If you’re passionate about changing lives for the better, this is the opportunity you’ve been waiting for. In Research & Development, we’re continuously exploring innovative new treatment options to make a stronger, more positive impact on the lives of the patients we serve. You’ll work with talented colleagues in a state-of-the-art Research & Development environment, developing innovative medicines that change the life of patients for the better and help us make progress towards our vision of a world free of pain. Join us today, and discover the difference you can make.
What The Job Looks Like
Every day you will enjoy different challenges such as:
- Lead the design and computational optimisation of RNA therapeutics, particularly siRNA, integrating RNA biology with oligonucleotide chemistry to enable gene knockdown and RNA regulatory approaches, including up-regulation strategies.
- Define and prioritise target sites and design strategies by integrating sequence features, RNA accessibility, transcript structure, cross-species alignment, and emerging experimental data
- Drive iterative design–test–learn cycles by analysing and rapidly integrating datasets linking sequence, chemistry, and biological activity to inform decision-making
- Develop and apply computational tools and workflows (e.g. Python or R) to enable scalable oligonucleotide design, data integration, and rapid sequence–chemistry iteration
- Partner closely with oligonucleotide chemists and delivery scientists to co-optimise sequence, chemical modifications, and delivery approaches to maximise potency, durability, and tissue activity
- Lead and contribute to discovery programs advancing RNA therapeutic candidates toward candidate profiling and clinical development, while helping prioritise and evaluate new targets aligned with platform capabilities.
Reasons to use Rodeo
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.
It searches the market for you
Every day your agent scans the market matching roles against what actually matters to you, not just keywords on a CV.
Only hits
No noise. No "maybe this fits." Just roles with a clear explanation of why they're right — and where to focus when applying.
What You'll Bring To The Table
To make the most of this role and truly thrive, you should have:
- PhD in RNA biology, molecular biology, computational biology, bioinformatics, or a related discipline
- More than 10 years of relevant industry experience, including at least 5 years in therapeutic antisense or siRNA design and optimisation
- Strong computational skills, including experience developing scripts or workflows (e.g. Python or R)
- Experience designing siRNA across CNS and systemic delivery contexts, including optimisation of sequence and chemistry for robust in vivo activity
- Proven track record contributing to or leading programs that progressed molecules to candidate stage, with demonstrated involvement in programs advancing toward clinical development
- Strong understanding of oligonucleotide optimisation and risk assessment across discovery and development stages, from early design through to late-stage candidate selection
- Experience delivering siRNA therapeutics in liver and CNS indications is highly desirable, ideally including progression of molecules toward clinical development
- Strong scientific problem-solving mindset with a focus on delivering impact
- Ability to operate effectively in a highly matrixed, cross-functional environment with a high degree of independence, ownership, and accountability
