  • Architect and develop advanced Nextflow pipelines for NGS data processing, analysis, and multi-step workflow orchestration.
  • Deploy, operate, and optimize pipelines on AWS EKS and Batch.
  • Build and maintain Docker-based container environments for reproducible and portable bioinformatics pipelines.
  • Develop and maintain robust Python tooling to support workflow automation, QC reporting, monitoring, and data integration.
  • Implement workflow observability, logging, and cost-optimized execution strategies for large-scale genomic data.
  • Collaborate with sequencing, bioinformatics, and platform engineering teams to improve workflow reliability and performance.
  • Establish best practices for pipeline versioning, continuous integration, automated testing, and cloud-based deployment.
  • Ensure pipelines are highly reproducible, fault-tolerant, and suitable for production environments in regulated or high-stakes settings.

What You’ll Bring

Required Qualifications

  • 5+ years of experience in bioinformatics, computational biology, workflow engineering, or related fields.
  • Expert-level proficiency in Nextflow, including DSL2, modules, workflow optimization, and pipeline debugging.
  • Strong hands-on experience with AWS, particularly:
    • EC2 compute environments
    • S3 for cloud storage
    • EKS for workflow execution
  • Deep expertise with Docker, including custom image creation, multi-stage builds, and best practices for pipeline reproducibility.
  • Strong Python development skills with production-level experience, testing frameworks, packaging, and tooling.
  • Experience operating in cloud-native environments with distributed computing, autoscaling, cost-optimization, and workflow orchestration.
  • Solid understanding of NGS data formats, sequencing workflows, and common bioinformatics tools.
  • Strong Linux skills and experience with CI/CD systems.
  • Ability to work effectively in PST time zone (remote or onsite).

Nice to Have

  • Experience with Java/Groovy
  • Experience building and using APIs
  • Experience with Nextflow Tower or similar workflow management platforms.
  • Experience configuring Kubernetes workloads for genomics pipelines.
  • Background in synthetic biology, DNA design, or high-throughput genomic library analysis.
  • Experience collaborating with wet labs or platform teams on sequencing pipeline requirements.

A "recently separated veteran" means any veteran during the three-year period beginning on the date of such veteran's discharge or release from active duty in the U.S. military, ground, naval, or air service.

An "active duty wartime or campaign badge veteran" means a veteran who served on active duty in the U.S. military, ground, naval or air service during a war, or in a campaign or expedition for which a campaign badge has been authorized under the laws administered by the Department of Defense.

An "Armed forces service medal veteran" means a veteran who, while serving on active duty in the U.S. military, ground, naval or air service, participated in a United States military operation for which an Armed Forces service medal was awarded pursuant to Executive Order 12985.

Voluntary Self-Identification of Disability

Form CC-305
Page 1 of 1
OMB Control Number 1250-0005
Expires 04/30/2026

Why are you being asked to complete this form?

We are a federal contractor or subcontractor. The law requires us to provide equal employment opportunity to qualified people with disabilities. We have a goal of having at least 7% of our workers as people with disabilities. The law says we must measure our progress towards this goal. To do this, we must ask applicants and employees if they have a disability or have ever had one. People can become disabled, so we need to ask this question at least every five years.

Completing this form is voluntary, and we hope that you will choose to do so. Your answer is confidential. No one who makes hiring decisions will see it. Your decision to complete the form and your answer will not harm you in any way. If you want to learn more about the law or this form, visit the U.S. Department of Labor’s Office of Federal Contract Compliance Programs (OFCCP) website at www.dol.gov/ofccp.
