Software Engineer (Research Data Platform)

• The Research Data Platform team builds the tools that Anthropic’s researchers use every day to manage, query, and analyze the data that goes into training and evaluating frontier models
• We power the internal applications researchers rely on to monitor RL runs, explore finetuning datasets, and understand what’s happening inside their experiments
• This role sits closer to the research workflow than a typical data infrastructure position: you’ll often embed with research teams, build ML-specific tooling alongside them, and leverage what our Data Infrastructure team has already built rather than reinventing it
• Build and operate data pipelines that extract data from research training runs and land it in storage systems that are easy and fast to query
• Work closely with researchers to design and build APIs, libraries, and web interfaces that support data management, exploration, and analysis
• Develop dataset management, data cataloging, and provenance tooling that researchers use in their day-to-day work
• Embed with research teams to understand their workflows, identify high-leverage tooling opportunities, and ship solutions quickly
• Collaborate with adjacent teams to build on existing systems rather than reinventing them

Benefits

• Comprehensive health, dental, and vision insurance for you and your dependents
• Inclusive fertility benefits via Carrot Fertility
• 22 weeks of paid parental leave
• Flexible paid time off and absence policies
• Mental health support for you and your dependents
• Competitive salary and equity packages

• Life and income protection plans
• $500/month flexible wellness and time saver stipend
• Commuter benefits
• Annual education stipend
• Home office stipends
• Relocation support for those moving for Anthropic
• Daily meals and snacks in the office- We’re looking for engineers who love working directly with users and who excel at building data products — the pipelines that move data out of training runs into queryable storage, and the APIs, libraries, and services researchers use to manage and explore it
• We do not require prior ML or AI training experience. If you enjoy working closely with technical users, learning new domains quickly, and building tools people actually want to use, you’ll pick up the research context fast
• Are results-oriented, with a bias towards flexibility and impact
• Care about the societal impacts of your work
• Have significant software engineering experience, particularly building data-intensive applications or internal tooling
• Want to learn more about machine learning research
• Pick up slack, even if it goes outside your job description
• Enjoy working directly with users, gathering requirements iteratively, and shipping things that get adopted
• ML experiment tracking or metrics platforms
• High-volume time series data — ingestion, storage, and efficient querying
• Complex data visualization and full-stack web application development
• Large-scale ETL, columnar storage formats, and query engines (e.g., Spark, BigQuery, DuckDB, Parquet)
• Working in environments where engineers partner closely with quantitative users — research labs, trading firms, observability or analytics startups
• Bachelor’s degree or an equivalent combination of education, training, and/or experience
• Data cataloging, lineage, or metadata management systems
• Required field of study: A field relevant to the role as demonstrated through coursework, training, or professional experience
• Not all strong candidates will meet every single qualification as listed, we urge you not to exclude yourself prematurely and to submit an application if you’re interested in this work
