Revised Consulting project - Embedded Linux developer

by John Spencer

My client in MA has the following needs for an embedded Linux/C consultant(s). This could be one position if the developer can do the architecture as well. Otherwise they will need an architect as well as a developer. If you are qualified and interested, please give me a call or send me an email. 1. Architect key changes to their thin client which is Linux 2.6 based which is being moved over to a mobile device. The key is architecture. Strong documentation, strong embedded Linux (ideally 2.6). Estimated about 3 weeks to do the architecture. 2. Development role will include constructing the framework, defining the API, implementing lower layer (abstraction) interfaces from sockets to application stacks like SIP/RTP, etc. strong C and Linux. Embedded Linux architect required to perform high level analysis and design work for a project that involves porting an existing thick client to a Linux/Java environment for the mobile industry. Consultant's responsibilities will include: - taking the recommendations from the customer - quickly learning the existing client architecture - identifying and developing the best approach to porting the client - delivering a complete design and porting guide using best practices - remaining available for ad-hoc consultation throughout the stages of the port Successful consultant must have solid experience in embedded Linux and C. Any knowledge of Java ME(J2ME) is a plus, experience in designing clients for such environments, and the proven ability to lead a team in the initial design phases of a project. Estimated about 3 mths to do this piece of the project. The development team exists and is ready to begin the porting effort, but needs strong guidance from an experienced, senior architect. Must be able to start soon.
