Senior SDET - Test Automation & Performance Engineering | Contract | Remote US
Tech HoldingRemote · Posted 14 days agoDescription
About us:
Working at Tech Holding isn't just a job, it's an opportunity to be a part of something bigger. We are a full-service consulting firm that was founded on the premise of delivering predictable outcomes and high-quality solutions to our clients. Our founders and team members have industry experience and have held senior positions in a wide variety of companies – from emerging startups to large Fortune 50 firms – and we have taken our combined experiences and developed a unique approach that is supported by the principles of deep expertise, integrity, transparency, and dependability.
The Role:
We are looking for a Senior SDET / Test Automation Engineer for a project based assignment to build the automated testing and release systems that ensure our products remain reliable as traffic, data volume, integrations, partners, and release velocity increase. This is a hands-on engineering role focused on test automation, API and integration testing, performance and scalability testing, and CI/CD quality gates within an AWS-based environment.
This is not a manual QA position. You will design and build reusable test infrastructure, automate critical product and partner workflows, create realistic performance scenarios, and provide engineering teams with clear evidence of whether a release is ready for production.
You will work closely with engineering teams and the Performance & Reliability Engineering Lead to ensure quality and scalability are built into the development lifecycle rather than treated as a final release checkpoint.
Key Responsibilities:
- Design and evolve the automated testing architecture across products and engineering teams
- Build and maintain automated API, integration, contract, end-to-end, regression, and UI tests where appropriate
- Develop reusable test frameworks, fixtures, synthetic data, mocks, and environment strategies
- Build automated testing for distributed services and integrations running within AWS environments
- Design and execute load, stress, spike, soak, scalability, degradation, and recovery tests
- Translate performance and capacity scenarios into repeatable automated test 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 enforceable quality and release gates
- Create automated release checks tied to quality, latency, reliability, and performance thresholds
- Establish practices for identifying, quarantining, diagnosing, and eliminating flaky tests
- Improve test observability and failure reporting so engineers can quickly understand and diagnose issues
- Build and maintain reliable 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 help reduce escaped defects, flaky tests, manual release effort, and regression risk
- Coach engineers on testability, automation, quality ownership, and defect-prevention practices
Required Skills:
- 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
Nice to have:
- Experience testing high-scale SaaS or distributed platforms
- Experience with AWS services supporting highly available or distributed applications
- Experience testing systems with significant traffic, concurrency, or availability requirements
- Experience with resilience, failure injection, dependency degradation, or recovery testing
- Experience with infrastructure-as-code and ephemeral or automated test environments
- Experience with security-adjacent testing, including permissions, authentication, authorization, isolation, and negative-path scenarios
- Identity, DNS, registry, or security domain experience
- Experience building quality or test platforms used across multiple engineering teams
What Success Looks Like
Within your first several months, you will have:
- Established a clear risk-based automation strategy across critical product and partner workflows
- Built reliable automated regression, API, integration, and contract test coverage
- Created repeatable performance and scalability tests for the platform's highest-risk journeys
- Established realistic test-data and environment strategies
- Integrated critical test suites directly into CI/CD pipelines
- Implemented measurable release gates tied to quality, latency, reliability, and performance thresholds
- Reduced flaky tests and improved the clarity and actionability of automated test failures
- Established performance trend reporting and repeatable load, soak, and failure-testing capabilities
- Reduced manual release validation and increased confidence in production readiness
- Helped establish shared quality ownership across engineering teams
