TNT Growth is a performance-driven growth marketing agency focused on helping ambitious organizations scale through strategic marketing, operational excellence, and exceptional client service. We believe great client experiences begin with strong systems, proactive communication, and a relentless commitment to execution.

This is a building role. You won't be inheriting a polished playbook — you'll be the person who creates it. If you want ownership over a function at a growing agency, not just a seat in someone else's system, this is the role.

• Own the full onboarding lifecycle for new clients from signed contract through launch — kickoffs, timelines, documentation, and delivery.
• Manage 10 concurrent onboardings independently with minimal day-to-day oversight.
• Run kickoff meetings, build onboarding project plans, and drive internal teams through onboarding milestones on deadline.
• Own technical onboarding setup: ad platform access provisioning, Leadsie coordination, DNS/CNAME configuration, landing page and tracking setup, and third-party tool access.
• Maintain onboarding documentation, checklists, and SOPs — and improve them continuously.
• Deliver a high-touch, professional onboarding experience that sets the tone for the client relationship.
• Conduct onboarding satisfaction checks at handoff and use feedback to refine the process.

• Serve as first-responder for client work requests, coordination needs, and reactive issues across high-touch and multi-department accounts.
• Own ticket creation, triage, and status tracking — proactively communicate updates before clients have to ask.
• Coordinate cross-department handoffs and escalation management, using judgment on what to resolve directly vs. escalate to a Growth Manager.
• Monitor client-facing deliverables, deadlines, and action items to ensure nothing gets dropped.

• Drive task accountability, deadline enforcement, and project follow-through across the Growth team.
• Maintain and optimize project management systems in ClickUp and Google Suite.
• Lead operational cadences — standups, scorecards, pacing reviews — to keep the team aligned.
• Create and maintain SOPs, process documentation, and internal operational resources.
• Support reporting, tracking, and operational metrics that give leadership visibility into team performance.

• Identify operational inefficiencies and build scalable solutions — this role exists because the current process needs an owner.
• Baseline onboarding-to-launch timelines and drive measurable improvement quarter over quarter.
• Improve onboarding workflows, client communication processes, and internal coordination systems.
• Lead implementation and adoption of new tools and processes across the team.

• 3 years of experience in client success, account management, or project/program management — ideally at a marketing or growth agency.
• Proven experience owning client onboarding or implementation projects end-to-end, not just supporting them.
• Comfortable with technical setup: ad platform access, DNS/CNAME configuration, third-party tool provisioning. You don't need to be an engineer, but you can't be afraid of a DNS record.
• Experience managing 5-10 concurrent projects with competing deadlines.
• Strong command of project management tools — ClickUp preferred, or Asana, Monday.com, Jira, or similar.
• Proficiency using AI tools for workflow optimization and professional output.
• Exceptional written and verbal communication — you'll be the first voice clients hear after signing.
• Self-directed and reliable in a fully remote environment. This role operates with high autonomy.
• Strong cross-functional coordination skills — you'll work across Growth, Creative, Paid Media, and Client Services daily.

Success in this role may be measured through:

• 90% of onboarding milestones completed on schedule.
• Onboarding-to-launch time reduced ~30% within two quarters.
• Client onboarding satisfaction scores at handoff.
• Project completion and on-time delivery rates across the Growth team.
• Reduction in escalations and dropped handoffs.
• Internal stakeholder satisfaction (Growth Managers, department leads).

• Base Salary of $70k-$100k
• Fully remote work environment.
• Flexible PTO policy.
• Comprehensive benefits package.
• High-growth company with meaningful opportunities for advancement.
• Collaborative, supportive team culture.
• Opportunity to directly influence client success and operational excellence.
• Exposure to a variety of industries, clients, and marketing initiatives.
