Core Responsibilities

Primary Functions

  • Design, develop, and maintain scalable, reusable automated test suites for web, mobile, and API applications using tools such as Selenium WebDriver, Playwright, Cypress, Appium, and REST-assured to ensure regression coverage and accelerate release cycles.
  • Build and continuously improve end-to-end test automation frameworks that integrate unit, component, integration, and system tests, adopting best practices like modularization, page-object models, and dependency injection.
  • Implement API and microservice test automation using HTTP clients and frameworks (Postman, REST-assured, Karate) including contract testing, schema validation, and automated negative/edge-case test scenarios.
  • Integrate automated test suites into CI/CD pipelines (Jenkins, GitLab CI, GitHub Actions, Azure DevOps) to enable automated build validation, nightly regression, and pre-release gating as part of the continuous delivery process.
  • Create and maintain robust test data strategies and synthetic data generation processes for reliable, repeatable automation across environments while ensuring data privacy and masking for PII-sensitive datasets.
  • Design automated performance and load tests (JMeter, Gatling, k6) to validate system scalability, report bottlenecks, and collaborate with SRE and backend teams to remediate latency and throughput issues before production.
  • Develop containerized test execution environments using Docker and Kubernetes to ensure consistent, isolated test runs and to support parallel test execution for faster feedback loops.
  • Implement and maintain infrastructure-as-code for test environments using tools like Terraform, CloudFormation, or Ansible to provision ephemeral environments for automated test runs and E2E validation.
  • Monitor and triage flaky or intermittent test failures; root-cause analysis to stabilize suites, reduce noise, and implement health checks and retries where appropriate without masking real defects.
  • Work with product owners and QA leads to define acceptance criteria, create BDD/TDD-style automated test scenarios (Cucumber, SpecFlow), and translate business requirements into executable automated tests.
  • Automate cross-browser and cross-platform test execution using cloud testing platforms (Sauce Labs, BrowserStack) and local grid setups to ensure consistent UX across supported browsers and devices.
  • Implement test reporting, logging, and observability for automation runs using tools like Allure, ReportPortal, ELK stack, or custom dashboards to provide actionable insights and traceability for stakeholders.
  • Participate in code reviews of test automation code and pipelines, enforce coding standards and test design patterns, and ensure automation repositories adhere to version control best practices (Git).
  • Support feature flag and canary release testing by automating targeted test runs for specific release routes and collaborating with release engineers to validate incremental rollouts.
  • Collaborate with security teams to add automated security/scanning checks (SAST/DAST) into CI pipelines and to automate tests that validate authentication, authorization, input validation, and common OWASP scenarios.
  • Architect and implement test parallelization strategies, shard suites, and optimize test selection to reduce overall pipeline runtime while preserving critical coverage for each deployment.
  • Mentor and onboard junior automation engineers by sharing framework patterns, code examples, pair-programming sessions, and documentation to scale team capability and knowledge transfer.
  • Drive continuous improvement initiatives: evaluate new automation tools, propose migrations (e.g., Selenium to Playwright or Cypress), and pilot proof-of-concepts to modernize the automation stack with attention to ROI and maintenance cost.
  • Maintain and own automation documentation including README, setup guides, test run instructions, and troubleshooting playbooks to lower the onboarding curve and reduce context switching.
  • Collaborate closely with development and QA teams during sprint planning to estimate automation effort, prioritize test backlog items, and ensure acceptance criteria are automatable and measurable.
  • Implement and manage test environment lifecycle automation: spin up/down ephemeral databases, mock services, and dependent APIs, and manage service virtualization where integration with third-party systems is not feasible.
  • Ensure automation aligns with regulatory and compliance requirements (e.g., PCI, HIPAA, SOC2), creating tests and controls that demonstrate compliance coverage for audits.
  • Track and report automation metrics (test pass rate, coverage, mean time to detect/resolve test failures, pipeline duration) and present actionable insights to engineering leadership to drive data-informed decisions.
  • Collaborate with cross-functional teams to design chaos and resilience testing scenarios, automate fault injection procedures, and validate service recovery and failover behavior under simulated conditions.
  • Evaluate and adopt test management tools (TestRail, Zephyr) and integrate automation runs to keep manual and automated coverage synchronized and visible to stakeholders.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis.
  • Contribute to the organization's data strategy and roadmap.
  • Collaborate with business units to translate data needs into engineering requirements.
  • Participate in sprint planning and agile ceremonies within the data engineering team.
  • Maintain and update automation backlog items, write clear tickets with reproduction steps, and collaborate to ensure timely resolution of automation debt.
  • Assist in release retrospective sessions to identify automation gaps and create remediation plans that reduce future manual testing overhead.
  • Conduct knowledge-sharing sessions and internal brown-bag trainings on automation best practices, new frameworks, and CI/CD improvements.
  • Help maintain test environments and coordinate with infra teams to schedule disruptive test runs (e.g., data migrations, large-scale performance tests).
  • Participate in vendor evaluations and manage relationships with third-party tool providers for test execution and cloud device farms.
  • Provide on-call support for automation pipelines and releases to troubleshoot failures, rollbacks, and last-mile validation checks during critical deployments.
