As others have mentioned start with identifing the relevant functional safety standards for your industry. IEC 61508-3 and the annexes, whilst very verbose, is basically the textbook for safety development.
Pro tip, standards can be hard to find and expensive but you can rent or buy them cheaply from the Latvian Standards website (https://www.lvs.lv/), most are harmonised and exactly the same as IEC or ISO parent standards, just with an LVS cover sheet.
This book ,Embedded Software Development for Safety-Critical Systems by Chris Hobbs gives a great overview of safety software development in general and the key standards, I found it easy to read.
On a practical note if using C or C++ get familiar with commonly used language subsets such as MISRA (https://www.misra.org.uk) or CERT C, again which is more relevant will depend on industry.
Gimpel's PC-Lint is a commonly used static analyser for MISRA compliance, and you can try with it on their website (https://gimpel.com/demo.html), I haven't come across a free tool complete checker but you can do a lot with clang and GCC.
Some mention of Rust here but I think that would be a hard language to get through a certification process due to the limited options for qualified tools. That said there is work being done there, https://ferrous-systems.com/ferrocene
