Process Development Scientist
3.3
11 April 2026
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.

Okay for entry-level, career growth is slow
Pros: You learn a lot about sterile drug product manufacturing processes early on. The initial training for an onsite role at the Portsmouth, NH office is pretty solid. It's a stable company, which is a plus for job security.
Cons: Career growth for technical roles like Process Engineer feels really limited. It's hard to move up, and there aren't many opportunities for internal transfers. Promotions are very slow and often depend more on who you know than your performance.
Advice to Management: Create more transparent career paths for engineers and technical staff. Invest in internal development programs and make promotions merit-based, not just tenure-based. This would really help retention.

Pay's okay, but could be better for the industry.
Pros: The health insurance is pretty good, honestly. Benefits package is decent, especially for vision and dental. Plus, there's a 401k match, which is always a bonus.
Cons: The base pay for Manufacturing Associate roles at the Portsmouth, NH site just isn't competitive. You feel pretty underpaid for the amount of work and specialized knowledge needed in biotech manufacturing. Raises are small, often less than inflation.
Advice to Management: Seriously review the salary bands for entry to mid-level positions, especially for Manufacturing Associates. We're losing good people to competitors who offer much better compensation in the pharmaceutical industry. Invest more in fair pay.

Benefits are good, but base pay could be better
Pros: The health insurance is pretty good, and the 401k match is decent for a big pharma company. We also got a pretty consistent annual bonus, which helped make up for the base pay a bit. It's a solid benefits package for Manufacturing Associate roles.
Cons: My base salary as a Manufacturing Associate felt pretty low for the Portsmouth, NH area, especially considering the cost of living. There's not much wiggle room for salary negotiations, even with experience in biomanufacturing. It's tough to feel valued when pay isn't great.
Advice to Management: You really need to re-evaluate the base salaries for entry-level and mid-level biomanufacturing roles. Matching industry standards would help retain good talent, especially in competitive markets like Portsmouth, NH.

Work-Life Balance is a Real Challenge Here
Pros: You get solid pay and benefits for this type of onsite manufacturing work, which is a big plus in the pharmaceutical industry. The job security feels good, and your immediate team often has your back during tough shifts. It's a stable company overall.
Cons: The biggest struggle is the work-life balance, especially with mandatory overtime and 12-hour shifts. As a Manufacturing Associate, you often work unexpected evenings or weekends, which makes it super hard to plan anything outside of work. You can feel pretty drained.
Advice to Management: Try to staff more adequately to reduce the reliance on mandatory overtime for Manufacturing Associates. Giving more predictability in schedules would really help with employee morale and retention in these critical onsite roles.
