Job Description

Job Title: Lead Performance Engineer (Cloud-Native SaaS Platform) Location: Nashik / Pune Experience Level: Senior (710 Years Relevant Experience in Performance Engineering) Reports To: QE Manager --- A. Position Overview We are seeking a highly experienced and technically strong Lead Performance Engineer to design, implement, and govern the performance engineering practices across our multi-product, cloud-native SaaS platform. This role demands expertise in Frontend, Backend, Microservices, and Kubernetes-based architectures — with a clear focus on performance-first principles across all layers of the tech stack. The ideal candidate will own end-to-end performance strategy for the platform, mentor embedded testers across product lines, and drive a robust DevPerfOps culture aligned with modern cloud practices. --- B. Key Responsibilities 1. Performance Strategy and Governance Define and implement a centralized performance engineering strategy Develop performance testing frameworks and reusable assets for Frontend (UI), Backend (APIs/DB), and Microservices (Containerized Apps). Establish baseline KPIs (latency, throughput, scalability) aligned with business SLAs. 2. Test Design and Execution Architect and automate performance tests for Web Applications, Microservices APIs, and Database Systems. Execute Load, Stress, Spike, Soak, and Scalability testing across pre-production and production-like environments. Simulate real-world user load scenarios including multi-region, multi-browser patterns. 3. Cloud-Native Performance Engineering Drive performance validation on Azure cloud infrastructure with deep knowledge of Kubernetes, AKS (Azure Kubernetes Service), Docker containers. Optimize resource configurations (pods, autoscaling, ingress rules) to ensure resilient, high-performing clusters. Collaborate with DevOps to fine-tune container orchestration, networking, caching layers (Redis, CDN), and database sharding. 4. DevPerfOps and Observability Integrate performance validation into CI/CD pipelines using Azure DevOps. Leverage AppInsights, Grafana, Prometheus for live telemetry, trend analysis, and early performance risk detection. Establish automated alerts and feedback loops for performance degradations post-deployment. 5. Cross-Functional Collaboration Partner with Architects, Dev Leads, and Infra teams to triage system-level bottlenecks. Conduct deep-dive root cause analyses on API slowdowns, memory leaks, DB deadlocks, UI rendering lags, etc. Present performance findings, risk assessments, and optimization plans to leadership teams. 6. Mentorship and Scaling Mentor PL-based testers and interns in performance engineering techniques and tooling. Drive workshops and brown-bag sessions to scale performance-first culture across scrum teams. --- C. Required Skills & Experience A. Core Technical Expertise: Minimum 7+ years hands-on experience in performance engineering roles. Strong expertise in K6 (TypeScript scripting), JMeter, Postman for frontend and backend performance testing. Deep understanding of Microservices architecture, Kubernetes (AKS preferred), container networking, and service meshes. Solid experience in Azure Cloud or equivalent cloud platforms. Proficiency with CI/CD pipelines (Azure DevOps preferred) and scripting (JavaScript/TypeScript, Bash). B. Performance Tuning and Analysis: Proven track record of identifying and tuning performance bottlenecks across applications, APIs, databases, and cloud infra. Expertise in resource profiling, memory management, thread dumps analysis, and latency optimization. C. Observability and Monitoring: Experience with telemetry tools like AppInsights, Grafana, Prometheus, Kibana, etc. Strong grasp of setting up performance dashboards, alerts, and trend analysis mechanisms. --- D. Preferred Qualifications Bachelor’s or Master’s degree in Computer Science, Engineering, or a related field. Certifications in performance testing (e.g., CPPT, CSTP), cloud certifications (Azure/AWS), Kubernetes administration (CKA/CKAD) are highly desirable. Familiarity with mobile app performance testing and frontend tools like Lighthouse, WebPageTest is a plus.
