PRINCIPAL USER INTERFACE ENGINEER (Data Visualizations)

Who We Are

We are 8th Light, a remote-first software consultancy, we consider software design and development a craft. We’re driven by our deep commitment to excellence, and powered by our collective depth of knowledge and experience. Our team of expert developers and designers hold the title of "Crafter" to reflect our dedication to quality, our emphasis on continual learning, and our belief that software is truly a craft — something we take pride in, and value highly. We value colleagues who enjoy learning and teaching, which creates our collaborative organization.

We take a human-centered design (HCD) approach to crafting digital solutions, collaborating with the people writing code as well as those using it. We enjoy working with empathetic, passionate collaborators who value the work they do. As a team of polyglot generalists — thinkers and doers ready to take on most any challenge that we encounter, we remain positioned to help an ever growing portfolio of client partners. If this approach to product and software development resonates with you, we'd love to talk.
