Experienced J2EE Developer - oDesk

Job Description

Development and maintenance of server-side J2EE code for the EnterpriseWizard product. We may also have an opening for a GUI developer with J2EE experience.



The breakthrough we made at EnterpriseWizard is that the software can be configured to meet the needs of clients that range from Chevron and NEC to tiny startups, writing a line of code. Everything is done through a wizard-based customization interface using a standard browser.

You will join the team responsible for developing enhancements to the core functionality, integrating with other systems and any bug fixing. Please note the developers are responsible for writing test cases for the code and testing it carefully -before- it is passed on to QA. The QA department then try to break it.



Please do not apply for this position unless you are score in the top 10% in EJB/J2EE tests.



Pay Scale:



$2,600 - $3,500 per month, plus bonuses of up to $1,000 per month after 3 months.



Our offices are located in Silicon Valley.
