Why we read it this way (5)
The posting lists two qualification tiers: (1) Bachelor's + 6+ years, or (2) Master's + 12 years / Bachelor's + 15 years. The minimum hard gate is a Bachelor's degree with 6+ years, so the overall years minimum is set to 6 and the degree requirement to Bachelors. The higher tiers appear to describe a more senior track rather than a separate, harder gate.
The role title is not given. Responsibilities span hands-on architecture, cross-team technical leadership, product roadmap influence, and live-site operations — a profile consistent with a Staff or Principal engineer. Because the posting names no direct reports or people-management duties, it is classified as an individual-contributor Staff engineer rather than an engineering manager (11-3021), though the ambiguity is noted.
The only concrete technologies named are the coding languages listed in the qualifications (C, C++, C#, Java, JavaScript, Python). All other responsibilities are described in generic terms with no specific tools, frameworks, or platforms named — the skills list is therefore limited to what the posting actually states.
The languages are listed as interchangeable alternatives ('including, but not limited to'), so they are captured as a single skill with alternatives rather than separate entries.
'Distributed systems' is extracted as a required skill because the posting explicitly gates on experience managing large-scale distributed systems with high SLAs as a core responsibility.
