I'm currently working as a QA engineer and want to transition into a new role, but I'm unsure whether to pursue DevOps or data engineering. In my spare time I've been learning Linux, Python, MySQL, CI/CD, Docker, Kubernetes, and Azure. I've also gained some exposure to OpenShift and Helm through work. Both fields seem interesting, but I'd like advice on which path fits my current skills better and how I can evaluate my abilities and build a practical learning roadmap.

Build one small system from start to finish rather than immediately taking another course. Use a simple application, put it in version control, containerize it, create a CI pipeline that runs tests and builds an image, and deploy it to a small Kubernetes cluster with Helm. Add ingress, secrets, logging, monitoring, and a basic rollback process. Then intentionally break things: use a bad configuration, kill a pod, fail a health check, expire a secret, or make a deployment fail. Your QA background is valuable here because DevOps is not just about getting the happy path working—it’s also about understanding and troubleshooting failure scenarios.
The tools you listed can support either path, so don’t choose only based on the technology checklist. DevOps often involves making reliable processes work for many teams, environments, and technology stacks, while data engineering focuses more on moving, transforming, modeling, and serving data. Try small projects in both areas and pay attention to which problems you enjoy solving when they become complicated. That’s a better indicator than simply liking the tools.
Your current skills point much more naturally toward DevOps. Docker, Kubernetes, CI/CD, Helm, OpenShift, Linux, and cloud platforms are already core parts of that work. Data engineering is a different direction, with more emphasis on data pipelines, data modeling, orchestration, and warehouses. DevOps would probably be the smoother transition, though you should still spend some time looking at the day-to-day problems in both fields and choose the one you genuinely enjoy.
That makes sense. I’ll continue with DevOps and work on getting beyond the surface level with Kubernetes and Helm. I’m also going to look for a practical way to test my skills instead of just collecting courses.
Your QA experience is not something you need to abandon completely. Skills in testing, automation, process analysis, and investigating failures can transfer well into DevOps, platform engineering, security, or infrastructure reliability roles. The market and job titles will change over time, so I’d focus on becoming strong at automation, cloud infrastructure, troubleshooting, and communicating how systems behave under failure rather than chasing a particular label.
Also consider security or platform engineering as a possible extension of the DevOps route. Your testing background could be useful for reliability, validation, and finding weaknesses in infrastructure and deployment processes.
