The Opportunity

Pharmaron is seeking an experienced medicinal chemistry leader to drive the design and delivery of cutting-edge drug discovery programmes, with a particular focus on driving the expansion of our Integrated Drug Discovery (IDD) capabilities into modalities beyond traditional small molecules, such as antibody-drug conjugates (ADCs), oral peptide and oligonucleotide therapeutics.

This is a high impact project facing role, ideal for a scientific leader with a proven track record of advancing molecules through lead optimisation and a passion for innovation beyond traditional small molecules.

The Integrated Drug Discovery (IDD) Services group at Pharmaron is responsible for leading and delivering drug discovery projects for our client partners. The team comprises scientific expertise and strategic leadership across medicinal chemistry, CADD, biology, DMPK and translational science. Combined with Pharmaron's global research capabilities we design and deliver integrated programmes from target identification and hit finding through to IND filing. Working closely with our partners we define strategy, coordinate execution across teams and with an AI enabled accelerated Design-Make-Test-Analyse cycle support the progression of projects and innovative medicines towards the clinic.

This role will build on the substantial capability and track record of Pharmaron's experimental teams in ADC, peptide and oligonucleotide chemistry, and be responsible for the strategic direction and growth of the IDD team's expertise and leadership in new therapeutic modalities.

You will lead end-to-end medicinal chemistry strategy, partnering with global, multidisciplinary teams to deliver high-quality candidates across diverse therapeutic areas. You will also play a key role in expanding integrated drug discovery expertise in modalities beyond traditional small molecules.

Key responsibilities

• Lead and deliver medicinal chemistry strategies from hit identification to candidate selection
• Lead on capability building, delivering project strategy and molecule design for emerging modalities such asantibody-drug conjugates (ADCs), oral peptideand oligonucleotide therapeutics.
• Maintain a high degree of understanding of internal and external developments relevant to the design and optimisation of next generation and emerging modalities
• Drive scientific excellence in compound design, ensuring clear hypotheses and robust data-led decision making
• Provide insightful medicinal chemistry critique across the IDD portfolio
• Work closely with CADD, in vitro biology, in vivo pharmacology and DMPK teams to design and advance compounds across discovery programmes, contributing scientific insight, data interpretation and chemistry leadership
• Provide leadership to global project teams, including close collaboration with China-based experimental teams
• Partner with clients and internal stakeholders to ensure efficient programme delivery
• Communicate programme strategy, progress and outcomes to senior leadership and external partners
• Support business development, proposal development and scientific positioning to strengthen the ADC design capabilities
• Represent Pharmaron at International conferences, client meetings and industry events
• Contribute to IP strategy and patent drafting for client projects.

About you
