Our Blind Spot

We are growing faster than our infrastructure can keep up, and we are using duct tape to keep our systems reliable while continuing to ship new features. We are looking for a ML Software Engineer to join our AI team and build the intelligence layer that makes our agents think, learn, and act, while another part of the team focuses on scalability and reliability. You will join a founding team of young, talented engineers and have the opportunity to completely rethink the trillion-dollar supply chain industry.

Key Responsibilities

• Design and ship Computer Use Agent (CUA) capable of autonomously navigating and operating desktop applications.
• Architect and maintain the Knowledge Base, the continuously evolving memory, that makes our agents smarter, more personalized, and more accurate over time.
• Integrate AI systems within our platform to automate manual workflows and surface actionable data insights.
• Implement LLM-as-a-Judge evaluation frameworks to ensure reproducibility and consistent quality across agent behaviors.
• Monitor and troubleshoot production issues affecting our AI workloads, and promptly assist the team by providing data and insights to expedite resolution.
• Write clean, tested, maintainable code and documentation.
