Job Description
Senior SDET building AWS test automation, API testing, and performance systems for Tech Holding’s consulting projects. Establishing CI/CD quality gates and production-readiness evidence.
Responsibilities:
- Design and evolve automated testing architecture across products and engineering teams
- Build and maintain automated API, integration, contract, end-to-end, regression, and appropriate UI tests
- Develop reusable test frameworks, fixtures, synthetic data, mocks, and environment strategies
- Build automated testing for distributed services and integrations in AWS environments
- Design and execute load, stress, spike, soak, scalability, degradation, and recovery tests
- Translate performance and capacity scenarios into repeatable automated suites with measurable pass/fail thresholds
- Model realistic workloads, concurrency levels, traffic patterns, data volumes, and dependency behavior
- Integrate automated suites into CI/CD pipelines and establish quality and release gates
- Create automated release checks tied to quality, latency, reliability, and performance thresholds
- Identify, quarantine, diagnose, and eliminate flaky tests
- Improve test observability and failure reporting
- Build and maintain test-data and test-environment strategies
- Debug failures across APIs, services, databases, infrastructure, and external integrations
- Partner with Performance & Reliability Engineering to validate scalability assumptions and production readiness
- Partner with Security Engineering on permissions, isolation, negative-path, and abuse-related test scenarios
- Track testing trends and reduce escaped defects, flaky tests, manual release effort, and regression risk
- Coach engineers on testability, automation, quality ownership, and defect prevention
Requirements:
- Strong experience as an SDET, Software Engineer in Test, Test Automation Engineer, Quality Engineer, or similar engineering-focused testing role
- Strong software development and test automation skills
- Experience testing APIs, distributed services, integrations, and cloud-based applications
- Hands-on experience working within AWS environments
- Strong experience building automated API and integration test frameworks
- Hands-on performance and scalability testing experience using tools such as k6, Gatling, Locust, JMeter, or equivalent
- Experience designing realistic performance workloads rather than simply executing predefined load tests
- Experience with load, stress, spike, soak, and scalability testing
- Strong experience integrating automated tests into CI/CD pipelines
- Experience establishing automated quality gates and release criteria
- Experience with contract testing and testing across service boundaries
- Strong understanding of test-data management, synthetic data, fixtures, mocks, and environment reliability
- Experience using logs, metrics, traces, and other observability tools to diagnose test and system failures
- Strong debugging skills across applications, APIs, infrastructure, databases, and integrations
- Experience identifying and reducing flaky or unreliable automated tests
- Ability to influence engineering teams and promote shared ownership of quality without becoming a centralized testing bottleneck
Benefits:
- Equal Opportunity Employer committed to fostering a diverse and inclusive workplace
- Application process accommodation available through HR
