QA Automation Engineer

Ethereum Technologies; Princeton (NJ); On-site; USD 90,000 - 120,000; Full time

Job summary

Ethereum Technologies in Princeton, NJ seeks a hands-on QA Automation Engineer to own the AWS-hosted regression framework and drive improvements across UI, API, and service layers. You will fix framework and infrastructure issues, not just run tests, and collaborate to harden provisioning, secret management, and CI/CD integration.

The role requires 8+ years of QA experience, strong Java, Selenium and Cucumber/BDD skills, and proven AWS automation expertise.

Qualifications

• 8+ years QA across functional and automation.
• Strong Java — able to write and debug framework code, not just scripts.
• Selenium, Cucumber/BDD, solid SQL.
• Proven experience debugging, fixing and improving automation frameworks in AWS (EC2/ECS, S3, SQS, RDS, CloudWatch, IAM).
• Track record of measurably reducing regression runtime and flakiness.
• Strong analytical mindset; able to work independently through intermittent, ambiguous failures.

Responsibilities

• Design and execute functional test cases; validate data directly via SQL.
• Build, extend and refactor the core automation framework (UI, API and service layers).
• Own the AWS automation framework — permanently fix cloud failure modes (container restarts, load balancer timeouts, DB connectivity and connection-pool exhaustion, S3/SQS integration, IAM/credential expiry, config drift).
• Harden environment provisioning, seeding, teardown and secrets management so runs start from a known-good baseline.
• Implement resilience in the framework — retry with backoff, health checks and readiness gates, graceful handling of transient cloud failures.
• Improve the end-to-end AWS regression process — reduce runtime via parallelisation and sharding, drive down flaky tests against measurable targets, and add failure trend dashboards and automatic artefact capture.
• Analyse logs and stack traces to isolate root cause; classify failures as product defect, script defect, test data, environment or timing.
• Integrate and maintain suites in CI/CD; partner with DevOps and Development to clear infrastructure blockers and communicate risk.

Job Description

Hands-on QA Engineer covering both functional testing and automation, with ownership of the AWS-hosted regression framework and process — engineering fixes at framework and infrastructure level, not just running tests and analysing results.

Key Responsibilities

• Design and execute functional test cases; validate data directly via SQL.
• Build, extend and refactor the core automation framework (UI, API and service layers).
• Own the AWS automation framework — permanently fix cloud failure modes (container restarts, load balancer timeouts, DB connectivity and connection-pool exhaustion, S3/SQS integration, IAM/credential expiry, config drift) rather than re-running or masking them.
• Harden environment provisioning, seeding, teardown and secrets management so runs start from a known-good baseline.
• Implement resilience in the framework — retry with backoff, health checks and readiness gates, graceful handling of transient cloud failures.
• Improve the end-to-end AWS regression process — reduce runtime via parallelisation and sharding, drive down flaky tests against measurable targets, and add failure trend dashboards and automatic artefact capture.
• Analyse logs and stack traces to isolate root cause; classify failures as product defect, script defect, test data, environment or timing.
• Integrate and maintain suites in CI/CD; partner with DevOps and Development to clear infrastructure blockers and communicate risk.
