Role

Who you are

5+ years in SDET, QA automation, or systems-focused software engineering
Strong Python skills for test frameworks, tooling, and automation
Practical experience with C in systems, testing, or infrastructure contexts
Solid Linux knowledge and understanding of distributed systems
Experience testing backend / infrastructure / storage / networking systems
Familiarity with Docker, Kubernetes, CI/CD, and observability tools
Comfortable reading production code, not just testing around it
Curiosity for research, experimentation, and deep technical problems

What the job involves

Virtuozzo is looking for a Senior Software Development Engineer in Test to help us validate and harden large-scale distributed storage and cloud infrastructure systems
This is not a UI-only or test-case-writing role
You’ll work close to the system, building serious test automation in Python and C, stress-testing real infrastructure, debugging performance bottlenecks, and influencing how our platform is designed and shipped
You’ll join our Storage team, working side-by-side with core R&D engineers, and collaborating with leading universities on applied infrastructure research
Design and evolve Python-based test frameworks for functional, performance, reliability, and stress testing
Build and operate production-like test environments for distributed storage and SaaS systems
Validate scalability, throughput, latency, tail latency, and failure scenarios
Debug system-level issues (performance regressions, race conditions, distributed failures) together with core engineers
Write low-level test utilities and probes in C / Go where Python is not enough
Integrate tests deeply into CI/CD pipelines and observability stacks
Collaborate with academic research teams on experimental labs and next-gen infrastructure ideas
Explore and evaluate AI-assisted testing approaches where they provide real value

Application process

HR introduction call
Team meeting: technical interview (1h-1.5h)
Hiring manager meeting (30minutes up to 1h)
QA advisor meet&greet (20minutes)

Our take

While the benefits of moving to the cloud have never been more evident, it is often beyond the means of most businesses that do not require the hyperscaling capabilities of enterprise cloud service providers. Virtuozzo offers an alternative: hosting, cloud and infrastructure as a service which can be customised by smaller providers and sold on to businesses at a price they can afford.

Virtuozzo competes for business with cloud service providers such as Amazon Web Services, Microsoft Azure and Oracle Cloud. However, it has a competitive advantage with small-to-medium businesses (SMBs) that aren't well served by enterprise solutions due to cost and difficulty of implementation. Its CEO believes that up to a third of the market for cloud services remains untapped by hyperscaling cloud providers, which gives Virtuozzo significant room to grow.

Virtuozzo has strategically expanded its reach through a series of acquisitions and partnerships. These initiatives extend beyond the development of its product, with talent acquisition strategies and efforts to strengthen its distribution network. These measures are geared towards capitalizing on the untapped potential within the underserved SMB market.
