Jack of all trades, master of none is a figure of speech used in reference to a person who has dabbled in many skills, rather than gaining expertise by focusing on one.
The shortened version “a jack of all trades” is often a compliment for a person who is good at fixing and has a very good broad knowledge.
The complete sentence is “Jack of all trades, master of none is often times better than a master of one”.
Goal is to incentivate people to branch out, like learning Optimization but also Core, and also Data Science (programming), etc…
In Telecom we can say the E2E professional. That’s why i think it’s GOOD.
Why Being a Jack of All Trades Makes More Sense in Telecom Jobs Today?
Telecom is an ever-changing world, and it is evolving faster than ever.
In an industry once dominated by specialization, the Telecom sector is undergoing a transformation where versatility is no longer a nice-to-have—it’s a must-have.
Traditionally, telecom careers followed a linear path: RF engineers focused on coverage, core engineers handled switching, and transport teams ensured connectivity. But today, with the convergence of technologies—5G, AI, cloud, cybersecurity, edge computing, and soon 6G—those clear lines are blurring. The new era calls for professionals who can speak multiple technical languages, connect the dots, and work seamlessly across domains.
“In Telecom’s new era, versatility isn’t optional—it’s your unfair advantage.”
The Evolution of Telecom: From Rigid Networks to Agile, Cloud-Driven Ecosystems
Legacy to Modern Networking The days of monolithic, hardware-centric telecom networks are fading. We’ve moved from fixed-function boxes and siloed architectures to software-defined networks (SDN) and network function virtualization (NFV). This shift demanded that telecom engineers learn networking concepts traditionally found in IT and cloud computing.
Cloudification of Telecom - As networks evolved, so did deployment strategies. Cloud adoption began slowly, with operators experimenting with hybrid models. Today, the movement is full-speed ahead toward cloud-native telecom infrastructures—scalable, containerized, automated, and service-based.
Cloud-Native: A New Must-Have Skillset Understanding Kubernetes, CI/CD, observability, and DevOps practices is no longer just for cloud engineers. Telecom professionals across the board—RAN, Core, Transport—need to grasp these concepts to remain relevant in an environment where infrastructure is now code.
AI/ML & GenAI: The New Power Tools AI and ML are powering use cases like network optimization, anomaly detection, customer experience enhancement, and predictive maintenance. Now, with GenAI, we’re stepping into a world where intelligent assistants help with config generation, automated troubleshooting, knowledge management, and even training.
