Senior Backend Engineer (Growth & Managed Security Service Provider (MSSP))

• You’ll be joining Growth & MSSP - the team that owns the foundational control plane governing what customers can access, what they’ve purchased, and how they’re administered across NodeZero
• If the Pentest Platform is the engine, Enterprise Platform is the operating model that determines who gets to use it and how
• The team’s work spans licensing and entitlements, admin experience, provisioning, notifications, MSP/MSSP capabilities, and auditability
• These aren’t just internal systems - they’re the services that directly shape how customers, administrators, and service providers experience NodeZero every day
• Getting them right means building for correctness, consistency, and trust across a complex multi-tenant commercial model
• This is a senior individual contributor role
• You’ll lead through technical judgment, careful system design, and reliable execution - owning significant pieces of platform infrastructure while contributing to a team that balances feature delivery with long-term platform investment and production health
• 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

• Experience building production applications on cloud platforms (AWS, Azure, GCP) using Docker and Kubernetes
• 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 multi-tenant SaaS platforms with strong tenant isolation - particularly around access controls, data scoping, and account hierarchy
• Hands-on experience with RBAC, authorization, authentication, or SSO systems, and the patterns that make them consistent and auditable at scale
• Experience with licensing, subscription, entitlement, usage metering, or billing-adjacent systems - especially where correctness and consistency across services matter
• Experience designing and building audit log or event history systems with compliance or support requirements in mind
• Familiarity with provisioning and feature-access patterns - auto-provisioning, feature flags, and staged rollout for commercial SaaS products
• Experience building admin consoles or customer self-service workflows, including parent-child or multi-org account management
• Experience with notifications infrastructure - transactional and non-transactional communications, delivery reliability, and preference management
• Experience with MSP, MSSP, or multi-tenant partner models - asset allocation, sub-account management, and usage/reporting visibility
• Production reliability experience: observability tooling, on-call ownership, runbook authorship, and incident response for foundational platform services
• Expert proficiency in SQL and experience with relational database architectures (PostgreSQL); comfort with complex data models involving account hierarchies, usage records, and entitlement state
