GTM Engineer, Post-Sales

About this role

The GTM Engineer, Post-Sales, takes manual post-sale work (onboarding, billing, orders, renewals) and turns it into infrastructure: deleting what doesn't need to happen, automating what remains, and leaving behind a clean, reliable process. Alongside back-end automation work, this role will be customer-facing, with direct customer contact on issues like billing and onboarding.

What You'll Do

• Automate contract-to-billing configuration, translating signed terms into correct billing setup validated before go-live
• Own the onboarding activation tracker, driving each new customer through to live and billing correctly
• Build billing reconciliation automation that flags discrepancies before customers see them, and own customer-facing resolution of disputes through to close
• Build SIM order intake and logistics automation, taking Account Executives off the operational path
• Build the renewal-admin engine: renewal calendar, auto-renewal comms, and Salesforce renewal-field hygiene, partnering with Revenue Operations
• Extend the existing account health and expansion signal system, routing ready-to-action findings to Account Executives and closing the loop on execution
• Own migration completion tracking and customer communication, partnering with Solutions on technical execution
• Evaluate and integrate AI-powered tooling into the post-sale stack, separating what compounds impact from what adds noise

Outcomes you will drive

• Grow selling capacity: automated billing, onboarding, and order workflows free up AE time for new business, measured by time reclaimed and revenue capacity redirected.
• Raise billing accuracy: contract-to-billing automation, pre-go-live QA, and reconciliation systems keep invoices clean from the start, tracked against the monthly error rate.
• Accelerate onboarding: automated activation tracking and config QA get customers live and billing correctly faster, measured by time-to-activation and first-invoice accuracy.
• Build the renewal engine: an automated renewal calendar, comms, and CRM hygiene system that keeps every account renewal-ready, measured by renewal readiness.
• Grow expansion revenue: automated health scoring and signal detection surface opportunities to AEs before they're missed, measured by findings actioned and revenue recovered.
