About the role

Ethos is seeking a Senior Data Engineer to join our Data Platform team and build the internal infrastructure, services, and tooling that the rest of the company's data stack runs on. This is a software engineering role with a deep data background. You will design and operate distributed workflow systems on Temporal and Airflow, build internal platform applications (including config-driven UIs that let teams author and run their own ingestion and transformation jobs), and write Python libraries that other engineers across the company consume. You will also administer the data infrastructure we own, such as Snowflake, dbt Cloud, Airflow, and Kafka, with deep ownership of governance, reliability, and cost.

Your customers are other engineers, analytics engineers, data scientists, and operations teams. The platform you build is what makes their work possible. If you enjoy building developer-facing platforms, operating distributed systems in production, and going deep on the modern data stack, we'd like to talk to you.

Duties and Responsibilities:

- Build and operate internal data platforms, services, and distributed workflow systems (Temporal, Airflow) that the rest of the company's data stack runs on.

- Write and maintain internal Python libraries (including shared Airflow operators and frameworks) consumed by other engineering teams.

- Build and operate Temporal-based workflow systems for long-running, reliable distributed data workflows.

- Build internal data platform applications, including config-driven UIs that enable users to author and run their own ingestion and transformation jobs.

- Own cost governance across Snowflake, dbt Cloud, Airflow, and Kafka and other data platform services, including monitoring, alerting, and optimization initiatives.

- Administer Snowflake at depth: role hierarchy design, RBAC, data masking and row access policies, network policies, resource monitors, and cost governance.

- Own production code end-to-end: design, review, deploy, operate, and respond to incidents.

- Develop end-to-end automation for service and ML model deployment, ensuring smooth transition from development to production.

- Implement tools and processes to monitor the performance, reliability, and health of production systems and ML models.
