About The Position

Mission Technologies, a division of Huntington Ingalls Industries, is seeking an experienced Software Engineer to support the Joint Training Synthetic Environment (JTSE) and JLVC Modernization effort under the Joint Staff J7 (JS J 7) contract. This position focuses on designing and implementing Cross Domain Solutions (CDS) that enable secure, interoperable data exchange within joint training and simulation environments.

Requirements

5 years relevant experience with Bachelors in related field; 3 years relevant experience with Masters in related field; 0 years relevant experience with PhD or Juris Doctorate in related field; or High School Diploma or equivalent and 9 years relevant experience.
Must have an active TS/SCI security clearance.
Strong communication skills and ability to collaborate with senior government, military, and technical stakeholders.
Proven ability to work in complex, high stakes environments with a focus on timely, high quality delivery.
Strong critical thinking skills and ability to develop innovative solutions to operational training challenges.
Proficiency in one or more programming languages (Java, C++, Python, or similar).
Experience with simulation protocols such as DIS (Distributed Interactive Simulation) and/or HLA (High Level Architecture).
Understanding of network protocols, data serialization, and structured data formats.
Experience working with secure systems or cross domain technologies.
Familiarity with fixed format or constrained data packet structures.
Ability to work effectively in team environments and communicate complex technical ideas clearly.

Nice To Haves

Hands on experience with Cross Domain Solutions (CDS), including ruleset creation and data guard configuration.
Experience with Joint Live Virtual Constructive (JLVC) environments or other large scale DoD training/simulation systems.
Background in Multi Level Security (MLS) systems, classification markings, and data labeling workflows.
Knowledge of non kinetic effects modeling and simulation.
Experience navigating accreditation processes such as RMF or ICD 503.
Experience with distributed systems, real time simulation, or message oriented middleware.
Understanding of DoD architecture frameworks and joint training system operations.

Responsibilities

Design, develop, and implement CDS rulesets that control data flow between security domains (allow, block, sanitize, transform).
Analyze and map DIS protocol objects and interactions to ensure compatibility with CDS constraints and fixed format data structures.
Support modernization of JLVC HLA FOM components and integrate them within CDS architectures.
Engineer data transformation methods to convert high classification non kinetic effects into releasable low classification formats.
Maintain end to end traceability of training audience actions and system behaviors across classification boundaries.
Coordinate with accrediting authorities to ensure CDS compliance with all security and data handling policies.
Extend and maintain existing DIS based CDS implementations.
Develop technical documentation, including architectures, rulesets, mappings, and data flow specifications.
Participate in system testing, validation, and accreditation activities for CDS-enabled capabilities.
Troubleshoot and resolve issues related to protocol interoperability, data integrity, and cross domain transmission.
Support milestones associated with the Fully Informed Simulation Environment (FISE).
