About Us Essential AI is building an open platform to fuel and accelerate AI breakthroughs globally. Our open models, robust tooling, reproducible pipelines, and evaluation frameworks are designed for collaboration and contribution, empowering others to build, iterate, and innovate faster.

Essential AI's technology and products have the means to shape AI advancements while supporting scalable and sustainable business models. Powerful AIs don't trace their origins to singular breakthroughs, but from an amalgam of improvements, incremental and large. Essential AI creates the ideal environment to catalyze these advancements, enabling a steady path to sustained frontier capabilities.

The Role

The ML Infra Platform Engineer will be responsible for architecting and building the compute infra that powers the training and serving of our models. This requires a full understanding of the complete backend stack → from frameworks to compilers to runtimes to kernels.

Running and training models at scale often requires solving novel system problems. As an Infra Systems Engineer, you'll be responsible for identifying these problems and then developing systems that optimize the throughput and robustness of distributed systems. With proven experience building large-scale platforms, you will be responsible for building and advancing our systems that allow research and engineering organizations to iteratively develop, test, and deploy new features reliably, with high velocity, and with a frictionless-fast development cycle.

What You’ll Be Working On

• You will help oversee and drive the vision of how we should build, test, and deploy models, while taking ownership and transform state-of-the-art development experience for research
• Design, build, and maintain scalable machine learning infrastructure to support our model training, inference and applications
• Design and implement scalable machine learning and distributed systems that enable training and scaling of LLMs. Work on parallelism methods improve training of in a fast and reliable way
• Working on lower levels of the stack to build high-performing and optimal training and serving infrastructure, including researching new techniques and writing custom kernels as needed to achieve improvements

What we are looking for

• A strong understanding of architectures of new AI accelerators like GPU, TPU, IPU, HPU etc and their tradeoffs. Knowledge of parallel computing concepts and distributed systems.
• Experience with Kernels, Low precision training, MoE.
• Prior experience in performance tuning of training and/or inference LLM workloads. Experience with MLPerf or internal production workloads will be valued.

We encourage you to apply for this position even if you don’t check all of the above requirements but want to spend time pushing on these techniques.
