He is best known for his work on Star Trek, as well as on the re-imagined Battlestar Galactica television series, for which he won a Peabody Award, and on Outlander, based on the novels of the same name by Diana Gabaldon.

As Moore himself recounted in the book, Star Trek: The Next Generation 365, by the fall of 1986, he was "less than a year into my career as a college dropout... working as a medical records technician (otherwise known as a receptionist) at an animal hospital, all the while telling myself that I was actually a professional writer simply awaiting my inevitable discovery.

He co-wrote several episodes with Brannon Braga, developing a successful working relationship that led to them being offered the chance to write the series television finale, "All Good Things..." (which won the 1995 Hugo Award for Best Dramatic Presentation).

During his time on Deep Space Nine, he continued to write episodes that expanded on Klingon culture such as "The House of Quark", "Sons of Mogh", "Rules of Engagement", "Looking for par'Mach in All the Wrong Places", "Soldiers of the Empire", "You Are Cordially Invited..." and "Once More Unto the Breach".

"), co-wrote the episode that featured Star Trek's first same-sex kiss ("Rejoined") and killed off another popular character, Vedek Bareil Antos ("Life Support").

With the end of Deep Space Nine in 1999, Moore transferred over to the production staff of Star Trek: Voyager at the start of its sixth season, where his writing partner Braga was executive producer.

In a January 2000 interview for Cinescape magazine, Moore cited problems in his working relationship with Braga for his short stay: I have very hurt feelings about Brannon.

I was very disappointed that my long-time friend and writing partner acted in that manner, that crossed lines to the point where I felt like I had to walk away from Star Trek, which was something that meant a lot to me for a very long time, from my childhood right through my entire professional career.

[10] In April 2006, Battlestar Galactica was among the winners of the 65th Annual Peabody Awards;[11] Moore was among the writers and producers cited for "plotlines that are deeply personal and relatable, while never compromising their affinity and passion for science fiction.

Starting in August 2006, the Writers Guild ordered production to cease on the Battlestar Galactica: The Resistance series of webisodes which had been produced as a link between the show's second and third seasons.

When the Writers Guild began their strike, Moore felt it was inappropriate to continue to communicate to fans using the "official" blog he maintained on the Scifi Channel website.

As a result, he chose to start a personal website and blog, rondmoore.com, so that he could continue to freely comment on the situation without violating the terms of his membership in the Writers Guild.

[citation needed] With the success of Battlestar Galactica, the Sci Fi Channel announced in April 2006 that Moore and Eick would be producing a spin-off called Caprica with 24 scriptwriter Remi Aubuchon and NBC Universal Television Studio.

In April 2009, Moore, along with several other Battlestar Galactica alumni, made a cameo appearance in the CSI: Crime Scene Investigation episode "A Space Oddity.

"[15] The episode was directed by Michael Nankin (who directed a number of Galactica episodes), written by Bradley Thompson and David Weddle (who both started their TV writing careers on Deep Space Nine, and worked as writer/producers on Galactica) and based on a story by Naren Shankar (who went to school with Moore and started his writing career on Star Trek: The Next Generation).

Several of his Battlestar Galactica colleagues including Grace Park and Rekha Sharma appear in non-speaking cameos, while Kate Vernon is a major guest star in the episode.

[20] In March 2010, following the mixed reception of the first half of Caprica's first season, SyFy channel approached Moore to produce another Battlestar Galactica spin-off.

The second was purchased by NBC and called The McCulloch, an action-adventure series about the crew of a US Coast Guard vessel as they travel the world, to be co-produced by NBC-Universal and Sony.

[24] In 2011, Moore was commissioned by Lucasfilm's Rick McCallum to write scripts for a Star Wars live action TV series, which was being developed for ABC.

[25] Moore developed a series for NBC in 2011 which had been described as "Harry Potter for grown-ups," and it was confirmed on March 3, 2011 that the new show would be called 17th Precinct.

[26] Tricia Helfer, Jamie Bamber,[27] and James Callis[26] had signed up for the new series[28][29] which would have centered around cops at the local 17th Precinct in the fictional city of Excelsior, with Moore writing the pilot.

The potential series would revolve around the town's old-fashioned veteran marshal who solves crimes by drawing on instinct and experience, who butt heads with the young new East Coast crime-solving doctor who relies on emerging forensics and rational inquiry.

[31] Tall Ship Productions announced on Twitter on October 18, 2011, that Justin Lin had signed on to direct a potential pilot episode of Hangtown, in the event that ABC officially orders it.

Helix was described as being "about a team of scientists investigating a possible disease outbreak at an Arctic research facility who find themselves trying to protect the world from annihilation."

[45] In October, he was hired as the new writer, showrunner, and as an executive producer for Sony's God of War adaptation for Amazon Prime Video, replacing Mark Fergus, Hawk Ostby, and Rafe Judkins due to a change in creative direction.
