Role: Senior QA Engineer - Functional & Automation
Location: Princeton NJ
Salary: $115k PA
Role: 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.
Required Skills
- 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.
- Jenkins/CI-CD, Maven, Git.
- Strong analytical mindset; able to work Consultantly through intermittent, ambiguous failures.
