    • Champion quality practices within the team by advising on testability during design and implementation phases
    • Drive testing strategies across services, microservices, and UIs for large-scale distributed systems
    • Collaborate with developers, product managers, and DevOps engineers in Agile ceremonies to ensure test coverage aligns with business needs
    • Contribute to the test planning and own the execution for assigned features or product areas, ensuring timely and high-quality releases
    • Log, prioritize, and manage defects using tracking tools like JIRA
    • Analyse test results, generate quality metrics, and clearly communicate risks and issues
    • Mentor junior QA engineers and help drive automation best practices across teams

Required Skills & Experience

    • Strong coding skills in Java, Kotlin, or similar languages, with demonstrated experience building maintainable test automation code
    • 4-6 years of hands-on experience in test automation and manual QA roles, ideally in Agile environments
    • Proficient in using test automation frameworks and tools such as:
    • UI Testing: Selenium, Cypress, Appium
    • API Testing: REST Assured, Postman, SoapUI
    • BDD Tools: Cucumber, Serenity
    • Database Testing
    • Solid experience with CI/CD pipelines and tools (e.g., Jenkins, GitHub Actions)
    • Familiarity with cloud-native architectures and container technologies like Docker and Kubernetes
    • Experience testing in distributed systems and microservice architectures
    • Strong analytical and problem-solving abilities
    • Excellent communication and collaboration skills

Nice to Haves

    • Exposure to financial services, fintech, or trading system technologies
    • Experience leading test strategy for medium-to-large projects or components
    • Familiarity with tools like XRAY, TestRail, Grafana, Kibana, or Prometheus for test management and observability
    • Understanding of performance, reliability, or security testing approaches
    • ISTQB/CSTE certification

What You'll Gain

    • Opportunities to contribute and shape the test strategy for key product components
    • The chance to help shape test frameworks and tooling direction
    • Opportunities to mentor junior team members and contribute to QA best practices
    • A fast-paced, collaborative team environment with modern DevOps and agile workflows

Is Kotlin a good career?

Yes, Kotlin is a good career choice for developers who want to work in the Android app development, backend development, or cross-platform development space

Kotlin is a modern programming language that was designed to improve upon some of the shortcomings of Java, making it more concise, safe, and interoperable with other languages

Here are some reasons why Kotlin is a good career choice:

  1. High Demand: Kotlin is in high demand in the technology industry, especially in the Android app development space. Many companies are now using Kotlin to develop their Android apps, and the demand for Kotlin developers is growing rapidly.
  2. Compatibility: Kotlin is interoperable with Java, which means that developers can use both languages in the same project. This makes it easy for developers to migrate from Java to Kotlin and vice versa, and it also makes it easier to integrate Kotlin into existing Java-based projects.
  3. Easy to Learn: Kotlin is relatively easy to learn for developers who are already familiar with Java or other similar programming languages. Kotlin has a simpler syntax than Java, making it easier to read and write code.
  4. Concise and Safe: Kotlin is a more concise language than Java, which means that developers can write less code to achieve the same functionality. Additionally, Kotlin has built-in null safety features that help developers avoid common errors and bugs.
  5. Career Growth: Kotlin is a relatively new language, which means that there is a lot of room for growth and innovation. Developers who are proficient in Kotlin have the opportunity to contribute to the development of the language and its ecosystem, which can lead to career growth and advancement.
