Software Development Engineer in Test and Research (Python / Systems)

Storage & Infrastructure | Europe (Remote)

Virtuozzo

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.

What you’ll work on

• 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

What we’re looking for

• 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 We Offer

• Remote and flexible working hours in European timezones
  

• Space for creativity and experimentation within the company’s goals
  

• Share Options – everyone shares in our success with share options
  

• We help our team get private medical insurance
  

• Supportive, engineering-driven culture with minimal bureaucracy
  

• The chance to influence Product and R&D decisions from day one
  

• A smart, friendly team that values reliability, simplicity, and automation
  

• Depending on your location and preferred employment method (B2B or employment), other perks and benefits apply

Process:

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