Think about exactly what roles you are interested in pursuing. Software developer/engineer is too broad.
Points to consider:
What are your non-negotiable requirements?
What does a healthy company culture look like to you?
What are your superpowers (what are you good at + comes naturally to you)?
What does a dream job look like to you?
