Senior Software Engineer - Defense Simulation

Design and implement an integrated live, virtual, and constructive defense simulation framework

Location: Fort Walton Beach, Florida

Compensation: $140,000 - 180,000 USD / year

About The Role

Senior Software Engineer

As a Senior Software Engineer, you will lead the design, development, and improvement of integrated live, virtual, and constructive simulation solutions for experimentation, testing, and training of multi-agent autonomy software. You will design and document LVC architectures, create simulation scenarios, write interface code, conduct code reviews, and solve integration roadblocks. Collaborating with cross-functional teams, you will translate requirements into technical solutions while mentoring junior engineers. The role also involves continuous innovation, testing, debugging, documentation, and contributing to CI/CD pipelines and security compliance.

At Applied Intuition, you will:

• Support the experimentation, testing, and training of Tactical AI agents through the development of live, virtual, and constructive simulation solutions, balancing fidelity, scale, time, and cost
• Research and learn new modeling, simulation, and communication tools, including internal and customer-owned prototype software under active development
• Work with 3rd party vendors to incorporate proprietary models while respecting intellectual property boundaries
• Mentor junior engineers and provide technical leadership, fostering a culture of learning and using good coding practices, design patterns, and industry standards
• Software Development: Write, modify, test, and debug efficient code (C++ 2017+, Python 3.10+, and other languages as needed) for adapters, translators, and more complex interfaces
• System Architecture: Design robust LVC integrations that meets performance, scalability, and security requirements

We're looking for someone who has:

• Master's degree or equivalent experience in modeling & simulation, computer science, or software engineering
• Experience using simulation interoperability standards such as DIS, HLA, and DSEEP, as well as custom methods and technologies, to build LVC federations
• Knowledge of communication protocols and serialization mechanisms such as DDS, ZeroMQ, Kafka, Redis, and protobuf
• Experience configuring, integrating, extending, and using defense M&S tools such as AFSIM, NGTS, and flight simulators
• 3+ years of hands-on experience developing performant modern C++ (2017+)
• Experience developing in Docker and containerized development environments, working in Linux-based operating systems (e.g., RHEL, Ubuntu), and using development tools such as git, Visual Studio Code, GitLab, SonarQube, and Artifactory or Azure Container registry

Travel Requirements:

• Willing to travel for company business between our offices, as well as to customer sites (~25%)

Security Requirements:

• Must be a U.S. Citizen
• Must hold or be eligible for a U.S. Secret security clearance

Nice to have:

• PhD degree in related engineering field
• 7+ years of experience developing software in multiple programming languages
• Experience working with government interoperability architectures such as OMS/UCI
• Experience working with model-based systems engineering artifacts, hardware-in-the-loop testing environments, and multi-level security environments
• Experience with high performance computing (HPC) environments
• Experience with flight test readiness and airworthiness processes

Compensation at Applied Intuition for eligible roles includes base salary, equity, and benefits. Base salary is a single component of the total compensation package, which may also include equity in the form of options and/or restricted stock units.

• comprehensive health, dental, vision, life and disability insurance coverage
