Participate in the full development life cycle for data ingestion projects, including software design, implementation, quality testing, and release.
Engage in code reviews, champion best practices, and bring new ideas to life in a collaborative environment.
Work in close cooperation with the Product team to deliver innovative new data features by discovering new data sources, increasing coverage and reliability of existing data ingestion pipelines, and connecting these to downstream feature development and data modeling.
Design, implement, and maintain robust data collection pipelines to fetch public data from third party sources.
Build resilient systems that maintain high throughput within the allowed constraints of external sources.
Monitor and troubleshoot data pipelines to ensure completeness, accuracy, and timeliness.
Track changes in external data schemas (e.g. response format updates) and adjust collection logic as needed.
Automate maintenance, alerting, and recovery for your scripts to minimize manual intervention.
Work cross functionally with our compliance team to ensure data fetching is compliant with applicable laws and regulations.

Experience we are interested in:

Solid knowledge of one or more modern software languages (Ruby, Python).
Solid understanding of RESTful systems and the principles of good API design.
Understanding of data hygiene, validation, and versioning.
Experience with REST APIs, HTTP request libraries, and HTML parsing tools.
Ability to debug and adapt in fast-changing or partially documented data environments.
Strong problem-solving skills, attention to detail, and ability to work independently.
