Senior Python Engineer - AI Systems

The platform leverages Python and large language models (LLMs) to generate complex, high-quality reports at scale. They are currently seeking a Senior Python / AI Engineer to take ownership of production reliability and system performance across their core platform.

Improve system reliability, testing practices, and release quality. Work closely with Product to translate requirements into scalable technical solutions. Implement and maintain observability, logging, and monitoring systems. Contribute to architecture decisions with a focus on performance and scalability.
