Company Overview:

Cornerstone Defense, in partnership with our military, intelligence, and civil government customers, supports U.S. operations worldwide through the use of many different types of intelligence, satellite, and cyber technologies. Cornerstone’s Intelligence Sector provides solutions to the United States Government for information collection, operations, exploitation and dissemination, and research activities. Our Team specializes in software development, cloud architecture, systems and network engineering, systems integration, agile management, as well as targeting operations and intelligence analysis.

The On-Site Senior Software Engineer position requires someone with a keen ability to rapidly solve software challenges with a focus on communicating effectively with the customer, team, and end users on a highly important and exciting program. The ideal candidate must be able to work independently under pressure and effectively identify, recommend, and solve mission related issues when software solutions are needed. The candidate must be able to communicate and work effectively with remote, non-collocated development teams.

The On-Site Senior Software Engineer will ensure the proper operation of the Mult-Int Analysis and Archive System (MAAS – FMV) which includes many dependencies on other systems (e.g., video encoders, network infrastructure, database, etc). The candidate will focus on front end development related to customer software solutions on-site at the direction of the government customer and the MAAS development team. The candidate may support backend development and collaboration efforts in addition to front end development efforts.
In addition to solving ongoing operational problems, novel software solutions will be greatly valued, especially using the latest accepted software technologies. On-site software implementations and prototypes will be evaluated and migrated back into the formal software baseline at the factory.

The ideal candidate will have a general passion for software solutions and will possess an inquisitive mind that can quickly adapt and work effectively with the entire on-site team.
