Summary

Your new company
You'll be joining a global biopharmaceutical organisation recognised for its deep scientific expertise and commitment to developing transformative therapies for patients with immune‑mediated inflammatory diseases.The in vivo pharmacology team plays a central role in advancing discovery programmes, working in a collaborative, science‑driven environment where curiosity, rigour and teamwork are highly valued. This is an opportunity to contribute directly to early‑stage research while developing your skills alongside experienced in vivo scientists and multidisciplinary project teams.


Your new role
This is initially a 12-month contract role, working in a tight-knit and experienced team, where you'll be integral to the company's in-vivo programmes primarily within their immunology portfolio.
Responsibilities will include:

• Design, plan and execute in vivo studies supporting target identification, validation and translational pharmacology.
• Apply strong hands‑on expertise in in vivo immunology models, ensuring appropriate model selection and scientific robustness.
• Generate, analyse and interpret high‑quality in vivo data aligned with project timelines and decision points.
• Support the establishment, optimisation and validation of in vivo models, including oversight of outsourced studies with CRO partners.
• Contribute scientific insight to project teams through data review, interpretation and critical evaluation.
• Ensure all studies are conducted in compliance with regulatory, ethical and animal welfare requirements.
• Collaborate effectively with colleagues across disciplines to support discovery and early development objectives.
• Maintain accurate documentation and contribute to study summaries, reports and presentations.

All candidates must have the full right to work in the UK until at least March 2027 - no visa sponsorship is available.

What you'll need to succeed

• An MSc (PhD preferred) in Pharmacology, Immunology, Biochemistry, Biology or a related discipline (or equivalent experience), with relevant postdoctoral or industry experience.
• Holder of a Home Office Project Licence (or eligibility to obtain one).
• Strong hands‑on experience with in-vivo pharmacology and immunology models relevant to inflammatory and immune‑mediated diseases, preferably within a pharmaceutical, biotech or CRO environment, though people with academic experience as a post-doc will be considered.
• Demonstrated ability to design robust in-vivo experiments and interpret complex datasets.
• A pragmatic, delivery‑focused mindset with strong attention to scientific rigour and data quality.
• Ability to work independently while contributing effectively within multidisciplinary project teams.
• Experience with in-vivo cell depletion models would be an advantage but is not required.

What you'll get in return
You'll have the chance to make a real impact on the company's preclinical development programmes, working in a high-performing and well-experienced team, as well as gaining significant exposure internally. You'll also receive a good hourly/daily rate.
