Tesla
Sr. Software Engineer, Performance Engineering
Tesla, Austin, Texas, us, 78716
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.
Responsibilities
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 inefficienciesInvestigate & resolve performance degradation incidents through root cause analysisUse deep diagnostic tools and methods, such as network analysis, database profiling, and code debugging to identify issuesDrive continuous improvement by addressing and resolving performance bottlenecks discovered during testing or in productionAnalyze logs and system metrics (CPU, memory, disk I/O, network, and database performance) to detect potential bottlenecks or slowdownsMeasure critical metrics such as Response time, latency, throughput, and error rates across the Application , CDN and network infrastructureDesign and execute performance tests such as load, stress, and endurance tests using tools like JMeter, Gatling, Vegeta, or k6Define performance benchmarks and Service Level Objectives (SLOs) for applications based on user requirementsCreate and maintain performance test plans, strategies, and reports to validate the system's ability to scale under expected user loadsRequirements
Expertise in using the profiling tools (e.g., Dotnet-trace, Pprof, PySpy, JProfiler, VisualVM, YourKit, Perf) for application code analysis & performance bottleneck identificationExperience with database indexing, query optimization, connection pooling, and caching strategies (MySQL, MSSQL)Deep understanding of cloud infrastructure & container orchestration platforms like Kubernetes or DockerKnowledge of CI/CD tools like Jenkins & GitHub for integrating performance testing into release pipelineUnderstanding of TCP/IP, HTTP/HTTPS , DNS, load balancing, and CDN technologiesStrong experience with scripting languages like Python, Shell, Bash, or Groovy to automate performance testing & monitoring tasksKnowledge of JMeter, Gatling, LoadRunner, Vegeta, k6, BlazeMeter, or other load testing frameworks is a plusCompensation and BenefitsBenefits
