Staff Senior Scientist, Assay Development (Library Prep)

About Glyphic:

At Glyphic Biotechnologies we plan to create the protein revolution for which scientists and researchers have been waiting. We are developing a massively parallel single-molecule proteome sequencing platform that will transform life science discovery and usher in a new era of insights into human biology and disease. To date we have raised >$80M from venture partners and non-dilutive grant funding to achieve our vision of next generation proteome sequencing.

What we are looking for in you

We are seeking an experienced hands-on Assay Development Scientist to design and perform experiments that enable the next generation of sensitive accurate and scalable single-molecule protein sequencing. Reporting to the Director of Assay Development you will leverage your molecular biology and nucleic acid biochemistry expertise to own the design optimization and troubleshooting of complex library preparation workflows for nanopore sequencing.

The ideal candidate thrives at the bench in a dynamic research environment bringing a mechanistic understanding of enzymes and the creativity to solve complex technical challenges. You iterate quickly on experimental designs communicate effectively across multidisciplinary teams and are energized by intellectually stimulating highly collaborative work.

This role will have the unique opportunity to directly shape the future of single-molecule protein sequencing enabling transformative discoveries in life science by making robust scalable and real-world-ready sequencing solutions a reality.

This is a full-time exempt in-person position with work conducted at our Berkeley CA location.

What youll do

Library preparation and assay development:

• Own the end-to-end library preparation workflow to prepare DNA molecules for nanopore sequencing including strategies for multiplexing sample barcoding second strand synthesis end repair and adapter ligation.
• Develop efficient methods for on-bead preparation and clean up to enable high sensitivity sequencing from low input material
• Develop characterization assays to monitor efficiency yield purity and construct integrity of products generated at each stage of library preparation
• Contribute to experimental design for ProSE studies and multi-cycle sequencing runs.
• Translate manual to automated workflows

Mechanistic investigation and troubleshooting:

• Investigate and resolve yield-limiting artifacts arising from protein sequencing assay chemistry.
• Diagnose and mitigate DNA library characteristics that reduce yield or bias sequencing results.
• Evaluate modified nucleotides and alternative enzymatic strategies to suppress problematic secondary structures during second-strand synthesis and end repair.
• Analyze constructs for structural issues using computational tools (SnapGene mFold NUPACK) and validate predictions experimentally.

Cross-functional collaboration and documentation:

• Work with bioinformatics to correlate library preparation variables with sequencing outcomes (read counts pore health classification accuracy).
• Partner with bioinformatics to understand how library preparation choices (barcoding strategy tailing secondary structure) affect downstream classification accuracy and signal quality.
• Work closely with oligo synthesis (modified DNA design and purity) assay development (protein sequencing workflow) automation (KingFisher and Hamilton workflows) and Bioinformatics to optimize the full sample-to-sequencer pipeline.
• Maintain rigorous experimental documentation in Confluence and Google Sheets; contribute to standardized reporting for each sequencing run.

What you need

:

• An advanced degree in Molecular Biology Biochemistry Bioengineering Chemical Biology or a related field and relevant industry experience:
  • MS/PhD with 8/6 years of experience (for Staff Scientist)
  • MS/PhD with 6/4 years of experience (for Senior Scientist)
• Deep understanding of enzymatic DNA manipulation: ligation end repair phosphorylation polymerase extension and adapter attachment.
• Experience working with chemically modified DNA or RNA and troubleshooting nucleic acid secondary structures and their effect on reaction or sequencing performance.
• Hands-on experience designing optimizing and troubleshooting library preparation workflows (manual and automated) for next-generation sequencing.
• Deep expertise in molecular biology and DNA characterization techniques.
• Experience prepping libraries with low input and DNA damage.
• Proficiency with capillary electrophoresis or gel-based QC methods for assessing library quality.
• Demonstrated ability to reason from first principles to predict reagent and condition efficacy rather than relying solely on empirical testing

Nice to have:

• Direct experience with Oxford Nanopore library preparation kits.
• Experience working with single stranded DNA or RNA library prep PCR-free preparation of DNA with modified oligonucleotides in enzymatic workflows.
• Familiarity with automated liquid handling platforms (Hamilton KingFisher) for library preparation.
• Experience with oligo-peptide or oligo-protein conjugate preparation and characterization (LCMS HPLC).
• Background in protein sequencing proteomics sample preparation or peptide chemistry.
• Comfort using AI tools (Claude Claude Code) to accelerate literature review protocol design and data analysis.

Were looking for a teammate that:

• Navigates complex team dynamics partnerships and challenges with creativity and logic.
• Operates with adaptability urgency and flexibility in evolving environments thriving in ambiguity.
• Drives work forward without needing to be asked taking responsibility for outcomes rather than tasks.
• Treats obstacles as problems to be creatively solved not reasons something cant be done.
• Applies sound judgment to the best available information testing learning and iterating.
• Shares early and directly when assumptions change results are unclear or timelines are at risk.

What you can expect from this role

Work environment:

• Collaborative culture where your ideas and expertise are valued
• Direct impact on product development and company direction

Professional growth:

• Learn from a diverse team of world-class scientists and engineers
• Contribute to first-of-their kind technologies high-impact publications and patents
