The Role
We’re looking for a Senior Software Engineer to help us push the boundaries of applied artificial intelligence in real-world, customer-facing products. You’ll work on systems that power intelligent conversations, context-aware automation, and lightning-quick decision-making. Some of this involves voice, some text, and some pure machine learning magic, but all of it must be production-ready, scalable, and delightful to use. This isn’t a research lab role; it’s about shipping robust, high-performance systems that directly power thousands of real-world interactions every day. You’ll have huge ownership, move fast, and see your work have an immediate impact on a rapidly growing customer base. About You
