Software Engineer, Senior

Designs, develops, and evolves high-fidelity simulation environments and real-time software systems. This role bridges the gap between hardware interfaces and complex software architectures to deliver accurate training and testing platforms. Able to guide others in performing assignments. Ability to define and negotiate simulation engineering requirements, cost of labor assessments and establishing a team structure to execute task/project.

ESSENTIAL FUNCTIONS AND RESPONSIBILITIES: The following duties are essential to the successful and satisfactory performance of this job. Other duties may be assigned. Reasonable accommodations may be made to enable individuals with disabilities to perform the essential functions.

* Creates and modifies a real-time executive and control software.
* Develops and maintains data-centric services.
* Migrates legacy systems to Service Oriented Architecture (SOA) using API-driven design principles and then maintains them.
* Develops and maintains distributed simulation environment with protocols such as DIS, HLA or TENA.
* Designs, creates, modifies, and maintains applications, development frameworks, and systems level software.
* Modifies and writes device drivers (or updating middleware) for interfacing with hardware in a distributed software architecture.
* Designs and develops manual and automated tests to ensure software quality contributing to existing Test suite.
* Performs application design from research to testing phase with limited supervision using structure interfaces and applies object-oriented design principles such as polymorphism, encapsulation and hierarchy.
* Provides recommendations for improvements.
* Provides guidance to less senior engineers in the department.
* Evaluates hardware and software to be installed within a complex distributed training system of system. Provides reports and recommendations.

To perform the job successfully, an individual should demonstrate the following competencies:

* Accountability - Shows up to work as scheduled, and follows instructions, policies, and procedures. Meets productivity standards, deadlines, and work schedules. Accepts full responsibility for quality of work, both independent and team projects.

* Adaptability - Quickly modifies behavior to maintain effectiveness when experiencing major changes in work tasks or work environment. Approaches change as opportunities for learning and development.

* Results Oriented - Focuses on results and desired outcomes and how best to achieve them by ensuring that they and others stay focused on the objective and perform in accordance with clear expectations.

* Teamwork - Cooperates and collaborates with all teammates to achieve common goals by sharing information or expertise; working together to solve problems in a positive manner while valuing the contributions of others.

* Bachelor's degree in engineering and five years related experience, preferably in simulation; or equivalent combination of education and experience.
* Experience required in transitioning legacy software to Service-Oriented Architecture (SOA) utilizing API-driven design principles.
* Knowledge and expertise for this level usually results from internal progressive experience. However, selection for this position is based on the demonstrated ability of the person to successfully fulfill the requirements listed.

* 5+ years of related software engineering experience required.
* Experience with DDS or other Publish/Subscribe (Pub-Sub) messaging protocols preferred.
* Experience with the Joint Simulation Environment (JSE), a secure, distributed simulation environment for large-scale virtual test and training, and the Global Reusable Interface Domain (GRID), a high-performance, low-latency message-passing framework for real-time communication between simulation components, preferred.
