Why we read it this way (5)
The title says 'Junior Software Engineer' and the stated relevant experience range is 2–5 years, which is more consistent with a Mid-level role than a true Junior. Seniority is assessed as Mid accordingly.
A Bachelor's degree is listed as 'preferred'; the posting explicitly states Comcast will consider equivalent coursework or professional experience, so no hard degree requirement is set.
C++ is called out as 'preferred' within the preferred-skills section but is also explicitly named in Core Responsibilities ('Develop software and software architecture using C++'), making it a functional requirement of the role.
Go is explicitly called 'a plus' and Ad Tech experience is noted as 'a plus' — Go is captured as preferred; Ad Tech is a domain, not a named technology, so it is omitted.
No office location is specified in the posting. FreeWheel's primary US engineering hub is New York; the CBSA is assigned on that basis and may not be definitive.
