RESEARCH ENGINEER - ADVANCED AI & SIMULATION SYSTEMS $110k-$130k BASE REMOTE ROLE - U.S. BASED Are you interested in working on some of the most cutting-edge AI systems being built today-systems that can understand real-world environments, predict future scenarios, and even extend their own codebase? THE COMPANY This role sits within a quiet, invitation-only R&D group inside a larger tech organization-an elite team dedicated to pushing the boundaries of government and defense innovation. The work is not consumer-facing and not easily searchable; the group operates more like an advanced research unit than a corporate department. You'd join a small, highly technical team building breakthrough systems in simulation, predictive modeling, and AI-driven reasoning-tools that are tested in live operational environments with real-world impact. The pace is fast, the problems are complex, and the mission is unlike anything in traditional tech. THE ROLE As a Research Engineer, you'll work alongside PhD-level scientists to develop next-generation AI systems that model battlefield dynamics, predict behavior, and simulate future states. This includes building LLM-powered pipelines, extending a Python-based codebase, and helping the system "learn" by rewriting its own logic. Key responsibilities include: • Designing and extending Python systems used for real-time simulation and prediction • Building LLM workflows that reason about system state and generate new code • Developing tools that model real-world behavior and future scenarios • Collaborating with researchers and engineers to implement novel AI concepts • Participating in on-site testing at U.S. bases (approx. 15% travel, typically in multi-week cycles) This role blends hands-on engineering, research experimentation, and field validation of cutting-edge AI capabilities. YOUR SKILLS AND EXPERIENCE The successful candidate will have: • Strong hands-on experience with Python • 2+ years of professional engineering experience (5+ years of total programming preferred) • Solid understanding of AI fundamentals or strong curiosity to learn advanced concepts • Excellent problem-solving and communication skills • U.S. citizenship or green card (due to government contract requirements) Preferred experience: • FastAPI, Docker, LLM APIs, Pydantic, or Hugging Face • Background in simulation, metaprogramming, or ML/AI tooling A PhD in a technical field is preferred but not required. THE BENEFITS • $110k-$130k base salary • Remote role, U.S. based • Approximately 15% domestic travel for field testing and integration events • Opportunity to work directly with a Principal Scientist with 20+ years of AI research experience • Highly impactful work with cutting-edge AI systems used in real-world environments
