Senior Test Engineer
Senior Test Engineer needed to raise the quality bar across the products of a healthcare company that enables remote patient monitoring, clinical research, and personalized healthcare. You'll own the end-to-end test automation strategy for your product areas, build and scale reliable WebdriverIO suites across web, mobile, and API surfaces, and embed quality checks deep into CI/CD. You'll also bring AI-assisted testing into the team's day-to-day work, partner closely with engineers, product managers, and designers, and mentor junior QA engineers. This is a hands-on senior role for an automation specialist who operates independently in a fast-paced, distributed environment and drives consistent quality standards across teams.
What You'll Do:
- Design, build, and maintain robust end-to-end test suites in WebdriverIO and JavaScript
- Extend automation coverage across web, mobile, and API surfaces using complementary frameworks where appropriate
- Apply AI-assisted tooling to accelerate test authoring, triage flaky tests, and improve defect detection
- Define and own functional, regression, integration, performance, API, and end-to-end test strategies for assigned products
- Build and execute API test suites using Postman, REST Assured, or equivalent
- Partner with engineering on testability, observability, and shift-left practices
- Integrate automated tests into CI/CD pipelines and ensure they run reliably on every change
- Maintain Git-based workflows and code-review standards for test code
- Mentor junior QA engineers and review their test designs and code
- Document test strategies, results, and defects clearly for cross-functional, distributed teams
- Drive consistent quality standards, metrics, and review practices across teams
What We're Looking For:
- 6+ years of professional experience in software quality assurance, with a strong focus on test automation
- Bachelor's degree in Computer Science, Software Engineering, or a related technical field — or equivalent practical experience
- Expert-level proficiency in JavaScript as the primary scripting language
- Deep, hands-on expertise with WebdriverIO (WDIO) as the primary automation framework
- Hands-on experience leveraging AI-powered testing tools and AI-assisted development tools to accelerate test creation, maintenance, and defect detection
- Solid understanding of software testing methodologies across functional, regression, integration, performance, API, and end-to-end testing
- Proficiency with API testing tools such as Postman, REST Assured, or similar
- Experience integrating automated tests into CI/CD pipelines
- Strong working knowledge of version control systems (Git)
- Excellent analytical and problem-solving skills with strong attention to detail
- A proven ability to mentor junior engineers and drive quality standards across teams
- Strong written and verbal communication in English — you can clearly document test strategies, results, and defects, and collaborate effectively with cross-functional, distributed teams
An ownership mindset and the ability to operate independently in a fast-paced, international environment
Nice to Have:
- Working knowledge of Python or Java alongside JavaScript
- Experience with additional automation frameworks such as Cypress, Appium, Playwright, or similar
- Experience with performance and load testing tools (Locust, JMeter, k6, Gatling)
- Familiarity with containerization and cloud platforms (Docker, Kubernetes, AWS, Azure, or GCP)
- Experience testing AI/ML-based applications, including model output validation and prompt-based testing strategies
- ISTQB or equivalent QA certification
- Familiarity with security testing fundamentals, including common vulnerabilities (e.g. OWASP Top 10), authentication/authorization testing, and secure API testing practices
- Hands-on experience with web proxy and security testing tools such as Burp Suite, OWASP ZAP, Charles Proxy, or Fiddler for traffic inspection, request manipulation, and vulnerability discovery
