Manager, Transactional Finance

Company introduction

Compass Pathways plc (Nasdaq: CMPS) is a biotechnology company dedicated to accelerating patient access to evidence-based innovation in mental health. The Company is headquartered in London, UK, with offices in New York City in the US. We focus on developing novel treatments that have the potential to improve the lives of those who are suffering with mental health conditions and who are not helped by current treatments.

We are pioneering a new paradigm for treating mental health conditions focused on rapid and durable responses through the development of our investigational COMP
360 synthetic psilocybin treatment, potentially a first in class treatment. COMP
360 has Breakthrough Therapy designation from the US Food and Drug Administration (FDA) and has received Innovative Licensing and Access Pathway (ILAP) designation in the UK for treatment‑resistant depression (TRD) due to the pressing unmet need in this area.

We are currently in phase 3 for TRD, have completed phase 2 studies for both post‑traumatic stress disorder (PTSD) and anorexia nervosa and are planning a further late‑stage study in PTSD. We envision a world where mental health means not just the absence of illness but the ability to thrive.

The Manager, Transactional Finance will lead the day‑to‑day management, optimization, and control of Accounts Payable (AP) and Accounts Receivable (AR) activities across Compass Pathways' UK and US operations.

This role plays a key part in ensuring accurate, timely, and compliant transaction processing, while supporting strong working capital discipline and scalable finance operations in a growing international biotech company.

Working closely with the wider Finance team and cross‑functional stakeholders, you will combine hands‑on operational ownership with process improvement, controls, and team development in line with Compass' culture and values.
