Principal Simulation Engineer – Modeling & Simulation

Jobtailor; Deutschland; Remote; EUR 110.000 - 150.000; Vollzeit

Zusammenfassung

Jobtailor seeks a senior Simulation Software Engineer to advance mission- and campaign-level simulations in modern C++ and Python. You will extend event-driven, discrete-event, agent-based, and constructive frameworks, own scheduling and replay, and model platforms, sensors, and EW systems.

Collaborate with DoD stakeholders, extend AFSIM plugins, and mentor teammates while driving architecture quality and reproducibility across scalable environments.

Qualifikationen

• Five or more years of professional software-development experience building simulation, autonomy, robotics, game-engine, digital-twin, or similarly complex systems.
• Principal level expectation: 10+ years of experience
• 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
• 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 requirements into executable engineering plans
• Strong written and verbal communication skills, including documenting model assumptions, limitations, interfaces, and intended use
• Active Secret clearance or eligibility to obtain one

Aufgaben

• 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 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 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
• 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
• 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
• Set department-wide quality and correctness standards, provide architectural guidance, scope major initiatives, lead architectural reviews, and mentor staff at scale
