L3 generally represents an entry-level position or the most technical, in-depth support level, depending on the context. In tech (FAANG), L3 is equivalent to a Software Engineer I or a Junior Engineer (0-3 years experience). In IT, it means expert-level support for complex root-cause issues. In networking, L3 is the Network Layer (IP).

Tier 3 Support (L3)
A support agent at this level represents the highest degree of technical expertise in the system and is often a subject expert, system architect, or senior engineer working alongside developers.
L1 handles the basic stuff, L2 deals with deeper technical issues, and L3 involves digging into code and fixing the root cause. In development roles, the terms represent the experience and responsibilities of the developer. L1 is typically a junior, L2 is mid-level, and L3 is senior or lead.
Here is a quick breakdown of the levels based on years of experience: L3 – Very little experience, from fresh out of college to up to 3 years. L4 – 3-10 years experience or completed PhD program. L5 – 5-10+ years experience in a relevant position.
For instance, new graduate engineers start at L3, mid-level at L4, L5 denotes Senior, L6 is Staff, and so on up to L10 (Google Fellow) . Non-engineering roles (product managers, UX designers, data scientists, etc.)
