SDET Engineering Manager (remote-only, worldwide remote)

TuxCare is a subsidiary of CloudLinux. It offers a portfolio of security solutions for Linux and open-source software aimed at enterprise organisations. With TuxCare, enterprises can automate live vulnerability patching, minimise downtime, keep their applications secure and compliant, and get support from a team that knows Linux security best — covering the most popular Linux distributions, end-of-life systems, programming languages, and much more.

One of TuxCare's key products is Endless Lifecycle Support (ELS), which enables organisations to securely continue using Linux distributions and software languages that have reached end of life or no longer receive standard security updates. ELS delivers vulnerability patches for unsupported versions of CentOS, Ubuntu, Debian, Oracle Linux, as well as for runtimes and frameworks such as PHP, Python, Spring, Angular/AngularJS, Django, and Flask.

We're looking for a Head of QA who can transform a technically capable but operationally strained QA team into a strategic, AI-powered quality engineering function. This is the opportunity to fundamentally rethink how we assure quality at scale — across Linux package testing, multi-distro coverage, and a growing CI/CD automation footprint.

Work is fully remote, with flexible hours, where you can plan your day and work from anywhere in the world.

What You'll Own

1. Strategy & Architecture:

• Define key product quality metrics and build a strategic multi-quarter QA roadmap
• Execute the defined QA roadmap and hold the team accountable to it
• Expand test coverage systematically: prioritise by risk and customer impact, not by noise
• Own the test system infrastructure and the resource strategy
• Drive adoption of AI tooling across the QA function — from test generation to failure triage

2. People & Execution:

• Build a team culture focused on heavy AI and automation usage
• Restructure on-duty rotation so it's equitable and sustainable
• Mentor SDETs from "test writers" to "product quality engineers" who own subsystems end-to-end
• Create clear career growth paths within the QA function
• Collaborate closely with developers; translate quality signals into actionable development priorities

Tech Stack:

• Test Framework — pytest, Python, Playwright (emerging)
• Scripting — Bash / Shell (package environments, multi-distro testing)
• CI/CD — Jenkins, GitLab CI (migration target)
• Infrastructure — OpenNebula, KubeVirt, Docker, Ansible, S3/Ceph
• Reporting — Allure Framework, Redash / ClickHouse
• Communication — Slack, Jira

Must Have

• 5+ years in test automation; 2+ years leading a QA team of 3+ engineers
• Deep experience with Linux-based product testing: RPM/DEB packages, systemd, multi-distro matrix
• Strong Python skills — the entire test framework and tooling is Python
• Proven track record of dramatically improving test reliability and coverage metrics
• Experience building or integrating AI/ML into QA workflows — not theoretical, show what you shipped
• CI/CD pipeline architecture experience (Jenkins Pipelines; GitLab CI migration is upcoming)
• Fluent in Linux CLI and shell scripting — package environments require comfort at the system level
• English — Upper-Intermediate (B2) or higher

Must Demonstrate

• Strategic thinking: you see the system, not just the ticket; you plan quarters, not just sprints
• Delegation instinct: you build processes that distribute and track ownership, not a single point of failure
• Data-driven execution: you measure, set targets, and hold teams accountable to metrics
• Strategic initiative: you proactively propose and drive improvements — you don't wait for problems to be assigned
• Automation bias: if a human does something daily (like a nightly report), it should be automated — period

Nice to Have

• VM orchestration or cloud infrastructure testing experience
• Experience testing security patches and package updates, including kernel-level patches for Linux distributions
• Experience with multi-distro Linux testing matrices at scale
• Hands-on experience with Linux packaging ecosystems (RPM, DEB, APK), repository management, and security advisory formats (OVAL, CSAF)
• Hands-on understanding of vulnerability lifecycle: CVE intake, patch validation, regression testing of security fixes, advisory generation (OVAL / CSAF) — you'll be testing patches, not features

What's in it for you

• A focus on professional development
• Interesting and challenging projects
• Fully remote work with flexible working hours — schedule your day and work from any location worldwide
• Paid 24 days of vacation per year, 10 days of national holidays, and unlimited sick leave
• Compensation for private medical insurance
• Co-working and gym/sports reimbursement
• Budget for education
• The opportunity to receive a reward for the most innovative idea that the company can patent
