If the op is looking only for remote roles then I'd emphasise that competition for these is extremely high. My advice would be to broaden your search to include hybrid and-in person roles.

I wish that rto was being handled with more flexibility and empathy, and I appreciate that travelling to work can be very difficult to reconcile with location and parental/caring responsibilities, but this is unfortunately where we are.

I'd also recommend looking beyond startups and pure software/tech companies. There are many businesses in eg manufacturing, or in less mainstream locations, that struggle to hire decent devs.

For context: I'm a UK-based developer and have recent experience of a fairly substantial period of unemployment. I now have a job with a great business, but also with a substantial commute.
