Overview:
The Senior Performance Engineer serves as a senior technical contributor and domain specialist responsible for defining, engineering, and leading enterprise performance testing solutions that validate the scalability, reliability, resiliency, and production readiness of complex applications, services, and platforms. This role provides technical leadership across multiple initiatives, identifies systemic performance risk, establishes reusable standards and frameworks, and delivers data-driven recommendations that influence architecture, capacity, and release decisions. The role partners with application teams, architects, infrastructure, database, middleware, cloud, cybersecurity, vendors, and business stakeholders while mentoring engineers and advancing shift-left performance engineering practices.
Primary Responsibilities:
•
Lead performance engineering strategy, planning, execution, analysis, and reporting for complex, high-risk, or enterprise-scale initiatives across the Software Development Lifecycle (SDLC)
•
Design and implement performance test strategies, workload models, test frameworks, and validation approaches for web, API, mobile, cloud, containerized, and distributed applications
•
Engineer and maintain advanced performance test assets using OpenText Core Performance Engineering (LoadRunner Cloud), LoadRunner Professional/VuGen, JMeter, BlazeMeter, and related tooling
•
Develop robust automated performance test scripts in C and other applicable languages, including correlation, parameterization, reusable functions, error handling, data management, and validation logic
•
Lead load, stress, endurance, volume, scalability, resiliency, failover, and capacity testing to evaluate application behavior under realistic and peak business demand
•
Use Dynatrace and other observability tools to correlate application, infrastructure, database, network, and user-experience metrics; identify bottlenecks and guide root-cause analysis
•
Review application architectures, technical designs, infrastructure changes, migration plans, release scope, and nonfunctional requirements to identify performance risk and recommend mitigation before implementation
•
Define test objectives, workload assumptions, success criteria, entry and exit criteria, dependencies, constraints, and production-readiness recommendations
•
Provide authoritative technical guidance to application teams, architects, infrastructure partners, project leaders, and vendors on performance risk, remediation options, and release decisions
•
Create and maintain reusable performance engineering standards, scripting practices, test-plan expectations, analysis methods, reporting templates, readiness criteria, and governance controls
•
Advance shift-left performance testing by mentoring Software Engineers and Performance Engineers in JMeter, LoadRunner, test design, scripting, analysis, troubleshooting, and CI/CD integration
•
Coordinate technical activities with vendors and platform teams, including OpenText, BlazeMeter, Dynatrace, and application vendors, to resolve complex tooling, testing, and product-performance issues
•
Lead troubleshooting of complex production and pre-production performance issues by reproducing workload conditions, analyzing telemetry, and validating corrective actions
•
Support enterprise capacity planning by translating business volumes and growth assumptions into workload models, scalability findings, resource considerations, and risk-based recommendations
•
Identify opportunities to improve performance engineering efficiency through automation, reusable assets, modern tooling, cloud capabilities, and continuous testing practices
•
Communicate complex findings through concise technical reports, executive summaries, risk statements, and presentations tailored to technical and non-technical audiences
•
Understand and adhere to company risk, security, compliance, audit, and regulatory requirements
