Lab Technician (Overnight Shift)

Lab Technician

Gaithersburg, Maryland, United States

At GeneDx, we don't just diagnose rare diseases we redefine what's possible in precision medicine. With one of the world's largest, rare disease datasets, we turn genomic data into answers that change lives and accelerate discovery. Patients and families around the world are counting on us to lead with bold ideas, relentless focus, and drive to end the diagnostic odyssey.

The Lab Technician may support a range of laboratory functions including but not limited to the preparation, processing, and analysis of clinical DNA specimens in support of genetic disease diagnosis. Responsibilities include adherence to established specimen handling protocols, execution of both manual and automated testing methods, documentation of issues impacting test quality, and compliance with all quality control and proficiency testing requirements. With a focus on accuracy, procedural consistency, and operational efficiency, the role contributes to reliable diagnostic outcomes and supports broader laboratory testing services. The Lab Technician collaborates closely with supervisory staff and team members to ensure performance metrics are met and to maintain a high standard of laboratory practice across workflows and platforms.

Job Responsibilities

• Follow established standard operating procedures for specimen handling, processing, test analysis, record keeping, and reporting of results to team leads, supervisors, and test managers.
• Process samples using manual and automated methods aligned with home lab assignment (e.g., DNA Extraction, PCR, Array, NextGen).
• Meet or exceed workload and performance metric thresholds with accuracy and attention to detail.
• Demonstrate effective time management, task prioritization, and basic troubleshooting skills.
• Perform routine laboratory and equipment maintenance to ensure operational readiness.
• Identify issues that may impact test performance, document corrective actions, and notify appropriate personnel when performance is not at acceptable levels.
• Adhere to quality control policies; document all quality control activities, instrument and procedural calibrations, reagent preparation and testing, and instrument maintenance.
• Ensure proficiency testing is performed in the same manner as patient testing and document accordingly.
• Contribute productively in both independent and team-based work environments.

Education, Experience, and Skills

• Bachelor's degree in medical technology, laboratory science, or in one of the chemistry, or biological sciences and meets CLIA, CAP, and New York State CLEP personnel standards criteria.
• Foundational knowledge as a Lab Technician is preferred but not required.

Physical Demands

• Stand, sit, and use hands frequently
• Occasionally walk, reach, stoop, kneel, crouch, crawl, talk, or hear
• Lift or move up to 10 pounds
• Team members must pass color vision screening; if a deficiency is identified, alternative measures may be required to ensure job performance, and eligibility for roles requiring color vision may be restricted.

Work Environment

Duties are performed onsite with possible exposure to water (hand washing/cleaning), biohazardous fluids, and hazardous chemicals. Employees may experience moderate noise, interruptions, and extended periods of computer work or standing, including reaching, bending, and lifting heavy items. Reasonable accommodations may be provided to enable individuals with disabilities to perform essential functions.

At GeneDx, we create, follow, and are informed by cutting-edge science. With over 20 years of expertise in diagnosing rare disorders and diseases, and pioneering work in the identification of new disease-causing genes, our commitment to genetic disease detection, discovery, and diagnosis is based on sound science and is focused on enhancing patient care.

With hundreds of genetic counselors, MD/PhD scientists, and clinical and molecular genomics specialists on staff, we are the industry's genetic testing experts and proud of it. We share the same goal as healthcare providers, patients, and families: to provide clear, accurate, and meaningful answers we all can trust.

From sequencing to reporting and beyond, our technical and clinical experts are providing guidance every step of the way:

Technical Expertise

• High-quality testing: Our laboratory is CLIA certified and CAP accredited and most of our tests are also New York State approved.
• Advanced detection: By interrogating genes for complex variants, we can identify the underlying causes of conditions that may otherwise be missed.

Clinical Expertise

• Thorough analysis: We classify variants according to our custom adaptation of the most recent guidelines. We then leverage our rich internal database for additional interpretation evidence.
• Customized care: Our experts review all test results and write reports in a clear, concise, and personalized way. We also include information for research studies in specific clinical situations.
• Impactful discovery: Our researchers continue working to find answers even after testing is complete. Through both internal research efforts and global collaborations, we have identified and published hundreds of new disease-gene relationships and developed novel tools for genomic data analysis. These efforts ultimately deliver more diagnostic findings to individuals.

A culture that plays to win, because patients are counting on us

At GeneDx, we're driven by urgency and purpose: helping patients get diagnosed earlier. Our mission, to empower everyone to live their healthiest life through genomics, drives our team to make a tangible impact each day and shapes our culture where high standards, strong teamwork, and meaningful ownership are the norm. We act with intention, support one another, and deliver work we're proud to put our names on.

Here's what you can expect day to day:

1. Play like a champion (step up, redefine what's possible, own it)

We bring energy, focus, and a bias for action. We step up, take initiative, and deliver on our commitments with quality, speed, and care.

2. Think bigger (stretch beyond, courage not consensus)

We push past the obvious. We challenge assumptions, raise the bar, and make thoughtful, decisive calls choosing progress over perfection.

3. Grow fast (be curious, speak up, be agile)

We stay curious, ask questions, and share direct feedback with respect. We adapt quickly and keep learning through collaboration and continuous improvement.

If you're motivated by meaningful work, a fast-moving environment, and teammates who care deeply about outcomes, you'll thrive at GeneDx.
