You’ll work closely with Engineering, DevOps, and Product teams to deliver a high-performing and seamless experience to our growing customer base.

Role and Responsibilities

• Design, develop, and execute performance, load, stress, and scalability tests for our SaaS platform's web applications, APIs, and backend microservices.
• Build and maintain performance testing frameworks using tools such as JMeter, Gatling, k6, or similar.
• Create realistic load simulations based on usage patterns of SaaS customers across multiple regions and tenants.
• Analyze performance test results and system metrics (CPU, memory, I/O, latency, throughput) using tools like Grafana, New Relic, or Datadog.
• Work with DevOps to test in production-like environments and automate performance testing in CI/CD pipelines.
• Collaborate with backend and infrastructure teams to identify performance bottlenecks, optimize configurations, and inform capacity planning.
• Monitor and validate adherence to SLAs and SLOs across services, particularly during scale-up events or product launches.
• Support engineering teams by recommending optimizations and tuning strategies across application tiers (app, database, cache, etc.).
• Provide detailed, data-driven reports with insights and recommendations for technical and product stakeholders.
• Advocate for performance best practices in design, implementation, and infrastructure decisions.
• Continuously improve tooling, automation, and test coverage for performance testing at scale.

• Experience with RESTful API testing and web application profiling.
• Ability to work cross-functionally with engineering, SRE, and product teams in a fast-paced, agile environment.
• Strong analytical and communication skills, with the ability to present performance results and impact to both technical and non-technical audiences.

Bonus Skills

• Experience in SaaS-specific performance concerns: multi-tenancy, region-based scaling, background job processing.
• Familiarity with caching layers, CDN behavior, or real-time data streaming.
• Knowledge of performance testing in CI/CD using tools like Jenkins
