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
- Improve system confidence byvalidatingreal-world scenarios, edge cases, and degradation paths
- Advocate for engineering practices that improveoperability and system robustness
- Drive reliability validation efforts for complex distributed systems, including resilience, failover, and recovery testing
- Influence system architecture by advocating for reliability, observability, and operability best practices
- Use production telemetry and incident learnings to continuously improve validation and performance strategies
Required Qualifications
- Bachelor's degree in Computer Science, Engineering, or related field
- 6-8years of experiencein software engineering, SDET,SREor related roles
- Strong programming skills (Java, Python, C#, or JavaScript) with ability to build production-quality code
- Proven experience designing and implementing scalable automation frameworks or validation platforms
- Hands-on experience withAPI and distributed systems testing
- Experience withperformance testing tools(e.g., k6, JMeter, Gatling)
- Familiarity withCI/CD systemsand modern development workflows
- Solid understanding ofsystem design, scalability, and performance fundamentals
Preferred Qualifications
- Experience inProduction Engineering, SRE, or infrastructure-focused teams
- Familiarity withmicroservices and cloud-native architectures
- Experience withobservability tools(e.g., metrics, logs, tracing-Grafana, Prometheus, Datadog)
- Knowledge ofcontainers and orchestration(Docker, Kubernetes)
- Exposure toresilience testing, chaos engineering, or fault injection
- Experience modelingproduction traffic patterns or capacity planning
Key Skills
- Strong systems-thinking mindset with deep understanding of distributed system behavior under load and failure conditions
- Ability to lead complex technical initiatives with minimal direction
- Strong technical judgment and ability to balance reliability, performance, and engineering velocity
- Experience influencing engineering teams through technical leadership and collaboration
- Exceptional troubleshooting and root-cause analysis skills
What Success Looks Like
- Systems arevalidatedagainstrealistic production scenarios, not just functional correctness
- Improved system reliability throughproactive validation of edge cases and failure modes
- Strong contribution to a culture ofengineering ownership of quality and performance
- Performance and scalability risks areidentifiedand mitigated early in the development lifecycle
- Validation frameworks become trusted engineering tools used across teams
- Reliability, performance, and production-readiness standards are consistently met across supported services
- Engineering teams proactivelyleveragevalidation and performance insights to improve system design
