About the role

Key responsibilities & impact
  • Develop algorithms that extract meaning from complex technical documents containing text, vector geometry, CAD, and raster content
  • Build document-understanding capabilities into tools powering Circuit’s long-running agentic systems
  • Improve reliability, determinism, and effectiveness of agentic systems, including planning, tool use, and failure recovery
  • Build and extend training and evaluation pipelines for core models and agents
  • Analyze production algorithm performance, identify failure causes, and drive improvements
  • Identify dataset gaps and bias through curation, labeling, or synthetic data
  • Track new research and techniques and bring promising approaches into production
  • Mentor and elevate other engineers
  • Trace extraction failures, improve models or algorithms, and validate gains through evaluations
  • Fine-tune specialized models, including LoRA on in-house models
  • Improve retrieval quality, relevance, and latency
  • Improve agent determinism by changing tools or the agent loop
  • Join customer conversations when technical depth is needed
