Why we read it this way (7)
The role has no explicit location — it is described as remote-first with no US-only restriction stated, so the US-based flag defaults to true and no CBSA is set.
The title is not given in the posting; seniority is inferred from the 7+ years requirement, mentoring responsibilities, and architectural ownership — consistent with a Senior engineer.
The tech stack (Azure OpenAI, React, Node, MongoDB) appears only in the 'Our stack at Mural' narrative section, not in a requirements block, so those tools are marked preferred.
Deeper AI/ML experience (LLM evaluation, embeddings, retrieval systems) and knowledge graph experience are listed in the 'What You'll Bring' section but framed as additional depth beyond the core requirements ('Deeper…', 'Experience with…' following the primary gates), so they are marked preferred.
The posted compensation includes a variable pay component in addition to the stated base salary range of $181,000–$226,000; the variable portion is unquantified.
The alt SOC 15-1299 is noted because the role's heavy focus on agentic AI platform infrastructure could be read as a novel AI/ML engineering specialty, but the primary day-to-day work is clearly backend software development.
Ignored 2 non-technology phrase(s) as skills (responsibilities/concepts, not named tools): API design, agent orchestration.
