Amazon

Above average salary package. Offer fully remote work opportunity. Able to work with talented and collaborative engineers, lots of learning opportunities. Managers provide great support and flexibility to team members.

Average benefits, below average 401k matching, and the worst PTO in the tech industry, with only 10 days for first-year employees.

Many software tools are internally built but fail to keep up with industry standards.

Low work/life balance.

Freedom of choice on tech stack is limited to Amazon products and services; very few open-source alternatives are allowed.

As a senior engineer, you are better off taking other tech firms' offers. If you do choose to work for Amazon, I would suggest you stay a couple of years to learn the tech stack and systems well, so you aren't locked into its ecosystem and lose touch with industry trends.
