## Job description

At Personalis, we are transforming the active management of cancer through breakthrough personalized testing. We aim to drive a new paradigm for cancer management, guiding care from biopsy through the life of the patient. Our highly sensitive assays combine tumor-and-normal profiling with proprietary algorithms to deliver advanced insights even as cancer evolves over time. Our products are designed to detect minimal residual disease (MRD) and recurrence at the earliest timepoints, enable selection of targeted therapies based on ultra-comprehensive genomic profiling, and enhance biomarker strategy for drug development. Personalis is based in Fremont, California.

Summary:

In our lab, we foster a positive, friendly and team-based environment where we all pitch in to help achieve our common goals and support each other. We offer a dynamic atmosphere where you will have the opportunity to work on benches such as extractions, Library prep, and sequencing. You will also partner with our lab assistants and coordinate with them on pre-analytical & post analytical tasks.

Our Clinical Lab Scientists perform and report clinical lab testing on samples used by physicians in the diagnostic and treatment of patients. This will entail following the laboratory's procedures for specimen handling and next generation sequencing processes, test analyses, reporting and maintaining records of patient test results.

Onsite: 5 days a week

Available Shifts:

Fri-Tues, 3rd Shift

Fri-Tues, AM Shift (2 openings)

Training hours may be at different shifts.

Responsibilities:

- Maintain updated understanding and knowledge of the methods employed in the lab and the use of the resulting information by physicians through continuing education activities
- Supervise the activities of the lab in the absence of an onsite manager
- Identify problems that may adversely affect test performance or reporting of test results and either correct the problems or notify management
- Participate in activities which support all necessary licensure for the clinical laboratory, including quality management functions and on-site inspections of the laboratory
- Trains other CLS personnel and other staff in laboratory methods. Monitor the activities of non-licensed personnel as needed
- Follow the laboratory's established policies and procedures, quality control policies and activities including required documentation necessary to ensure compliance
- May be required to assist in assay development activities
- Other duties as required

Requirements:

- Bachelor’s degree, preferably in sciences or related disciplines
- California Clinical Laboratory Scientist license OR CGMBS license
- 0-4 years of experience in a clinical laboratory setting
- Beneficial to have experience with manual DNA/RNA extractions, manual library prep and working with a microtome

The hiring range for this position is $56.25 to $66.00 per hour, which may factor in various geographic regions. The PM shift would be eligible for an additional shift premium.

## Company Overview
- **One-liner**: Personalis is a precision oncology company that transforms the active management of cancer through advanced, personalized genomic testing and ultra-sensitive circulating tumor DNA (ctDNA) detection.
- **Entity Type**: Public (NASDAQ: PSNL)
- **Headquarters**: Fremont, California, United States
- **Founded**: 2011
- **Founders**: Not publicly listed as a single founder; the company was founded by a team of genomics experts from Stanford University and the broader life sciences community.

## Core Business
- **Primary industry/industries**: Precision Oncology, Biotechnology, Genomic Testing, Molecular Diagnostics
- **Target customers**: B2B — primarily oncologists, hospitals, cancer centers, and biopharmaceutical companies (for drug development and clinical trials)
- **Mission or purpose statement**: "Revealing the unique genetic signatures of solid tumors" to enable earlier cancer detection, more effective treatment selection, and better patient outcomes.

## Products & Services
- **NeXT Personal Dx**: An ultra-sensitive, personalized blood test that detects circulating tumor DNA (ctDNA) to monitor for cancer recurrence. It can detect as little as 1 tumor DNA fragment in 1 million normal cells, often identifying recurrence months to years before standard imaging. Approved for Medicare reimbursement for breast cancer (Q4 2025) and non-small cell lung cancer (Q1 2026) surveillance.
- **NeXT Dx**: A comprehensive genomic profiling test for solid tumors, used to guide therapy selection. Approved for Medicare reimbursement (Q1 2024).
- **NeXT Personal (Pharma Services)**: A highly sensitive ctDNA assay used by biopharma partners for clinical trials, enabling early detection of molecular residual disease (MRD) and monitoring of treatment response.
- **Advanced Tumor Profiling**: Ultra-comprehensive genomic profiling services for biopharma partners to optimize patient selection and biomarker strategy in drug development.

## Market Standing
- **Valuation/Market Cap**: ~$872.9 million (as of mid-2026)
- **Key Metric**: Annual Revenue — $69.6 million (2025); 2026 guidance of $78–80 million total company revenue, with NeXT Personal strategic revenue estimated at $30–32 million.

- **Growth Signals**: 26% revenue growth rate at the midpoint of 2026 guidance; over 25,000 tests delivered to date; Medicare reimbursement approvals for NeXT Personal Dx in breast and lung cancer; strong cash position of ~$233 million with no debt; 16% year-over-year headcount growth.

## Competitive Advantages
- **Ultra-Sensitive Technology**: NeXT Personal Dx can detect 1 tumor DNA fragment in 1 million normal cells, offering a "1-in-a-million" sensitivity that often detects recurrence 5–15 months earlier than standard imaging.
- **Personalized Approach**: The test identifies up to 1,800 unique DNA markers from each patient's tumor, creating a truly personalized liquid biopsy.
- **Strong IP Moat**: Over 70 patents worldwide and 38 U.S. patents, providing robust legal protection for their technology.
- **Proven Reimbursement Path**: Successfully navigated Medicare coverage for both NeXT Dx and NeXT Personal Dx, a critical barrier to entry in the U.S. diagnostics market.
- **Strategic Partnerships**: Deep collaborations with biopharma leaders (Merck, Tempus) and a strong network of academic and clinical partners.

## Strategic Focus
- **Accelerating Clinical Test Volume**: Driving adoption of NeXT Personal Dx through Medicare reimbursement and expanding clinical evidence across breast, lung, colorectal, and other cancers.
- **Expanding Evidence Base**: Conducting studies in breast, colorectal, and lung cancer, as well as immunotherapy monitoring, to broaden clinical utility and payer coverage.
- **Biopharma Partnerships**: Growing the pharma services business by enabling drug developers with ultra-sensitive MRD and therapy selection assays.
