📋 Description

• Design and build scalable testing systems, platforms, and infrastructure that replicate real-world production conditions • Develop software and tooling to test application performance, reliability, scalability, and infrastructure behavior at high traffic volumes • Build and maintain load, performance, stress, and synthetic testing capabilities for applications serving millions of users globally • Create testing environments and processes that provide confidence that new code and infrastructure will scale successfully in production • Write high-quality code using TypeScript, Python, or similar languages to build testing tools, automation, and supporting systems • Design tests that identify performance bottlenecks related to latency, bandwidth, application speed, infrastructure capacity, and resource utilization • Integrate automated testing and quality validation into CI/CD pipelines and engineering workflows • Work with cloud-hosted applications and infrastructure across platforms such as AWS, Cloudflare, Google Cloud, or similar providers • Use Infrastructure as Code tools such as Terraform, Pulumi, or equivalent technologies to support repeatable and scalable testing environments • Partner closely with platform engineers to understand system architecture, production behavior, and infrastructure constraints • Analyze test results and production-like workloads to identify scalability risks before changes reach real-world traffic • Help establish the technical standards, systems, and processes for a new engineering-focused testing function

🎯 Requirements

• Strong professional software engineering experience with the ability to independently design, build, and maintain software systems • Strong coding skills in TypeScript, Python, or comparable modern programming languages • Experience building automated testing systems, engineering tooling, testing infrastructure, or similar software-driven quality solutions • Hands-on experience with load testing, performance testing, stress testing, synthetic testing, or large-scale application validation • Experience working with applications or platforms serving millions of users or visitors, ideally at multi-million or tens-of-millions scale • Experience working with cloud-hosted applications and infrastructure using AWS, Google Cloud, Cloudflare, or comparable platforms • Strong understanding of DevOps, platform engineering, infrastructure, scalability, and modern software deployment practices • Experience with CI/CD and integrating automated validation into continuous integration and deployment workflows • Experience with Infrastructure as Code using Terraform, Pulumi, or similar technologies • Strong understanding of application performance concepts including latency, bandwidth, throughput, scalability, reliability, and infrastructure optimization • Ability to independently investigate complex technical problems and build solutions with limited oversight • Strong written and spoken English with the ability to communicate technical decisions and collaborate effectively with a distributed engineering team • Preferred: Experience supporting globally distributed applications serving tens of millions of monthly visitors • Preferred: Experience with high-traffic e-commerce platforms or other large-scale consumer-facing applications • Preferred: Experience working with custom or internally built platforms rather than primarily testing third-party or off-the-shelf software • Preferred: Experience optimizing applications or infrastructure where speed, latency, bandwidth, and infrastructure cost are critical considerations • Preferred: Experience building testing infrastructure or frameworks from the ground up rather than primarily working within established QA systems • Preferred: Background in DevOps, Site Reliability Engineering, Platform Engineering, performance engineering, or infrastructure engineering • Preferred: Experience working in fast-moving startup or lean engineering environments where engineers have significant ownership and autonomy
