Senior Machine Learning Engineer, AI/ML Infrastructure & GenAI Platforms at Zendesk

This role is designed for a seasoned ML Engineer with at least 5 years of experience who is ready to move beyond building individual models and into building the infrastructure that powers them. You should have a strong background in productionizing ML systems and a deep interest in the Generative AI ecosystem, specifically LLM orchestration, evaluation frameworks, and proxy services. The position offers a high level of ownership within a major global brand, focusing on "bleeding edge" tech like agentic workflows and multi-LLM vendor integration (OpenAI, Anthropic, Google). While the listing mentions remote options in Poland and Portugal, it also references a hybrid expectation for team collaboration, offering a blend of flexibility and onsite connection. Perks include premium medical insurance, life assurance, and professional development funds. **You might be a good fit if you...** * Have extensive experience with Kubernetes, Docker, and AWS for scaling ML workloads. * Are proficient in Python and comfortable building developer-facing tools and platforms. * Have hands-on experience with LLM benchmarking, vector databases, and cost optimization. * Thrive in an environment where you are responsible for the full lifecycle of a project, from design to production.
