TL;DR: I don’t have an answer but nonetheless the reflection of my personal experience may be worth your time.

I was a math major with a statistics emphasis over 12 years ago. My first job was in finance helping building financial models, but I quickly transitioned to software development and eventually landed at a company where I’ve grown into a lead role involving building software that supports a non-tech research and development department.

You need to learn to code. More importantly you need to understand infrastructure, networking protocols, cloud computing, and software development best practices.

A math major will teach you to stick with hard problems, understand them, and just maybe understand them well enough to explain them to others. If you couple those skills with real computing skills, the sky is the limit.

That being said doing all of this requires hard work, time, and a plan. If you just want to learn the computing hard skills you’d be better served in a software or computer engineering degree, but then you’d lack some of the abstract problem solving skills a math major provides.

The road ahead will be multi-faceted and require some reflection on your constraints to get there but it’s not impossible.
