About The Position

At ALSAC you do more than make a living; you make a difference. We like people who are different…because we’re different, too. As one of the world’s most iconic and respected nonprofits, we know what it’s like to stand out. That’s why we’re looking at you. Your background, perspective, and desire to make an impact set you apart. As we work to help St. Jude cure childhood cancer, we're calling on the game-changers, innovators and visionaries to join our family. Not just for the kids of St. Jude, but also for you. Because at ALSAC, we develop and celebrate our employees. So, bring your whole, authentic self and become part of our shared mission: Finding cures. Saving children.® We’re looking for an AI Platform Engineer II to help build the secure, scalable foundations that power enterprise AI at ALSAC. In this role, you’ll design and develop core platform components—ranging from backend services and cloud infrastructure to the LLM systems that support our retrieval‑augmented generation (RAG) capabilities. You’ll work hands‑on with vectorization platforms, embeddings pipelines, APIs, and automation patterns that keep our AI environment reliable, compliant, and operationally ready. As an Engineer II, you’ll independently own end‑to‑end delivery of moderate features and short projects, collaborate with senior engineers and cross‑functional teams, and mentor Engineer I‑level peers. Whether optimizing our LLM gateway architecture, improving observability across the platform, or contributing to scalable infrastructure‑as‑code, you’ll help shape the AI capabilities that drive innovation and directly support the mission of St. Jude.
