ABOUT THE ROLE As an Applied AI Engineer at Handshake AI Enterprise, you'll be part of a small, expert team embedded directly inside enterprise customer environments. You'll develop a deep understanding of each customer's business, their workflows, their bottlenecks, where the real leverage is, and help translate that understanding into production-grade AI agents that measurably change how they operate. This isn't an implementation or consulting role. You'll own meaningful parts of the full stack: building and deploying agents, running evals, and iterating until performance actually moves. You'll be supported by senior teammates but expected to bring real craft and ownership to everything you touch. If you've built AI that works in the real world and want to do it at higher stakes, with better data, closer lab relationships, and a founding team that moves fast, this is the role. - Location: San Francisco, CA | 5 days/week in-office What You'll Do - Contribute to customer deployments as part of a small team, developing genuine understanding of their business and workflows - Build and deploy production-grade agents tailored to specific customer use cases - Design and run evals to measure agent performance; iterate and hill-climb until results move - Work closely with Senior Engineers, Product, and Platform teammates to ship cohesive, reliable solutions - Contribute to engineering best practices, agent patterns, and reusable frameworks as the team scales - Surface insights from deployments that inform Handshake's platform and product roadmap What We're Looking For - 2-5 years of engineering experience, with backend depth and some exposure to AI or ML systems in production - Hands-on experience building and shipping software in production, you care about whether it actually works - Familiarity with agent architectures or LLM-based systems, and curiosity to go deeper - Comfort with ambiguity, you don't need a perfect spec to start making progress - Strong communication skills, you'll interact with customers regularly and need to represent the team well - High ownership mentality, you care about outcomes, not just closing tickets Extra Credit - Any experience building or shipping AI applications in production - Exposure to enterprise environments or customer-facing engineering roles - Familiarity with evals, prompt engineering, or AI quality measurement - Domain knowledge in a specific enterprise vertical (recruiting, finance, ops, legal, etc.) PERKS Handshake delivers benefits that help you feel support
