The Performance Engineering team delivers a seamless digital experience to Tesla customers, employees, suppliers, and robots by proactively optimizing systems to handle varying workloads. Their work enables highly-performant applications with end-to-end automated scalability as well as load tests with detailed metric analysis. The group also orchestrates code analysis utilizing instrumentation/profiling and other observability toolsets; they detect & resolve regressions, employing best practices to enhance application capability at large.
This engineer will be responsible for identifying bottlenecks and guiding critical system architecture/design solutions to maintain optimal application performance under heavy-load or high-traffic scenarios. Your contributions will directly improve efficiency, scalability, and end-user experience across multiple verticals — all of which explicitly impact Tesla's bottom line.
- Collaborate with developers to improve the efficiency of code, refactor algorithms, and implement optimizations (e.g., database query optimization, memory leaks, CPU-intensive processes)
- Perform deep-dive analysis into application code using profiling tools to identify and resolve inefficiencies
- Investigate & resolve performance degradation incidents through root cause analysis
- Use deep diagnostic tools and methods, such as network analysis, database profiling, and code debugging to identify issues
- Drive continuous improvement by addressing and resolving performance bottlenecks discovered during testing or in production
- Analyze logs and system metrics (CPU, memory, disk I/O, network, and database performance) to detect potential bottlenecks or slowdowns
- Measure critical metrics such as Response time, latency, throughput, and error rates across the Application , CDN and network infrastructure
- Design and execute performance tests such as load, stress, and endurance tests using tools like JMeter, Gatling, Vegeta, or k6
- Define performance benchmarks and Service Level Objectives (SLOs) for applications based on user requirements
- Create and maintain performance test plans, strategies, and reports to validate the system’s ability to scale under expected user loads
- Expertise in using the profiling tools (e.g., Dotnet-trace, Pprof, PySpy, JProfiler, VisualVM, YourKit, Perf) for application code analysis & performance bottleneck identification
- Experience with database indexing, query optimization, connection pooling, and caching strategies (MySQL, MSSQL)
- Deep understanding of cloud infrastructure & container orchestration platforms like Kubernetes or Docker
- Knowledge of CI/CD tools like Jenkins & GitHub for integrating performance testing into release pipeline
- Understanding of TCP/IP, HTTP/HTTPS , DNS, load balancing, and CDN technologies
- Strong experience with scripting languages like Python, Shell, Bash, or Groovy to automate performance testing & monitoring tasks
- Knowledge of JMeter, Gatling, LoadRunner, Vegeta, k6, BlazeMeter, or other load testing frameworks is a plus
