The posting

As a Senior Software Development Engineer in Test (SDET), you will build the systems, infrastructure, and tooling that enable a high-scale technology platform to test applications under conditions that closely replicate the real world.

This is an engineering role, not a traditional manual QA position. You will write production-quality code and build testing platforms capable of validating performance, reliability, and scalability across applications serving millions of users globally. A key challenge will be creating environments and systems that can simulate traffic and workloads that are difficult to reproduce through conventional testing environments.

You will work closely with platform engineers and the broader engineering organization to give the team confidence that new code and infrastructure will perform reliably when deployed at scale. This role is ideal for an engineer who enjoys solving complex infrastructure, performance, and reliability problems and is comfortable independently designing solutions from the ground up.

Responsibilities

  • 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
  • Experience with high-traffic e-commerce platforms or other large-scale consumer-facing applications
  • Experience working with custom or internally built platforms rather than primarily testing third-party or off-the-shelf software
  • Experience optimizing applications or infrastructure where speed, latency, bandwidth, and infrastructure cost are critical considerations
  • Experience building testing infrastructure or frameworks from the ground up rather than primarily working within established QA systems
  • Background in DevOps, Site Reliability Engineering, Platform Engineering, performance engineering, or infrastructure engineering
  • Experience working in fast-moving startup or lean engineering environments where engineers have significant ownership and autonomy

Benefits

  • Salary: $5,000 to $6,000 USD per month
  • PTO: 15 days
  • Holidays: Local or US holidays

Why it works

3×

more interviews than doing it yourself with ChatGPT.

ChatGPT writes a CV and never learns what happened to it. We see every reply. For each CV we know:

  • How it was written, and how the review scored it
  • When we applied, and how long after the posting went up
  • Which posting, which company, which city
  • Who got the interview, and who heard nothing

That is how we know which CVs get called.
