SDET – Regression Automation Engineer

Job description

**Join Our Team** Oowlish, one of Latin America's rapidly expanding software development companies, is seeking experienced technology professionals to enhance our diverse and vibrant team. As a valued member of Oowlish, you will collaborate with premier clients from the United States and Europe, contributing to pioneering digital solutions. Our commitment to creating a nurturing work environment is recognized by our certification as a Great Place to Work, where you will have opportunities for professional development, growth, and a chance to make a significant international impact. We offer the convenience of remote work, allowing you to craft a work-life balance that suits your personal and professional needs. We're looking for candidates who are passionate about technology, proficient in English, and excited to engage in remote collaboration for a worldwide presence. **About the Role:** We are looking for experienced **SDETs (Software Development Engineers in Test)** to build and execute automated regression testing for a complex observability and audit platform operating across multiple enterprise environments. This is a highly technical, hands-on automation role focused on validating **APIs, data and telemetry pipelines, distributed tracing, alerting, audit capabilities, infrastructure deployments, performance, and scalability**. This is not a traditional UI-focused QA automation position. You will develop automated regression suites, validate Infrastructure as Code (IaC) deployments, execute load and failure scenarios, investigate defects, and provide regression evidence throughout a sprint-based development lifecycle. The ideal candidate combines strong test automation and scripting skills with enough knowledge of **AWS, Terraform, OpenTelemetry, and distributed systems** to effectively validate complex infrastructure and observability capabilities. ### Responsibilities: - Design, build, maintain, and execute automated regression test suites. - Develop automated tests for log and metric ingestion pipelines. - Validate search and query functionality, accuracy, and latency. - Test distributed tracing accuracy and end-to-end telemetry flows. - Validate alert delivery, firing conditions, and routing behavior. - Develop automated tests for audit trail queries, integrity, and expected system behavior. - Validate Infrastructure as Code (IaC) deployments, including clean-state deployments, reproducibility, and zero-manual-step expectations. - Execute and help design load and scalability testing against defined performance targets. - Execute failure-injection scenarios and validate expected platform behavior. - Run regression testing across multiple versions and environments in parallel. - Identify, document, triage, and track defects against formal acceptance criteria. - Verify fixes and execute appropriate regression testing before quality sign-off. - Collaborate with the Test Architect and engineering teams to continuously improve regression coverage. - Maintain clear and reproducible automation code and testing documentation. - Provide regression evidence during sprint reviews and contribute to quality status reporting. - Work within Agile sprint cycles using formal acceptance criteria and Definition of Done (DoD). ### Requirements: - **4+ years of professional experience as an SDET, Test Automation Engineer, QA Automation Engineer, or similar technical testing role.** - Strong hands-on experience developing and maintaining automated test suites. - Strong API testing and automation experience. - Experience with scripting for technical validation and automation. - Experience with load and/or performance testing. - Working knowledge of cloud-based environments. - Experience testing complex backend, infrastructure, data pipeline, or distributed systems. - Experience working with formal acceptance criteria and Agile development processes. ### Must Have: - **4+ years of professional SDET or test automation experience.** - Strong hands-on test automation skills. - Strong **API testing and API automation** experience. - Experience developing automated regression suites. - Strong scripting skills for automation, pipeline validation, or log/data validation. - Experience with **load and performance testing tools**. - Experience testing backend, infrastructure-heavy, data-intensive, or distributed systems. - Working knowledge of **AWS** environments. - Working knowledge of **Terraform-deployed environments** and Infrastructure as Code concepts. - Working knowledge of **OpenTelemetry-based systems**. - Understanding of logs, metrics, telemetry, and distributed tracing concepts. - Experience validating data or telemetry pipelines. - Experience testing across multiple environments and/or product versions. - Experience with defect identification, triage, tracking, and fix verification. - Experience working with **Jira** or similar issue-tracking tools. - Experience working with formal acceptance criteria and **Definition of Done (DoD)**. ### Nice to Have: - Previous experience testing observability platforms. - Experience validating OpenTelemetry implementations. - Experience with log and metric ingestion testing. - Experience validating distributed tracing. - Experience testing alerting and notification workflows. - Experience validating audit trail integrity. - Experience with failure-injection or resilience testing. - Experience with high-volume data pipeline testing. - Experience with security-related regression testing. - Experience validating Infrastructure as Code deployments. - Experience testing ERP or complex enterprise platforms. - Experience working across multiple versions of the same enterprise application. - Experience with CI/CD-integrated automated regression suites.
