The role is hands-on and customer-facing, partnering with Forward Deployed Engineers and design customers to generalize solutions across the product. Based in Austin, TX, onsite 3 days per week.

• Work end to end with FDEs and design customers to build solutions on top of Circuit
• Generalize and package customer-specific solutions so FDEs can deploy them across accounts
• Improve underlying models, agent harnesses, and evaluation methodologies
• Debug production ML pipelines and retrieval systems, including edge cases and failure modes
• Build and maintain evaluation systems with datasets, scoring approaches, and regression testing

• Strong software engineering background with a track record of shipping production systems end to end
• Deep experience with data structures and data modeling across relational and graph databases
• Hands-on experience building with LLMs, RAG systems, and agent harnesses
• Experience working directly with customers or field teams and generalizing solutions
• Proficiency in Python and Go across a multi-service architecture
• Daily, fluent use of AI coding tools

• Vision and multimodal models on technical documents (PDFs, CAD)
• Construction, civil engineering, or industrial domain experience
• Open-source models (Qwen, DeepSeek) served with vLLM or KServe
• Hands-on PyTorch for training and fine-tuning
