This is just pure opinion, but to me it is hard to read and unprofessional. It is certainly unique, but it doesn't project seriousness, which is what I want out of a job discovery service. Omitting the vowel just has the ring of a shady knockoff, scammer, or malware site that capitalizes on typos. Maybe I'm just not used to seeing the consonant string in trademarks or company names, but it strikes me as peculiar rather than creative or edgy.
Second thought: this is a company which can't even manage to register "workriot.com". Even if "WrkRiot" is the brand, I would expect them to grab the domain with the more obvious spelling and have it redirect to wrkriot, but it turns out "workriot.com" is registered to a Finnish hosting provider sitting on the domain. So to recap: the domain with the more obvious alternate spelling of the company is (very likely) up for sale but they still haven't managed to acquire it. That does not engender much confidence in their marketing or management.
In general misspellings are considered bad for SEO because search engines suggest correcting their name to something else. I'm not sure whether that applies here but I have seen it for startups that vowel drop weirdly, etc.
