Job Summary:
We are seeking an experienced Senior Quality Assurance Engineer to lead the development and implementation of automated testing framework for our Lightway VPN protocol, which is implemented using Rust. In this role, you will be responsible for ensuring the quality, performance, and security of both the Lightway client and server by building scalable and efficient automated tests. Your work will directly contribute to the quality of our VPN service and help ensure that our Lightway protocol is secure, reliable, and performant across different environments and network conditions.
Key Responsibilities:
- Automated Testing Frameworks:
Design, develop, and maintain automated testing frameworks specifically for the Lightway VPN protocol built in Rust across multiple platforms (Windows, Linux, macOS, iOS, and Android). Ensure that automated tests cover all aspects of the protocol, including client-server interactions, encryption, connection stability, and performance. - End-to-End Automation:
Build and automate end-to-end test cases to validate the complete functionality of the Lightway VPN protocol. This includes creating tests for various networking scenarios, failover handling, and performance under load. - Security Testing:
Develop and execute security tests to assess potential vulnerabilities in the Lightway protocol. Ensure that encryption, authentication, and other security mechanisms are thoroughly validated and perform to the highest industry standards. - Performance Testing:
Conduct performance and stress testing to validate the protocol's scalability, stability, and resource usage. Simulate high traffic loads, variable network conditions, and large-scale deployments to identify bottlenecks and optimize performance. - CI/CD Integration:
Integrate the automated test suite into our CI/CD pipeline, enabling continuous testing with every code change. Ensure that testing is fully automated as part of the development and release process, reducing manual effort and improving release velocity. - Collaboration with Development Teams:
Collaborate closely with the Rust development team to understand protocol requirements, identify test coverage gaps, and ensure alignment with the product's quality goals. Provide feedback and recommendations on code quality, testability, and design. - Documentation and Reporting:
Create and maintain detailed documentation on the test strategy, test cases, results, and best practices for automated testing. Regularly report test coverage, defects, and any risks or concerns to stakeholders. - Continuous Improvement:
Continuously evaluate and improve the test automation framework, ensuring it remains scalable and adaptable to future protocol enhancements or changes. Stay up-to-date on the latest testing tools, best practices, and Rust-related testing techniques.
Qualifications:
- Education:
Bachelor's degree in Computer Science, Engineering, or a related field, or equivalent work experience. - Experience:
- 5+ years of experience in Quality Assurance and Automated Testing of Network protocols.
- Experience testing networking protocols (VPN, TCP/IP, DNS, HTTP/HTTPS).
- Proven experience with automated testing tools (e.g., Selenium, JUnit, TestNG, pytest, Rust-based testing frameworks).
- Familiarity with CI/CD pipelines and testing in an Agile environment.
- Technical Skills:
- Programming/Scripting languages: Strong proficiency in scripting languages (e.g., Python, Bash).
- Deep understanding of networking technologies (e.g., VPNs, IPSec, TLS, HTTP/HTTPS).
- Experience with performance testing tools.
- Familiarity with version control systems (e.g., Git).
- Security & Compliance Knowledge:
Experience with security testing practices and tools, including assessing encryption, authenticity, and confidentiality in network protocols. - Problem-Solving & Analytical Skills:
Strong ability to analyze complex issues and design effective automated test solutions, especially for low-level networking and protocol implementations. - Communication Skills:
Excellent verbal and written communication skills to effectively report issues, write clear test documentation, and collaborate with development and management teams.
Key Competencies:
- Attention to Detail:
High attention to detail, ensuring that all edge cases, security vulnerabilities, and performance bottlenecks are identified and addressed. - Collaboration & Teamwork:
Strong ability to work in a cross-functional environment with developers, product managers, and other teams to achieve shared goals and improve the product. - Critical Thinking:
Logical and analytical thinking with a focus on solving complex problems and optimizing testing approaches for a high-performance system like Lightway.
