What this job asks for AI summary
A hands-on principal-level engineering role focused on building and evolving a large-scale, real-time Decision Management Platform. Day-to-day work spans designing distributed systems, writing and prototyping code, evaluating AI/ML tooling, and improving developer workflows through AI-assisted practices. The role also carries broad technical leadership responsibilities — architectural guidance, mentoring engineers, and contributing to org-wide engineering standards — making it best suited to a senior engineer comfortable operating across both deep technical and cross-functional leadership dimensions.

Why we read it this way (8)
The role is explicitly titled 'Principal Software Engineer' and is described as hands-on (design, code, prototype, validate), which keeps it in the IC software developer SOC rather than the management SOC — but it carries significant org-wide technical leadership, architecture review, and mentoring responsibilities that create genuine ambiguity with 11-3021.
The JD lists two pay ranges (Atlanta, GA: $195,000–$323,000; Arlington, VA: $224,000–$371,000). The min/max fields reflect the full span across both locations; the CBSA is set to Atlanta as the first-listed location.
The Requirements section is unusually sparse and qualitative ('extensive experience', 'proven delivery', 'expertise in cloud, AI/data platforms'). No specific technology is hard-gated by name in that section. The Technical Domains section is explicitly framed as areas where candidates need depth in 'one or more' — not all — so those technologies are treated as preferred rather than hard gates.
A Bachelor's degree is listed in Requirements but immediately qualified with 'or equivalent'; degree requirement is therefore treated as None.
No overall years-of-experience figure is stated in the JD.
The posting notes telecommuting 'may be permissible pursuant to company policies' — this is not a firm remote-work offer, so remote is set to false.
Several technical domain skills (event streaming, LLMs, feature engineering, data lakehouse, GitOps, business rules engines, model observability) appear only in the 'Technical Domains' narrative, which explicitly states candidates need expertise in 'one or more' areas — all are treated as preferred.
Ignored 2 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): low-latency data technologies, ML lifecycle engineering.
