Manufacturing Test Development Engineer


JUUL was founded by former smokers, James and Adam, with the goal of improving the lives of one billion adult smokers. We envision a world where fewer people use cigarettes, and where people who smoke cigarettes have the tools to reduce or eliminate their consumption entirely, should they so desire.

JUUL's mission is to improve the lives of the world’s one billion adult smokers by driving innovation to eliminate cigarettes. JUUL is the number one US-based independent vapor product. Headquartered in San Francisco and backed by leading technology investors including Tiger Global, Fidelity Investments and Tao Invest LLC, JUUL Labs is disrupting one of the world’s largest and oldest industries.

We’re an exceptional team with backgrounds in technology, healthcare, CPG and biotech, and we’re growing rapidly to deliver on our mission. We’re actively looking to hire the world’s best scientists, engineers, designers, product managers, supply chain experts, customer service and business professionals.
