Here is the actual job description:
Customer Experience Specialist

Amazon.com's Usability Team, based in Seattle, WA, aims to improve the industry-leading usability of the company's web sites. To this end, our human-computer interaction (HCI) specialists provide consultative assistance to interaction designers and other members of engineering project teams, and help them to address tough usability challenges.

As a Customer Experience Specialist, you will apply a variety of cost-effective HCI techniques. Depending on the needs of each project, you may, for example, run field studies, collect and organize customer requirements, develop personas, conduct scenario analyses, facilitate information architecture exercises, conduct heuristic evaluations or cognitive walkthroughs, and/or participate in rapid prototyping cycles.

When the team's usability testing workload becomes high, you will help out by scripting, conducting, and analyzing usability studies of existing and proposed designs. You will be responsible for the recruitment and screening of participants for any studies you conduct.

You will contribute to documents describing user interface principles, standards, and learnings.

In your past work, you have contributed to the effectiveness of consumer-facing web sites. Your training and experience in human-computer interaction includes information architecture, experimental design, and observational methods. You have conducted dozens of usability studies over a period of years. Experience with web programming is desirable.

You have a degree or extensive coursework in human-computer interaction, usability engineering, experimental psychology, anthropology, or a related field. You also have six or more years of experience (preferably more) apart from coursework and academic projects.

You have solid written and verbal communication skills and a desire to experiment with new ideas. You are innovative, flexible and self-directed and have strong people skills. You are good at multi-tasking and time management. Our team employs a rapid development, test-and-learn, mode of operation.

If you are an accomplished user experience specialist interested in providing support to interaction designers, please send a cover letter and resume in confidence to jobs@amazon.com and refer to Job #03-013661.

If your real interest is interaction design, not consulting, please instead search our job pages (http://www.amazon.com/exec/obidos/tg/stores/static/-/jobs/department/Seattle-Headquarters/033/103-7854666-8254267)
for positions with the title "Designer". As either a Designer or a Customer Experience Specialist, you would have many opportunities to exercise your information architecture and usability expertise. The difference is that as a Designer, you would often create designs you could call your own. As a Customer Experience Specialist, you would be involved in a much wider variety of projects.
