About the Role
Rannlab Technologies is looking for a highly skilled QA Engineer to take full ownership of testing our large-scale Digital Signature Certificate (DSC) platform. This is not a routine QA role — we need someone who can think like a user, break systems like a hacker, and build test automation that scales.
As the platform moves towards serving 10,000+ concurrent users, your mission is to ensure 100% reliability, security, and performance — from UI to APIs to data layers.
Key Responsibilities
Design and execute end-to-end test plans for both manual and automated workflows
Build and maintain automation test suites using tools like Selenium, Postman, JMeter, or Cypress
Perform VAPT (Vulnerability Assessment and Penetration Testing) to identify security loopholes
Conduct load, stress, and performance testing to validate platform readiness for 10,000+ concurrent users
Collaborate with developers to ensure coverage of unit tests, integration tests, and regression tests
Create reusable test templates, data sets, and documentation
Own bug tracking, triaging, and sprint QA sign-off
Monitor test coverage and continuously optimize test pipelines
Verify API responses, authentication flows, and data integrity for digital signature workflows
Test across devices and browsers for responsiveness, UI consistency, and accessibility
Required Skills & Experience
5 years of QA experience in a product or SaaS environment
Proficient in manual testing, test case writing, and bug reporting
Hands-on experience with automation tools (Selenium, TestNG, Cypress, or similar)
Strong knowledge of VAPT, OWASP top 10, SQL injection, XSS, and other common vulnerabilities
Experience with performance testing tools like JMeter, Gatling, or LoadRunner
Ability to simulate and test high-concurrency environments (10k+ users)
Understanding of REST APIs, JWT, and secure authentication flows
Familiarity with Git, CI/CD pipelines, and QA automation integration
Knowledge of PostgreSQL basics for data validation
Strong debugging skills and a proactive mindset to explore edge cases
Nice to Have
Experience testing systems involving eKYC, Digital Signatures, or government tech platforms
Knowledge of compliance frameworks like ISO 27001, SOC 2, or IT Act security protocols
Exposure to containerized environments (Docker, Kubernetes)
Experience with monitoring tools like Grafana, Prometheus, or ELK stack
What You’ll Get
A chance to test and secure a platform of national importance
Ownership over all things QA — automation, performance, and security
A fast-paced, product-first culture where quality is a top priority
Exposure to digital security, SaaS scaling, and high-load systems
