Customer Success Engineer

Casco (YC X25)
Seattle, WA Full Time
POSTED ON 4/13/2026
AVAILABLE BEFORE 5/12/2026
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 are a security success engineer, a trusted advisor for all things application security. You'll manage the onboarding lifecycle, answer deep technical questions, and ensure our customers are getting maximum value from Casco.

What You'll Actually Do

  • Own the Onboarding Journey: You will guide new customers from "signed contract" to "fully operational," ensuring their first and every future pentest experience is seamless
  • Manage Concurrent Engagements: You're always staying on top of multiple customer requests, deployments, and feedback loops simultaneously. You ensure nothing falls through the cracks
  • Be the Security Expert: Customers will ask complex security questions. You need to answer them with confidence, explaining how our agents interact with their infrastructure and helping them interpret findings
  • Triage and Troubleshoot: You are the first line of defense for technical FAQs. You'll solve problems directly when you can and know exactly when to escalate to the core engineering team
  • Advocate for the Customer: You'll 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

Must-Haves

  • Security Mindset: You don't just know what "XSS" or "RCE" stands for. You understand the implications. You have a strong foundation in security principles and can speak the language of offensive security engineers
  • Project Management: You thrive in chaos and can organize it. You have a proven track record of managing multiple stakeholders and complex timelines without losing your cool
  • Technical Proficiency: You are comfortable reading documentation, understanding API integrations, and troubleshooting software issues. You might not write the code, but you can definitely read the logs
  • Excellent Communication: You can explain complex security concepts to a CTO, a CISO, and a non-technical stakeholder in the same meeting
  • Startup Grittiness: You're ready to use AI to build automation where none exists and adapt quickly as demand scales

Nice-to-Have

  • Security Certifications: Bonus points for CompTIA Security , CEH, GSEC, or similar
  • Experience with AI/LLMs: You've automated away tactical work with AI, so you can focus on more strategic work
  • Previous CS/Sales Engineering Experience: You've done this before in a B2B SaaS environment
