What does a pharmaceutical process engineer do?

A pharmaceutical process engineer reviews the requirement to produce a pharmaceutical product and develops a process for manufacturing. In this career, your duties vary from employer to employer but usually include tasks such as providing technical specifications for machinery and equipment, working to estimate costs for production, and undertaking a negotiation for the procurement of necessary materials and ingredients. Your responsibilities as a process engineer may include providing analysis of the process to ensure efficiency, safety, and compliance with relevant regulations.

What does a pharmaceutical process engineer do?

A Pharmaceutical Process Engineer is responsible for designing, developing, and optimizing processes used in the manufacturing of pharmaceutical products. They ensure that production methods are efficient, safe, and compliant with regulatory standards. Their work involves troubleshooting process problems, implementing new technologies, and collaborating with other departments to improve product quality and production efficiency. They play a critical role in scaling up laboratory processes to full-scale manufacturing while maintaining product integrity and safety.

What are some common challenges faced by pharmaceutical process engineers when scaling up production from laboratory to manufacturing scale?

Pharmaceutical Process Engineers often encounter challenges when translating lab-scale processes to full-scale manufacturing, such as maintaining product quality, ensuring process consistency, and meeting strict regulatory requirements. Controlling variables like temperature, pressure, and mixing at a larger scale can introduce unforeseen issues that require innovative problem-solving. Collaboration with cross-functional teams—including quality assurance, validation, and production staff—is essential to address these challenges efficiently. Adaptability and attention to detail are crucial in ensuring a smooth and compliant scale-up process.

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

To thrive as a Pharmaceutical Process Engineer, you need a strong background in chemical or process engineering, pharmaceutical manufacturing, and regulatory compliance, typically supported by a relevant engineering degree. Familiarity with process simulation software (such as Aspen Plus), GMP standards, and quality management systems is essential. Attention to detail, problem-solving skills, and effective teamwork are crucial soft skills for optimizing processes and ensuring product quality. These competencies are vital for developing efficient, safe, and compliant pharmaceutical manufacturing processes that meet industry standards.

What is the difference between Pharmaceutical Process Engineer vs Pharmaceutical Manufacturing Technician?

AspectPharmaceutical Process EngineerPharmaceutical Manufacturing Technician
Required CredentialsBachelor's degree in engineering, chemistry, or related field; often includes certifications in process validationHigh school diploma or associate degree; on-the-job training or technical certifications
Work EnvironmentDesign, optimize, and oversee manufacturing processes in labs or production facilitiesOperate equipment, monitor production lines, and ensure quality in manufacturing settings
Employer & Industry UsagePharmaceutical companies, biotech firms, contract manufacturing organizationsPharmaceutical manufacturing plants, biotech production facilities

The main difference is that Pharmaceutical Process Engineers focus on designing and improving manufacturing processes, requiring higher technical credentials, while Pharmaceutical Manufacturing Technicians handle day-to-day production tasks and equipment operation. Both roles are essential in pharmaceutical production but differ in responsibilities and qualifications.

Job description

PsiQuantum's mission is to build the first useful quantum computers-machines capable of delivering the breakthroughs the field has long promised. Since our founding in 2016, our singular focus has been to build and deploy million-qubit, fault-tolerant quantum systems.
Quantum computers harness the laws of quantum mechanics to solve problems that even the most advanced supercomputers or AI systems will never reach. Their impact will span energy, pharmaceuticals, finance, agriculture, transportation, materials, and other foundational industries.
Our architecture and approach is based on silicon photonics. By leveraging the advanced semiconductor manufacturing industry-including partners like GlobalFoundries-we use the same high-volume processes that already produce billions of chips for telecom and consumer electronics. Photonics offers natural advantages for scale: photons don't feel heat, are immune to electromagnetic interference, and integrate with existing cryogenic cooling and standard fiber-optic infrastructure.
In 2024, PsiQuantum announced government-funded projects to support the build-out of our first utility-scale quantum computers in Brisbane, Australia, and Chicago, Illinois. These initiatives reflect a growing recognition that quantum computing will be strategically and economically defining-and that now is the time to scale.
PsiQuantum also develops the algorithms and software needed to make these systems commercially valuable. Our application, software, and industry teams work directly with leading Fortune 500 companies-including Lockheed Martin, Mercedes-Benz, Boehringer Ingelheim, and Mitsubishi Chemical-to prepare quantum solutions for real-world impact.
Quantum computing is not an extension of classical computing. It represents a fundamental shift-and a path to mastering challenges that cannot be solved any other way. The potential is enormous, and we have a clear path to make it real.
Come join us.
Job Summary:
The Senior Optical Process Engineer will be responsible for process development and assembly build with quality for R&D and volume system integration and deployment at PsiQuantum. This role requires engineering disciplines in packaging, processing, and associated qualifications, a strong "can-do" attitude in a fast-paced environment, problem-solving, and excellent communication with teams across multiple disciplines
Responsibilities:
  • By working with the sub-assembly design and packaging engineering team, develop assembly process flows and build sub-assemblies for quantum computer (QC) subsystems with electronics and silicon photonics chips on PCBAs for both cryogenic and room-temperature vacuum systems.
  • By working with a cross-functional team and suppliers, finalize the design and assembly process flow using DFM, DFQ, and FMEA tools to meet design targets and requirements set by the sub-system team.
  • Deliver and verify equipment, tooling, and fixtures from suppliers with the support of the supply chain. Complete process development and buy-off, including process capability analysis and a report.
