Sr. AI Engineer

One of our early-stage investments is looking to bring on a Senior AI Engineer to join the founding technical team.

We’re looking for someone who has built agentic applications in production at a company with a strong engineering bar. This isn’t a “tinkering only” role. The ideal candidate is a strong backend software engineer who has moved into applied AI and enjoys building real products with LLMs.

• Build and ship agentic applications and AI-powered workflows used directly by customers
• Design and product ionize RAG pipelines and other modern LLM systems
• Own backend services that support AI features, including async processing, integrations, and data access within customer environments
• Collaborate closely with product and infrastructure engineers to turn ambiguous problems into reliable systems

• Typically, 5+ years of cumulative software engineering experience (or exceptionally strong with 3+ years)
• 1+ years building agentic applications in production (preferred)
• Alternatively, 1+ years building production RAG pipelines or other modern applied AI systems
• Strong backend engineering foundation: designing services, data models, and async processing systems
• Experience in environments with a high engineering bar for production AI systems

• Classic ML research or modeling work
• ML infrastructure / platform roles
• Pre-training focused experience

• Enterprise integrations and working in customer environments
• Workflow orchestration / job processing frameworks
• Building internal tools, developer platforms, or UI-driven software

• Early, high-impact role on a small founding team
• Opportunity to shape core AI architecture and product direction
• Strong peers, fast iteration, and real customer problems
• Competitive compensation and meaningful equity
