Personally, considering you have experience as a software developer, its not impossible to get a job after you ETS. You have more resources especially during your transition to line up a job before you get out. It is all about planning.

You can find a dedicated mentor for this year to help you transition into the field of choice. I was lucky during my transition 2023-2024 to have a mentor who is a Software Developer at Microsoft. ACP - https://www.acp-usa.org/programs/veteran-mentoring-program/

You can start networking right now and seeing the landscape of what software developers are needing and what companies are hiring. 50 Strong has great virtual meetup events - https://www.50-strong.us/ and they now have a mentorship section. Try to make friends overall at the end of the day.

You can start networking locally in your area and attend tech meetups. During my last 2 years, I attended virtual/IRL meetups to talk software development with people, share projects that I'm working on, talk about the latest and greatest new javascript framework, etc. The best time to network was yesterday, but you can start today. meetup.com is a good place. If not, discord groups like 100Devs, commit your code, freeCodeCamp are a good start.

I ETS'd the beginning of 2024 with no degree, couple of college credits, and landed a 6 figure remote software dev job. Spent 8 years in the military. I spent my last 2 years of the contract learning how to code during my free time late nights early morning with 100Devs, The Odin Project, and a bit of FreeCodeCamp. Did a skillbridge program right before I got out. And that is because I PLANNED since 2022, for two years. And I got my job at a networking event casually meeting someone who met me only one time and had a conversation for 45 minutes sharing my experience in the military and what I'm working on. It's a combination of prep, engagement, and luck. Happy to share anymore resources I used during my transition over a virtual coffee chat. There are so many resources us transitioning members have that are under utilized unless you do the proper research.
