Full description
We are obsessed with the hero's journey at JobNimbus. Every person has a hero's journey—Hermione Granger, James T. Kirk, Frodo Baggins, Anna & Elsa, Nacho Libre, and even YOU! This is our “call to adventure” to come check out JobNimbus. What do you have to lose? You might make a few new friends, learn about a sick new company doing some amazing things, and maybe even land a new job!
Mission:
Build, scale, and maintain JobNimbus’s identity, authentication, authorization, and account management services. Partner closely with engineering, product, and security teams to implement enterprise SSO, fine-grained access control models (RBAC/ABAC), and secure API auth flows that seamlessly support multi-tenant, parent-child account structures.
What You'll Be Doing:
-
Build, maintain, and enhance backend services powering JobNimbus's identity, authentication, and authorization platform.
-
Implement enterprise SSO integrations (SAML 2.0, OIDC) with customer identity providers such as Okta, Microsoft Entra ID, and Google Workspace.
-
Implement fine-grained access control models—including role-based and attribute-based access control (RBAC/ABAC), permissions, and access profiles—for complex multi-tenant and parent-child account hierarchies.
-
Modernize platform-wide authentication features, including MFA implementation, session/token lifecycles, user provisioning (SCIM), and service-to-service auth.
-
Design and build secure, well-documented RESTful APIs and auth workflows for public/partner APIs (OAuth 2.0 flows, scoped tokens, API key management).
-
Write production-ready code in C# and Node.js with a strong focus on security, performance, and maintainability.
-
Build event-driven backend components for identity events, automated user provisioning, and secure audit logging.
-
Collaborate with product managers, security engineers, and peer developers to translate auth and identity requirements into clear technical designs.
-
Drive operational quality across identity services through unit/integration testing, threat modeling, observability, and proactive monitoring.
-
Leverage AI-assisted development tools to speed up execution, automate routine tasks, and increase code quality.
What Makes You the Hero for This Job:
-
5+ years of professional software engineering experience with a heavy focus on backend services and distributed systems.
