Sledgehammer Games is developing a new Call of Duty game, a job listing for the developer has confirmed.

The job ad, which is posted on the studio's website, reveals that Sledgehammer is looking for a Senior FX Artist to help "create the most exceptional real-time effects with hyper realism for [its] next Call of Duty game".

The ad also asks that the candidate has "solid professional experience and knowledge of the limitations and performance of current generation hardware (360, PS3)," suggesting that the game may be intended for current-generation consoles.

Sledgehammer Games collaborated with Call of Duty 4 developer Infinity Ward on last year's Call of Duty: Modern Warfare 3.

And it did a good job, too. Martin called Modern Warfare 3 "a resounding success" when he took a look at it last year.

Prior to Modern Warfare 3, Sledgehammer had been developing a third-person Call of Duty spin-off. It's not known whether this "next Call of Duty game" is a return to that project or a brand new first-person shooter.

Last year, Sledgehammer boss Glen Schofield said that he'd like to make "at least one more first-person shooter", adding that he would "definitely, 100% work with Infinity Ward again".

Infinity Ward, though, is currently developing an unannounced title for next-generation platforms.

This year's Call of Duty, Call of Duty: Black Ops II, is in development at Treyarch.
