Technical Support Specialist , UK

Nash is looking for a Technical Support Specialist to join our global, 24/7 Technical Support team. This role sits at the heart of how Nash stabilizes the platform for our enterprise merchants - owning the investigation, resolution, and clean escalation of complex platform and integration issues across our delivery orchestration system. Technical Support is Nash's intake and stabilization layer for everything beyond high-volume delivery inquiries. You'll be the person customers and internal teams rely on when something unusual is happening on the platform: a stuck integration, an unexpected provider behavior, a configuration question that needs real investigation. You'll resolve what you can, escalate what you can't with the context needed to move quickly, and help build the knowledge base that makes the next occurrence faster. This is a role for someone who enjoys the detective work of complex, ambiguous technical problems, communicates clearly under pressure, and takes ownership seriously. LOCATION Remote in UK (required) UK Time (GMT / BST): Thursday - Monday, 9A - 6P TRAINING 4 weeks, Monday - Friday A note on location This is a remote role, but candidates must be located in the UK. This is a hard requirement driven by contractual data access obligations with our enterprise customers, not a preference - we are not able to make exceptions. WHAT YOU'LL OWN Platform and integration investigation. Diagnose configuration questions, known error patterns, API and webhook issues, and account-specific behavior across the Nash platform. Escalation quality. When an issue needs Engineering or Enterprise Operations, you own the handoff — clear reproduction steps, investigation performed, impact assessment, and severity. Escalations from this team are expected to be actionable on arrival. Incident coordination. Serve as the active shift team for P1 incidents — coordinating communication, engaging Engineering immediately, and keeping customers and internal stakeholders informed through resolution. Proactive monitoring. Watch Datadog dashboards, alerts, and logs for anomalies and emerging risks. Surface issues before they become customer-impacting where possible. Knowledge base contribution. Document resolution patterns for novel issues so the next occurrence becomes a known pattern. Your work directly reduces future escalation volume. Overflow support. Act as overflow for Delivery Support during peak windows when issues exceed their scope. WHAT WE'RE LOOKING FOR 5 - 6+ years in Technical Support, Support Engineering, or a related technical role in a SaaS environment Hands-on experience investigating complex platform issues - not just routing tickets, but actually diagnosing what is happening Comfort with APIs, webhooks, and integration troubleshooting in a production environment Experience with monitoring and observability tools (Datadog, New Relic, Grafana, or similar) Clear, calm written communication — especially during incidents or when customers are fr
