• Lead onboarding and success planning, driving time-to-value, product adoption, and executive alignment.
• Run ongoing customer engagement: QBRs, risk and value reviews, success metrics tracking, and renewal readiness.
• Translate technical findings (OAuth risk, token misuse, third-party app exposure) into business impact and recommended actions for stakeholders and executives.
• Partner cross-functionally with Product, Engineering, and Sales to unblock customers and influence roadmap and priorities.
• Identify and drive expansion opportunities in partnership with Sales.
• Escalate and manage critical issues with clear communication, structured problem-solving, and customer advocacy.

• 5+ years in Customer Success / TAM / post-sales roles supporting enterprise customers
• Cybersecurity experience required (SaaS security, IAM, App Sec, Sec Ops, and/or GRC)
• Proven ownership of a book of business (~10 enterprise accounts) with strong adoption and retention outcomes
• Strong executive presence and ability to translate technical risk into business impact
• Solid technical foundation, fast learner, comfortable with complex security products
• Strong familiarity with OAuth security and token misuse, plus SaaS-to-SaaS integrations; comfortable with SaaS governance topics (app discovery, identity lifecycle management)
• Experience across cloud and enterprise SaaS environments (AWS, Azure, GCP) and familiarity with SIEMs and broader security tooling ecosystems (integrations + operational workflows)
• Comfortable operating in ambiguity in an early-stage environment; willing to travel as needed

The annual compensation for this role is expected to be in the $190,000-$210,000 range in total cash (base salary + variable/OTE), plus equity, depending on experience and qualifications.
