• Serve as the final point of escalation for complex, business-critical customer issues spanning multi-layered software and hardware environments.
• Lead root cause investigations for difficult-to-reproduce or cross-domain issues, coordinating with Product, R&D, QA, and Field Engineering.
• Develop or contribute to diagnostic tools, automation frameworks, and technical resources that improve support efficiency and consistency.
• Own and lead post-incident reviews, ensuring technical resolution and clear communication of remediation strategies.
• Partner with key accounts to resolve long-term technical challenges and represent Spirent in executive-level discussions on support and engineering escalations.
• Participate in customer success planning, contributing to architecture reviews, upgrade strategies, and proactive technical health assessments.
• Act as a trusted technical advisor during major escalations and transformation initiatives.
• Lead or contribute to the design and deployment of scalable support workflows, including automated log parsing, triage tooling, and observability pipelines.
• Identify trends in support data to drive systemic product or process improvements.
• Collaborate cross-functionally to evolve support readiness standards for new product releases or service offerings.
• Represent Technical Support in cross-functional initiatives, including product design reviews.
• Collaborate closely with Engineering, Product Management, and Professional Services to ensure the customer voice is embedded throughout the product lifecycle.
• Contribute to Spirent’s technical culture by championing reliability, supportability, and customer-centric design in engineering practices.
• Follow QEHS (Quality, Environment, Health & Safety, and IT Security) policies and procedures at all times.
