Research Engineer
Research Engineers at these organizations work across the full stack—from implementing cutting-edge algorithms and optimizing models for specialized hardware, to building scalable infrastructure that translates research prototypes into production systems. They combine deep machine learning expertise with strong software engineering skills, often bridging gaps between research scientists and infrastructure teams to accelerate progress on frontier AI problems like inference optimization, reinforcement learning for robotics and reasoning, multimodal generation, and agentic systems. These roles typically sit within research teams that collaborate closely with product and infrastructure groups, requiring engineers to balance scientific rigor with practical engineering constraints while contributing to publications and deployments that advance the field.
