Principal AI Engineer

We are the company behind CKEditor — an open-source rich text editor used by millions of people around the world. We are part of Tiugo Technologies, a family of API-first developer platforms (CKEditor, TinyMCE, ButterCMS, Uploadcare) focused on content creation and digital collaboration.

Your role

We’re looking for a Principal AI Engineer to solve high-impact problems across our products and internal systems using a pragmatic combination of software engineering, systems thinking, and AI.

You are expected to use AI as part of your own daily engineering workflow - not just build AI systems for others.

This role is for a senior hands-on engineer who is comfortable operating in ambiguity, moving from problem definition to architecture to implementation, and influencing how other teams adopt AI effectively.

Key Responsibilities

• Solve high-impact problems across product and internal systems, identifying where AI or automation can create real value.
• Work closely with engineering, product, and business stakeholders to understand problems, clarify goals, and define the right approach.
• Design pragmatic, end-to-end solutions from architecture and technical plans to production-ready systems.
• Build systems involving LLMs, integrations, and multi-step or agentic workflows.
• Write production-quality code, build prototypes, and evolve them into robust, scalable solutions.
• Influence technical direction across teams, define best practices, and help others adopt AI effectively.
