Responsibilities

As a Staff Software Engineer – Data at Character, you will work on a diverse set of projects spanning both software engineering and data engineering domains. Your initial focus will be on three key areas:

• Activate our data flywheel: develop data pipelines and collaborate with ML researchers to continuously improve AI models and align them with human feedback.
• Evolve our A/B testing framework: conduct a thorough analysis of the current framework and prepare it for the next generation of data‑driven product growth.
• Enable product team insights: design, implement, and maintain a robust data warehousing solution for consistent, reliable reporting and ease of data exploration as we better understand our users.

Additionally, you may work on optimizing database and application performance, cleaning pre‑training datasets, and contributing to a service‑oriented architecture alongside the Staff Software Engineer – Application.

• A.S. in Computer Science or equivalent experience.
• 4+ years of minimum experience in data engineering within a consumer‑facing technology company.
• Experience building data warehousing and data pipelines with Big Query, dbt, Ray, Beam, and Spark.
• Experience designing, implementing, and supporting end‑to‑end A/B tests.
• Experience managing Elasticsearch, Spanner, and Postgres.
• In‑depth experience building and managing infrastructure in a cloud environment, especially GCP.
• Strong Python and SQL experience.

• Experience tuning databases and optimizing query performance.
• Experience setting up containerization with Docker and Kubernetes.
• Familiarity with PyTorch or JAX.
• Excellent problem‑solving skills and the ability to work independently and as part of a team.
• Strong communication and collaboration skills.
