Position Description:FlexGen is at the forefront of the clean energy revolution, enabling the deployment of grid-scale battery storage systems that stabilize and secure our power infrastructure. Our HybridOS™ platform is transforming how energy assets are controlled, optimized, and maintained. Now, we’re building the next generation of intelligence into our platform—and we need your help to lead the charge. As AI Engineering Lead, you’ll drive the architecture, development, and deployment of our applied LLM and data platform capabilities. This is a hands-on technical leadership role that combines deep machine learning expertise with strategic execution. You’ll work directly on production workflows that incorporate transformers, RAG pipelines, and fine-tuned models, while coordinating a small but high-impact engineering team to deliver scalable solutions. You’ll collaborate across product, platform, and engineering teams to embed AI into real-time industrial workflows that power the grid. This role is ideal for someone who thrives in a fast-moving, mission-driven environment and is excited to see their work make an impact at scale.
