• Support short high-impact Terminal engagements and augment the broader TAM function for enterprise in-person commerce customers. • Run focused technical engagements for assigned Terminal customers — pilots, rollouts, SDK/hardware onboarding, and targeted troubleshooting. • Serve as a technical augment to TAMs and Account teams: provide hands-on integration help, gap assessments, and targeted runbooks during the engagement window. • Guide customers through reader provisioning, pairing, SDK integration patterns (mobile/web), and cloud API usage relevant to the engagement scope. • Diagnose and resolve in-person payment issues that arise during pilots or rollouts (connectivity, pairing, contactless/EMV edge cases, reconciliation signals), escalating appropriately. • Produce concise, customer-facing artifacts (integration checklists, short runbooks, sample snippets) tailored to the engagement outcome. • Work with Support, Operations, and Product to surface recurring issues discovered during short engagements and contribute to improvements in documentation, onboarding flows, and troubleshooting playbooks. • Lead technical calls, demo sessions, and occasional on-site work as needed for short-term deployments. • Hand off longer-term operational or product requests to the owning TAM or Account team, and ensure the customer has a clear next-step plan.
