Job description

Overview

Production Engineering is seeking aSr,Software Development Engineer in Test (SDET)to drivesystem reliability, scalability, and performance validationthrough automation and engineering rigor.

This role goes beyond traditional testing-you will build systems and frameworks thatvalidateproduction readiness, enforceperformance and reliability standards, and ensure services behave correctly under real-world conditions.

You willoperateat the intersection of software engineering, performance engineering, and system reliability, driving the strategy, architecture, and implementation of validation frameworks that ensure services are reliable, scalable, andproduction-ready.

Key Responsibilities

System Validation & Test Automation

  • Build andmaintainautomated validation frameworksfor APIs, distributed systems, and critical service workflows
  • Developintegration and end-to-end validation suitesthat reflect real production use cases
  • Ensure validation isfully integrated into CI/CD pipelineswith meaningful quality gates
  • Design systems and tooling that improvetestability, observability, and diagnosability
  • Drive improvements in validation coverage and overall system confidence through data-driven analysis and risk-based prioritization
  • Drive reduction of flaky or low-signal tests to ensurehigh signal-to-noise automation

Performance Engineering

  • Design and implementload, stress, and endurance testing strategiesfor distributed systems
  • Build andmaintainperformance test frameworks and workloadsthat model real traffic patterns
  • Define andmaintainperformance baselines, SLAs/SLOs, and capacity models that guide engineering and operational decisions
  • Analyze system behavior under load toidentifybottlenecks, resource contention, and scaling limits
  • Drive performance improvements by working directly in code, configuration, and infrastructure
  • Integratecontinuous performance validationinto CI/CD and pre-production workflows

Production Engineering & Reliability

  • Ensure services meetproduction readiness standards, including reliability, scalability, and observability
