We're looking for a Customer Success Engineer who is obsessed with making our customers’ software secure. You will be the technical bridge between our customers and our security and engineering teams. This isn't a traditional customer success role where you just close tickets.

You'll manage the onboarding lifecycle, answer deep technical questions, and ensure our customers are getting maximum value from Casco.

You'll Actually Do
  • Own the Onboarding Journey:
    Guide new customers from “signed contract” to “fully operational,” ensuring their first and every future pentest experience is seamless.
  • Manage Concurrent Engagements:
    Stay on top of multiple customer requests, deployments, and feedback loops simultaneously, ensuring nothing falls through the cracks.
  • Be the Security Expert:
    Answer complex security questions, explain how our agents interact with their infrastructure, and help them interpret findings.
  • Triage and Troubleshoot:
    Be the first line of defense for technical FAQs, solving problems directly when possible and escalating appropriately.
  • Advocate for the Customer:
    Gather feedback from the field and work directly with our product and engineering teams to shape the future of the platform.
What We're Looking For

  • Security Mindset:
    Understanding of security principles and ability to speak offensive security language.

    Comfortable reading documentation, understanding API integrations, and troubleshooting software issues.
  • Excellent Communication:
    Ability to explain complex security concepts to all levels of stakeholders.
  • Startup Grittiness:
    Willingness to build automation with AI and adapt quickly to scaling demands.
Nice-to-Have
  • Security

    Certifications:

    CompTIA Security+, CEH, GSEC, or similar.
  • Experience with AI/LLMs:
    Automated tactical work with AI for strategic focus.
