Staff SDET Engineer

We are searching for a Staff Software Development Engineer in Test (SDET) to join the Aviatrix Engineering Productivity (EngProd) 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 Benefits Stock options for all full-time employees World-class coverage - we pay 100% of employee premiums and 88% of the family cost 401K Parental Leave (up to 12 weeks) Flexible Vacation Up to $1000 education reimbursement anually Proven ability to work independently and drive projects from design through delivery with minimal supervisionProficient in leveraging AI-powered tools (e.g., GitHub Copilot, LLM-based assistants) to improve test generation, infrastructure automation, and engineering productivityBachelor’s, Master’s, or PhD in Computer Science or a related fieldStrong coding skills in Python and/or GolangDeep understanding of cloud infrastructure concepts, including networking, gateway architectures, VPCs, and CSP account structures (AWS, Azure, GCP, or OCI)6+ years of experience in software development or test engineering, with strong emphasis on infrastructure, scale testing, or platform engineeringProficiency with Terraform for building and maintaining regression and scale test infrastructureExperience with CI/CD pipelines, GitHub Actions, Docker, and KubernetesHands‑on experience designing and managing test environments at scale using cloud platforms and infrastructure-as-codeA technical leader who can influence platform and test strategy, mentor others, and drive cross‑team alignment without needing formal authorityA systems thinker who can design infrastructure that doesn’t yet exist and drive it to productionSomeone with a scale‑first mindset — you understand how systems behave under load and know how to build environments that expose those behaviors reliablyA strong collaborator who can translate complex domain requirements from networking and platform engineers into robust playground infrastructure and benchmark toolingA builder who takes full ownership — from problem definition through design, implementation, and ongoing operationsPrior work on hybrid or multi‑cloud infrastructure environmentsExperience mentoring junior engineers or providing technical leadership on infrastructure projectsFamiliarity with benchmark testing methodology — designing repeatable benchmarks, establishing baselines, and detecting regressions in processing time or memory usageExperience building large-scale simulation or emulation environments (e.g., fake/simulated gateway fleets, network topology emulation)Experience with observability and monitoring tools such as Grafana, Prometheus, or Datadog for environment health and test result visualization #J-18808-Ljbffr Aviatrix Systems
