-suite strategy and in-platform campaign optimization
• Highly collaborative, sales-aligned mindset with strong cross-functional communication skills; experience supporting enterprise or strategic sales teams

Benefits

• Kastle Systems offers a competitive benefits package, which may include medical, dental, and vision coverage, 401(k) with company match, paid time off, and other benefits, depending on the position and location.
