Leaving React/Serverless for Elixir/Phoenix: bad career move?
Current stack: 1YOE, React/Redux, TS/JS, Serverless, AWS/Lambda,Mongo. ~5k active users, ~10 engineers. ~10LPA, service/india based consultancy, us market.
Have an offer for ~100% hike, but role is mostly Elixir/Phoenix/LiveView + some Gatsby/Python/ML. Much smaller shop, ~2–4 engineers, smaller scale, public-good work. India.
I want to become a stronger engineer and eventually be competitive for stable, reliable corporate engineering roles later.
Would leaving the React/Serverless ecosystem for Elixir hurt my future employability? Or is learning a very different stack, BE/concurrency/distributed-systems thinking etc actually valuable?
Would you take this move? What would concern you?
