Job Description
Overview: TekWissen is a global workforce management provider headquartered in Ann Arbor, Michigan that offers strategic talent solutions to our clients world-wide.
Position: Bioinformatics Engineer
Location: Foster City, CA 94404
Duration: 12 Months
Job Type: Temporary Assignment
Work Type: Onsite Bioinformatics Engineer - T2T Genome Assembly (Non model Organisms) - This is a 12 month contract Bioinformatics Engineer role to deliver telomere to telomere (T2T) reference genomes for non model organisms by building and operating long read assembly and curation pipelines using PacBio HiFi and/or Oxford Nanopore, with complementary data (Hi C/Omni C, Strand seq, optical maps, short reads) as needed.
- You will partner with wet lab and computational teams to troubleshoot complex genomes (polyploidy, high heterozygosity, repeats) and package results for internal and external release.
Key Responsibilities - Plan assembly approaches for non model organisms (data QC, genome profiling, contamination screening, coverage targets) and advise sequencing strategy.
- Run and iterate long read assemblies and consensus refinement (e.g., hifiasm/Verkko/Flye/Canu; polishing as appropriate) toward chromosome scale, T2T quality results.
- Resolve haplotypes and complex ploidy/heterozygosity (e.g., trio binning; Hi C/Strand seq assisted phasing) and deliver haplotype resolved assemblies when required.
- Scaffold and curate assemblies with long range data (e.g., Hi C/Omni C, Strand seq, optical maps): detect/resolve mis joins, close gaps where feasible, and document curation decisions.
- Benchmark quality and completeness (e.g., k mer spectra/Merqury, BUSCO, QUAST, read mapping), including repeat/centromere/telomere assessments to guide iterative improvements.
- Productionize workflows (Nextflow/Snakemake/WDL) with containers (Docker/Singularity) across on prem HPC and AWS; produce clear reports, docs, and release packages.
Required Qualifications - PhD in bioinformatics, computational biology, computer science, or related field.
- Proven de novo assembly experience on long reads (PacBio HiFi and/or ONT), including tuning and iterative improvement.
- Assembly QC/validation expertise and ability to diagnose common failure modes in complex genomes.
- Strong scripting/programming skills (Python and/or Bash) in Linux; solid software engineering practices (Git, testing, documentation).
- Workflow + compute operations experience: Nextflow/Snakemake/WDL; running large genomics workloads on on prem HPC (e.g., Slurm/LSF) and AWS (e.g., Batch/HealthOmics), with cost aware scaling.
Preferred Qualifications - Deep genome assembly and/or annotation experience in non model organisms (repeat annotation and evidence driven gene annotation is a plus).
- Demonstrated progress toward T2T completeness (telomeres/centromeres/segmental duplications) and chromosome scale scaffolding.
- Evidence of impact (reference releases, preprints/publications, community datasets) is a plus.
Additional Skills (Nice to Have) - Annotation evidence integration by RNA-Seq and delivery of genome browser enabled tracks.
- AWS pipeline operations (S3 data transfer, Batch or HealthOmics) and strong cross functional communication (clear status updates, documentation, handoffs).
