Job Description


Lumen is seeking a highly motivated, innovative Lead Technician for the Biologics team.

The Laboratory Technician will work closely with and support the scientists on the Biologics research team.  The work will involve several projects aimed at developing biologic therapeutics using Lumen’s spirulina-based expression system.  The individual will be expected to perform a wide range of cell biological and mammalian cell culture techniques, lentiviral infectivity assays, ELISA and molecular biology techniques, techniques in bacterial protein expression and purification, and biochemical and biophysical techniques aimed at investigating antibody-mediated toxin and virus neutralization.


The position requires the ability to work as a team member and to assist other laboratory personnel as needed. 

The position is anticipated to be central to Lumen’s acquisition and integration of new and complex technologies, and to sharing such capabilities with other teams, and as such, flexibility and independence will be essential. 

The position requires strong organizational skills and meticulous laboratory record keeping. Effective communication skills are crucial in coordinating with Lumen’s research and production scientists, in providing status updates, and in raising quality or troubleshooting issues as they may arise.


Essential Duties and Responsibilities


The major tasks for this position are as follows:

  • In vitro antibody functional screening: Tasks include mammalian cell culture, lentiviral expression and infectivity assays, bacterial cell culture in a BSL-2 environment, aseptic technique, qPCR.

  • Antibody engineering: Tasks include protein design/modeling, in silico DNA manipulation using SnapGene software, SDS-PAGE, ELISA, in vitro adherence assay, aseptic spirulina culture.

  • Bacterial Protein Expression: Tasks include expression vector cloning, culture growth and induction, analytic and preparative chromatography (SDS-PAGE, SEC, affinity chromatography); protein modification (biotinylation, covalent assembly, enzyme-mediated cleavage).

Desired Qualifications & Requirements


Education & Experience

  • BA/BS degree in biochemistry, cell biology, biotechnology or related field of study

  • Minimum of five years’ experience in protein sciences or related area.

    • Experience in aseptic technique, mammalian cell culture, BSL-2 level protocols.

    • Experience in performing cell based and biochemical /immunochemical assays (ELISA, SDS-PAGE, western blot, etc.).

    • General molecular biology skills including cloning, DNA isolation, PCR and qPCR.

    • Experience with size exclusion chromatography preferred.

    • Previous experience performing expression and purification of large quantity proteins preferred.

    • Previous experience characterizing protein-protein interactions preferred.

The successful candidate will have the following attributes:

  • Strong attention to detail and organizational skills

  • Engage with members of the team in experimental design, troubleshooting, data analysis, data interpretation.

  • Work well independently and in collaboration across various teams in the organization.

About Lumen

Lumen Bioscience was founded in early 2017 to make and commercialize ultra-low-cost biologics, such as antibodies, in our proprietary spirulina expression platform. We design and manufacture therapeutics against disease targets that have been inaccessible to the pharmaceutical industry because of the astonishingly high cost of using traditional methods to make and deliver biologic drugs. Now, for the first time, Lumen can make antibodies and other biologics at a cost that allows for daily, high-dose, oral delivery.


Our current programs focus on diseases that can be prevented or treated by an orally delivered therapeutic; the target markets are enormous, the treatment modes of action are well-researched, and the unmet medical need is obvious. We have been fortunate to have earned financial support for these programs from groups like the Bill & Melinda Gates Foundation and the NIH.  In the longer term, we believe that our unique technology–––the ability to safely deliver frequent, large doses of a wide range of biologic compounds–––will become commonplace in biopharma as the science continues to advance and uncover new opportunities in the fields of microbiome signaling, metabolism, inflammation, and oral delivery of systemic biologics.


The Lumen team works out of a beautiful lab and office facility in Fremont, a picturesque neighborhood on the north shore of Lake Union in the heart of Seattle. At Lumen, you will be challenged, you'll be inspired, and you'll be proud to be part of an innovative organization making a real impact on improving the quality of life globally.

Lumen is proud to be an Equal Opportunity Employer. All qualified applicants will receive consideration for employment without regard to race, color, religion, sex, sexual orientation, gender identity, national origin, or protected veteran status and will not be discriminated against based on disability.
