Job description

**Description**

Leidos Innovations Center is looking for a Software Engineer in formal methods and cyber-physical systems who has experience with integrating and delivering of state-of-the-art automated reasoning technologies that enable production of high-assurance software and software-intensive systems.

This role will contribute to R&D projects in formal methods, proof engineering, theorem proving, formalized mathematics, gaining hands-on experience developing and applying novel capabilities to address emerging, state-of-the-art technical challenges for software, embedded systems, and cyber-physical systems.

**Please note:** Preference will be given to those who are local and able to be on-site in San Diego, CA or Arlington, VA a few days a week for meetings.

**Primary Responsibilities:**

The Formal Methods Software Engineer will serve in the role of an individual contributor on contract R&D programs working at the direction of a principal investigator or task lead, supporting the development, adaptation, and extension of innovative approaches and solutions in automated reasoning applied research as well as supporting the engagement of customers to develop new business opportunities.

Tasks involved in this role include the development of software and test cases as well as the adaptation and extension of formal methods tools such as theorem provers, solvers, model checkers as the means for producing assurance evidence.

The innovative technical solutions will advance the state of the art while addressing long-term problems of importance to national security.

As such, strong candidates will have demonstrated the ability to make strong contributions as part of high-performing teams in the development and integration of software-based solutions for customers such as DARPA and other branches of the Department of Defense.
