Illumina in the Community


At Illumina, we pride ourselves on helping the community around us. Illumina in the community is a group of passionate volunteers that support many different events throughout the year.

One major event is the Cystic Fibrosis Foundation Great Strides Walk where we raise funds for cystic fibrosis research and drug development. In 2014, we raised more than $6800 for the CF Foundation.

We also volunteer at various other events such as the San Diego Festival of Science and Engineering, Rady Children’s Hospital, FACES for the Future, and MVP, which is a program that aims to ready veterans for meaningful employment within a Life Science organization.

Why Illumina?

Our employees are passionate about the work they do here.

“We’re changing the WORLD!”
“I’m proud to work at Illumina because my colleagues are the smartest (and nicest) in the world! ”
“Innovation, Oozing Creativity, and Motivation”


Ideas are Big, Outcomes are even Bigger.


As a Bioinformatics Scientist, you can choose to work anywhere because big pharma, biotech, and software companies are clamoring to hire the best. We are at the dawn of understanding how genetic data can improve lives, and nowhere else will your work have more of an immediate impact on society and human health than at Illumina. It cannot be more exciting- every experience, innovation, and effort by the scientists come together and we help make sense of all the data.

Why be a Bioinformatics Scientist at Illumina?

Cutting edge technology:

You are working with the latest NGS instruments and applications, and you get to see data from instruments like the HiSeqX (which has delivered the $1000 genome) before anyone else. You contribute to the development of new applications that quickly penetrate research labs and clinics around the world.

Great Team:

“The people are smart, fun, and passionate. I can always ask for help if I don’t know something, or when I want feedback on a new algorithm idea. I also enjoy spending time with them outside of Illumina.” - Jocelyne

Impactful Work:

“I chose industry over academia because I enjoyed the fast turnaround time of my efforts. What you’re working on now will be a product within a year or so, with a tangible impact on people’s lives. Being at the research department within industry is like an added bonus. It has all the excitement and satisfaction of exploring new ground while having a fast and tangible impact on society.”- Amirali


Each quarter Illumina recognizes employees who exemplify our company values. The Bioinformatics Scientists have been consistently awarded (8 consecutive quarters) for their collaboration, innovation, and creation of great products. The award proves the quality of talent that is in the Bioinformatics team. 

Career Development:

There are many Bioinformatics opportunities throughout Illumina. Our Bioinformatics Scientists are based in San Diego, the Bay Area, Chesterford-UK, and Madison, WI. There are opportunities within Research and Development teams working on the latest instruments. You can also specialize in particular applications such as diagnostics, oncology, prenatal health, and population sequencing.

    I applied online. The process took 2 weeks. I interviewed at Illumina (Cambridge, East of England, England).


    Handed in CV. Then invited for a video interview with pre-recorded questions. After that I was invited for a face-to-face interview with someone from HR and the manager for the team I would be in.

    Conversational interview which required me to do a short presentation at the start.
