Stable Company, Good Learning in Biotech Manufacturing
Pros: I appreciate the stability working here at Lonza, especially in the biotech industry. There's a strong sense of job security, which is important for long-term career planning. I've had many opportunities to learn new processes and develop my skills, thanks to supportive colleagues and readily available training. It's a great place if you're looking to build a career in manufacturing operations within life sciences.
Cons: One area that could improve is the pace of career progression; promotions sometimes feel a bit slow given the company's size. Also, like any manufacturing role, there are occasional busy periods and project deadlines that can make work-life balance a bit tricky, but it's usually manageable. The internal approval processes can sometimes be a bit bureaucratic.
Advice to Management: Focus on streamlining internal processes to improve efficiency and actively identify opportunities for faster career progression for dedicated employees.

Good Place for Biopharma Process Engineers, Flexible
Pros: As a Process Engineer at Lonza's Portsmouth, NH site, I appreciate the learning opportunities in biopharmaceutical manufacturing. Colleagues are supportive, and I've found good work-life balance with decent flexibility, which is key. It's a stable environment for a CDMO company.
Cons: Career progression can feel slow for a Process Engineer here, requiring patience. Also, inter-departmental communication could be improved across this large CDMO.
Advice to Management: Focus on streamlining internal communication channels to improve cross-departmental project execution and clarify career pathing for technical roles.

Great Place for Biotech Professionals
Pros: The company culture here at Lonza, especially in Portsmouth, is genuinely supportive. My colleagues in Process Engineering were always willing to help, which made learning new biotech processes much smoother. There are good internal training programs for career development in the pharmaceutical manufacturing industry. It's a stable, large company.
Cons: Sometimes, the approval processes for new initiatives can feel a bit slow. This is pretty typical for a large pharmaceutical manufacturing company, but it can be frustrating. While career progression is there, it can feel a bit slower than in a fast-paced startup. Also, project deadlines definitely lead to busy periods.
Advice to Management: Streamline some of the internal approval processes to encourage faster innovation and project execution within the manufacturing sites.

Solid Biopharma Opportunity with Great Team Support
Pros: Lonza offers a great team environment, crucial for a lab-based Associate Scientist in biopharma manufacturing. Colleagues are supportive, making tasks smoother. There are solid learning opportunities to expand technical skills, and I appreciate the strong focus on quality in the CDMO space.
Cons: The internal promotion process feels a bit slow, so career progression can take longer. Also, inter-departmental communication could be more consistent for better efficiency. These are minor points in an otherwise positive experience.

Decent flexibility for biotech manufacturing roles
Pros: As a Process Development Scientist, I could often manage my own schedule. There's a solid hybrid model available for some roles, which helped with personal appointments. This really improved my work-life balance and navigating traffic in Portsmouth, NH.
Cons: Not all departments offer the same flexibility. If you're in a cGMP environment or working with drug substance production, you're pretty much onsite full-time. It's tough for those biotech manufacturing roles to get true remote work options.
Advice to Management: Try to standardize flexibility policies across all non-cGMP departments. Recognize that even onsite teams can benefit from occasional WFH days or flexible hours to boost morale and retention for key roles.

Lonza Culture - A Mixed Bag for Scientists
Pros: As a Research Associate, I've gained solid experience in biopharmaceutical manufacturing. Many colleagues are great to work with, and there's good camaraderie within the lab teams here in Portsmouth, NH. The work itself can be quite engaging.
Cons: The overall company culture sometimes feels like it's lacking direction. Communication from upper management often misses the mark, making strategic shifts confusing. It can be tough to feel truly connected as an onsite employee to the broader corporate goals.
Advice to Management: Focus on improving internal communication across departments and sites. Clearly define and reinforce the company's cultural values for all employees. It would really help bridge the gap between corporate decisions and day-to-day operations for us in scientific roles.

Work-Life Balance is Okay, Not Great
Pros: I've mostly had decent experiences with my team for day-to-day operations. The shift schedule for many onsite roles can be predictable once you're used to it, which helps plan personal life a bit. There's good health insurance, which is a solid benefit.
Cons: Sometimes the workload for drug manufacturing is just intense, and overtime is basically mandatory. It's tough to have a consistent work-life balance when production schedules are constantly changing or you're short-staffed. You really feel the pressure during peak periods, and managers expect you to step up.
Advice to Management: Try to staff teams better so we're not constantly doing mandatory overtime. Recognize the effort employees put in when production ramps up.

Decent place, but work-life balance is tough.
Pros: As a Research Scientist, I got to work on some really cutting-edge projects. The company culture is generally supportive among team members, and the facilities in Basel are pretty modern.
Cons: Work-life balance here isn't great, especially for R&D roles. You often end up working 50+ hour weeks, and there's pressure to be available even after hours. Don't expect much flexibility for personal appointments.
Advice to Management: Try to enforce more reasonable working hours for Research Scientist teams. A better hybrid work policy would also make a huge difference.

Decent pay, but culture felt disconnected.
