• Provide technical development and support, including templates, custom functionality, scripts, and troubleshooting

• Partner with IT, Security, Sales Ops, and RevOps to ensure integrations are secure, scalable, and reliable

Project management tool architecture (Asana)

• Partner with Project Management to streamline request intake and campaign workflows to improve visibility, prioritization, and accountability

Enablement

• Create documentation, training, and office hours so teams can use systems confidently
• Drive adoption through clear communication of changes, best practices, and new capabilities

AI and automation optimization

• Find opportunities to apply AI and automation across platforms and workflows (campaign QA, content operations, reporting, intake triage, and more)
• Evaluate and implement native AI features in the stack and build custom agents, prompts, and scripts where valuable
• Establish standards and guardrails for safe, effective AI use
• Measure and report the efficiency gains delivered
