🏢 Working Here
At Illumina, bioinformaticians work at the intersection of cutting-edge sequencing technology and large-scale genomic data analysis.
Teams are organized around product lines (NovaSeq, MiSeq, BaseSpace) and research areas (oncology, reproductive health, population genomics).
A typical day involves developing and optimizing analysis pipelines, collaborating with wet-lab scientists, and pushing the boundaries of what's computationally possible with sequencing data.
The DRAGEN team, responsible for Illumina's ultra-fast secondary analysis platform, is particularly prestigious.
Work-life balance is generally good, with flexible hours and remote work options.
San Diego's biotech community creates excellent networking opportunities, and Illumina's publication-friendly culture means your work often contributes to high-impact papers.
🧬 Bioinformatics Focus
Illumina's bioinformatics focus spans the entire genomics pipeline. Key areas include:
- Secondary analysis algorithms - variant calling, alignment, base calling improvements for NovaSeq instruments,
- DRAGEN acceleration - FPGA-based genomics pipeline achieving 30x speedups,
- BaseSpace platform - cloud-based analysis workflows and app ecosystem,
- Machine learning for instrument QC and error correction,
- Population - scale genomics - analyzing datasets with millions of samples. Notable projects include the All of Us Research Program, UK Biobank sequencing, and cancer genomics partnerships with major medical centers. Technical challenges involve handling petabyte-scale data, optimizing for accuracy vs. speed tradeoffs, and developing methods for novel sequencing applications like single-cell and spatial transcriptomics.
