- Introduce foundation model optimization techniques to improve scalability, cost, latency, and throughput for large-scale production AI systems.
- Contribute to the technical vision and long-term roadmap for foundational AI systems at Capital One.
- Design and optimize multi-model orchestration pipelines that integrate LLMs, vector search, and domain-specific models into unified systems.
- Establish and lead cost-performance governance reviews across AI systems, including GPU utilization, model throughput, and inference cost efficiency.
- Lead team design councils or design review boards to ensure technical consistency and compliance with AI engineering standards.
- Mentor Principal and Manager-level AI engineers to strengthen cross-domain learning and raise organizational technical maturity.
What we’re looking for
- Master’s degree in Computer Science, AI, Electrical Engineering, Computer Engineering, or related fields, plus at least 4 years of experience developing AI and ML algorithms or technologies. (Or Bachelor’s degree plus at least 6 years of experience.)
- At least 6 years of experience programming with Python, Go, Scala, CUDA, or Java.
Helpful experience
- Leading development of AI systems with tradeoff decisions around cost, latency, throughput, and accuracy.
