What is a senior AFSim?

A Senior AFSim is a professional who specializes in using the Advanced Framework for Simulation, Integration, and Modeling (AFSim), a government-developed software tool used primarily for modeling and simulating military systems and operations. Senior AFSim specialists design, implement, and analyze complex simulation scenarios to support decision-making, research, and training within defense and aerospace sectors. They often lead teams, develop new simulation capabilities, and ensure the accuracy and relevance of simulation results. Their expertise helps organizations assess system performance, operational concepts, and mission effectiveness in a virtual environment.

What are common collaboration dynamics for a senior AFSim specialist working on multidisciplinary modeling and simulation projects?

Senior AFSim specialists frequently collaborate with software engineers, systems engineers, and subject matter experts to develop, test, and validate advanced simulation models. Effective communication is essential, as the role often requires translating technical simulation requirements into actionable tasks and integrating feedback from various stakeholders. You may also mentor junior team members and coordinate with project managers to ensure deliverables align with broader project goals. These collaborative efforts help ensure simulations are both technically robust and operationally relevant.

What is the difference between Senior Afsim vs Afsim?

AspectSenior AfsimAfsim
CertificationsTypically requires advanced certifications or extensive experience in simulation and modelingEntry to mid-level certifications in simulation or related fields
Work EnvironmentLeads complex simulation projects, supervises teams, and collaborates with military and defense agenciesSupports simulation tasks, assists in project execution, and performs technical duties
Employer & Industry UsagePrimarily in defense, military, and aerospace sectorsUsed across defense, research, and training organizations

In summary, Senior Afsim roles involve leadership, advanced expertise, and project management in simulation environments, whereas Afsim positions focus on supporting simulation tasks with less responsibility. The senior role requires more experience and often involves supervising teams and managing complex projects.

What are the key skills and qualifications needed to thrive as a senior AFSim engineer, and why are they important?

To excel as a Senior AFSim Engineer, you generally need strong programming skills (C++/Python), systems modeling expertise, and a relevant engineering or computer science degree. Experience with AFSim simulation tools, familiarity with military modeling standards, and security clearances are often required. Excellent problem-solving, collaboration, and communication skills help you work effectively on multidisciplinary teams and convey complex technical concepts. These competencies are critical for accurately modeling sophisticated systems and ensuring effective simulation solutions in defense and research settings.

Job description

Description
Are you a seasoned software engineer who enjoys building high-performance systems, working close to the hardware, and solving sophisticated problems with modern tools?
Do you want to apply your experience to challenging problems within national defense?
If so, we 're looking for someone like you to join our team at APL!
The Weapon Systems Engineering group at APL is seeking a Senior Software Engineer to prototype, integrate, test, and deploy next-generation software for advanced weapon and missile defense systems, simulations, and test environments. You'll work at the intersection of embedded software, large-scale simulation, and cloud-native deployment, collaborating with a multidisciplinary team of engineers and analysts. Prior defense experience is not required; experience with real-time systems, game engines, high-performance simulations, or systems-of-systems software frameworks is highly relevant.
As a Senior Software Engineer you will...
  • Provide technical expertise for design and implementation of mission-critical software or software architectures across:
    • In-flight / tactical software using a modular open systems architecture (MOSA)
    • Modeling and simulation (including AFSIM and similar frameworks)
    • Systems-of-systems and Live, Virtual and Constructive (LVC) test environments
  • Develop, build and deploy simulations for:
    • Containerized / Kubernetes environments
    • High-Performance Computing (HPC) environments (e.g., SLURM)
  • Contribute to DevSecOps and GitLab-based workflows
  • Provide technical leadership, mentor others, and collaborate across disciplines

Qualifications
You meet our minimum qualifications for the job if you possess...
  • Bachelor's degree in Computer Science, Computer/Electrical Engineering, Physics, Mathematics, or related field
  • 5+ years professional software development experience
  • Strong proficiency in modern C++ (C++11 or later)
  • Direct experience with Python 3 (tooling, scripting, data processing)
  • Linux development experience (compiling, debugging, shell tools, basic system admin for development)
  • Experience with multi-threaded/concurrent software, including:
  • Threads, async/futures, or similar concurrency approaches
  • Inter-process communication (message queues, JSON, sockets, gRPC, etc.) and performance considerations
  • Experience with Git and branch-and-merge workflows (feature branches, merge/pull requests, code review)
  • Are able to obtain an Interim Secret level security clearance by your start date and can ultimately obtain a Top Secret level clearance. If selected, you will be subject to a government security clearance investigation and must meet the requirements for access to classified information. Eligibility requirements include U.S. citizenship.

Special Working Conditions: Occasional travel to sponsor, contractor, or government facilities for meetings and reviews. Occasional support of test events involving extended hours, travel aboard ships and travel to field sites.
You'll stand out if you have one or more of the following:
  • Master's degree or higher in CS, CE/EE, Physics, Math, or related field
  • Embedded C/C++ or in-flight/real-time software experience
  • Experience with AFSIM, EADSIM, or similar simulation frameworks (game engines, robotics simulators, custom modeling)
  • Hands-on experience with Docker and/or Podman
  • Experience deploying/operating services on Kubernetes (e.g., Rancher, OpenShift)
  • Deep experience with CMake and/or Conan
  • Practical experience with GitLab CI/CD (authoring and maintaining pipelines)
