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.

You are the engineer Illumina is looking for. In your future role at the Madison site of the global leader in genetic sequencing, you will be part of the Engineering Services team providing process-focused engineering support for the equipment and systems producing the enzymes that fuel Illumina’s sequencing and array-based solutions. You will drive process performance through process development and design, data-driven troubleshooting, process capability assessment, yield improvement, scalable equipment solutions, process control strategy, and product and technical transfer from development through manufacturing implementation. You will support fermentation vessels, purification systems, heat treatment equipment, solids conveyance, centrifuges, chromatography instruments, cold storage, analytical equipment, and emerging platform projects. You will contribute to a self-directed, diverse team by improving process capabilities, strengthening equipment reliability, enabling scale-up readiness, and applying statistical and engineering methods to sustain control. We want your curiosity, creative problem solving, communication confidence, and drive to execute.

Responsibilities

• Partner with cross-functional teams and vendors to support the design, troubleshooting, and improvement of manufacturing and laboratory systems, including fermentation, purification, PHT, solids conveyance, centrifugation, chromatography, cold storage, and analytical equipment.
