Intern in Kernel team

Intern in Kernel

Virtuozzo offers an exciting internship opportunity in the Kernel team for Alumni of Constructor University Bremen. During this internship, you, together with the other interns, will learn and be supervised/mentored by our Senior and Principal team members.

Virtuozzo works deep in Linux virtualization, containers, storage, and low-level infrastructure. The kernel team works on Linux internals and virtualization-related components, including container isolation, memory management, I/O paths, eBPF-based observability, and QEMU/KVM integration. 

The goal of this internship is to help research, prototype, implement, and test low-level Linux functionality for virtualization and container platforms. The intern will work with experienced kernel engineers on real engineering tasks involving C, Linux APIs, kernel/user-space interfaces, debugging, tests, and performance validation. The final result should include a working prototype or implementation, tests or benchmarks proving correctness and performance, and documentation describing the design, limitations,  and integration approach. Where applicable, the work may be prepared for internal review, product integration, or upstream contribution. 

Candidate Requirements 
1. Senior-level Computer Science undergraduate or graduate student, or recent alumni of Constructor University.
2. Strong foundation in operating systems, especially Linux. 
3. Proficiency in C; Python is a plus for tests, automation, and tooling. 
4. Desire to dig into Linux kernel internals and understand how low-level systems work. 
5. Basic understanding of kernel/user-space interfaces, filesystems, memory, I/O, containers, or 
virtualization. 
6. Familiarity with QEMU/KVM, eBPF, kernel modules, or x86 assembly is a plus, but not 
required. 
7. Research-oriented mindset: ability to read technical documentation, investigate unfamiliar 
areas, design experiments, work independently, and communicate findings clearly. 

Compensation: 1,000 EUR/month, full-time. 
Expected Duration: 3 months full-time during the summer, with possible full/part-time 
extension. 
Team Size: 2 students. 
Location: Fully remote. 
Start Date: June 1st.
