Responsibilities
• As a Principal Software Engineer on the Enterprise Platform team, you’ll set technical direction for foundational services that power NodeZero’s customer and partner experiences. You’ll help shape how the platform manages licensing and entitlements, account administration, onboarding and provisioning, notifications, and asset workflows for managed service and security providers. • You’ll guide architecture and execution across teams, partnering with Engineering, Product, and business leaders to make complex platform capabilities secure, reliable, and operable at scale. This is a hands-on individual-contributor role with company-wide technical influence; you’ll develop other technical leaders through mentorship and technical guidance, not formal people management. • Set long-term technical direction for Enterprise Platform capabilities, including licensing and entitlements, user access and account administration, onboarding and provisioning, product and usage notifications, and MSP/MSSP client and sub-client workflows. • Guide architecture for multi-tenant services and account models, including parent-child relationships, permissions, product access, usage limits, and asset allocation across customer and partner accounts. • Partner with Engineering, Product, and business leaders to shape technical priorities and investment decisions; make clear tradeoffs across customer value, security, reliability, scale, delivery speed, and maintainability. • Lead high-impact, cross-team technical initiatives from ambiguous problem to durable solution, establishing the design principles and outcomes teams can execute against. • Stay close to implementation through design reviews, code reviews, technical investigation, and hands-on contributions to critical systems where useful. • Improve production reliability and supportability through testing, observability, monitoring and alerting, safe rollout practices, incident learning, and clear runbooks and support documentation. • Help balance product delivery with operational support, on-call health, and long-term platform investment. • Mentor senior engineers and technical leaders, and create reusable technical guidance that raises engineering quality across teams. • Communicate architecture, risks, and decisions clearly to technical and non-technical stakeholders. • Application Note • In any materials you submit, you may redact or remove age-identifying information such as age, date of birth, or dates of school attendance or graduation. You will not be penalized for redacting or removing this information.
