About the role
As an SMS Activations Specialist, you'll act as the project manager for each customer's SMS launch. You'll guide customers through activations, coordinate with vendors and carriers, troubleshoot issues, and ensure compliance with messaging requirements. You'll proactively drive the process forward by setting expectations, following up, and holding stakeholders accountable, all while partnering with internal teams to optimize workflows and provide thought leadership on best practices.

• Hold customers and internal stakeholders accountable for completing required actions in a timely manner, proactively following up to prevent delays.
• Track milestones and communicate activation statuses clearly to internal teams and customers.
• Coordinate with vendors to facilitate new codes, migrations, and port-away requests.
• Troubleshoot activations issues quickly, escalating as needed, and ensure codes are fully live across carriers at launch.
• Conduct post-activation audits and coordinate resolutions with customers and vendors.
• Partner with cross-functional teams to improve workflows, processes, and efficiency for future activations.

What we're looking for
You have:

• 2-3 years of experience (or equivalent) in a customer-facing or project management role within a technical or messaging-focused environment.
• Experience managing projects end-to-end and driving deliverables with multiple stakeholders.
• Strong written and verbal communication skills, with the ability to influence and align cross-functional teams.
• With a proactive, hands-on approach, you take ownership and ensure accuracy in your work.
• Comfort navigating complex technical processes and troubleshooting issues for customers.

Nice to have
You may also bring:

• Knowledge of SMS and MMS processes, including short code activations, alphanumeric sender IDs, toll-free verification, number porting, and industry/carrier guidelines.
• Experience coordinating with external vendors and carriers.
• Excel expertise (e.g., vlookup, sumifs, table formulas) for tracking and reporting activations.
