You will be responsible for building automated, petabyte-scale data processing pipelines and for guaranteeing that everything they produce is efficient, reliable, and fully traceable. Our technical environment is not fixed and will evolve as our projects scale. We expect someone capable of evolving it, not only following industry trends, challenging it, and making sustainable decisions in close collaboration with our Research and Product teams.\nThe title of Engineer is used for reference purposes and may or may not be the official title of the applicant based on jurisdiction.\nKey Responsibilities\nScale and automate the data processing stack to handle petabytes of data and ensure its smooth operation.\nDesign the execution layer for pipeline stages of differing computational shape, matching each stage to an appropriate engine and keeping the pipeline saturated end to end.\nEnsure efficient use of compute resources, including GPU access for compute-intensive data processing tasks.\nMake pipelines reliable at scale, with graceful failure recovery, restartability, and observability that attributes bottlenecks and cost to the responsible stage.\nEnsure all datasets, including the intermediate outputs of each transformation stage, are versioned, reproducible, and fully traceable to meet specific and dynamic experiment needs, and are accompanied by datasheets, in accordance with internal Data Governance policies.\nPartner with the Research team to ensure the datasets you produce integrate seamlessly with the training pipelines.\nSkills and Qualifications\nA bachelor's degree in a relevant field (e.g., computer science, computer engineering, software engineering) is required.\n5+ years of experience designing, implementing, and managing large-scale distributed data processing systems, or working within large-scale distributed ML data frameworks, with recent experience using e.g. Ray, Apache Spark, workflow orchestrators, Apache Arrow, and/or Parquet.\nDemonstrated ownership of a data processing system under real throughput, reliability, and cost pressure. The specific frameworks matter less to us than evidence that you have had to reason about where a large pipeline breaks and why.\nExperience profiling and optimizing throughput and cost across heterogeneous workloads, including GPU-accelerated stages.\nExperience with dataset versioning, lineage, and reproducibility tooling.\nAbility to collaborate effectively with cross-functional teams, document best practices, and stay updated with the latest advancements in large-scale data processing and software development.\nExperience with workload managers (e.g., Ray, Kubernetes, Slurm).\nFamiliarity with containerization tools (e.g., Docker, Enroot).\nFamiliarity with data infrastructures and platforms (e.g., vector databases).\nAbout LawZero\nLawZero is a non-profit organization committed to advancing research and creating technical solutions that enable safe-by-design AI systems. Its scientific direction is based on new research and methods proposed by Professor Yoshua Bengio, the most cited AI researcher in the world. Based in Montreal, LawZero’s research aims to build non-agentic AI that learns primarily to understand the world rather than to act in it, giving truthful answers to questions based on transparent and externalized probabilistic reasoning. Such AI systems could be used to accelerate scientific discovery, to provide oversight for agentic AI systems, and to advance the understanding of AI risks and how to avoid them. LawZero believes that AI should be cultivated as a global public good-developed and used safely towards human flourishing.
