About the Role
Working with the existing members of the Chemistry Department and various UK and overseas Contract Research Organizations (CROs), the successful applicant will support medicinal chemistry projects and coordinate synthetic chemistry activities to ensure the delivery of high-quality small molecule development candidates within competitive timeframes, while safeguarding the Company’s intellectual property by advancing its patent estate. This is a remote, desk-based role and does not involve wet work. May include occasional F2F meetings in the London to Cambridge corridor.
Main Responsibilities
- Efficient support of management of remote teams of medicinal and synthetic chemists at CROs.
- Integrate and analyse project biology and DMPK data to enable successful hit-to-lead and lead optimisation campaigns through rational molecular design.
- Timely upload of project data to company database and recording in ELN.
- Support patent filings with experimental write up and data checking.
- Work collaboratively within the Company’s project teams, with colleagues in biology, biophysics and computational sciences and with external collaborators such that objectives are met in a timely manner.
- Communicate effectively, interpret and summarize complex data for presentation to different audiences.
- Prioritise work according to project goals and take responsibility for the timely delivery of objectives.
- Keep up to date with state-of-the-art technologies and knowledge of developments in medicinal chemistry.
Reasons to use Rodeo
I’m in my final year doing Economics and I don’t know whether to apply for grad schemes now or do a masters first. What do you think?
Honest answer — it depends on where you want to end up. A lot of top grad schemes (Big 4, civil service, banking) don’t need a masters. Let’s look at the ones you’d be competitive for now, and we can decide if a masters actually adds anything.
Also worth knowing: most autumn 2026 applications are open now. Timing matters more than you think.
Start with a chat, not a search bar
Grad scheme, placement, apprenticeship? Not sure what you want yet — that's fine. Your agent talks it through with you and turns "I have no idea" into a shortlist.
