Senior Software Engineer at UnlikelyAI - Series A neurosymbolic AI startup
LLMs are powerful but notoriously unreliable in regulated industries. UnlikelyAI is solving this by combining generative AI with proprietary symbolic reasoning to deliver deterministic, explainable outcomes. Founded by the creator of Alexa and backed by Series A funding, they are now building a public platform to open their neurosymbolic stack to the world. If you're a high-caliber Python engineer who wants to solve novel algorithmic challenges at the intersection of classical AI and modern LLMs, this is your chance to join a team of experts from Google, Amazon, and Imperial College during a pivotal scaling phase.
