Jobbeschreibung

At Nautilus, we have a big and important mission: improve the health of millions by unleashing the potential of the proteome to accelerate drug development and enable a new world of precision and personalized medicine. We are developing a single-molecule protein analysis platform of unprecedented sensitivity, scale, and ease of use that we believe will democratize access to the proteome – one of the most dynamic and valuable sources of biological insight. To accomplish this, we are pursuing hard scientific problems with an entrepreneurial mindset and creating a world-class team of builders, innovators, and dreamers across a wide range of disciplines.

We are hiring a Staff Scientist, Flow Cell Consumable Characterization & Reliability to join our growing team. This role will own characterization and analytical method development for flow cells on our Voyager proteomics platform, making sure flow cell performance within and across assays is reliable. You will run Voyager to functionally test flow cell formats and lots, use your material science knowledge to characterize flow cell surfaces and assemblies, and develop test methods totrack performance over time.

Responsibilities

Flow cell characterization and functional testing

• Operate the Voyager instrument as a test platform to evaluate lot-to-lot consistency, design changes, and process changes for assay-relevant performance and reliability.

• Define incoming, in-process, and lot-release tests and acceptance criteria for flow cell assemblies to verify flow cell optical, mechanical, and fluidic performance, including characterization of surface chemistry, roughness, feature geometry, defects, uniformity, assembly, alignment and stability

• Employ techniques such as atomic force microscopy (AFM), contact angle analysis, ellipsometry, XPS, and related analytical methods for surface characterization

• Correlate surface metrics with instrument performance to set meaningful surface specifications and conduct failure mode and effects analysis (FMEA)

• Design and run functional tests of reagent consumables in conjunction with flow cell assemblies, including patterned array deposition, retention, and surface passivation; investigate reagent–surface interactions such as nonspecific adsorption, surface fouling, and degradation of surface chemistry

• Translate learnings into reliable test methods, in collaboration with the flow cell manufacturing, operations team, and contract manufacturers.

• Characterize reagent stability in contact with the flow cell over time, temperature, flow, and imaging cycles, including on-instrument and in-use stability

• Support failure analysis of non-conforming flow cells (leaks, contamination, optical defects) and hand findings to the design and process owners

• Conduct accelerated and long-term stability studies of flow cells and their components

Longitudinal data and analysis

• Develop standardized assay conditions for longitudinal traceability, and maintain test instruments and fixtures in a known, calibrated state so results are traceable

• Build data pipelines and analyses that join instrument run data with flow cell, instrument, and reagent records

• Track and review longitudinal data across flow cell lots, reagent lots, and instruments; flag drift early and present trends at regular quality reviews

• Communicate quality and reliability status to R&D, manufacturing, and program leadership in clear, decision-ready terms

• Write and maintain test methods, protocols, and reports to support design transfer and scale-up
