EngineeringQa Engineer

We are looking for an experienced Senior Software Development Engineer in Test (SDET) specializing in performance testing to strengthen the quality, scalability, and reliability of a large-scale, cloud-based platform. In this role, you will lead performance engineering initiatives, establish testing standards, and ensure critical services remain resilient under demanding workloads. You will design and implement automated performance testing frameworks, define performance benchmarks, and integrate regression testing into CI/CD pipelines. Working across distributed systems, microservices, APIs, databases, and cloud infrastructure, you will identify bottlenecks and drive meaningful improvements. You will collaborate closely with engineering, DevOps, and infrastructure teams to translate performance insights into actionable technical solutions. This is an opportunity to take technical ownership, mentor other engineers, and influence performance engineering practices within a fast-paced, globally distributed environment.

Performance Strategy and Benchmarking:

Establish performance baselines for critical services, defining Service Level Indicators (SLIs), Service Level Objectives (SLOs), and measurable targets for latency, throughput, and error rates.

Develop realistic workload models based on production traffic patterns and actual customer behavior.

Define performance testing strategies that support scalability, reliability, and continuous improvement across the platform.

Conduct capacity planning to ensure systems can handle increasing traffic volumes and anticipated peak-demand events.

Performance Testing Framework Development:

Design, build, and maintain a shared performance testing framework that product engineering and SDET teams can use consistently.

Create production-like testing environments using Kubernetes and cloud infrastructure, including appropriate test data and configurations.

Evaluate emerging performance testing tools and technologies through proof-of-concept initiatives and recommend suitable solutions.

Establish reusable testing standards and best practices to improve consistency and efficiency across engineering teams.

Automated Testing and Continuous Integration:

Integrate automated performance regression testing into CI/CD pipelines to identify performance degradation before production releases.

Establish performance thresholds and automated pass/fail criteria to maintain service quality.

Develop performance trend reports and monitoring mechanisms to identify emerging issues and track improvements over time.

Execute load, stress, soak, and spike testing to evaluate system behavior under different operating conditions.

Performance Analysis and Optimization:

Investigate and identify performance bottlenecks across APIs, databases, message queues, and frontend applications.

Conduct root cause analysis using distributed tracing, metrics, logs, and profiling tools.

Collaborate with development, DevOps, and infrastructure teams to resolve performance issues and improve system efficiency.

Translate complex performance metrics into clear engineering recommendations and influence technical decisions across teams.

Evaluate distributed systems behavior, concurrency challenges, rate limiting, caching, and other factors affecting application performance.

Technical Leadership and Mentorship:

Take ownership of performance engineering initiatives and drive continuous improvements in testing methodologies.

Mentor junior engineers and support their technical development through knowledge sharing, guidance, and code reviews.

Contribute to capability-building initiatives and establish engineering practices that raise performance and reliability standards across the organization.

Work collaboratively with cross-functional teams to ensure performance considerations are integrated throughout the software development lifecycle.

Strong analytical and problem-solving skills, with the ability to interpret performance results and turn findings into practical engineering recommendations.

Excellent collaboration and communication skills, enabling effective partnership with software developers, DevOps engineers, infrastructure teams, and other stakeholders.

Ability to take technical ownership, work independently, manage priorities, and contribute effectively in a fast-paced engineering environment.

Experience mentoring junior engineers and promoting engineering best practices is highly valued.

Experience with runtime profiling and thread or heap analysis for JVM or Node.js applications, including garbage collection behavior and event-loop latency.

Knowledge of frontend performance optimization, including Core Web Vitals, Lighthouse, and Real User Monitoring (RUM).

Experience using AI-assisted tools to improve test design, automate performance analysis, or interpret testing results.

Familiarity with NoSQL databases, search technologies, and message brokers operating at scale.

Experience with chaos engineering, resilience testing, and safe production testing techniques, including canary releases and shadow traffic.
