Why we read it this way (8)
The posting lists no work location or metro area; the role is fully remote (eClinical won a 2025 Top Workplaces award specifically for Remote Work).
The degree requirement states 'Bachelor's or Master's in Computer Science or equivalent practical experience' — because equivalent experience is explicitly accepted, no formal degree is treated as a hard gate.
The '10+ years in software design and development using the Microsoft technology stack' is framed as 'preferred' in the posting, but it is the only overall experience figure given and sits in the primary Qualifications block; it is captured as the role-level minimum.
LLM integration experience is listed under the 'AI & Platform Experience' sub-section of Qualifications and is treated as a required skill; OpenAI/Azure OpenAI are named as illustrative examples and are captured as alternatives of one another.
Agent-based/workflow-driven AI architectures are explicitly called 'a strong plus' and are therefore not marked required.
Python is listed in the AI & Platform Experience section as 'Python and/or .NET alongside AI/LLM workflows' — captured as preferred since it is secondary to the primary .NET requirement.
The 'Principal' title is taken at face value for advertised seniority; however, the actual scope and requirements (10+ years, senior IC ownership, mentoring) are consistent with a Senior-level role rather than a true org-wide Principal, so seniority is set to Senior.
No compensation figures are provided in the posting.
