Customer Success Manager - Cybersecurity Startup Career

Supply chain security and Dev Sec Ops  are among the fastest-growing segments in cybersecurity. Building deep expertise here — with customers like OpenAI and Snowflake on your portfolio — is a significant resume accelerator for future roles in enterprise security SaaS.

The up-to $125,000 base plus bonus is competitive for a mid-level CSM in the security/SaaS space, though top-of-market enterprise CSM roles at comparable-stage companies (Series B–D) typically range from $120,000–$160,000. The equity package (10-year exercise window, secondary offering participation) is notably founder-friendly and above standard — a genuine green flag for startup equity value.

• Technical fluency in containers, Dev Sec Ops , and software supply chain security — all in high demand
• Executive-level stakeholder management (up to CISO level)
• Autonomous process-building in an early-stage CS team — foundational for future CS leadership roles

Strong investor backing (Sequoia, Kleiner Perkins), marquee customer logos, and an explicitly new CS team signal both company momentum and career-defining opportunity to shape the function. Unlimited PTO, 100% health coverage, and 18-week parental leave indicate a mature benefits philosophy despite startup stage.

"Up to $125k" language suggests the ceiling is firm; negotiating room may be limited. The role demands high autonomy on a new team — rewarding for self-starters, but potentially lacking mentorship structure for earlier-career candidates. Entrepreneurial mindset is listed as a requirement, not a preference — expect ambiguity.
