About the role

Senior individual contributor role focused on the Growth & MSSP team, owning foundational control plane for licensing, entitlements, admin experience, provisioning, MSP/MSSP capabilities, auditability, and multi-tenant platform reliability across NodeZero.

Responsibilities

  • Design and implement backend services that enforce licensing, entitlements, feature access, usage limits, and packaging rules consistently across NodeZero's product, APIs, and partner workflows.
  • Build and evolve provisioning and onboarding workflows - account setup, entitlement propagation, and auto-provisioning that reliably activates customers without manual intervention.
  • Develop admin experience infrastructure: user access controls, account settings, parent-child account relationships, and the RBAC/authorization patterns that make multi-tenant administration safe and auditable.
  • Build MSP/MSSP capabilities - asset allocation, sub-client management, usage visibility, and reporting workflows that let service providers manage multiple customer environments at scale.
  • Implement audit logging and event history systems that capture administrative, entitlement, usage, and account-level actions for support, compliance, and customer trust.
  • Develop the notifications platform: usage warnings, consumption alerts, overage notices, product announcements, and other transactional and non-transactional communications.
  • Operate these services in production - contributing to monitoring, runbooks, incident response, and support workflows for systems customers depend on daily.
  • Contribute production code that sets the standard for design quality, test coverage, observability, and operational rigor.
  • Collaborate with adjacent teams - Pentest Data Platform and the Platform Integration Team - to ensure entitlement, access, and account-hierarchy rules are applied consistently wherever NodeZero data is exposed.

Qualifications

  • Bachelor's Degree in Computer Science, Computer Engineering, or a related field.
  • 7+ years of professional software engineering experience using modern object-oriented or functional languages (Python, Go, TypeScript, Java, Scala, C++, etc.).
  • Experience building production applications on cloud platforms (AWS, Azure, GCP) using Docker and Kubernetes.
