Sesame Software has an opening on its team for an integration developer. Using our Relational Junction integration platform, you will develop migration and integration procedures for our customers.

Skills needed are a solid working knowledge of SQL in either Oracle or SQL Server, and some experience with writing stored procedures or database triggers. Relational Junction enables development of integrations through a database, which means you do NOT have to understand or work with the Salesforce API's. Prior experience with using Salesforce.com is desireable, especially if as an administrator.

We are looking for a self-motivated individual to join our team as a full-time employee. We have a wide range of employee benefits, including flexible work hours, 100% telecommuting, and health insurance. Our headquarters are located in the San Francisco Bay Area, but your residence does not necessarily need to be here.

We are NOT looking to outsource or subcontract to other companies, so please don't ask. We are also not able to provide H1-B sponsorship.

Please do not reply to this posting. Instead, submit your resume confidentially to careers@sesamesoftware.com
