As an ML Infrastructure Engineer, you will play a pivotal role in providing the most reliable and performant ML Platform experience on X. Your responsibilities will include:

• Enabling teams to quickly test and iterate on their ML hypotheses via ML training capabilities, reliable GPU compute infrastructure and experimentation tools such as distributed deep learning libraries and Python notebooks
• Integrating X’s GPU compute environment with large scale data and inference pipelines
• Collaborating with cross-functional teams to integrate machine learning models into our platform
• Ensuring scalability and efficiency of machine learning systems
• Work across the stack to solve problems independently
• Mentoring junior engineers and contributing to the team's growth

**Who You Are:

We're looking for exceptional engineers who are passionate about our mission and have a strong desire to make a meaningful impact. The ideal candidate will have:

• Bachelor, Master, Post-graduate or PhD in computer science, computing engineering, machine learning, information retrieval, recommendation systems, natural language processing, statistics, math, engineering, operations research, or other quantitative discipline; or equivalent work experience
• 2+ years of industry experience (4+ for Senior) working with high traffic or large data production environments, distributed systems, backend infrastructure, recommender systems and/or deep learning applications
• 2+ years experience (4+ for Senior) with ML problems and platform tools either through first-hand modeling or close collaboration with modeling engineers or data scientists
• Working knowledge of Jupyter notebooks and Python, plus experience with a compiled language, such as Scala, Java or C++

**Nice to haves

• You stay up-to-date on Machine Learning and Deep Learning industry trends
• You have low level understanding of compute systems such as distributed storage, NVIDIA drivers and CUDA toolkits
• You are comfortable with Linux systems
• You have worked with Slurm scheduler, Puppet or Ansible

At X, our small but fast-paced team values innovation, creativity, and a strong commitment to our mission. As an ML Infrastructure Engineer/ Senior ML Infrastructure Engineer, you'll have the opportunity to make a significant impact on the future of X and our aspiration to build the Everything App.
