Role
Who you are
- Strong ownership and judgment when working on customer-impacting workflows where correctness matters
- Ability to reason through edge cases and communicate implementation risks and tradeoffs clearly
- A quality-minded approach to testing, data integrity, production support, and technical documentation
- Effective collaboration with Product and engineering partners; willingness to share knowledge and support teammates
- Ability to manage concurrent work while keeping stakeholders informed
- Bachelor’s degree in Computer Science, Computer Engineering, or a related field, or equivalent practical experience
- 7+ years of professional software engineering experience building and operating backend software
- Experience with a modern backend language such as Python, Go, Java, or TypeScript
- Experience designing APIs and data models for business-critical services or customer-facing workflows
- Strong SQL and relational database experience, including data integrity and production troubleshooting
- Experience with cloud-hosted services and containerized applications such as Docker; familiarity with Kubernetes or a comparable orchestrator
- Strong foundation in testing, observability, and ownership of production services
Desirable
- Experience with licensing, entitlements, subscriptions, usage metering, billing-adjacent workflows, or feature access controls
- Experience with multi-tenant SaaS, account hierarchies, RBAC, or partner account models
- Experience with Python or Go, PostgreSQL, GraphQL, AWS, and event-driven or distributed systems
- Familiarity with Kafka or other event-streaming systems, workflow tools such as Temporal or Prefect, and production observability platforms
What the job involves
- As a Senior Backend Engineer on the Licensing, Usage & Entitlements team, you’ll build the services that determine what NodeZero customers have purchased, which capabilities are enabled for them, and how usage limits apply
- You’ll own meaningful work across product packaging, entitlements, and usage workflows for direct and partner accounts. Because these systems affect customer access and downstream product behavior, you’ll focus on correctness, clear service contracts, and reliable operation. You’ll collaborate with Product and adjacent engineering teams to resolve edge cases and deliver changes safely to production
- Design, build, and maintain services and APIs that represent customer purchases, product packaging, enabled capabilities, and usage limits
- Own features from technical design through implementation, testing, rollout, and production operation, with attention to data correctness and customer impact
- Build and evolve entitlement and usage workflows that work consistently across direct and MSP/MSPP account models
- Partner with Product and adjacent teams to define interfaces and resolve edge cases in licensing, packaging, and feature access
- Improve tests, observability, design documentation, runbooks, and support playbooks for business-critical services
- Investigate production issues across service boundaries and implement durable fixes
- Review code and design proposals and share context with other engineers
