Are you passionate about cybersecurity and driven by building long-term customer partnerships that truly make an impact?

Then this is your opportunity to play a pivotal role in scaling Customer Success at Hadrian and helping our customers stay ahead of emerging threats!

Who are we:

We are Hadrian - an offensive cybersecurity startup. We are reshaping the future of cybersecurity through the power of agentic AI injected with the hacker’s perspective. Founded in August 2021, we've secured funding and the backing of ABN AMRO Ventures and Cherry Ventures, propelling us into a new era. 

Our goal is to provide companies with an autonomous Threat Exposure Management platform. At Hadrian, we view security through a hacker's eyes because, well, hackers understand hackers best. We continuously map the digital footprint of organizations, discover risks, and prioritize remediation for security teams to harden their external attack surfaces. 

Located in Amsterdam's buzzing Leidseplein and by London's famous Paddington Station, our diverse team from 25+ countries is on a mission to shake things up in offensive security. Join us in making waves and securing over 200 businesses, and be at the forefront of automated offensive security.

Your Role:

As a Customer Success Manager at Hadrian, you will serve as the trusted advisor to our customers. You will own the full post-sales lifecycle from onboarding to renewal and expansion, ensuring customers adopt, realize, and maximize the value of our disruptive cybersecurity platform.

In this fast-paced, high-growth startup environment, you will act as the strategic bridge between customers and internal teams (Sales, Product and Engineering). We’re looking for someone whose ability to combine technical depth with strong relationship management will be critical in driving retention, adoption, and long-term customer satisfaction.

If you are a technically strong, customer-obsessed cybersecurity professional who thrives in scaling environments, we would love to hear from you!

• Onboarding & Adoption: Guide new customers through onboarding, ensuring smooth implementation. Conduct training sessions and provide best practices while ensuring customers adopt key features to maximize value.

• Customer Relationship Management: Act as the primary point of contact for customer queries and needs. Build strong relationships with key stakeholders by conducting regular check-ins (QBRs, EBRs) to assess satisfaction and goals.

• Retention & Expansion: Monitor customer health scores and proactively address churn risks. Identify upsell and cross-sell opportunities for additional features or services and collaborate with sales and marketing on renewals and expansion strategies.

• Support & Issue Resolution: Ensure customers get quick resolutions and escalate when needed and provide feedback to product teams for improvements.

• Product Advocacy & Feedback: Gather customer feedback and share insights with product and engineering teams. Advocate for customers in roadmap discussions and ensure customers understand new features and updates.

• Metrics & Reporting: Track customer engagement, satisfaction, and retention metrics. Use this data to drive strategies for reducing churn and increasing adoption.
