Need advice: Back end engineer → infrastructure: how do you make the transition?

[gokuljs]

I’ve been a backend-heavy engineer for about 4 to 5 years, mostly in startups. For about 3 months I’ve been reading and building small things, but I’m not sure if I’m progressing or just spinning. I also don’t really have people around me in these areas, so I’ve mostly been trying to figure this out on my own, including using tools like GPT and Claude, but I still feel unclear.

My work includes APIs, some real-time systems like WebRTC and streaming, and debugging production issues such as latency, buffering, and reliability. I’ve used AWS, Docker, Redis, and similar tools.

I’m trying to move toward more systems-oriented work, such as infrastructure, distributed systems, or AI infrastructure like inference pipelines and data flow.

The problem is I feel stuck and scattered. I keep jumping between directions such as infrastructure, SRE or platform work, and AI infrastructure, and I don’t have a clear sense of what the actual path looks like from where I am.

Some questions:

How do people actually move from backend or product work into infrastructure or systems roles?

Is it better to pick one direction early, or explore broadly first?

How do you pick a theme or direction that actually compounds over time instead of second-guessing constantly?

What kinds of projects really signal readiness?

And practically, how do you start getting interviews without already having an infrastructure title?

Would really appreciate advice from people who’ve made this transition.

Thanks

My life strategy is second-guessing :P

But at the same time as you, after working for 5 years, I started learning like crazy. Diving deeper in the .NET framework, learning functional programming, making home-brew projects that do web scraping, data analysis, even some web development. Then Docker and Kubernetes... 100s of online courses, books, without clear intention or objective progress. But it did not frustrate me at that time as I was having fun.

Only after 2-3 years of doing this I noticed that I know some things, that when I go to a job interview I know more than the person interviewing me (not always). The knowledge compounds.

If you have a deliberate goal go for it. But if you just go for things that peak your interest that seems to work as well. It did for me.

Wow, okay, I do think like and calm myself.

Find some detailed job ads, and work backwards from there to see what skills are in demand.

What exactly do you mean by "infrastructure" or "systems"? At my organization, that basically means stuff like grafana, open telemetry, kubernetes, aws/azure, etc.

Your "AI infrastructure" is perhaps what other people call "MLOps" - data pipelines, airflow, that kind of stuff.

Both of those are different from each other, and also different from being a developer/SWE etc.

Its a bit annoying to me how these things have become segmented, I kind of preferred when it was all just "programming" or "computers" and most people did most things, but unfortunately these days the market is quite segmented / specialized, and the key to getting any particular job is to already be familiar with the popular tools in that space.

I think same

I'm curious, what's the reason for you to move toward more system-oriented work? Is it because you're looking for a way of career progression?

If so, I'd suggest you have some in-depth conversation with your manager and your mentor (if you have one), to identify area of skill developments for you, and opportunities for "learning on the job". And if your current situation/management won't afford you that opportunity, you should focus on finding a new job, which should be fitting for your current skill set, but with clear space for doing something more.

One path is that you could try to transitions within your current org. This should be particularly easy in startups, which is where you say your experience is, as startups have a lot less rigidity in roles/responsibilities and you could contribute to infrastructure efforts to build up context/knowledge.

From there, you can leverage that into an "official" infra role.

I don’t have a job right now. The next one I’m looking for is in this field.

And this is what I am doing right now, like I am just reading the DDIA book and writing the raft consensus algorithm in Go just for learning purposes
