We are looking for a Senior AI Agent Engineer to take the lead in shaping our AI strategy and building intelligent systems into our platform. You won’t just be writing code, you’ll guide the company’s AI direction, design production-ready workflows, and set the standards for how we deliver safe, scalable, and auditable AI features.
You’ll design and deploy agent workflows, build evaluation pipelines, and ensure outputs are safe and explainable. Working directly with the founding team, your impact will shape both our technology and how customers experience our product.
This is a hands-on, high-ownership role where you’ll go from prototype to production, orchestrating integrations, deploying services, and creating the frameworks to scale AI safely.
