Cymulate is the leader in Adversarial Exposure Validation. Our platform lets enterprises test and verifies security controls using real-world attacks, providing clear evidence of their vulnerabilities and assurance that defenses are effective.

This is not a standard CSE role. We are looking for a rare combination: someone who can engage at the CISO level on security risk and program strategy in the morning, and go deep on platform configuration, control validation logic, or API integration in the afternoon. You will own the post-sales technical relationship for a portfolio of enterprise and strategic accounts across the US, ensuring customers build mature, outcome-driven validation programs that reduce risk and expand over time.

There is a clear and active path to team leadership for the right candidate.

WHAT YOU WILL DO:

• Own the post-sales technical relationship for a portfolio of strategic accounts — from onboarding through expansion and renewal
• Lead security validation workshops and program reviews, translating platform findings into prioritized, evidence-based risk reduction roadmaps for security leadership
• Help customers move from point-in-time assessments to continuous control validation — shifting their security posture from assumed to verified
• Act as the primary escalation point for complex technical issues — platform integrations, SIEM/SOAR/EDR connectors, API customizations, and environment-specific configurations
• Partner with Sales and SE to identify expansion signals, co-develop commercial strategies, and support upsell and cross-sell motions
• Produce customer-facing strategic outputs: control effectiveness reviews, exposure validation reports, program maturity assessments, and board-ready risk narratives
• Deliver platform demonstrations and technical enablement sessions at all levels — from SOC analysts to CISOs
• Act as the voice of the customer internally — feeding product, engineering, and GTM teams with structured intelligence from the field
• Mentor and contribute to the growth of the broader CS team; model what great looks like

WHAT YOU WILL HAVE:

• Security validation and risk reduction mindset — you think in terms of control effectiveness, attack surface reality, and measurable risk reduction; you help customers understand not just what is exposed, but what it means and what to do about it
• Deep technical range — comfortable working across network and endpoint security architecture, SIEM/SOAR/EDR integrations, cloud environments (AWS, Azure, GCP), scripting and API usage (Python, REST), and enterprise identity/AD environments
• Strategic client presence — proven experience engaging C-suite and senior security leadership; you are credible, concise, and commercially aware in high-stakes conversations. Being able to confidently answer questions like “What does this report mean to my business? How can I demonstrate value to the board?”
• Customer success instinct — you measure your success by customer outcomes: retention, expansion, advocacy, and program maturity — not ticket closure rate. You will be the customer advocate within the Cymulate family.
• Enterprise-grade communication — written and verbal; you can produce a board-ready risk narrative and a detailed technical integration guide with equal quality
