- Master's Degree in Computer Science or related
- SaaS architecture experience
- Net authentication and authorization, permissions & role design.
- Net Security & Clean Architecture.
- Solid knowledge of .Net, EF
- Solid concept of relationship databases & db design.
Must Have:
- Core .NET, C#, modern .NET (Core/5+), not just Framework; ASP.NET Core Web API: EF Core at depth:
- Multi-tenancy
- Real experience with multi-tenant SaaS product, not just read about it
- Can articulate tradeoffs across the isolation models: shared schema with tenant discriminator, schema-per-tenant, database-per-tenant. Should have opinions on migration pain and noisy-neighbor risk. Tenant resolution strategies (subdomain, header, claim) and how tenant context flows through the request pipeline
- Enforcement at the data layer, not just at the controller. EF Core global query filters, and understanding of why filters alone are not sufficient (raw SQL paths, background jobs with no HTTP context)
- Per-tenant configuration, feature flags, and connection routing
- Tenant-aware caching. Knows how cache key collisions become data leaks
- Auth and authorization
OAuth 2.0 and OIDC beyond copy-paste: authorization code + PKCE, client credentials, token lifetimes, refresh rotation, why implicit flow is dead - JWT validation internals: signature, issuer, audience, clock skew, key rotation via JWKS
- BFF pattern experience. Cookie-based session at the edge, token exchange behind it
- ASP.NET Core authorization model: policies, requirements, handlers, resource-based auth. Should prefer policies over scattered role checks
- RBAC vs ABAC, and permission modeling that survives a customer asking for custom roles
- Identity provider integration experience (Entra ID, Auth0, Duende IdentityServer, Keycloak)
- Data and SQL Server
- Strong T-SQL
