I'm in my second year of college and trying to decide how much to specialize in systems and networking. I enjoy lower-level programming much more than typical web or app development. I started with C and socket programming, building servers and learning how TCP and UDP work. More recently, I've been exploring Linux networking, packet parsing, Ethernet, IP, ARP, ICMP, eBPF, XDP, AF_XDP, NIC queues, drivers, and DMA.
Most students around me are concentrating on web development, mobile apps, AI/ML, or standard data structures and algorithms interview preparation. I've also heard that low-level networking has relatively few jobs, and that networking careers are mainly about configuring routers, switches, or hardware. I'm primarily interested in software engineering rather than network administration or hardware configuration.
My goal is still to graduate with a strong software engineering job. I don't want to spend the next two or three years specializing in an interesting area only to find that there are very few entry-level opportunities.
What kinds of software engineering careers involve C, sockets, Linux networking, servers, eBPF/XDP, packet processing, or performance-focused systems? Are there realistic entry-level roles, or are most positions aimed at experienced engineers? Which industries hire for this work?
Should I keep systems and networking as my main focus, or combine that specialization with more conventional backend development and software engineering fundamentals? Over the next few years, which skills, open-source contributions, personal projects, internships, or computer science topics would best improve my employability while keeping me close to systems and network programming?
I'm not assuming I'll work specifically on XDP. I'm trying to determine whether the broader path of systems programming, networking, and performance-oriented software is a sensible career direction.

Start with manageable projects and build depth gradually. You don’t need to understand every part of the Linux networking stack, drivers, and hardware at the same time. A solid progression could be a reliable concurrent server, packet capture and parser tools, an event-driven proxy, an eBPF observability tool, and then a more advanced load balancer or userspace networking project.
Along the way, learn how to use Linux profiling and tracing tools, write tests, inspect packets, reason about concurrency, and diagnose failures. Open-source contributions and internships in operating systems, infrastructure, security, embedded software, or cloud networking can be especially valuable. Low-level networking is niche, but niche does not mean useless—just make sure your fundamentals remain strong.
Look at infrastructure and networking teams at cloud providers, content-delivery companies, network equipment and operating-system vendors, cybersecurity firms, telecom companies, and firms that care about very low latency. The work can involve packet processing, kernel bypass, traffic balancing, observability, drivers, or high-performance service infrastructure—not necessarily configuring routers.
For a portfolio, finish one focused project instead of collecting lots of unfinished experiments. An eBPF-based load balancer could be useful if you document the design, limitations, test setup, and results. You could compare it with a conventional implementation, measure throughput and latency under different workloads, explain CPU and memory usage, and include reproducible benchmarks. The point is not to hit one universal benchmark number; it is to demonstrate that you can design, measure, debug, and explain a system.
There are genuine software careers in this area, although it is a smaller niche than general web or backend development. Potential paths include cloud infrastructure networking, kernel and driver development, embedded and telecom systems, cybersecurity tools such as packet inspection and intrusion detection, high-performance servers, and low-latency trading.
Some of these companies do hire new graduates, but many roles become easier to reach after gaining broader software engineering experience. Keep studying data structures and algorithms, operating systems, concurrency, debugging, testing, and general programming practices. Those skills help with interviews and keep your options open.
A good strategy is to make systems and networking your specialization rather than your only skill. A candidate who can handle normal software engineering work and also show meaningful eBPF, XDP, or network-performance projects can stand out considerably.
That makes sense. I’ll keep building my networking projects while also working on interview preparation and broader software engineering fundamentals.
I’m currently working on an eBPF load balancer and have already built a configuration-driven epoll HTTP server. I’ll focus on documenting the architecture and comparing performance rather than just listing the project on my résumé.
