I'm in my second year of college and trying to choose a career direction. The part of programming I enjoy most is low-level and systems work. I started with C and socket programming, built servers, and studied TCP and UDP. More recently, I've been learning Linux networking, packet parsing, Ethernet, IP, ARP, ICMP, eBPF, XDP, AF_XDP, NIC queues, drivers, and DMA.
Most students around me are focusing on web development, mobile apps, AI/ML, or general data-structures-and-algorithms preparation. I've also heard that low-level networking has relatively few jobs and that networking careers mainly involve configuring routers and switches.
I'm specifically interested in programming and software engineering, not network administration or hardware configuration. My practical goal is to graduate with a strong software engineering job, so I don't want to spend the next few years specializing in an area with very few entry-level opportunities.
What software engineering careers involve C, sockets, Linux networking, servers, eBPF/XDP, packet processing, or performance-focused systems? Are there realistic entry-level roles, and which industries usually hire for them? Should I keep systems and networking as my specialization while also developing broader backend and software engineering skills?
I'd also appreciate advice on useful skills, open-source contributions, personal projects, internships, and computer science topics to focus on over the next two or three years. I'm not assuming I'll work directly on XDP; I'm mainly trying to understand whether systems programming, networking, and performance-oriented software are sensible career directions.

Start with manageable projects and build depth gradually. You don’t need to master drivers, DMA, eBPF, and every networking protocol at the same time. Finish a few projects, read real production code, contribute fixes to established open-source projects, and look for internships involving Linux, infrastructure, security, embedded systems, or performance engineering. Low-level networking is niche, but niche does not mean useless.
Other possible paths include firmware and embedded development, robotics, operating-system work, and networking hardware software. The work may be less visible than web development, but companies still need engineers who understand how software interacts with the operating system and hardware.
For a portfolio, build something small enough to finish but substantial enough to measure. An eBPF load balancer, packet monitor, userspace networking component, or high-performance server could all work. Explain the architecture, limitations, correctness concerns, and security tradeoffs, and include tests and reproducible benchmarks.
There isn’t one universal benchmark you need to beat. It’s more valuable to compare your implementation against a sensible baseline while varying request rates, packet sizes, connection counts, CPU usage, latency, throughput, and failure conditions. Be ready to explain why the results look the way they do rather than presenting impressive numbers without context.
There are real roles in cloud infrastructure, network infrastructure, kernel and driver development, embedded and telecom systems, cybersecurity tools such as packet inspection and IDS/IPS, and low-latency trading. Some firms do hire entry-level engineers for packet processing and kernel-bypass work, although the market is smaller and tends to have more senior positions than general backend development.
The best approach is usually to keep networking and systems as your specialization rather than making them your only skill. Continue studying data structures and algorithms, operating systems, concurrency, databases, testing, and general software engineering. That keeps you eligible for broader roles while giving you a useful differentiator. A strong general SWE candidate with substantial eBPF, XDP, or Linux networking projects can stand out much more than someone with only interview-preparation projects.
That makes sense. I’m currently building an eBPF load balancer after making a configuration-based epoll HTTP server. What would demonstrate real competence, and which kind of project would be strongest on a résumé?
