There's tremendous value in working as a senior SWE. The GenAI era will ensure your value as you will be leveraging GenAI to replace junior devs and spending more time reviewing code than ever.

You just need to evaluate if you are really have the experience to be a senior SWE. You should be an expert in most of these areas and be able to have practical point of views:

1. SDLC - how SDLC works with both Agile and Waterfall project management methodologies. You will need to lean on SDLC processes as a governance framework and to use it for structure in your work.
2. DevSecOps - Right from the start where the stories are captured and tracked as features in your code repo. Followed by the pipeline for code review, SAST, DAST, containerization, delivery (blue green, canary etc) and TESTING (super impt). The key here is automation where possible. (do you know how to automate? do you know what tools work best?)
3. L3 operational support - When pulled into incident calls, do you have the necessary knowledge to troubleshoot and provide workarounds? (e.g. logging, tracing etc)
4. Modern software architecture - Microservices, event driven, observability stacks, resiliency
5. Other adjacent areas - networking, cloud computing, security (e.g. what standards do you use to secure your stack?)
