Responsibilities
- 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, platform types, and reusable model interfaces.
- 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.
- Establish verification and validation practices, reference scenarios, regression suites, and quantitative measures of model credibility.
- Work with government, Air Force, and DoD stakeholders to translate operational questions into usable capabilities.
- Lead design and code reviews, mentor teammates, and improve architecture, documentation, testing, and release practices.
- Provide department-wide architectural guidance, contribute to the technical roadmap, lead architectural reviews, and mentor mid-level and senior staff.
Requirements
- Five or more years of professional software-development experience building simulation, autonomy, robotics, game-engine, digital-twin, or similarly complex systems.
- Principal-level expectations require 10+ years of experience.
- Strong production experience in modern C++ and proficiency in Python for tooling, orchestration, analysis, or automation.
- Hands-on experience developing or extending simulation frameworks and experience with event-driven, discrete-event, agent-based, constructive, or distributed simulation architectures.
- Experience representing complex real-world entities and interactions as software abstractions, building extension mechanisms, and making substantial changes in large existing codebases.
- Strong understanding of software architecture, data structures, algorithms, APIs, testing, debugging, and performance engineering.
- Experience with model verification, validation, calibration, or regression testing.
- Ability to translate ambiguous operational or technical requirements into executable engineering plans and clearly document model assumptions and limitations.
- 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.
- Preferred qualifications include AFSIM development, behavior trees, finite state machines, PDDL, DoD mission-analysis programs, operational modeling domains, legacy-system modernization, simulation-framework design, HLA, DIS, OneSAF, JSAF, NGTS, STK, and active TS/SCI clearance.
Benefits
- Health care plan with 100% premium coverage, including medical, dental, and vision.
- 401k with 5% matching.
- Paid time off with uncapped vacation, sick time, and public holidays.
- Flexible hybrid or remote work arrangement.
- Relocation assistance for qualifying employees.
- Pay depends on experience, with the company aiming for the upper end of the salary range.
