| Aspect | Data Engineer Data Bricks | Data Engineer Apache Spark |
|---|---|---|
| Credentials | Typically requires cloud platform certifications (Azure, AWS), Spark knowledge, and data engineering skills | Requires Spark expertise, programming skills, and often similar cloud certifications |
| Work Environment | Cloud-based platforms with integrated tools, collaborative environment, managed services | On-premises or cloud, more manual setup, flexible environment |
| Industry Usage | Popular in cloud-centric companies, data lakes, and analytics platforms | Widely used across industries for big data processing, on-premises or cloud |
Data Engineer Data Bricks focuses on cloud-based, managed Spark environments with integrated tools, while Data Engineer Apache Spark emphasizes core Spark skills applicable in various environments. Both roles require similar technical knowledge but differ mainly in platform and deployment context.

About Us
We are AI researchers and builders who understand how to curate data and RL environments that truly improve models. We curated OpenThoughts, one of the best open reasoning datasets, and have trained SOTA models such as Bespoke-MiniCheck and Bespoke-MiniChart.
We are embarked on a journey to build Environments that are entire digital worlds that can be used to push the frontier of agents.
What You'll Be Working On
You will work directly with our research team on RL environment and task creation for agent training. This means designing observation spaces, action spaces, reward signals, and success criteria for new environments — and building the infrastructure that makes world-scale RL training possible. This is a high-ownership role; you will be building novel systems, not maintaining legacy ones.
Must-Have Skills
3+ years of data engineering experience — pipelines, ETL, data modeling in production or research settings
Strong Python proficiency (numpy, pandas, Parquet, HDF5 are daily tools)
Familiarity with at least one RL framework (Gymnasium / OpenAI Gym, dm_env, or equivalent) and working knowledge of RL environment structure — observation/action spaces, reward signals, episode logic
Experience with data versioning and experiment tracking (DVC, MLflow, W&B, or similar)
Comfortable with Docker and cloud infrastructure (AWS or GCP)
Solid grasp of ML storage formats: Parquet, HDF5, JSON Lines
