quality engineer (auto) for cloud infrastructure

Nexcess provides specialty cloud solutions for organizations that need to combine performance and compliance. It serves businesses worldwide, from agencies scaling client sites to enterprises running mission-critical operations.

• Own quality end to end within the Compute Solutions domain
• Take responsibility for validating changes across VPS, Cloud Dedicated, storage, and bare metal products from specification through development, deployment, and production
• Build and maintain automated testing frameworks and test coverage
• Develop automated tests for infrastructure and application changes, including regression, integration, and failure-path scenarios
• Define testing strategies early in development
• Identify risks, dependencies, edge cases, and operational failure scenarios before implementation is complete
• Translate requirements into clear, testable acceptance criteria
• Work with engineers and stakeholders to remove ambiguity and make expected behavior objectively verifiable
• Validate changes across complex infrastructure environments, including interactions between compute, virtualization, storage, networking, and supporting software components
• Verify changes and provide evidence, including meaningful test results, coverage, and validation of expected behavior and failure scenarios in pull requests
• Use AI-assisted engineering tools daily for testing, automation, and review; critically validate generated output and remain accountable for the final result
• Review other engineers’ code and test changes, identify quality, reliability, and operational risks early, and provide actionable feedback
• Improve testing efficiency by replacing repetitive validation work with reliable automation where practical
• Participate in incident analysis, identify test coverage gaps, and improve automated testing and engineering practices based on production issues
• Build effective test coverage for complex, legacy, unfamiliar, or existing systems without unnecessary rewrites
• Mentor engineers in quality practices and share testing approaches, automation techniques, and quality standards
• Coordinate quality dependencies across teams and ensure cross-team changes are tested appropriately
• Own features end to end, clarify unknowns up front, and deliver live, monitored changes
• Write precise specifications before coding and resolve ambiguity in writing with requesters
• Run the AI harness daily, use agentic tooling and automated pull-request reviews, and build reusable skills to share with the team
• Include tests with every change, gate on changed-code coverage, and exercise failure cases as well as happy paths
• Review designs promptly, identify problems while they are inexpensive to fix, and provide specific feedback
• Pair with less experienced engineers on complex changes, explain reasoning, and provide timely feedback
• Take part in the on-call rotation, document incidents and actions, reduce toil, and document knowledge to avoid a single point of failure
• Read and safely modify unfamiliar code, and improve its instrumentation
• Identify dependencies early, coordinate directly with their owners, and resolve them ahead of related work

• 5+ Years of experience with automated testing frameworks and software quality engineering
• Strong experience designing, building, and maintaining automated test suites for production systems
• Experience testing complex environments with multiple infrastructure or application components
• Strong understanding of functional, integration, regression, and failure-path testing
• Experience defining test strategies and translating requirements into clear, testable acceptance criteria
• Experience working closely with engineers throughout the development lifecycle, not only after development is complete
• Ability to read application or infrastructure code to identify risks, test gaps, and potential defects
• Experience with production systems and incident analysis, using production issues to improve test coverage
• Hands-on experience using AI-assisted engineering or testing tools in daily technical work
• Strong written communication skills and ability to work effectively in a remote, distributed team across multiple time zones
• 5+ Years in software engineering, building and running production software, with ownership of shipped work after release
• Depth in at least one part of a production system and ability to understand unfamiliar parts; able to review code in a language not used daily and identify problems
• Able to specify requirements precisely, critically review generated code, identify its failure modes, and explain pre-merge checks
• Habit of writing tests alongside changes, gating on changed code, and using tests to catch mistakes
• Experience operating systems built, including a production on-call rotation, ownership of an incident, and a follow-up write-up that led to a change
• Clear written communication, with decisions and trade-offs recorded for colleagues across time zones
• Будет плюсом: 5+ years of KVM or Linux server administration, Perl, PHP, React, or Vue, testing virtualization, VPS, bare metal, storage, or cloud infrastructure, managed hosting, cloud platforms or other high-availability services, CI/CD-integrated automated testing, mentoring engineers or establishing team quality and testing standards

• Pay range: $82,000
• Full-time employment
• Remote work with the option to use the co-working space in Bratislava
• Excellent pay and all necessary equipment
• Employee referral program with bonuses for successful referrals
• Support with legalization in Slovakia if needed
• Opportunity to practice and improve English
• Work in an international-level team of professionals
