Ceartas is your internet delete button. As an AI-powered content protection platform built for the modern internet, we help creators, platforms, and brands protect what they've built - from piracy and leaks to impersonation and deepfakes.

At Ceartas, we lead the way in AI-powered brand protection, copyright law, and digital security, safeguarding the integrity of content creators, brands, and enterprises worldwide. As we scale rapidly, we're looking for a Data & Python Software Engineer to drive innovation in our data pipelines and crawling technologies. In this pivotal role, you'll collaborate with our CTO and Head of Engineering, steering our Data Engineering Team toward developing groundbreaking solutions for digital security challenges.

THE ROLE

What You'll Own

Build Scalable Data Pipelines:

Design and develop robust ingestion and processing pipelines that support large-scale web data extraction and brand protection workflows. Ensure that data moves reliably from collection through processing to storage while maintaining performance, resilience, and operational stability at scale.

Engineer Backend Services and APIs:

Design, implement, and maintain high-performance backend services and APIs that power internal platforms and external integrations. Deliver well-structured, maintainable systems using Python-based frameworks while ensuring scalability, security, and long-term extensibility.

Ensure Data Quality and Governance:

Own data validation, consistency, and governance across ingestion, storage, and serving layers. Establish clear standards for schema design, transformation logic, and monitoring to guarantee trustworthy, production-grade datasets that can be reliably consumed across the organization.

Optimize Performance and Reliability:

Continuously improve system efficiency through performance tuning, cost optimization, and architectural enhancements. Implement logging, metrics, and tracing to monitor production systems, diagnose issues quickly, and maintain high reliability under growing workloads.

Own Production Systems End-to-End:

Take full lifecycle ownership of deployed systems, from design and implementation to operation, iteration, and long-term improvement. Collaborate closely with product and engineering stakeholders to deliver features end-to-end, ensuring that systems remain scalable, maintainable, and aligned with evolving business needs.
