Staff Simulation Engineer – Modeling & Simulation

• Design and implement mission- and campaign-level simulation capabilities in modern C++ and Python
• Build and extend event-driven, discrete-event, agent-based, and constructive simulation frameworks
• Own core framework functionality, including event scheduling, simulation time, state transitions, platform abstractions, scenario execution, data collection, and deterministic replay
• Develop models for platforms, sensors, weapons, communications, electronic warfare, jamming, command and control, logistics, and environmental effects
• Extend AFSIM and comparable simulation environments through C++ plugins, framework services, SDK integrations, new platform types, and reusable model interfaces
• Translate operational concepts, system specifications, and subject-matter expertise into maintainable software models with explicit assumptions and testable behavior
• Modernize legacy campaign and mission-analysis tools and integrate them into a coherent simulation architecture
• Build scenario-generation, Monte Carlo, sensitivity-analysis, campaign-execution, and evaluation workflows
• Scale simulations across developer workstations, on-premises infrastructure, and cloud compute while preserving reproducibility and model provenance
• Connect constructive simulations with distributed, operational, hardware-in-the-loop, or human-in-the-loop environments where appropriate
• Establish verification and validation practices, reference scenarios, regression suites, and quantitative measures of model credibility
• Work directly with government, Air Force, and broader DoD stakeholders to understand acquisition questions and deliver usable capabilities quickly
• Collaborate with physics, backend, geospatial, AI, and product teams to integrate the simulation kernel into a larger interactive platform
• Lead design and code reviews, mentor teammates, and improve architecture, documentation, testing, and release practices
• At staff level, define and enforce testing standards, provide architectural guidance, own design documents for major projects, scope complex initiatives, audit technical risks, review high-impact work, lead technical grooming and RFCs, and coordinate across pods

Requirements

• Five or more years of professional software-development experience building simulation, autonomy, robotics, game-engine, digital-twin, or similarly complex systems
• Strong production experience in modern C++, with proficiency in Python for tooling, orchestration, analysis, or automation
• Hands-on experience developing or extending a simulation framework
• Experience with event-driven, discrete-event, agent-based, constructive, or distributed simulation architectures
• Demonstrated ability to represent complex real-world entities, interactions, rules, and edge cases as clear software abstractions
• Experience building plugins, SDKs, reusable model interfaces, framework services, platform types, or similar extension mechanisms
• Strong understanding of software architecture, data structures, algorithms, APIs, testing, debugging, and performance engineering
• Experience making substantial changes within a large existing codebase while maintaining ongoing delivery
• Experience with model verification, validation, calibration, or regression testing
• Ability to turn ambiguous operational or technical requirements into executable engineering plans
• Strong written and verbal communication skills, including the ability to document model assumptions, limitations, interfaces, and intended use
• Bachelor's degree or equivalent experience in computer science, engineering, applied mathematics, operations research, physics, or a related discipline
• Active Secret clearance or eligibility to obtain one
• Direct experience developing AFSIM plugins, framework extensions, event infrastructure, or custom platform types is strongly preferred
• Experience with behavior trees, finite state machines, and planning languages such as PDDL is strongly preferred
• Experience supporting Air Force, Space Force, joint, or broader DoD acquisition and mission-analysis programs is strongly preferred
• Experience developing models for sensors, weapons, electronic warfare, jamming, communications, logistics, or command and control is strongly preferred
• Experience translating or modernizing a large legacy modeling or campaign-analysis system into C++ is strongly preferred
• Experience designing a simulation framework, event stack, plugin architecture, or campaign system from the ground up is strongly preferred
• Familiarity with HLA, DIS, OneSAF, JSAF, NGTS, STK, or other constructive and distributed simulation environments is strongly preferred
• Experience spanning both operational and constructive simulation is strongly preferred
• Active TS/SCI clearance is strongly preferred
• Staff level expectation: 7+ years of experience
