Senior AI Tools Engineer - Developer Experience

About the role

We're looking for a Senior AI Tools Engineer - Developer Experience with deep expertise in C++ or Golang to lead the evolution of our backend platform and tooling. While our ecosystem has historical roots in Elixir/Scala, we are shifting our focus toward strengthening our core infrastructure with high-performance programming languages.

You should be comfortable working independently across system boundaries and mentoring engineers while driving technical strategy. Note: While this is primarily a C++ or Go role, we maintain a footprint of Rust-based tools. A cursory knowledge of Rust or a willingness to interface with Rust-based infrastructure is critical for this role We're particularly interested in engineers excited to learn and integrate AI-powered coding tools (e.g., Claude Code, Cursor) into their daily workflow to boost velocity and code quality. Prior experience with such tools is a plus.
