Why we read it this way (7)
The role is explicitly hybrid (2 days in-office in Boulder, CO) — not fully remote.
'Distributed systems and APIs' is listed as a single requirement under Minimum Qualifications; REST is used as the canonical API design skill name to represent the API design/service patterns requirement.
'Working knowledge of JavaScript' is listed under Minimum Qualifications with softer language than C#/.NET and SQL Server, but its placement in the required section makes it a hard gate.
Cloud-native architectures and AI-assisted development appear only under Preferred Qualifications.
Energy markets / settlements / trading platform experience and enterprise application modernization experience also appear under Preferred Qualifications but name no specific technology or tool, so they are omitted from the skills list per extraction rules.
The salary range ($135,000–$160,000/year) is stated as a Colorado-law-compliant base compensation estimate; actual pay may vary.
Ignored 1 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): AI-assisted development.
