The post is from a recruiter, and they chose their words poorly on multiple parts and in a variety of ways.
First of all, "cut code" is slang for "writing code" in the same way that some people refer to "cutting a check" (or "cheque" for the Brits). It is often considered a derisive term for a complex task, such as with this top Google search result. Basically it reduces the work of a software engineer to being comparable to cutting a vegetable. A chef might be similarly insulted if they were told their job was food slicing, or for that matter telling a Certified Public Accountant that their job is cutting checks.
I'll also add that this ad is supposedly by a HR recruiting professional who should know better, and yet referred to technology as "boys toys". Maybe the author didn't intend sexist sentiment, but a professional should know better than to indicate gender for a job that doesn't specifically require it - and if it does require/prefer it on part of the company, that casts the employer in a very bad light indeed.
They intended to say - I HOPE - that the job involves actually writing new code and developing solutions, working with cool cutting edge technologies (I know it says it's heavily a Java position and most of the tech is old Java enterprise stuff: can't blame a salesman for trying to sizzle things up a bit, I suppose, though they really probably shouldn't in this case - if you know Java you know what it's reputation is).
Also, the last section is terribly worded, where strict requirements are mixed in with descriptions of the ideal candidate.
If I was the writers boss, I'd give them some heavy coaching and instruction. If I was the company who hired the recruiter, I'd just fire them.
