Why we read it this way (5)
The title is 'Senior Principal Full Stack Engineer' — 'Senior Principal' is treated as a Principal advertised level, but the actual scope (leading projects end-to-end, influencing multiple teams, 12+ years required) is consistent with a Senior individual contributor rather than a true org-wide Principal authority.
The Preferred Requirements section is labeled 'Preferred' but several items within it are explicitly stated as 'required' (e.g., JBoss/Wildfly/Spring Boot/Tomcat block, ORM frameworks, SQL/NoSQL databases, domain-driven design). Those internally-required items are marked as hard gates; items described as 'highly desired', 'a plus', or 'familiarity with' are marked preferred.
The posting unusually blends full-stack middleware engineering with data science/ML responsibilities (machine learning, deep learning, statistics, neural networks). The alt SOC 15-2051 (Data Scientists) is noted as a runner-up given this ML/data science emphasis, though the primary framing and majority of requirements are software development.
The 12-year minimum applies to middleware development experience; the 9-year minimum applies specifically to multi-tiered distributed systems in a Linux environment. The higher figure (12) is used as the overall years minimum.
Allegiant Air is headquartered in Las Vegas, NV; no explicit city is stated in the posting but the company's known HQ is used for the metro.
