  • Exciting challenges and growth while working at APS
    2026-03-06T01:07:36.227

    Pros: Lots of challenges = lots of career growth Ability to work with the latest tech on the market

    Cons: Maybe due to covid times, but there wasn't a whole lot of new-hires in entry level positions to delegate some of the challenges to.

  • Mostly positive
    2026-03-03T13:09:51.283

    Pros: Good benefits, decent pay, work-life balance.

    Cons: Constant reorgs, bureaucracy, management heavy.

  • Prestigious internship but highly competitive
    2026-03-02T21:56:25.810

    Pros: Prestigious company with a well-structured and highly organized internship program. Interns are kept actively engaged through meaningful projects, networking opportunities, and frequent company-hosted events. There is significant access to professionals across departments, making it easy to build connections and learn about different career paths. For interns who put in strong effort and actively network, full-time opportunities are possible (though not guaranteed). High-performing and well-qualified interns are given valuable responsibilities and growth opportunities.

    Cons: The company has a long legacy, and many employees have multi-generational ties to the organization. As a result, internal familiarity and prior connections can sometimes feel advantageous in competitive processes. Internship extensions are highly competitive, with only a small number selected per department from a large pool of candidates. Priority may be given to returning interns, which can make advancement challenging for first-time participants. The environment is strongly work-focused, and intern experiences can vary depending on team placement. Some managers appear to have limited capacity to take on interns, which may impact mentorship quality. Success in the program often requires strong technical preparation, initiative, and the ability to quickly adapt to unfamiliar or advanced responsibilities. For those without prior experience in the field, the learning curve can be steep.

Frequently asked questions about senior systems administrator 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 administrator jobs pay?

Across the postings here that list pay, the median is about $125,000 a year. About 5 in 10 of these postings list a pay range; the rest show an estimate, marked as one.

How many senior systems administrator jobs are there?

At our last count there were about 110 open postings. 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.
