Software Engineer, Data Infrastructure

An engineer building the data infrastructure behind trustworthy AI

Factagora's Temporal Knowledge Graph runs on accurate, trustworthy data. Beyond collecting, processing, and storing data, the core of this role is making sure the research and product teams can genuinely trust that data. Systems that started simple to help us move fast become bottlenecks as we grow. In this role you'll take ownership of that transition:
fixing what needs fixing, and redesigning what needs redesigning
.

• Designing and building large-scale data ingestion pipelines (batch and streaming)
• Designing and operating Knowledge Graph and ontology data stores (Graph DB, vector DB, and more)
• Building data quality monitoring, anomaly detection, and automation pipelines
• Operating the data platform and feature store used by our Research Engineers
• Designing cloud-based data infrastructure architecture and optimizing cost
• Designing and operating data security, access control, and privacy policies

• 2+ years of software development experience, or equivalent practical ability
• Experience building data pipelines in at least one of Python, Scala, or Java
• Experience designing and operating SQL and No
  
  SQL databases
• Experience building data infrastructure on a cloud platform such as Azure
• Experience with large-scale data processing and performance optimization

• Experience designing and operating a Graph DB in a production service
• Experience building streaming or large-scale batch processing pipelines
• Experience operating a vector DB or embedding-based search infrastructure in production
• Experience designing or operating MLOps or a feature store
• Experience working with data pipelines in the media, news, or content platform domain
• Experience designing scalable infrastructure with limited resources at a pre-Series A startup

• You've built systems that actually run in production, with a bar for accuracy, cost, and usability all at once
• You can tell the difference between what needs fixing and what needs redesigning. You value making the right call at the right time over a perfect redesign
• You believe data quality is the foundation of AI trustworthiness
• You find purpose in designing infrastructure, not just operating it, so researchers and engineers can do their best work
• When something breaks or data looks off, you dig into the root cause and prevent recurrence instead of patching it
• You genuinely connect with Factagora's mission of building a trustworthy AI and information ecosystem
