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 experie
