Preferred Certifications & Experience * Google Professional ML Engineer, AWS Machine Learning Specialty, or NVIDIA Generative AI/LLM Associate. * Military Equivalency: CMF Work Role Certification (Exploitation/Network Analyst) or experience as a 170A/17A. Years of Experience * Total Experience: 12-15+ years in technical roles. * AI/ML Focus: 5+ years specifically in Machine Learning Engineering or Data Science. The "Technical Closer" label implies you aren't just managing the project; you are the person who steps in to fix the code when the senior engineers get stuck. * Domain Expertise: 3-5 years working within the IC/DoD (Intelligence Community/Dept. of Defense) ecosystem, specifically with systems like Maven or TACMS. Educational Background * Master's Degree or PhD in Data Science, Artificial Intelligence, Computer Science, or Mathematics. * The requirement to fine-tune models (Llama 3, Mistral) using PyTorch/TensorFlow in air-gapped enclaves requires a deep understanding of hardware constraints and model weights that usually comes from advanced academic or special. * Experience Substitution: A Bachelor's degree with an additional 5+ years (totaling 15-20) of high-level engineering experience can often substitute for a Master's, especially if backed by the "Military Equivalency" noted in the description. Clearance Requirement * TS/SCI with CI Poly required. If you're looking for comfort, keep scrolling. At Leidos, we outthink, outbuild, and outpace the status quo - because the mission demands it. We're not hiring followers. We're recruiting the ones who disrupt, provoke, and refuse to fail. Step 10 is ancient history. We're already at step 30 - and moving faster than anyone else dares.
