Timezones are your main obstacle. Many companies are remote now, but work on the assumption that all their workforce is within 2-3 hours of the main timezone, and also that most work will happen synchronously. This includes (but is not limited to) meetings. You may want to narrow your search either to companies that embrace asynchronous work or where the manager you’ll be reporting to can agree to milestones, deadlines or deliverables that do not require much interaction with your colleagues.
