Solid place for manufacturing engineers in photonics
Pros: I've really enjoyed my time as a Process Engineer here. It's a stable company within the photonics and laser industry, and I've had great opportunities to work with cutting-edge manufacturing technology. My colleagues are super supportive and collaborative, and there's a good learning environment on campus. The compensation and benefits package is competitive too, which is always a plus for an engineer.
Cons: While there's a lot to like, internal communication could be better sometimes, especially between different departments and across facilities. Also, the approval processes for new projects can feel a bit slow, which can be frustrating when you're trying to move fast. Career progression for individual contributor roles feels a bit less structured than it could be.
Advice to Management: Focus on streamlining internal communication channels and clarifying career progression paths for individual contributors to help them better understand their growth opportunities within the company.

Decent Pay, but Benefits Need Work Here
Pros: As a Process Engineer, the base salary was pretty competitive for the semiconductor industry in the Saxonburg, PA office. They also offer a solid 401k match, which is definitely a plus in this corporate environment.
Cons: The health insurance plans aren't great; the deductibles are really high, making it tough to use. Don't expect huge annual raises unless you get promoted.
Advice to Management: Please look into better health insurance options for employees. Improved benefits would significantly boost morale and retention.

Leadership Needs to Step Up at Coherent
Pros: The technical challenges are actually pretty solid here. As a Process Engineer, I've learned a ton in semiconductor manufacturing, which is a big plus for my career. My immediate team in the Santa Clara, CA office is also really supportive.
Cons: Leadership above the direct manager level feels pretty disconnected from the daily grind. They don't seem to really listen to the folks on the ground, especially regarding production issues. Communication from the top is often confusing and decisions can feel arbitrary.
Advice to Management: Listen more to your frontline engineers and technicians. Improve communication channels and make sure decisions are clearly explained and well-reasoned. Invest in leadership training for middle and senior management.

Flexibility is okay, but it depends
Pros: Some managers in the Santa Clara, CA office are pretty good about WFH if your tasks allow it. You can usually arrange a decent hybrid model if you're not in a critical manufacturing environment. It's a stable company for engineers.
Cons: As a Process Engineer, I found that on-site expectations are high, especially for those supporting production. It's tough to get consistent work flexibility when you need lab access daily. Most engineering roles aren't really set up for remote work.
Advice to Management: Look at which roles truly need daily on-site presence. More remote or hybrid options could really help retention, especially for design or non-fab-floor engineering teams.

Cons: Job security can feel a bit up in the air sometimes, especially after the recent mergers. It's an established company, but the larger corporate changes make you wonder. Career growth isn't always clear for individual contributors.
Advice to Management: Try to be more transparent about the long-term plans for roles, especially after big corporate changes. Clearly lay out paths for career growth for individual contributors.
