Why we read it this way (7)
No location is specified anywhere in the posting — CBSA and state are left blank. The role may be remote or at an unstated office; remote=false is set conservatively since no remote claim is made.
The title is not stated in the posting. The scope — org-wide technical strategy, system-of-systems architecture, influencing across multiple teams — clearly supports Principal-level classification, not merely Senior.
The degree requirement has three equivalent paths: (1) Bachelor's + 8 years, (2) Master's + 12 years, (3) Bachelor's + 15 years, or equivalent experience. The minimum hard gate is a Bachelor's degree with 8 years, so the degree requirement is set to Bachelors and the overall years minimum to 8.
Python is listed as one of several acceptable coding languages (C, C++, C#, Java, JavaScript, Python). It is named as the primary skill with the others captured as alternatives, reflecting that the JD requires proficiency in at least one of these languages rather than all of them.
Skills such as 'distributed systems', 'cloud-native architecture', 'microservices', 'retrieval-augmented generation', 'prompt orchestration', 'AI agent frameworks', 'evaluation frameworks', and 'responsible AI' are derived from the requirements section of the posting and are marked as hard gates, even though they describe capabilities rather than specific named products — they are the closest concrete technical descriptors the posting provides.
The alternative occupation code 15-1299 (Computer Occupations, All Other) is noted as a runner-up because the role blends principal-level software architecture with AI/ML platform strategy in a way that doesn't map cleanly to a single standard occupation.
Ignored 2 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): cloud-native architecture, prompt orchestration.
