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. Experi
