Nextflow Jobs (NOW HIRING)

Job Description

Field of Research:

Computational biology/bioinformatics with emphasis on spatial transcriptomics, proteomics, and immunosequencing using Pixelseq and an immune receptorfocused multimodal expansion ("ImmunoPixelseq"). Work includes NGS data processing, spatial barcode mapping, singlecell & spatial analysis, and cell segmentation in brain, tumor, and other tissues.

Purpose of the Research project(s):

To build and operate robust, reproducible pipelines that transform raw sequencing + barcode map into highquality, spatially resolved singlecell datasets; to deliver diseasefocused analyses that advance mechanistic discovery and translational hypotheses (e.g., tumor microenvironment, neuroanatomical circuits).

Duties and Responsibilities:

Endtoend data processing (BCL/FASTQ QC counts) - 20%
Demultiplexing, adapter/quality trimming, UMI handling, alignment/quantification; generation of MultiQC reports and run manifests.

Spatial barcode mapping & registration - 15%

Build/validate barcode(x,y) maps for Pixelseq; error correction; join gene/protein counts to spatial coordinates; QA of mapping rates.

Segmentation & QC - 20%
Apply/benchmark nuclei or wholecell segmentation (e.g., Cellpose/StarDist/SAM); maintain curated masks and QC thumbnails.

Downstream singlecell & spatial analysis - 20%
Create annotated data objects (e.g., AnnData/Seurat); normalization, clustering, label transfer; spatial neighborhood/domain analysis; multiomic modeling for RNA+protein where applicable.

Pipeline automation & reproducibility - 10%
Implement/maintain Snakemake/Nextflow workflows with containers (Apptainer/Docker), CI tests, and clear documentation.

Project support, collaboration & reporting - 7%
Prepare figures/tables; concise analysis memos; contribute to methods sections.
Light server/environment maintenance & upgrades (DevOpslite) - 5%
Build and update containerized analysis environments, maintain conda/uv environments.
DevOpslite & data stewardship - 3%
Maintain analysis environments/containers; basic SLURM job scripts; coordinate with IT on storage/backup hygiene.

Visa Eligibility

This position is eligible for H-1B sponsorship.

Minimum Requirements:

Bachelor's Degree in CS, Applied Math, Bioinformatics, Computational Biology, ECE and one year of relevant experience with Computational biology/bioinformatics.

Equivalent education and/or experience may substitute for minimum qualifications except when there are legal requirements, such as a license, certification, and/or registration.

Additional Requirements:

1. Programming & data: Python (numpy/pandas), basic R (Seurat/tidyverse), bash; Git; Linux.
2. NGS data processing: BCLFASTQ demultiplexing; adapter/quality trimming; UMI handling; QC with MultiQC; alignment/quantification to reference.
3. Spatial omics: Pixelseq barcode(x,y) mapping concepts; creation of spatially annotated objects (AnnData/Seurat).
4. Segmentation: Practical use of Cellpose/FICTURE (or similar); basic image QC.
5. Singlecell & spatial analysis: Normalization, clustering, label transfer; spatial neighborhood/domain analyses (e.g., with Squidpy/Giotto).
6. Reproducibility & automation: Snakemake or Nextflow; containerization (Apptainer/Docker); clean documentation; basic SLURM job submission.
7. Communication: Clear writing of READMEs, short analysis memos, and figure captions for collaboration with biologists/clinicians.
8. Linux/HPC usage; Slurm job submission, resource requests, and environment management.

Desired Requirements:

1. Probabilistic modeling: scVI/scANVI/totalVI for RNA and RNA+protein integration.
2. GPU experience: PyTorch/CUDA for segmentation/model inference.
3. Data stewardship: DVC or equivalent data versioning; basic dashboarding/monitoring (Prometheus/Grafana).
4. Domain breadth: Prior coursework/research in biochemistry or genetics; interest in medical/MDPhD pathways.
5. DevOpslite: GitHub Actions CI, environment pinning, reproducible reference bundles, and runbooks.
6. Experience assisting with server upgrades in collaboration with IT (CUDA/cuDNN & GPU driver stacks, Slurm client updates, module systems).
7. Basic familiarity with configuration/monitoring for research workflows (e.g., Ansible basics, Prometheus/Grafana dashboards) under IT guidance.
8. Storage and I/O awareness for highthroughput data (scratch NVMe vs. bulk); performance troubleshooting for pipelines.
