Number of Vacancies 1 Desired Start Date 10/17/2022 Proposed End Date 10/02/2023 Job Open Date 09/16/2022 Job Close Date Open Until Filled Yes Special Instructions to Applicant
This is a larger project requiring the development of multiple modules comprising an integrated system. Modules are currently in different states of development (i.e. completed, in progress, not yet started). We have a clear idea of the remaining development we would like to achieve. We will provide general specifications and/or mock-ups before starting development of each new module, but we do not currently have written specifications for the complete project scope. After discussing a new module's specifications and requirements, then development begins. The freelancer will be expected to provide daily or weekly status updates and the project manager (PM) will be available to answer questions to guide the design. The developer will work as a collaborative team with one other full-stack developer on this complex project. Both developers and the PM will work together on the project and meet virtually using a screenshare 1-3 times per week. Prior development has usually utilized sprint planning to define the next 1-2 weeks of development priorities. This is followed by testing new development at frequent intervals during daily or weekly meetings, and the PM providing guidance on minor modifications to improve the user experience. One role of this position will be assisting to upgrade this older system using the latest technology tools to ensure business continuity for critical operations and data management for the next several years. The PM is a subject-matter expert that defines system requirements and provides design guidance but is not an IT professional. The PM also performs testing of new functionality. The PM has experience managing three different full-stack lead developers for this project over the last 7 years. Other non-IT subject-matter experts will be consulted when necessary to define system specifications more clearly for modules they utilize.
Other Supporting Documents - Please include the following as attachments in the optional documents section:
Provide information on your involvement in previous projects and provide links to websites in your portfolio.
Include a description of your full-stack lead developer experience and communication style.
Submit example source code you have worked on before (e.g., side project, open-source contribution).
*Due to the duration of this project, this temporary position may be considered for a rehire after the proposed end date.
This position is open until filled. This employment site is updated on a regular basis. The length of the recruitment and screening process may vary from position to position, depending upon a variety of factors. Should review of your qualifications result in a decision to pursue your candidacy, you will be contacted by phone or email.
