Independently train, fine-tune, and optimize advanced AI architectures (including transformers) for complex applications. Apply a broad range of AI/ML techniques (supervised, unsupervised, reinforcement, generative) to solve domain-specific challenges. Lead the development and integration of signal processing, computer vision, and planning algorithms to advance autonomous system functionality. Design and execute large-scale simulations and modeling of AI/ML systems, ensuring scalability, performance, and robustness on CPU/GPU platforms. Preparing & executing demonstration plans, technical briefings, and trade studies/case studies for leadership and program stakeholders Education Ability to mentor and “upskill” engineers with limited or developing AI/ML backgrounds. Experience delivering rapid prototypes or research models under tight schedule pressure. Comfort working with incomplete information and shaping requirements through experimentation. Strong communication skills for translating complex AI concepts to non?AI specialists. Bachelor’s degree in computer science, mathematics, applied statistics, various engineering disciplines, or related STEM discipline 6+ years of experience in a related field. Relevant experience can be considered as a substitute for the required educational qualifications. In the absence of a degree, a minimum of 9 years of related experience is required. Higher level relevant degree may substitute for experience.
