## Description

As a Senior Backend Engineer on the Onboarding & Provisioning team, you'll build the workflows that activate NodeZero customers-from the purchase event through accurate account and asset provisioning to the customer's first pentest. You'll help ensure entitlements are applied correctly at activation and reduce friction and failure across onboarding paths. This work spans reliable service integrations and asynchronous workflows, with close collaboration across licensing, administration, Product, and customer-facing teams. You'll own significant changes through release and production support, improving how customers move from purchase to successful use of the platform., * Design, build, and operate backend services and workflows that provision customer accounts and assets and activate the appropriate product entitlements.

 * Own projects from technical design through testing, release, observability, and production support, including purchase-triggered and partner-related flows where applicable.
 * Build reliable asynchronous workflows with safe retries, idempotency, error handling, and recovery from partial failures.
 * Improve monitoring and troubleshooting for provisioning and activation; investigate failures and address root causes.
 * Partner with licensing, administration, Product, and customer-facing teams to deliver a consistent path from purchase to product activation.
 * Write tests, design documentation, runbooks, and operational guidance; use rollout practices that support safe changes.
 * Contribute to design and code reviews and support teammates through technical problem solving.

What You'll Bring

 * Strong ownership and sound judgment when working on customer activation paths where accuracy and reliability matter.
 * Ability to reason about distributed workflows, failures, and recovery while keeping customer impact in view.
 * Clear communication and collaboration across service boundaries and with Product and partner teams.
 * Attention to detail and commitment to tested, observable, well-documented production systems.
 * Ability to manage concurrent work, surface risks early, and learn from operational feedback.
