Lead AI Developer Tooling Engineer

Grow your engineering career building the developer tools that power AI automation for the world's largest enterprises.

This role is based at our headquarters in McLean, Virginia. Appian was built on a culture of in-person collaboration, which we believe is a key driver of our mission to be the best. Employees hired for this position are expected to be in the office 5 days a week to foster that culture and ensure we continue to thrive through shared ideas and teamwork.

We believe being in the office provides more opportunities to come together and celebrate working with the exceptional people across Appian.

Appian Engineering spans the full depth of our platform: from the foundational layers that power enterprise scale, to the AI capabilities redefining what automation can do. We operate in a highly collaborative, fast-paced environment focused on technical precision, continuous learning, and high code quality. By joining our team, you will solve real-world problems that directly shape how Appian delivers our AI-Powered Process Automation platform to enterprises around the world.

As a Lead AI Developer Tooling Engineer, you will serve as a technical linchpin for the team building the tools Appian's own engineers rely on — IDEs, CLIs, code-analysis, and CI/CD workflows — and the layer that brings AI capabilities into their daily development. Equipped with cutting-edge AI tooling yourself, you'll design and deliver developer experiences of real sophistication, shape engineering practices, and deepen your expertise while ensuring flawless Enterprise-Grade Orchestration.
