Customer Success Manager

Job Description Job Description

You'll be the go-to person for a portfolio of enterprise accounts, making sure every customer feels supported, informed, and set up for success. You'll keep things moving after calls, stay close to how each account is doing, and give the rest of the team a clear view of where things stand. The CSMs who thrive here are the ones who like to get ahead of things and bring a thoughtful, organized energy to everything they do.

Hidden Layer protects the world's most valuable technologies from adversarial AI attacks. We were founded by AI professionals and security specialists with first-hand experience of how insidious adversarial AI attacks can be to detect and defend against. Determined to prove that these attacks were preventable, the team developed a unique, patent-pending, productized solution to support organizations in accelerating their adoption of AI securely.

Our dedication to innovation has been recognized by prestigious awards such as RSA's Innovation Sandbox Winner, CB Insights AI 100, Cyber Tech 100, and SC's Most Promising Early-Stage Start-up.

Customer Communication & Coordination

Manage ongoing communication across your portfolio: regular check-ins, status updates, and account emails. Join customer calls, take notes, keep things on track, and make sure every action item is captured and assigned. Own all follow-up after calls; track who owns what internally and make sure things actually get done. Handle scheduling coordination so the rest of the team doesn't have to.

Internal Operations

Keep Jira tickets current, correctly labeled, and moving. Maintain accurate health notes and scores so the team always has a real view of account status. Proactively keep the VP of Customer Success informed on account health, risks, and anything that needs visibility or escalation.

Cross-Functional Collaboration

Work alongside the Solution Architect team during onboarding. The SA handles technical setup; you own the customer relationship and make sure nothing gets lost in the transition from Sales. Partner with Technical Support Engineering on issues. Triage what comes in, route it to the right TSE, and own customer communication while it's being resolved. Keep Account Directors informed ahead of renewals, flag at-risk accounts early, and surface upsell opportunities for them to run with.

Be the source of truth on day-to-day account context.

Onboarding & Adoption

Help new customers see value quickly. Onboarding doesn't end when the contract is signed. Monitor product adoption and flag low engagement before it becomes a problem. Own customer communication during escalations.

5+ years in Customer Success or Technical Account Management at a B2B SaaS or cybersecurity company. Experience managing enterprise accounts across technical and executive stakeholders. Exceptionally organized, with a track record of keeping follow-ups and action items from slipping. Strong written and verbal communication skills; clear customer emails, productive calls, clean internal handoffs. Proactive, you stay ahead of accounts rather than waiting for customers to come to you.

Familiarity with tools like Jira or Salesforce is a plus. Background in cybersecurity or AI/ML is a plus, but not required.
