The Data Engineer Role.

We're looking for a Data Engineer who can build and scale the infrastructure powering our data platform, with a strong foundation in distributed systems and cloud-native tooling. You'll design and operate the pipelines that move, process, and prepare multi-terabyte and streaming datasets — including audio and video — for Reality Defender's detection models, and you'll work closely with ML engineers and researchers to keep that data flowing reliably at scale. Responsibilities include:

• Design, build, and operate large-scale data processing pipelines handling multi-terabyte and streaming datasets, including audio/video transcoding, feature extraction, and preprocessing workflows.

• Deploy, scale, and troubleshoot containerized workloads on Kubernetes and AWS in production environments.

• Build and maintain distributed data processing jobs using frameworks such as Spark and Ray.

• Design and operate workflow orchestration systems (e.g., Airflow) with dependency management, retries, monitoring, and alerting for production pipelines.

• Administer and tune enterprise databases, including performance tuning, backup/recovery, access control, and scaling strategies.

• Partner with ML engineers and researchers to support training pipelines, model retraining triggers, feature stores, and other MLOps workflows.

Who you are.

• Hands-on experience with Kubernetes and AWS, including deploying, scaling, and troubleshooting containerized workloads in production environments.

• Proficiency with high-performance/distributed computing frameworks such as Spark and Ray for processing large-scale datasets.

• Experience with workflow orchestration tools such as Airflow (or comparable systems like Dagster, Prefect, or Luigi) to schedule and manage complex data pipelines.

• Strong programming skills in Python and SQL; experience with Golang is a plus.

• Demonstrated track record building and operating large-scale data processing pipelines, ideally handling multi-terabyte or streaming datasets.

• Experience working with audio or video data at scale is a strong plus (e.g., transcoding, feature extraction, or preprocessing pipelines).

• Familiarity with common data transformation patterns applied to large datasets (ETL/ELT, batch and stream processing, data validation and quality checks).

• Experience designing and maintaining job orchestration systems, including dependency management, retries, monitoring, and alerting for production pipelines.

• Bonus: experience orchestrating machine learning workflows (training pipelines, model retraining triggers, feature stores, or MLOps tooling).
