Job description

A technology-focused engineering organization is seeking a senior software engineer to design and develop integrated live, virtual, and constructive simulation solutions supporting the experimentation, testing, and training of multi-agent autonomy software.

This role offers the opportunity to work across the full software development lifecycle, including architecture design, modern C++ and Python development, simulation scenario creation, systems integration, testing, debugging, CI/CD, cybersecurity compliance, and customer deployment.

Engineers collaborate with software, systems, modeling, simulation, and autonomy specialists to deliver scalable, high-performance solutions operating within demanding defense environments.

Responsibilities

Software engineers in this role design, develop, and improve live, virtual, and constructive simulation solutions used to evaluate and train Tactical AI and multi-agent autonomy systems while balancing simulation fidelity, scale, time, and cost.

Engineers design and document LVC architectures, build simulation scenarios, develop adapters, translators, and complex interfaces using modern C++ and Python, and integrate internal, customer-owned, and third-party modeling and simulation technologies.

Additional responsibilities include researching new simulation and communication tools, conducting code reviews, debugging integration issues, contributing to CI/CD pipelines, documenting technical solutions, supporting security compliance, and translating customer requirements into robust software architectures.

Senior engineers may provide technical leadership, mentor junior engineers, promote strong coding practices and design patterns, and work with cross-functional teams to ensure LVC integrations meet performance, scalability, interoperability, and security requirements.

Required Skills

• Experience developing software using modern C++
• Experience using Python
• Experience with live, virtual, and constructive simulation
• Knowledge of DIS, HLA, or DSEEP
• Knowledge of DDS, ZeroMQ, Kafka, Redis, or Protobuf
• Experience with defense simulation tools such as AFSIM, NGTS, or flight simulators
• Experience developing within Linux environments
• Experience using Docker
• Master's degree or equivalent experience in computer science, software engineering, modeling and simulation, or a related discipline
• Must be a U.S. Citizen and hold or be eligible to obtain a U.S. Secret security clearance
• Willingness to travel approximately 25%

Preferred Skills

• PhD in a related engineering field
• Seven or more years of software development experience
• Experience with OMS or UCI
• Experience with MBSE or hardware-in-the-loop testing
• Experience with high-performance computing
• Knowledge of flight test readiness or airworthiness processes
• Experience using Git, GitLab, SonarQube, or Artifactory
• Experience with automated testing and CI/CD pipelines
• Experience working within classified defense environments
