Join Us at Pura—Reimagining Fragrance for the Future

At Pura, we believe life is better when it smells good. Fragrance has the unique power to transform spaces, elevate moods, and create lasting memories. But we know it can do even more. That’s why we’re pioneering the future of fragrance, combining cutting‑edge smart home technology with premium, clean scents to create personalized, meaningful experiences in every home.

We’re not just a fragrance company—we’re on a mission to change the way people experience scent. At Pura, we are redefining fragrance as a critical element of design, on par with color, texture, sound, lighting, and furniture. We call this Scent Design
—transforming scent from an afterthought into an intentional, skillful component of every space. By blending artistry and science, Pura allows users to design their own “scents capes” that enhance daily life and craft environments that feel as good as they smell.

Our journey began with two innovators, Richie Stapler and Bruno Lima, and their shared vision of revolutionizing how we experience fragrance. Since then, Pura has grown into a company that sells a fragrance every 3.7 seconds, partnering with iconic brands like Curio, Anthropologie, and Disney. We’ve been recognized as the Fastest Growing Company in Utah, and we are passionate about making scent a core part of life’s most memorable moments.

As a Staff Firmware Engineer at Pura, you will play a pivotal role in shaping the core technology that powers our innovative IoT fragrance devices. Leveraging your expertise in embedded systems, wireless communication protocols and cloud connectivity, you will drive the development of robust and scalable firmware solutions. You will help us inspire a belief in the power of fragrance to craft and elevate memorable moments for our Owners.

This is your chance to make an impact in a high‑growth company that’s redefining the way people experience scent.
