What if the work you did every day could impact the lives of people you know? Or all of humanity?

At Illumina, we are expanding access to genomic technology to realize health equity for billions of people around the world. Our efforts enable life-changing discoveries that are transforming human health through the early detection and diagnosis of diseases and new treatment options for patients.

Working at Illumina means being part of something bigger than yourself. Every person, in every role, has the opportunity to make a difference. Surrounded by extraordinary people, inspiring leaders, and world changing projects, you will do more and become more than you ever thought possible.

We are seeking a Senior Web Engineer for our Global Information Services Commercial team, to help us build our next-generation customer dashboard and ecommerce site - MyIllumina.

You see complexity as a challenge, not an obstacle. You choose the things that are hard, understanding that the difficult road leads to the greatest reward. You understand that what you don’t know will always dwarf what you do and expend your efforts accordingly. You are deeply enthusiastic about building systems that make a difference. You never settle for ‘good enough’ and know that even the smallest part, or the simplest specification can make the difference between good, and great.

Our Global Information Services Commercial team oversees the development and management of Illumina’s global cloud-based digital experience solutions such as illumina.com.cn, ecommerce and customer dashboard. You will be working on various innovative tools and technologies in a cloud-based enterprise applications stack that supplies customer centric digital experience solutions worldwide to enable the transformation of human health through DNA sequencing.

At Illumina, you will collaborate with internal partners to lead end-to-end projects. We will turn to you for your deep technical ability and innovative thinking. Our goal for you is to help us deliver impressive digital experiences. You will have the success of delivering against project goals. To be successful, you are experienced, collaborative, process-friendly, and can work within timelines on multiple projects simultaneously.
