    Pros: treating employees very well and well maners

    Cons: nothing much to say so far

  • Great Company
    2025-12-12T03:47:22.480

    Pros: Strong team with plenty of impactful work to do. I was able to directly interface with and help the customer move things forward, no training wheels, or process to jump through. Subsidized health insurance premiums (Really Good Rates) Reasonable salary Natalie in HR is awesome. She really knows what she is doing, which is mirrored in the employee benefits.

    Cons: Lost one of their major long term customers, which is natural as the government can’t show favoritism. But, they lost two contracts back to back with the same customer, which cut their workforce by about 50%. This caused me to have to move on.

  • Healthy work life balance
    2025-11-17T10:01:54.850

    Pros: Great place to work with an excellent work-life balance. Leadership is supportive, the team culture is positive, and expectations are clear.

    Cons: The benefits package was good but had room for improvement in a few areas.

Frequently asked questions about senior systems engineer jobs

What is a ghost job?

A ghost job is a posting for a role the company isn't actively hiring for. Some stay up after the company fills the role. Others collect resumes for an opening that may never come.

You spend an evening tailoring an application, and nobody on the other side is looking for you.

What do senior systems engineer jobs pay?

Across the postings here that list pay, the median is about $151,000 a year. About 6 in 10 of these postings list a pay range; the rest show an estimate, marked as one.

How many senior systems engineer jobs are there?

At our last count there were about 1,200 open postings from about 440 employers. The list on this page is live, so the count above it is the current one.

How does Enhancv spot a ghost job?

Every posting goes through five checks: how long it has been up, whether a salary is posted, what employees say about the company, how specific the description is and whether it lists real requirements. Each job shows the checks it passed and the ones it didn't.

How fresh are the job postings?

Enhancv checks postings every hour, and every job shows how long ago it went up. Most hires happen within 30 days of posting. A listing that's been open for two months raises its ghost job risk.
