As vCluster Labs’ Senior QA Engineer, you will bridge the gap between rapid feature development and enterprise-grade reliability, owning the quality strategy for our core Kubernetes virtualization technology.
You will act as the gatekeeper of quality, starting with a hands-on, deep-dive approach to manual testing to establish the baseline before architecting our future automated frameworks.
As a Senior QA Engineer, your role will include:
Manual Validation & Strategy: Initially focus heavily on manual testing to gain a deep understanding of our product architecture. You will conduct exploratory testing to identify usability issues, edge cases, and regressions not yet covered by automation.
Backend Testing Expertise: Drive the testing strategy for our backend systems. You will dive deep into API interactions, database states, and Kubernetes resource management to ensure stability in complex distributed environments.
Path to Automation: Design and develop the roadmap for transitioning manual workflows into automated test frameworks (using Go or Python) for backend and UI testing.
CI/CD Integration: Eventually integrate automated tests into our pipelines (GitHub Actions, etc.) to ensure high-confidence, fast feedback loops for our engineering team.
Cross-Functional Advocacy: Collaborate closely with Engineering and Product teams to influence features early, advocate for testability, and align on quality standards before code is even written.
This role could be a fit for you if you bring:
Deep QA Expertise: 5+ years of experience in QA or Software Testing (with 1+ year in a senior capacity). You are an expert in backend testing and comfortable validating complex logic without a UI.
Kubernetes Fluency: Working knowledge of Kubernetes environments and distributed systems. You have the analytical skills to diagnose infrastructure-related issues, not just application bugs.
Automation Readiness: While this role starts manually, you possess strong programming skills in at least one language (Go preferred, or Python) and have the ability to build tooling and automation suites when the time is right.
Startup Adaptability: You thrive in ambiguity and can juggle multiple parallel projects. You understand that in a fast-moving environment, priorities shift, and you are capable of maintaining quality speed.
Ownership Mindset: You have strong initiative and are able to identify what needs to be done—whether it's writing a test plan or debugging a CI failure—and follow through independently.
Bonus points for:
Hands-on experience with major cloud providers (AWS, GCP, Azure).
Deep understanding of CI/CD systems (GitHub Actions, Jenkins).
Previous experience working with open-source commercialization or developer tooling products.
Experience working in or with distributed, remote-first teams.
We are a venture-backed tech startup striving to be the leading force in enabling platform engineers.
