The role requires strong hands-on expertise in JMeter and complementary performance-testing tools, test scripting, workload modelling, statistical analysis of results, and evidence-based root-cause analysis across application, JVM, database, search, and infrastructure layers. You will partner with development and infrastructure colleagues to translate findings into prioritized recommendations and verified improvements.\n\nKey Responsibilities:\nDesign realistic load, stress, spike, endurance, scalability, and capacity simulations based on user behaviour, transaction flows, concurrency, data volumes, pacing, and production-like workload distributions.\nDevelop and maintain reusable JMeter frameworks and scripts for web applications and APIs, including correlation, parameterization, dynamic test data, assertions, distributed execution, and automated result collection. Use LoadRunner, Gatling, k6, or other tools where appropriate.\nDefine workload models, baselines, SLAs, and acceptance criteria with stakeholders.\nAnalyze response-time distributions and percentiles, throughput, errors, variability, saturation points, and resource trends; distinguish repeatable patterns from noise, outliers, and environmental variation.\nDiagnose Java/JVM issues using JFR, heap and thread dumps, GC logs, Eclipse MAT, jcmd, and related tools, including memory leaks, OOM errors, high CPU, thread contention, and connection-pool bottlenecks.\nAnalyze and tune performance across JBoss/WildFly, Tomcat, SQL Server, REST APIs, and OpenSearch/Elasticsearch in collaboration with development and infrastructure teams.\nCorrelate transaction timings, logs, traces, diagnostics, database behaviour, and cloud/infrastructure metrics to identify and quantify root causes.\nForm and test hypotheses, recommend prioritized improvements, and rerun controlled tests to verify benefits and prevent regressions.\nIntegrate repeatable performance checks into CI/CD pipelines and maintain controlled environments, baselines, and versioned test assets.\nPlan investigations independently, estimate effort, manage dependencies and risks, validate test-environment and load-generator constraints, and document reproducible findings.\nUse approved AI tools where appropriate for scripting, diagnostics, and reporting; validate outputs and protect proprietary and customer data.\n\nRequired Skills:\n8+ years of testing experience, including at least 5 years of hands-on performance testing and engineering, with independent delivery of complex investigations.\nAdvanced JMeter experience designing, scripting, debugging, executing, and maintaining realistic simulations for enterprise web applications and APIs, including distributed load generation, correlation, parameterization, dynamic test data, workload modelling, and automated result collection.\nDemonstrated ability to interpret percentiles, distributions, throughput, errors, variability, saturation behaviour, and resource correlations; distinguish meaningful findings from noise; and communicate evidence-based root causes, capacity limits, and recommendations.\nHands-on Java/JVM performance diagnosis using profiling data, JFR, heap and thread dumps, GC logs, Eclipse MAT, jcmd, or comparable tools.\nPerformance-analysis experience across JBoss/WildFly or Tomcat, SQL Server, and REST APIs.\nExperience with monitoring and APM tools such as Grafana, Prometheus, Dynatrace, AppDynamics, or Datadog for cross-layer correlation and root-cause analysis.\nExperience with AWS or comparable cloud infrastructure, Linux and Windows, Git, and CI/CD pipelines for repeatable performance-test execution.\nAbility to use Python, PowerShell, Bash, Java, or similar languages for test-data generation, execution automation, result processing, statistical analysis, and repeatable reporting.\n\nPreferred Skills:\nExperience with OpenSearch/Elasticsearch performance analysis.\nExperience with LoadRunner, Gatling, or k6 in addition to JMeter.\nEffective use of AI-assisted tools for performance scripting, analysis, or diagnostics, with critical validation of outputs.\nSkills\nCapacity Testing, JMeter, JVM, Java, Load Testing, Performance Testing, Scalability Testing, Stress Testing","description_format":"text","description_chars":4528,"description_truncated":false,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":[],"hiring_locations":[],"hiring_excludes":[],"relocation_offered":false,"industries":["Packaging & Labeling"],"lifecycle":[{"event":"open","at":"2026-11-14T15:36:00Z"}],"visa":[],"liveness":{"score":86,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.86,"p_room":1,"age_days":0,"expected_fill_days":33,"reasons":["seen:0","win:early"],"computed_at":"2026-11-14T18:21:27Z"},"pay":null,"html_url":"https://alion.io/job/esko-senior-performance-test-specialist","json_url":"https://alion.io/job/esko-senior-performance-test-specialist.json","meta":{"generated_at":"2026-11-14T18:21:27Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":21770,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-11-15T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.1,"usd":0.01,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":96374},"rest":"https://alion.io/mcp/rest/get_company?id=96374"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fesko-senior-performance-test-specialist"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"free","price":{"credits":0,"usd":0},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fesko-senior-performance-test-specialist"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.1,"usd":0.01},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fesko-senior-performance-test-specialist"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/esko-senior-performance-test-specialist\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fesko-senior-performance-test-specialist"}],"agent":{"mcp":"https://alion.io/mcp/jobs","mcp_open":"https://alion.io/mcp/open","next":[{"tool":"get_job","arguments":{"id":4315537}},{"tool":"search_jobs","arguments":{"company":"esko.com","detail":"compact"}},{"tool":"match_people","arguments":{"job_id":4315537},"note":"people open to offers who fit this vacancy"}],"note":"The same data through MCP tools: https://alion.io/mcp/open needs no sign-in (compact searches, postings, people);
