Oracle

Great technology (even if they discourage employee dogfooding).

If you are being hired by Oracle, the starting pay is well-above-average, and you can even negotiate your IC level as part of the hiring process.

OCI makes some attempts at Internet culture (free snacks including limited fresh fruit).

The education benefit is above-average, though it won't pay for your entire degree. If you are on a greenfield project, then you will have time to pursue this.

IF you are acquired by Oracle (or will be):

• Your out-of-pocket insurance costs will go way up.
• You will be put on-call without additional compensation.
• You will spend years watching your pay scale fall behind the industry. New positions will have a "pay range" and you will be underwater.
• You will be given false promises that your project won't be canceled. They don't mean to lie.
• Technical debt will grow exponentially. Expect a brain drain, additional processes so that all tasks take longer to do. Then "unfunded mandates" (like: "migrate everything from GH to BB") will cause all the Chef and Ansible to break, and your short-term workarounds will become permanent extra work.
• Any work you want to do to improve supporting the product will need approval. If you get paged at 4 AM twice a month, but there's no customer impact, then you are not allowed to fix the issue, even if you promised to put in extra hours to do so. That will just be viewed as you're not putting in enough time for the prescribed tasks.

If you are on a legacy project, you will be promised you won't be fired, but not in writing. They will not find a place for you (see the Solaris folks for example). You will be allowed to reapply for any open job; however, since your skillset atrophied, you won't likely qualify and you will feel out of time applying somewhere else.

Basically, you want to leave Oracle BEFORE change of control. That way, if you decide to come back, you don't need to wait the full 2 years that other employees must wait.

Oh, if you're not acquired, I'd recommend a 24-month tour.

None. Seriously. Management knows about problems way before they get to the courts. There is so much engineer attrition; the way the company survives is by rewarding the bloated management class.
