About the Role

You would be a great fit for this role if you are an experienced engineer who will be instrumental in building the world's best LLMs by collecting and refining the essential training data that powers them. In pursuit of the best language models, your responsibility is twofold:

First Responsibility

• Identify and collect data at the scale required to feed our largest models. This involves managing a diverse set of sources, including structured and unstructured content from text and multimedia formats. Your engineering expertise is crucial in crafting the infrastructure and tools necessary to efficiently collect and manage petabytes of data.

Second Responsibility

• Experiment with various methods of extracting a balanced and comprehensive training dataset from the raw data. You will leverage your expertise in data to build datasets reflecting a hypothesis, train models, and evaluate experimental results. Through this experimentation, you will create the training datasets for our largest models.

These are critical steps in the construction of AI. With petabytes of data and numerous design decisions, each step requires careful attention. Expertise in AI is not necessary, but enthusiasm for the space and a track record of adapting to new domains is important.

Who We're Looking For

Required Experience:

• 5+ years of production software engineering experience
• Experience building large-scale data processing pipelines, with tools like PySpark, Beam, or Flink
• Familiarity with Machine Learning and NLP and willingness to learn more on the job
• Track record of adapting to new domains and a desire to use data to improve products

Additional Desired Experience:

• ML experience as an ML engineer, Data Scientist, or another similar role
• Experience with cloud platforms like AWS or Azure, or tools such as Kubernetes and Terraform
• Passionate about Conversational AI or large language models

You will be a good fit if you are proactive and have a “get things done” mindset. Given our current pace of growth and load on our systems, most people have had a significant impact during their first week at the company.
