Hunter Ellis is putting himself in harm's way for a new hosting role.

The former Survivor: Marquesas castaway and History Channel host has been tapped to helm The CW's new In Harm's Way reality series, Daily Variety reported Tuesday.

Ellis -- the third castaway booted from Survivor's Spring 2002 fourth season -- got his History Channel start when he landed a job hosting Tactical To Practical, a series that explored combat innovations that eventually evolved into useful tools for civilian life.

In 2005, Ellis also began hosting History Channel's Man, Moment, Machine, which focused on the historical consequences of the momentary interaction between a particular individual and a specific technology. 

Last year, the 40-year-old former fighter pilot also replaced Josh Bernstein as host of History Channel's Digging for the Truth.

In Harm's Way is currently slated to debut Sunday, September 21 at 7PM ET/PT before moving to the Sundays at 6:30PM ET/PT timeslot beginning November 2.

Each one-hour episode of In Harm's Way will follow people who frequently risk their lives by working at a dangerous job.  Some of the perilous professions featured on In Harm's Way will include war photographers, oil well cappers, Coast Guard divers and minesweepers.

In Harm's Way is being produced by Pilgrim Films and Television.  Pilgrim founder Craig Piligian -- a former Survivor co-executive producer who also currently produces Discovery Channel's similarly job-focused Dirty Jobs, among other reality series -- is executive producing In Harm's Way.
