Ethos is hiring a Senior Data Engineer

TensorOps is looking for a Senior Data Engineer to build and maintain the real-time data ingestion pipelines that power our property analytics platform. You will architect event-driven data flows to stream data from external sources into our operational PostgreSQL database, ensuring data is reliably ingested, validated, and ready for downstream analytics teams.

What You'll Do

• Design and implement event-driven pipelines using AWS services (Lambda, EventBridge, Kinesis/MSK, SQS) to ingest data from external sources in real-time.
• Build and maintain streaming data pipelines between HubSpot CRM and PostgreSQL, handling webhook events, API polling, and CDC patterns for sub-minute data freshness.
• Develop robust connectors for third-party APIs, webhooks, and data sources, ensuring reliable data capture with proper error handling and retry logic.
• Implement schema validation, data type checking, and automated quality gates at the ingestion layer to prevent bad data from entering the system.
• Manage relational and analytical databases, ensuring performance, scalability, and cost efficiency.
• Deploy and manage AWS resources (Lambda, RDS, EventBridge, CloudWatch, S3) for scalable data solutions.
• Build comprehensive monitoring dashboards and alerting systems to track pipeline health, data freshness, and error rates.
• Optimize ingestion pipelines for throughput, latency and efficiency while handling high-volume data streams.
• Maintain clear documentation of pipeline architecture, data flows, API integrations, and operational runbooks.

What We're Looking For

• 5+ years of experience as a Data Engineer focused on data ingestion and pipeline development.
• Strong proficiency in Python for building ETL/ELT pipelines, API integrations, and data validation logic.
• Hands-on AWS experience with Lambda, EventBridge, Kinesis/SQS, RDS/PostgreSQL, CloudWatch, and S3.
• Proven experience with event-driven architecture: event buses, message queues, webhooks, and streaming architectures.
• Experience with Kafka, Kinesis, or similar streaming platforms; understanding of CDC and real-time data patterns.
• Strong experience with REST APIs, authentication methods (OAuth, API keys), rate limiting, and error handling.
• Comfortable writing efficient SQL and understanding database constraints, indexing, and connection pooling for PostgreSQL.
• Strong written and verbal English communication skills for technical documentation, code comments, and daily collaboration with Australia and Spain-based team members.
• Analytical mindset with ability to debug complex pipeline issues and implement robust error recovery.
• Comfortable working remotely with distributed teams across different time zones.
