• Identify patterns across customer environments and feed them back to research and product.
• Maintain a high renewal and expansion rate through genuine technical trust, not just relationship management.

Job description

Help customers get real value from every engagement — from onboarding through remediation.

You are the technical relationship customers rely on after the deal closes: helping them scope engagements correctly, interpret findings, and get fixes shipped. This role sits at the intersection of security expertise and customer empathy.

What you'll do

• Onboard new customers — configuring scope, policy flags, and integrations (Jira, Slack, GitHub, etc).
• Walk customers through findings, remediation guidance, and audit-ready reports.
• Act as the escalation point for critical findings and coordinate customer-side response.
• Identify patterns across customer environments and feed them back to research and product.
• Maintain a high renewal and expansion rate through genuine technical trust, not just relationship management.

What we're looking for

• 3+ years in a customer-facing security role — customer success, professional services, or security consulting.
• Able to read and explain security findings (web, API, cloud) to both engineers and executives.
• Comfortable being the calm, technical voice during a critical-severity escalation.
• Strong project-management instincts — nothing falls through the cracks on your watch.

Nice to have

• Experience with SOC 2 / ISO 27001-adjacent customer environments
• Familiarity with ticketing and alerting integrations (Jira, PagerDuty, Slack)

Competitive salary plus meaningful early equity, full health coverage, and a $2,000/yr learning budget.
