Here are some websites that I’ve found to have good job listings for animators.
CG Studio Map – This is a site that I feel is a very good, if basic, resource. It provides a comprehensive list of studios ranging from animation and visual effects to post production and contact details for the studios. The site is laid out on a world map that allows one to see all of the studios in a particular region at a glance. The best part of the site is that even studios not actively advertising open positions are visible. http://www.cgstudiomap.com/
CG Society Jobs – CG Society is one of the best community sites and their job site is an equally good resource with many different types of jobs listed. One thing that you aren’t likely to find is any freelance jobs, but for professional-looking studio listings it is good. http://jobs.cgsociety.org/
VFX Jobs – This is another good one. It has postings from major studios and smaller ones. It also allows profiles from individual artists and specific projects. http://vfxjobs.com/
Motionographer Jobs – This is my most frequented site. Has several new job postings every day and allows artists to apply directly. Has jobs for any kind of motion graphics, visual effects, and 3D. I subscribe to their Twitter @MoGraphJobs, which makes job searching convenient. http://motionographer.com/jobs/
You Animator – You Animator isn’t a true job site; rather, it focuses on animation reel reviews by industry pros. This really makes it stand out to me and is recommended even if you plan on searching for studios yourself. http://www.youanimator.com/
Creative Heads – Well laid-out and easy to navigate site. I spotted jobs from Blur, Warner Bros, and SCAD, and it does seem to have plenty of good opportunities. Allows applying from within the site. http://www.creativeheads.net/
Gamasutra – It’s primarily a gaming news site, but also has a job board. It isn’t specifically for artists and animators, but it will probably be your best resource if you’re a game designer. http://gamasutra.com/jobs/
Mandy – I’m including this one because oftentimes it seems that other job sites just repost jobs from Mandy. It’s “all roads lead to Mandy.com,” so to speak. If you’re a filmmaker, animator, or mograph artist looking for work, I really recommend watching this site. http://mandy.com/1/filmtvjobs.cfm
Craigslist – Not something you might ordinarily think of, but there is some respectable job listings for animators and vfx artists. If you use Google Alerts, you can use the “site:” prefix with craigslist.org and your search terms. This will send a compilation of Craigslist ads to your inbox. Presto!
Freelancer – A good freelance website that allows you to bid on projects and contests. Has a very active community and solid reputation. One of the nice things about the site is the ‘Public Clarification Board’ that allows freelancers to ask questions about the job posting. http://www.freelancer.com
Elance – Very similar to Freelancer. Allows clients to ask specific questions of freelancers, rather than just a basic proposal. It also allows e-mail and RSS subscriptions http://www.elance.com
Odesk – This is another freelance site. A little smaller, but still has quite a few job postings. After you login, it displays an aggregated view of all your saved searches. Pretty nice. However, it does not have a portfolio feature. It allows a video link on users’ profiles, but nothing more. http://www.odesk.com
Peopleperhour – Peopleperhour is a more recent entry into the online freelance world. In addition to the ability to bid on job postings, the site’s main focus is the Hourly. Hourlies are specific services offered by freelancers on a hourly basis. It also allows freelancers to include specific portfolio items in proposals.
Creative District – A place for filmmakers to post their film projects and hire crew. This isn’t a very active site, but it can be useful. http://www.creativedistrict.com
Nerdeo – At the time of this writing, the site is still in beta, but it promises to connect “…freelancers and top students with directors and producers, anywhere in the world, providing them with an online facility for more efficient remote collaboration.” So it allows creatives to find projects that they want to work on and contact the clients directly. It seems promising, but it does leave some room to be desired currently. http://signup.nerdeo.net
