The studio is also seeking a character designer with experience in "MOBA, Action RTS, Action RPG, or Related Genres." Finally, Visceral is looking for a character concept artist for "an upcoming PC action title." Alongside the portfolio requirement, it's noted that "highly stylized pieces with exaggerated proportions" are considered a plus. Given the typically larger number of playable characters in a MOBA, and the need to identify them from a distance, such exaggerated proportions are common among MOBA character designs.
Is Visceral developing a full-on MOBA? Given its recent history with Dead Space, it's possible the studio is working on a shooter with MOBA elements, perhaps something akin to Super Monday Night Combat (though probably much darker in design).
A third, much less likely but still tantalizing possibility: a Jack the Ripper MOBA.
