Build subscription and entitlement services, including endpoints consumed by SDKs for real-time user access and feature control
Create statistics and KPI dashboards, providing tenants with visibility into usage metrics, active connections, MAU, and platform health
Implement billing and usage visibility, including usage-based billing summaries, invoice history, and per-tenant consumption breakdowns
Own full-stack delivery of features, from API design and backend services (Node.js) to frontend implementation (Next.js / React)
Collaborate closely with platform, SDK, and infrastructure teams to ensure seamless integration and scalability
Drive best practices in system design, performance, security, and developer experience
(Staff level) Provide technical leadership, mentor engineers, and influence architectural decisions across the platform
What We’re Looking For
Strong experience with Node.js and Next.js/React
Proven ability to own full-stack features end-to-end (API design, integration, frontend architecture, state management)
Experience building B2B platforms, developer portals, or admin/tenant dashboards
Solid understanding of authentication and authorization protocols (OIDC, OAuth2)
Experience designing scalable APIs and backend services
Familiarity with data visualization libraries (e.g., Recharts, Chart.js) for dashboards and reporting
Conduct code reviews and ensure high code quality through automated testing
Contribute to engineering best practices (testing, code quality, documentation)
Nice to Have
Experience with multi-tenant architectures and SaaS platforms
Exposure to usage-based billing systems or subscription platforms
Experience working on security-focused products or privacy-centric applications
