• Build person‑level intent and intensity scoring systems.
• Orchestrate campaigns across LinkedIn, Meta and Google APIs.
• Generate automated landing pages with dynamic tracking and analytics.
• Develop lead ingestion, attribution and CRM integrations (Marketo, HubSpot, Salesforce).
• Create internal tooling that powers sales and customer success (Audience Audit, activation workflows).

You will help design systems that

• Abstract away platform complexity.
• Enforce guardrails to prevent wasted spend.
• Balance automation with transparency.
• Scale across multiple business managers and ad accounts.
