Jobs at Djinni

Remote | Full-time

Blue Collar Marketing is hiring a Technical Media Buyer to take ownership of both performance marketing and the infrastructure behind it.

This is not a role where you just manage campaigns and report CPLs.

The team is looking for someone who can build the systems that make lead generation more predictable, scalable, and profitable:

• CRM-to-platform attribution
• Meta CAPI + Offline Conversions
• GoHighLevel architecture
• lead quality systems
• reporting tied to actual revenue
• scalable onboarding and tracking infrastructure

You’ll be working with a portfolio that is already performing. 95% of the accounts consistently generate leads every week.

That means the role is much less about fixing chaos — and much more about improving quality, scalability, tracking confidence, and long-term performance.

About Blue Collar Marketing

Blue Collar Marketing is a lead generation agency focused on blue-collar and home service businesses across North America.

The company works with clients across:

• excavation
• construction
• landscaping
• home services
• local trades

Today, the agency supports hundreds of businesses across 45 US states and multiple Canadian provinces.

Why This Role Exists

The agency has already proven it can generate leads.

Now they want to:

• improve attribution accuracy
• reduce junk leads
• optimize toward actual revenue, not just CPL
• standardize tracking and onboarding systems
• create more predictable scaling processes across accounts

This role sits directly in the middle of media buying, tracking infrastructure, analytics, and operational systems.

What You’ll Own

Paid Media Performance

• Manage Meta + Google campaigns across ~23 active accounts
• Own the agency’s internal Meta lead generation account ($30k/month budget)
• Scale spend while maintaining lead quality
• Improve lead-to-call and lead-to-sale quality
• Launch and analyze creative tests weekly
• Troubleshoot underperforming accounts and stabilize CPL volatility

Attribution & Tracking Infrastructure

• Build and improve Meta Conversions API setups
• Implement Google Offline Conversion Tracking
• Create CRM-to-platform attribution loops inside GoHighLevel
• Improve tracking accuracy across the agency
• Build systems that allow campaigns to optimize toward real business outcomes

GoHighLevel Systems

• Standardize onboarding infrastructure for new clients
• Build workflows, triggers, qualification systems, and automations
• Improve lead routing and filtering logic
• Reduce junk leads through qualification and tracking improvements

Reporting & Analytics

• Move reporting beyond CPL into actual ROAS and CAC visibility
• Build scalable reporting systems inside GHL + Looker Studio
• Analyze long-term performance trends
• Turn performance data into actionable business insights for the team

Process Building

• Improve onboarding SOPs
• Standardize tracking and optimization processes
• Help create the future media buying infrastructure of the agency
• Contribute to systems that future buyers will operate within

What They’re Looking For

Must-Have Experience

• 3–5+ years of hands-on Meta Ads experience
• Strong Google Ads experience
• Strong lead generation background
• Experience with GoHighLevel
• Experience implementing Meta CAPI
• Experience with Google Offline Conversion Tracking
• GTM + GA4 knowledge
• Experience managing larger budgets ($30k+/month)
• Strong troubleshooting and analytical thinking
• Ability to improve lead quality — not just lower CPLs

Strong Bonus If You Have

• blue-collar / trades marketing experience
• local service business experience
• agency experience
• WordPress / Elementor experience
• Zapier / Make automations
• YouTube or TikTok Ads experience
• direct-response copywriting skills
• AI workflows for creative/testing processes
•  

What Makes This Role Interesting

• You’re not inheriting broken accounts.
• You’ll have real ownership over both media buying and systems.
• The agency already has strong lead flow and active clients.
• You’ll influence how tracking, attribution, onboarding, and optimization are built going forward.
• There’s a clear path toward building and leading the media buying department.
• You’ll work closely with PMs and developers instead of being isolated as “just the ads person.”
• The role combines strategy, technical systems, analytics, and execution.

Compensation & Benefits

• CAD $50,000 base salary
• Retention bonus structure
• Full-time remote
• 2 weeks paid vacation
• Additional week off in summer + Christmas
• Long-term growth path into Director of Media Buying
