About Termius Termius is a Modern SSH Client that redefines how engineers interact with remote systems. Millions of engineers and thousands of companies rely on Termius worldwide. While AI has transformed modern IDEs, a terminal stays the same inefficient technology since the 1970s. As a leading cross-platform SSH client, our mission is to boost productivity and foster collaboration by rebuilding the Terminal for the modern era. About the Role We are actively growing and seeking a Quality Assurance Engineer who will help us improve product reliability and raise the quality bar across the delivery lifecycle. You’ll work closely with engineers, product, and design to ensure quality is built-in from feature planning and implementation to release validation, incident follow-ups, and prevention work. The testing scope includes multiple platforms: Desktop (Windows, Linux, macOS), Mobile (iOS, Android), and Web. What you will do: Test new features end-to-end and validate changes across our product, ensuring consistent behavior and a smooth user experience. Collaborate with engineers early in the development cycle: clarify acceptance criteria, identify risks, and propose validation approaches before implementation is finished. Create and maintain high-signal test artifacts (test plans, checklists, and test cases) that support fast and confident releases. Investigate and report issues with clear reproduction steps, expected vs actual results, logs, and supporting evidence. Help build and maintain quality gates: ensure the right coverage exists and that regressions are caught early. Contribute to automated testing (Playwright) where it makes sense (e.g., regression coverage, stability improvements) and help reduce flakiness. Participate in defect escape analysis (DEA) and incident reviews: help identify root causes, verify fixes, and follow up on preventive actions Maintain and improve test environments and tooling (local setups, test data, build distribution, release verification workflows). What we’re looking for: Proactive and self-driven: you take initiative, can self-organize, and don’t wait for tasks to be assigned. Investigative mindset: you dig deep into problems and can explain impact and risk, asking “Is this the most valuable thing to do right now?” End-to-end ownership: you consistently deliver outcomes and follow through until the work results in a real improvement. Beyond just testing: you can help shape testing strategy, contribute to quality gates, analyze escapes, and support engineers with test planning. Solid QA experience: you understand core testing concepts, can work with complex systems, and communicate clearly and precisely. You actively stay up to date with QA practices and industry trends, can explain what’s changing in the field, and apply new approaches in a practicalway. Strong collaboration: you work well with engineers, support teams, and stakeholders, and can drive discussions to clarity and action. Your day might look like: Reviewing RC builds and focusing testing on high-risk areas. Reviewing user requests in a support system to identify recurring pain points and translate them into test scenarios. Reviewing QA checklists and (when applicable) automated tests in Pull Requests. Pairing with an engineer to debug a flaky test, analyze logs, or validate a tricky edge case. Joining a team’s stand-up to align on scope, risks, and readiness. Running or participating in retros / incident reviews and tracking action items to completion. Updating test plans, checklists, and test cases based on new functionality and real incidents. Why Join Termius: Your contributions will directly influence the experience of millions of engineers and shape the future of system management tools The speed and quality of decision-making depend on the accessibility of information. We aim for full transparency in all our actions We share and ask for the candid feedback needed to become great We build for system engineers and aim to make complex things feel simple and visually appealing Be part of a culture that values proactiveness, a fail-fast-learn-fast approach, and a strong sense of ownership. What do we offer: A full-time position and longevity benefits: paid vacation, sick leaves, and flexible time off. Comprehensive support for remote employees, including equipment and professional development resources. Join us If you're an experienced self-sufficient individual contributor passionate about product development and excited to make a significant impact, we'd love to hear from you. Please submit your resume and cover letter detailing your experience and why you're a great fit for this role.
