Why we read it this way (6)
The title is 'Principal Engineer' but the actual requirements — 8+ years of full-stack experience, team-level mentoring, and component-level ownership — are consistent with a Senior individual contributor, not a true org-wide Principal. Seniority is set to Senior accordingly.
Java Spring, Python, and Rust are listed together as a single requirement ('Java Spring, Python or Rust'); Java Spring is used as the primary name with Python and Rust as alternatives, since the JD presents them as interchangeable options for the language/framework requirement.
Anthropic Claude is explicitly called out by name in the required qualifications section ('Experience using AI to boost personal productivity, especially Anthropic Claude'), making it a hard gate despite the 'especially' qualifier.
Agentic AI / agentic workflows and AWS Certifications appear under the 'Preferred' section and are marked accordingly.
The role is described as hybrid (office + home), not fully remote.
No specific city is stated in the posting, but Tradeweb is headquartered in New York, NY; the CBSA is inferred from that context.
