What does a chemical process engineer do?

A Chemical Process Engineer is responsible for designing, developing, and optimizing processes used in the production of chemicals, fuels, pharmaceuticals, food, and other products. They work to improve efficiency, safety, and sustainability in manufacturing plants by analyzing chemical reactions, equipment, and workflows. Chemical Process Engineers often collaborate with other engineers and technicians to troubleshoot problems and implement new technologies in production systems.

What is the difference between Chemical Process Engineer vs Chemical Production Technician?

AspectChemical Process EngineerChemical Production Technician
CredentialsBachelor's degree in chemical engineering or related fieldAssociate's degree or technical certification in chemical technology
Work EnvironmentDesign, optimize, and oversee chemical processes in labs or plantsOperate and maintain equipment on the production floor
Employer & Industry UsageManufacturing, petrochemical, pharmaceuticals, and energy sectorsChemical manufacturing plants and processing facilities

The Chemical Process Engineer focuses on designing and improving chemical processes, requiring a degree in engineering. In contrast, the Chemical Production Technician handles daily operations and equipment maintenance, often with technical certifications. Both roles are vital in chemical industries but differ in responsibilities, education, and work scope.

What is a chemical process engineer?

A chemical process engineer’s responsibilities cover designing and developing processes for transforming raw materials into marketable products. You can hold a chemical process engineer job in an industry that processes natural gases, paper, pharmaceuticals, plastic, food, and other products. You will analyze procedures, communicate effectively with team members, apply math, science, and engineering concepts, and conduct experiments and report the results. Many types of chemical engineering careers exist in chemical production and manufacturing, mineral processing, oil exploration, sustainable engineering, and alternative energy fields. However, you can find chemical engineers with diverse duties in jobs in nearly every industry that creates a product.

What are the key skills and qualifications needed to thrive as a chemical process engineer, and why are they important?

To thrive as a Chemical Process Engineer, you need a solid background in chemical engineering principles, process design, and safety regulations, typically supported by a bachelor's degree in chemical engineering or a related field. Familiarity with process simulation software (such as Aspen Plus or HYSYS), knowledge of P&ID development, and relevant certifications like Six Sigma are highly valuable. Strong analytical thinking, problem-solving skills, and effective teamwork and communication abilities help you excel in this role. These skills ensure that processes are efficient, safe, and cost-effective, supporting both operational excellence and regulatory compliance.

What are some typical challenges a chemical process engineer faces when optimizing plant operations?

Job description

Description
Who We Are
BioMarin is a leading rare disease biotechnology company focused on genetically defined conditions.
Guided by our purpose to develop medicines that make a profound impact on people's lives, our global teams have delivered a portfolio of therapies since our founding in 1997. Our revolutionary treatments for conditions like achondroplasia (the most common form of dwarfism), PKU (phenylketonuria), CLN2, a form of Batten disease, and a number of forms of MPS (mucopolysaccharidosis) offer new possibilities for patients and families who previously had few, if any, available options. More recently, with the close of the Amicus acquisition, our portfolio has expanded to include therapies for Fabry disease and Pompe disease, expanding our ability to reach more people living with rare genetic conditions.
Our success comes from our unwavering commitment to excellence, our deep understanding of patient needs, our scientific expertise, and our world-class manufacturing capabilities. At the heart of BioMarin is a dedicated team of the brightest minds in the industry working together to deliver innovative therapies to patients and families around the world.
About Technical Operations
BioMarin's Technical Operations group is responsible for creating our drugs for use in clinical trials and for scaling production of those drugs for the commercial market. These engineers, technicians, scientists and support staff build and maintain BioMarin's cutting-edge manufacturing processes and sites, provide quality assurance and quality control to ensure we meet regulatory standards, and procure the needed goods and services to support manufacturing and coordinating the worldwide movement of our drugs to patients.
Senior Scientist 2, Chemical Development & Manufacturing
This exciting role has emerged due to growth in the Chemical Development & Manufacturing group, which is part of the Drug Substance Technologies (DST) function in the Technical Development & Services (TDS) organisation. Our pipeline consistently features new and diverse programs, which require development and manufacturing leadership throughout the full product lifecycle.
The Chemical Development & Manufacturing group leads the CMC development for all synthetic chemistry programs across Technical Operations (TOPS); while the diversity of modalities are continuing to grow, small molecules, oligonucleotides, peptides and PEGs are firmly established. A wonderful opportunity for a team player, with appropriate scientific skills and experience, as well as an energetic, growth mindset, to join an established, high functioning team.
The role involves driving clinical programs, through PPQ, as a Partner Team Lead (PTL).
Cross functional collaboration behaviors are critical to the role, where connectivity forms a mainstay of day to day activity. Interfacing groups include other Drug Substance modality functions, sister groups in TDS, including Formulation and Analytical departments.
Broader interfacing groups in the wider TOPs organization are also in play, especially External Manufacturing, Quality and Supply Chain, as well as enterprise-wide synergies with Research, Regulatory Affairs, Finance, Legal and others.
Project management, especially with regard to active programs with Contract Manufacturing and Development Organizations (CDMOs), will draw upon excellent written and communication skills, as well as strong leadership behaviors. Contribute to the group strategy, participating in budget preparation and monitoring, as well as program planning.
Leadership Responsibility:
Through cross functional team engagement, collaboratively working on the technical team, ultimately to meet Enterprise-wide program timelines, including:
  • Identify and assist in selection of new CDMOs, building a deep knowledge of the external landscape.
  • Together with the DS team, drive the strategy and performance of the CDMO network, as well as the internal functions, to deliver enterprise and group goals.
  • Anticipate scientific, business and program challenges, while working cross functionally to solve problems.
  • Manage drafting and delivery of 3.2.S filing sections and address HA questions, in appropriate sections.
  • Periodic in person visits to other BioMarin and CDMO locations, to ensure continued connectivity and alignment, across the internal network and Person-in-plant support, respectively.
  • Play a part at the forefront of internal synthetic chemistry innovation, to ensure new technologies are identified, evaluated and implemented, positioning TDS centrally for cutting edge initiatives and early adaptation. Share learnings at appropriate platforms.

Must have: Minimum Requirements:
  • Bachelors, Masters or PhD level in Chemistry or Chemical Engineering. Post-doctoral experience would be an advantage, while business, leadership or related training credentials, would be desirable.
  • A combined minimum of 9 years of related experience is required in synthetic molecule, drug substance development environments and CMC DS program management.
  • Working knowledge of pharmaceutical regulatory requirements, as well as solid cGMP skills.
  • Excellent written and oral communication skills; expectation to present frequently, at in- house forums.
  • Demonstrated capability at handling multiple programs and projects, at the one time.
  • Agreement to work in a hybrid fashion, spending 2 days per week, on average, at the local BioMarin site.
  • Travel: 20% - 30%.

Nice to have:
  • Experience in Oligonucleotide development and/or manufacture, would be an advantage.
  • Familiarity and/or working with ERP and quality documentation systems are desirable but not required.
