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

Education and Experience Required:

Combined minimum of 8 years’ higher education and/or work experience in systems design, management and/or architecture

Strong understanding of the system development and infrastructure lifecycle and architecture, vendor best practices, IT Service Management, and systems design

Minimum of 8 years of professional experience in software testing, performance engineering, software engineering, or a related technical engineering discipline

Minimum of 5 years of hands-on experience developing and executing enterprise performance tests with OpenText Core Performance Engineering (LoadRunner Cloud), LoadRunner Enterprise, or LoadRunner Professional/VuGen

Advanced experience designing performance test strategies, workload models, success criteria, and test scenarios for complex or distributed systems

Advanced experience developing and maintaining performance test scripts, including C-based VuGen scripting and JMeter

Demonstrated experience analyzing application performance and leading investigation of complex bottlenecks using APM and observability data

Experience providing technical leadership across multiple teams or initiatives and mentoring less-experienced engineers

Experience working within Agile, DevOps, CI/CD, risk-management, and production-readiness processes

Education and Experience Preferred:

Experience with BlazeMeter, Azure Load Testing, or other cloud-based performance testing platforms

Experience with Dynatrace, AppDynamics, New Relic, or comparable Application Performance Monitoring and observability platforms

Experience testing enterprise-scale digital, mobile, API, event-driven, cloud, containerized, and distributed systems

Experience with Kubernetes, OpenShift, Azure, AWS, databases, middleware, messaging, and network-related performance analysis

Financial services or other highly regulated industry experience

Experience developing performance engineering standards, governance, reusable frameworks, or enterprise testing practices

Performance testing, cloud, DevOps, software engineering, or industry-recognized technical certifications.
