Applied AI Engineer

Work hands-on with LLMs, retrieval systems, and applied ML to ship production AI features. You’ll collaborate closely with engineering, growth, and product to design systems that move real business metrics; not just model benchmarks.

Growth Lead

Own growth strategy end-to-end, from experimentation and SEO/GEO to AI-driven insights and execution. This is a hands-on leadership role for someone who can think strategically, execute tactically, and partner deeply with product and engineering.
