Senior Design Engineer

We’re looking for an exceptional design engineer. If you excel at crafting beautiful tools, thrive on taking ownership, and can drive features from concept to implementation—we’d love to talk.

At Lemni, we’re redefining how businesses interact with their customers. Lemni is a completely new approach to customer experience. Our tools allow businesses to create Ai Agents that deliver personal customer care at scale. From designing collaborative editors to developing cutting-edge Ai agents and developer tools, we tackle a wide array of exciting challenges.

While knowledge gives us the foundation to build, it’s imagination that lights the way forward. We believe that thinking beyond the known is how breakthroughs happen. At Lemni, we explore boldly, hold strong opinions loosely, and question continuously. It’s not just about understanding what exists—it’s about envisioning what could be.

As a Senior Design Engineer, you’ll play a key role in shaping our products. You’ll take ownership of features, guiding them from ideation to implementation, and ensure they meet our high standards for design and functionality. Your craft will help drive the success of Lemni.
