SDET Engineer

Requirements

• 6+ years of experience in software development or test engineering, with strong emphasis on infrastructure, scale testing, or platform engineering
• Bachelor's, Master's, or PhD in Computer Science or a related field
• Strong coding skills in Python and/or Golang
• Deep understanding of cloud infrastructure concepts, including networking, gateway architectures, VPCs, and CSP account structures (AWS, Azure, GCP, or OCI)
• Hands-on experience designing and managing test environments at scale using cloud platforms and infrastructure-as-code
• Proficiency with Terraform for building and maintaining regression and scale test infrastructure
• Experience with CI/CD pipelines, Git Hub Actions, Docker, and Kubernetes
• Proven ability to work independently and drive projects from design through delivery with minimal supervision
• Proficient in leveraging AI-powered tools (Git Hub Copilot, LLM-based assistants) to improve test generation, infrastructure automation, and engineering productivity
• (Desirable) Experience building large-scale simulation or emulation environments (e.g., fake/simulated gateway fleets, network topology emulation)
• (Desirable) Familiarity with benchmark testing methodology — designing repeatable benchmarks, establishing baselines, and detecting regressions in processing time or memory usage
• (Desirable) Experience with observability and monitoring tools such as Grafana, Prometheus, or Datadog for environment health and test result visualization
• (Desirable) Prior work on hybrid or multi-cloud infrastructure environments
• (Desirable) Experience mentoring junior engineers or providing technical leadership on infrastructure projects
• A systems thinker who can design infrastructure that doesn't yet exist and drive it to production
• Someone with a scale-first mindset — you understand how systems behave under load and know how to build environments that expose those behaviors reliably
• A technical leader who can influence platform and test strategy, mentor others, and drive cross-team alignment without needing formal authority
• A builder who takes full ownership — from problem definition through design, implementation, and ongoing operations
• A strong collaborator who can translate complex domain requirements from networking and platform engineers into robust playground infrastructure and benchmark tooling

• We are searching for a Staff Software Development Engineer in Test (SDET) to join the Aviatrix Engineering Productivity (Eng Prod) Integration Playground team
• In this role, you will own the design, build-out, and ongoing evolution of the Platform and Hybrid Scale Integration Playground — a critical environment that enables early-stage validation, scale testing, and infrastructure experimentation across the engineering organization
• This is a high-impact, infrastructure-forward role at the intersection of platform engineering and test infrastructure
• You will drive the development of scale testing capabilities that don't yet exist and establish shared playground infrastructure that the broader engineering organization depends on
• You will work closely with scale automation leads and domain experts across Networking, Platform, and the Engineering Release & Test (ERT) team, and will mentor junior engineers on the team
• Own the design, implementation, and ongoing improvement of the Platform and Hybrid Scale Integration Playground — including infra provisioning, test tooling, and environment lifecycle management
• Build and scale hybrid scale test infrastructure to support large-scale simulation environments with thousands of simulated gateways
• Develop benchmark test suites for operations known to cause problems at scale, ensuring regressions are detected early in the release cycle
• Design and maintain Terraform-based infrastructure for scale and platform playground environments, ensuring reliability and reproducibility across releases
• Identify gaps in test coverage for scale and platform features and drive improvements through new tooling or enhanced test strategies
• Partner with cross-functional teams — including Networking, Platform, Security, and ERT — to understand domain requirements and translate them into playground infrastructure and test designs
• Mentor engineers on the team; serve as a technical resource and set standards for test design, infrastructure quality, and best practices
• Lead test design and planning for platform and hybrid scale features, managing timelines and driving execution to completion
• Participate in code reviews, on-call rotations, and interview processes
