The engineer collaborates closely with cross-functional teams to provide technological input, optimize chromatography and other unit operations, and maintain high-quality documentation and communication throughout the product lifecycle.

• Apply general scientific and engineering principles to support the development, scale-up, validation, and transfer of biopharmaceutical manufacturing processes.
• Serve as a key technical contributor in the transfer and continuous improvement of biologics manufacturing processes, with a focus on chromatography operations.
• Collaborate with cross-functional teams to ensure successful clinical and commercial production while maintaining compliance with cGMP and regulatory requirements for US and EU markets.
• Provide technological input and recommendations to improve process robustness, efficiency, and scalability across upstream and downstream unit operations.
• Support the creation, review, and maintenance of technical documentation, including protocols, reports, and standard operating procedures, in accordance with GMP standards.
• Use Microsoft Word and Excel to prepare, analyze, and present process data, reports, and technical summaries.
• Contribute to process analysis activities and, where applicable, apply statistical methods to evaluate process performance and variability.
• Participate in troubleshooting and root cause investigations related to manufacturing processes, proposing and implementing corrective and preventive actions.
• Collaborate effectively with internal stakeholders, including engineering, manufacturing, quality, and regulatory teams, to align process strategies with CMC principles.
• Work independently on assigned technical tasks while also contributing as an active member of cross-functional project teams.
• Support knowledge transfer by sharing technical insights and, when applicable, mentoring junior engineers or technicians in process-related activities.

• Strong documentation skills, with attention to detail and adherence to GMP record-keeping standards.
• Ability to work independently with minimal supervision while effectively contributing to cross-functional teams.
• Familiarity with statistical methods for process analysis, with the ability to apply these tools to assess process performance.

• Experience with upstream processing operations in biologics manufacturing.
• Experience with downstream processing operations, including purification steps such as chromatography.
• Knowledge of Chemistry, Manufacturing, and Controls (CMC) principles and their application to biologics development and manufacturing.
• Experience mentoring or providing guidance to junior engineers or technicians in a technical setting.
• Ability to learn and adapt to new process technologies and equipment used in biopharmaceutical manufacturing.
• Strong collaborative mindset and ability to build effective working relationships across engineering, manufacturing, quality, and regulatory functions.

The role is based in a GMP-regulated biopharmaceutical manufacturing environment that includes ISO-classified cleanroom spaces. The Process Engineer gowns into ISO spaces regularly, typically at least once per week, and follows established cleanroom protocols. This includes removing items such as earrings, cosmetics, and certain hair products prior to entry to maintain contamination control and meet strict environmental standards.
