Software Engineer

Great Place for Learning and Tech Development
Pros: I've really enjoyed my time here as a Software Engineer. The learning opportunities are fantastic; I've picked up so many new skills and technologies. Colleagues are super supportive and always willing to help out. It's a stable environment, which I appreciate in the tech industry. Plus, the work flexibility is great for my personal life.
Cons: While career growth is good, the promotion process can sometimes feel a bit slow. There are also occasional busy periods where work-life balance can get a bit stretched. Communication from upper management could be a little more consistent on strategic decisions too, but it's not a major issue.
Advice to Management: Keep investing in clear communication channels for company-wide updates and consider streamlining the promotion pathways for high-performing employees.

Leadership is a real mixed bag here
Pros: Some direct managers are solid, especially for remote Senior Software Engineer roles. You can find good people to work with who genuinely care about the project and team. The technical challenges in aerospace tech are often pretty engaging.
Cons: Upper management often feels out of touch. They make big decisions without getting input from the teams actually doing the work. This makes project planning chaotic and deadlines can shift constantly for the engineering department.
Advice to Management: Listen to your technical teams more often, especially when setting project timelines. More transparency from top leadership would really help morale and improve project execution across all engineering functions.

Decent pay for a growing aerospace tech company
Pros: The health insurance benefits are solid, that's a big plus. They also have a decent 401k match, which isn't always a given at a mid-sized tech company. It's good for the aerospace tech industry.
Cons: Base salary for Software Engineer roles in Pasadena, CA feels just okay. I've seen better total compensation packages at similar companies. PTO accrual isn't super generous either, which is a bummer.
Advice to Management: Review the base salaries for engineering roles, especially considering the cost of living in Pasadena, CA. More competitive compensation would really help with retention.
