  • Develop testing strategies for services, microservices, and UIs within large-scale distributed systems.
  • Collaborate closely with developers, product managers, and DevOps engineers in Agile ceremonies to ensure that test coverage meets business requirements.
  • Participate in test planning and oversee the execution for designated features or product areas to support timely and high-quality releases.
  • Manage defects by logging, prioritizing, and tracking them using tools like JIRA.
  • Analyze test outcomes, produce quality metrics, and communicate risks and issues effectively.
  • Mentor junior QA engineers and support the implementation of automation best practices across teams.

Required Skills & Experience:

  • 4–6 years of hands-on experience in QA and test automation roles, preferably within Agile settings.
  • Proficiency in coding with Java, Kotlin, or similar languages, evidencing a track record of building sustainable test automation code.
  • Proficient in utilizing various test automation frameworks and tools for UI testing (Selenium, Cypress, Appium), API testing (REST Assured, Postman), and BDD tools (Cucumber, Serenity).
  • Strong background in CI/CD pipelines and tools such as Jenkins and GitHub Actions.
  • Familiarity with cloud-native architectures and container technologies like Docker and Kubernetes.
  • Experience in testing distributed systems and microservice architectures.
  • Strong analytical and problems-solving skills, coupled with excellent communication and collaboration abilities.

Nice to Haves:

  • Exposure to financial services, fintech, or trading system technologies.
  • Prior experience overseeing 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.

What You'll Gain:

  • Opportunities to contribute to and influence the test strategy for critical product components.
  • The opportunity to help shape the direction of test frameworks and tooling.
  • Chances to mentor junior team members and contribute to QA best practices.
  • A dynamic and collaborative team environment with modern DevOps and agile workflows.

Hi,
I need a custom ebay like site for bitcoins or using stock credit on it. I need it to let you pay the user verbally, like an agreement you agree on that's it. I need the site fixed so it can be upgraded in the future.
I need it to be fixed so you can upload something to the site and sell it.
All I ask is keep the buying and selling part verbal agreements only. Like sending the user stock credit virtually.
Bid on things on the website 
Sell things on the website
Buy things on the website
All I ask is keep the programming simple and the website in a simple form.
I need a website for the web browser and one for the phone web browsers.
If you can put in a custom user admin for it also, then that will be great.
Thank you,
Chris Clark (666 Encryption, CEO)
