Do you have any recommendations for someone earlier in their career (<50 yo) to avoid or minimize ageism? Go into management? Be prepared to pick a new career?
Yea going into management is the best bet. Its a "controversial" topic on HN because large swathes of ppl here here believe #IC4Lyfe is a good career move. Its not.
It's the industry.
I work with this guy, he's about 60. I think he has a degree in Physics from Oxford, but he has a Texas accent. He's kind of a nomad type of guy, bounces from job to job. Got hired into the AWS "Cloud Team" shop on a project I work on. Doesn't have any AWS certifications. As far as I know, barely touched AWS and never touched Python, CloudFormation, or Jenkins before this job (but he knows just about every *ix flavor there is). Basically a lifelong Linux Sysadmin. I have no idea how he got the job.
Within a month he was writing his own CloudFormation, Lambdas, and Jenkinsfiles. He almost immediately intuited the whole "Zip up the Python and all its dependencies, throw on S3, use CFT to deploy the Lambda using that Zip file" method of deploying lambdas. Note this is with multiple accounts so you need to get the whole IAM delegation between accounts stuff. He's a natural.
I'm in awe of this guy.
I truly believe that HN is full of people than can be like this. The problem is that most hiring managers do not.
