6 min read

From the first mass‑produced sterile surgical dressings in the 1880s to first‑in‑class CAR‑T cell therapies in the 2020s, Johnson & Johnson (J&J) has continuously re‑invented healthcare. Following the 2024 spin‑off of its consumer division (Kenvue) and the rebrand of Janssen to Johnson & Johnson Innovative Medicine, the company now focuses squarely on pharmaceutical innovation, med‑tech and vision care. With revenues exceeding US $90 bn and a pipeline spanning oncology, immunology, vaccines and digital surgery, J&J remains a magnet for biotech talent.

A quick scan of the Johnson & Johnson careers portal shows over 2,000 open roles in EMEA, with nearly 300 in the UK, across R&D, manufacturing, clinical affairs and data science. This guide explains how to land a Johnson & Johnson biotech job in 2025—from graduate scientist to principal data engineer.
