Customer Success Engineer
Customer Success
San Francisco, CA
Full-time
About the Role
We're looking for a Customer Success Engineer who is obsessed with making our customers successful and keeping them 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
What We Offer
San Francisco based: Work from our SF office
Competitive Compensation:
Base salary: $160,000
Equity package with high growth potential
Actual Impact: You will directly influence how major companies adopt autonomous security testing
Learning Opportunities: We support your growth with a budget for conferences, books, and security certifications
Smart Colleagues: Work with a team of ex-AWS engineers and security experts who are genuinely excited about what they build
