Karius is hiring a remote Customer Success Representative I to support physicians, laboratory personnel, hospital administrators, and field sales teams. The official listing pays $26-$36 per hour and allows the job to be performed remotely in the United States or in a hybrid arrangement in Redwood City, California.
Applicants need at least three years of customer support or service experience in healthcare or a related industry, including telephone support. The schedule is fixed at 7:00 a.m.-4:00 p.m. Pacific, Tuesday through Saturday, and the listing classifies the position as a Temporary Agency Worker. The official application was active when checked on September 30, 2026.
What Is Karius?
Karius is a life science and healthcare technology company that uses microbial cell-free DNA and genomic analysis to help clinicians identify infectious-disease pathogens from a blood sample.
The Customer Success team helps medical customers understand the ordering and sample process, obtain status updates, and route clinical questions to the correct internal experts. This means the representative is not providing ordinary retail support; the customers include healthcare professionals dealing with diagnostic testing and sensitive patient information.
Pay and Benefits
Karius lists an hourly range of $26-$36. The page does not explain how experience, location, or agency terms affect placement within that range.
The opening is labeled Temporary Agency Worker rather than a regular Karius employee position. The listing does not describe health insurance, paid time off, retirement benefits, holidays, equipment, agency identity, assignment length, conversion potential, or guaranteed weekly hours. Applicants should confirm all of those terms with the recruiter or staffing agency.
Job Highlight: Customer Success Representative I
The representative responds to inbound requests from physicians, laboratory personnel, and hospital administrators through phone, email, and help tickets. Common needs include obtaining missing sample information, giving status updates, coordinating with the production laboratory, and escalating questions about Karius test results to Medical Affairs.
Phone work is explicitly required, so this is not a no-phone or written-only opportunity. The role also handles protected health information and supports a specialized diagnostic product, which makes accuracy, discretion, and comfort communicating with clinical professionals especially important.
Key Responsibilities
- Respond to customer questions through phone, email, and help tickets
- Support physicians, laboratory personnel, and hospital administrators
- Contact laboratories and clinicians to obtain information needed for processed samples
- Provide timely sample and testing-status updates
- Escalate questions about test results to the Medical Affairs team
- Coordinate with production laboratory staff on sample processing and reporting problems
- Support Sales and Business Development teams when customer issues require follow-up
- Protect personal health information and follow applicable privacy procedures
- Maintain professional, accurate, and knowledgeable communication
Qualifications
Karius requires:
- At least three years of customer support or service experience in healthcare or a related industry
- Telephone-based support experience
- Ability to work Tuesday through Saturday from 7:00 a.m. to 4:00 p.m. Pacific
- Ability to handle customer contacts professionally and knowledgeably
- Ability to work independently
- Careful handling of personal health information
- Strong verbal and written communication
- Basic Microsoft Office and Google Workspace skills
A bachelor's degree or higher in Biological Sciences is preferred. Experience working with hospital laboratories and clinicians is also preferred, along with Zendesk and Salesforce experience. These preferences may strengthen an application, but the listing separates them from the required three years of healthcare support and telephone experience.
Resume Keywords
Use these terms only when they truthfully match your background:
- Healthcare customer support
- Telephone support
- Physician support
- Hospital laboratory support
- Customer success
- Help tickets
- Sample processing
- Status updates
- Escalation management
- Medical Affairs
- Salesforce
- Zendesk
- Protected health information

Applicants can strengthen relevant resume bullets by accurately naming call or ticket volume, healthcare customers supported, response-time standards, cases resolved, escalations coordinated, or improvements in documentation accuracy.
Location and Schedule
The official page lists Redwood City, California, hybrid or Remote USA. The remote option therefore covers the United States broadly, but the listing does not name excluded states or say whether temporary agency hiring is available in every state. Applicants should confirm state eligibility before relying on the remote label.
The required schedule is Tuesday through Saturday, 7:00 a.m.-4:00 p.m. Pacific. That becomes 8:00 a.m.-5:00 p.m. Mountain, 9:00 a.m.-6:00 p.m. Central, and 10:00 a.m.-7:00 p.m. Eastern.
Karius states that no travel is required. The public page does not specify assignment length, weekly-hour guarantee, overtime, holidays, training hours, equipment, internet requirements, or whether the agency or worker supplies the computer.
Closing Notes
This opportunity may fit an experienced healthcare support professional who is comfortable speaking with physicians and laboratory teams, protecting patient information, working a Tuesday-Saturday schedule, and learning a specialized diagnostic product.
The strongest advantages are the $26-$36 hourly range, broad U.S. remote option, no travel, and direct experience in healthcare technology. The biggest catches are the three-year healthcare-support requirement, required telephone work, Saturday schedule, and temporary agency classification with no public benefit or assignment-length details.
