Johnson & Johnson is recruiting a Summer 2026 intern for the Molecular Measures team within the Precision Measures organization in Neuroscience. As a Molecular Measures intern, you will contribute to the development of novel therapeutics for neurodegenerative and neuropsychiatric diseases by designing and implementing protein measurement assays that inform target engagement, drug efficacy and pharmacodynamics, and patient selection strategies. You will work with multifunctional teams across the drug‑development pipeline, handle human biosamples and state‑of‑the‑art instrumentation, and broaden your skills in protein biochemistry, laboratory‑developed testing, and experimental design in translational medicine.

You will be a part of a team working at the forefront of therapeutic development in the field of neuroscience working to improve patient’s lives.

• Design and implementation of immunoassays (e.g., ELISA, SiMoA, NULISA)
• Evaluation of assay performance and performing statistical analyses
• Troubleshooting of molecular biology assays and related techniques (e.g., BCA, immunoprecipitation)
• Presentations of experimental plans and results at project meetings
• Handling of human biological material in compliance with biosafety regulations
• Commitment to 10–12 weeks of full‑time, on‑site employment (40 hours/week)

• Pursuing a bachelor's degree in neuroscience, biochemistry, molecular biology, or a related discipline, or pursuing an alternative degree with demonstrated interest and relevant laboratory experience
• Strong organizational skills and effective teamwork and communication abilities
• Creative problem‑solving and adaptability
• Curiosity about protein biology in neurological disease
• Preferred: familiarity with biosafety procedures and common molecular biology techniques (pipetting, solution preparation, introductory statistics)
• Preferred: completion of introductory biology and chemistry coursework and entering sophomore year or above in Fall 2026
• Applicants must be permanently authorized to work in the U.S. and must not require employer sponsorship now or in the future (e.g., H‑1B or green card sponsorship). Students currently on CPT, OPT, or STEM OPT usually require future sponsorship for long‑term employment and therefore do not meet this requirement unless they are eligible for an alternative long‑term status that does not require company sponsorship.

The expected pay range for this position is between $26.50 per hour and $59.00 per hour, based on candidate's program year, discipline, degree and/or experience.
