Strong understanding of enterprise cybersecurity sales motions, including technical discovery, proof of concept execution, production evaluations, customer security architecture, objection handling, and executive level technical storytelling. Demonstrated ability to lead complex escalations involving Sales, Product, Engineering, Support, IT, Security, Legal, and executive stakeholders. Practical fluency with AI enabled workflows, LLM based tooling, knowledge retrieval, prompt engineering, agentic systems, governance models, and safe enterprise adoption patterns. Experience building operating models, intake systems, governance frameworks, enablement libraries, automation workflows, or internal tooling for distributed technical teams. Ability to distinguish experiments from production ready capabilities, and to define the controls needed to move from one to the other. Strong judgment around data access, least privilege, customer confidentiality, security review, compliance boundaries, and responsible AI usage. Excellent written communication skills, with the ability to produce crisp executive updates, technical runbooks, decision registers, operating models, and field ready guidance. A bias toward durable systems, clear ownership, measurable outcomes, and scalable enablement. Preferred Qualifications Experience with Proofpoint products, Sales Engineering workflows, presales support operations, or enterprise cybersecurity field organizations. Experience with Data Security, Insider Threat Management, email security, cloud security, identity workflows, AI security, or enterprise collaboration security. Experience with tools such as Salesforce, Jira, Confluence, GitHub, Slack or Teams, Google Workspace, Workday, CyberArk, SailPoint, vector databases, MCP servers, or enterprise AI platforms. Experience creating governance for custom GPTs, internal AI agents, prompt libraries, knowledge pipelines, or connector based workflows. Experience managing global teams or distributed technical stakeholders across AMER, EMEA, and APJ. Success Looks Like Presales escalations have clear intake, routing, ownership, and closure paths. Field teams get faster access to accurate technical guidance, without relying on one person’s memory or informal channels. AI tooling becomes a governed multiplier for Sales Engineering productivity, not a shadow infrastructure risk. Product advocacy becomes structured, evidence based, and tied to customer and revenue impact. Access approvals, demo infrastructure, lab ownership, and technical queues have named owners and backups. New hires and internal transfers onboard through repeatable checklists and clear technical readiness paths. Leadership gets concise, reliable visibility into risk, workload, blockers, and investment needs. Why Proofpoint?
