Hey folks, ever find yourself pondering what it really means to operate as a high-autonomy Senior/Principal Platform Engineer in the C# world? I just read an awesome guide that spells it out.
It dives deep into the technical expectations for an L5+/L6 Senior C# Developer / SaaS Platform Architect, outlining the blend of coding prowess and architectural wisdom needed.
Here are some key takeaways:
- Architectural pragmatism: Knowing when to drop EF Core for raw SQL/Dapper and balancing shared vs. database-per-tenant designs.
- Deep .NET internals: Understanding
SynchronizationContext, memory allocations, and the Generational GC, specifically the Large Object Heap (LOH) for objects >= 85,000 bytes. - Robust multi-tenant security: Implementing defense-in-depth against data leaks using EF Core filters, SQL RLS, and context propagation.
- DI lifetime awareness: Proactively avoiding "Captive Dependencies" (e.g., a
Scopedservice mistakenly injected into aSingleton). - Auth pipeline expertise: Comprehensive understanding of OAuth2/OIDC token flows.
- Leadership through culture: Demonstrating maturity via crisp Architecture Decision Records (ADRs) and constructive code reviews.
It’s a great reminder that senior roles aren't just about writing code, but about architecting resilient, secure systems and leading with clarity.
