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.
