Medical Communications Scientist jobs

Principal Clinical Scientist

(Senior Clinical Scientist level also considered)

The Role

We're looking for a clinical scientist — someone who has been the scientific lead for clinical studies before, from protocol development to start-up (development of critical study documents) through to study execution, data analysis and interpretation and close-out with a clinical study report. Having prepared regulatory submissions of study results is a pre. You'll work in close partnership with the clinical operations team and CROs under the team's full-outsource operating model, managing that day-to-day relationship rather than delivering trial activity in-house. It's one of two newly approved roles, created ahead of anticipated demand rather than to backfill a departure, which means there's genuine room to help shape how the team works rather than simply joining an existing structure.

Hybrid based (3 days a week onsite) in Maidenhead (UK), Melbourne (Aus) or Zurich (CH)

Why It Matters

A clinical study is only as good as the people running it. A weak protocol, poorly managed start-up, or a fumbled relationship with the CRO delivering the trial can cost a program months — sometimes far more — and that delay sits between a therapy and the patients waiting on it. This role exists because CSL is adding capacity to get that execution right: someone who can lead all scientific needs of a study properly, and co-own the end to end alongside clinical operations, is what actually moves a clinical development plan forward. It's not a supporting or administrative function — it's the core that determines whether the science translates into a trial that runs cleanly and data that holds up.

What You'll Be Responsible For

You'll take ownership of clinical studies end-to-end, acting as the scientific and operational anchor between the program team and outsourced delivery partners.

• Lead all scientific elements of clinical studies from protocol development through study execution to a final clinical study report
• Write and/or take responsibility for study protocols, clinical study reports and other critical study documents
• Manage, alongside the clinical operations lead, day-to-day working relationships with CROs under a full-outsource operating model
• Collaborate closely with the cross-functional study teams — this is a collaborative role, not an isolated one one
• Contribute to the scientific interpretation of clinical data and supporting documentation
• Build working relationships across the wider team, including colleagues based in the US and Australia

Experience Required

• Demonstrated, hands-on experience with clinical studies (protocol development, execution, close-out) — not solely oversight or academic exposure
• Experience writing clinical study protocols and clinical study reports directly
• Experience working within a full-outsource / CRO-dependent operating model
• A collaborative, cross-functional working style — comfortable building relationships rather than working independently
