• Drive Innovation: Identify and lead process and equipment improvements, from concept through to funding and implementation.
• Collaborate Cross-Functionally: Work closely with Operations, MSAT, Quality, Engineering, and Technical Services to ensure seamless execution and continuous improvement.
• Project Leadership: Manage short-duration technical projects, ensuring delivery on scope, cost, and schedule while navigating technical challenges.
• Champion Excellence: Promote a culture of Right-First-Time and Zero Defects, and contribute to audit readiness and defence as a technical expert.
• Mentor and Influence: Coach peers and junior colleagues, sharing best practices and fostering a culture of learning and collaboration.

What You Bring

• A degree in Science or Engineering (Chemical/Biological focus preferred); equivalent experience considered.
• 5+ years of cGMP experience in biopharma manufacturing, technical operations, or engineering.
• Strong working knowledge of upstream cell culture and downstream purification.
• Proficiency with digital tools such as eQMS (Veeva Vault/QTS), MCS, PI, LIMS, and AMPS.
• Demonstrated ability to work independently, lead investigations, and influence cross-functional teams.
• Method One certification and experience with process monitoring systems and automated control systems.
• Excellent communication, problem-solving, and stakeholder engagement skills.

What Sets You Apart

• You're not just technically strong - you're a strategic thinker who sees the bigger picture.
• You're proactive, solutions-focused, and thrive on driving improvements that matter.
• You're a natural collaborator who builds trust and delivers results across functions and levels.
