    Does your current company have FM positions? Maybe you could work and learn at the same time. There are a lot of big name companies that are really investing in FM now that more tools are available. Here’s a list someone compiled that can give you an idea of where it’s being used in industry. I see some info is not quite up-to-date (e.g., IBM does have FM, or formal verification, in the US but I think most research is out of their Israel lab; Rockwell Collins is now Collins Aerospace after being acquired by UTC Aerospace).

    When you say "formal verification methods", what kind of techniques are you interested in? While using interactive theorem provers will most likely not become very widespread, there are plenty of tools that use formal techniques to give more correctness guarantees. These tools might give some guarantees, but do not guarantee complete functional correctness. WireGuard (VPN tunnel) is I think a very interesting application where they verified the protocol. There are also some tools in use, e.g. Mythril and CrossHair, that focus on detecting bugs using symbolic execution. There's also INFER from Facebook/Meta which tries to verify memory safety automatically. The following GitHub repo might also interest you, it lists some companies that use formal methods: practical-fm
