REQUIREMENTS: - 5-6+ years of engineering experience with full-stack capabilities and strong backend depth - Real-world experience building and shipping AI applications in production (not just fine-tuning or prototyping) - Strong understanding of agent architectures, evaluations, and how to measure and systematically improve AI performance - Comfort working directly with enterprise customers in ambiguous, high-stakes environments - Strong systems thinking—ability to zoom between business problems and technical solutions - High ownership mentality focused on outcomes, not just outputs - Strong communication skills; ability to work with senior stakeholders and earn trust quickly DESIRABLE: - Background at a company with forward deployment or field engineering model - Experience building multi-agent systems in production - Domain expertise in enterprise verticals (recruiting, finance, ops, legal, etc.) - Familiarity with enterprise security, VPC deployments, or on-prem configurations - History building evaluations infrastructure or AI quality measurement tooling
