About the role
About KariusKarius is a venture-backed life science startup that is transforming the way pathogens and other microbes are observed throughout the body. By unlocking the information present in microbial cell-free DNA, we're helping doctors quickly solve their most challenging cases, providing industry partners with access to the microbial landscape to accelerate biomarker discovery and clinical trials, and discover novel microbes, to ultimately reduce patient suffering worldwide.
Position SummaryThe Clinical Laboratory Scientist (CLS) I is an enthusiastic, self-motivated person with great communication skills. This individual performs high complexity laboratory testing on patient specimens, performs quality control and quality assurance procedures, interprets and reports test results under the direction of the Laboratory Director. The CLS I candidate must demonstrate a high level of individual responsibility and accountability and possess the ability to perform to the requirements listed below. The CLS I must also be comfortable in a rapidly evolving biotech start-up environment. Shift: Tuesday to Saturday, 7:00 am to 3:30 pm.
Why Should You Join Us?Karius aims to conquer infectious diseases through innovations around genomic sequencing and machine learning. The company’s platform is already delivering unprecedented insights into the microbial landscape, providing clinicians with a comprehensive test capable of identifying more than a thousand pathogens directly from blood, and helping industry accelerate the development of therapeutic solutions. The Karius test we provide today is one of the most advanced solutions available to physicians who aim to deliver better care to many otherwise ineffectively treated patients. Our test is the result of some incredible work done by our scientists, statisticians, engineers, and physicians, all driven by the same mission. You, as part of the Karius team, will be able to see how directly your work has a life-changing impact on people, and at scale.
Reports to: Senior Manager, Clinical Laboratory Operations

Primary Responsibilities• Perform routine molecular test procedures independently in an assigned area such as specimen processing, nucleic acid extraction, quantitative analysis, gel electrophoresis, PCR, library construction, sequencing and data analysis according to the laboratory’s standard operating procedures.• Perform and document routine preventive maintenance.• Perform and document reagent qualification according to approved protocols or SOPs.• Operate high-throughput integrated automation workstations. Use in-house LIMS and other infrastructure software during performance of job duties.• Ability to identify and resolve basic technical problems and ensure that corrective actions are taken whenever test systems deviate from the laboratory established performance specifications.• Maintain accurate records of work performed, perform or monitor instrument calibration and maintenance records, and generate initial reports and analysis for review as required.• Ensure that patient test results are not reported until all corrective actions have been taken and the test system is properly functioning.• Ability to revise lab SOPs under the direction of a supervisor.• Ability to identify areas for process improvement and capacity to directly support related efforts.• Perform other responsibilities as authorized by the laboratory director and require a degree of skill commensurate with the individual’s education, training or experience and technical abilities.
What’s Fun About the Job?Karius is operating at the edge of what is now known to be possible in infectious disease diagnostics. With that, comes a wave of new and incredible challenges and opportunities. To deliver on that value, you will be tapping into some of the most advanced technologies, architecting and innovating where the current solutions simply don't suffice. You will get to see how much your work really matters.
