What is a performance tester?

Performance Testers are IT professionals who evaluate the speed, responsiveness, and stability of computer systems, software applications, or networks under a particular workload. Their main role is to ensure that products meet defined performance criteria before they are released, identifying bottlenecks and recommending improvements. Performance Testers use specialized testing tools to simulate various user loads and analyze how a system behaves under stress. This helps organizations deliver reliable and efficient software that performs well under expected and peak usage conditions.

What are the key skills and qualifications needed to thrive as a performance tester?

To thrive as a Performance Tester, you need a solid grasp of software testing principles, scripting, and analysis, typically supported by a background in computer science or related fields. Familiarity with performance testing tools like JMeter, LoadRunner, and monitoring systems, as well as relevant certifications such as ISTQB, is highly valuable. Strong analytical thinking, attention to detail, and effective communication ensure thorough test execution and clear reporting of performance issues. These skills are crucial for identifying and resolving system bottlenecks, ensuring reliable software performance under varying loads.

What are some common challenges faced by performance testers during large-scale application testing?

Performance Testers often encounter challenges such as accurately simulating real-world user loads, identifying bottlenecks in complex environments, and managing test environments that closely mirror production. Coordinating with development, DevOps, and business teams is essential to ensure that test scenarios reflect actual usage patterns. Additionally, interpreting test results to provide actionable insights requires a strong understanding of both the application architecture and underlying infrastructure.

What is the difference between Performance Tester vs QA Tester?

Performance Testers specialize in evaluating system performance under load, while QA Testers focus on overall software quality and bug detection. Both roles are essential in ensuring software reliability, but Performance Testers concentrate on speed, scalability, and stability, whereas QA Testers ensure the product meets quality standards across all aspects.

How much do performance testers make in the US?

Performance testers in the US typically earn between $70,000 and $120,000 annually, depending on experience, location, and certifications. Entry-level roles may start around $60,000, while senior positions with specialized skills can exceed $130,000.

Job description

Description

SHINE Technologies is seeking a Commissioning Engineer who will be responsible for planning and scheduling facility testing, commissioning, and validation activities for all facility equipment and components, including first-of-a-kind and highly specialized nuclear and chemical processing equipment, at the new NRC-licensed isotope production facility in Janesville, Wisconsin. The Commissioning Engineer will report to the Commissioning Manager and will ensure that testing and commissioning activities are safely and efficiently completed prior to the transition to regular facility operations.

The base salary range for this position is $125,000 - $145,000 per year plus a comprehensive compensation package. Our salary ranges are determined by role, level, and location.

Duties and Responsibilities:

Specific duties and responsibilities include, but are not limited to:

  • Promote a safe work environment and strong safety culture.
  • Report to the Commissioning Manager and execute assigned activities in accordance with the Chrysalis Project Commissioning Plan, approved procedures, project requirements, applicable codes, and SHINE quality requirements.
  • Develop a working knowledge of assigned systems, including their design basis, intended operation, control philosophy, interfaces, and acceptance criteria.
  • Review drawings, specifications, submittals, vendor documentation, P&IDs, control narratives, and sequences of operation to identify commissioning requirements, design conflicts, incomplete requirements, and testing concerns.
  • Participate in design, constructability, commissioning, and system-readiness reviews.
  • Assist in developing and maintaining system boundaries, subsystem breakdowns, the systemization register, and turnover packages.
  • Prepare commissioning checklists, inspection forms, test procedures, data sheets, and acceptance criteria.
  • Perform and document installation inspections to verify that equipment and systems comply with approved drawings, specifications, codes, and manufacturer requirements.
  • Verify that required prerequisites are complete before equipment energization, startup, or testing.
  • Coordinate commissioning activities with Construction, Engineering, Quality Assurance, Operations, Maintenance, EHS, vendors, contractors, and system integrators.
  • Support or conduct factory acceptance tests, site acceptance tests, vendor demonstrations, equipment startup, functional performance testing, control-loop verification, and sequence testing.
  • Support integrated system testing and verify interfaces among mechanical, electrical, instrumentation, controls, process, utility, and life-safety systems.
  • Identify, document, track, retest, and verify closure of deficiencies, nonconforming conditions, failed tests, and punch-list items.
  • Maintain complete, accurate, legible, and auditable commissioning records in the designated commissioning management system.
  • Support commissioning schedules and look-ahead plans, and regularly report progress, system readiness, testing status, constraints, issues, and resource needs to the Commissioning Manager.
  • Participate in turnover walkdowns and coordinate with Construction and Operations to support the transition from construction through component testing, facility commissioning, and operational turnover.
  • Review operating and maintenance procedures, spare-parts requirements, training materials, and operations-and-maintenance manuals.
  • Assist with Operations and Maintenance training and document completion of required training activities.
  • Support preparation of commissioning reports, test summaries, deficiency logs, turnover records, and final system acceptance documentation.
  • Participate in lessons-learned reviews and recommend improvements to commissioning procedures, testing methods, and project execution.
  • Perform other commissioning-related assignments as directed by the Commissioning Manager and within established authority and qualification limits.

Requirements

  • Bachelorโ€™s degree in relevant engineering or related technical field or appropriate industry experience
  • A minimum of five (5) yearsโ€™ experience in construction, startup, testing, commissioning, operations, or facility engineering. Some supervisory experience is a plus.
  • Experience in Navy Nuclear or nuclear facility engineering, operations, maintenance, or equivalent in an NRC or DOE regulated environment desired.
  • Excellent attention to detail and task management skills.
  • Nuclear or pharmaceutical industry experience preferred.
  • Previous experience in using scheduling software (e.g., Primavera P6, Microsoft Project) preferred.
  • Ability to work safety within an industrial and radiation environment.
  • The position may require non-standard work hours and shift work, including nights and weekends, on a periodic, rotational, or ongoing basis.
  • This role ends at the completion of facility commissioning, which is expected to conclude in 2030. The individual will have the opportunity to apply for other available roles within SHINE at that time.

Eligibility for employment is conditioned on the applicants ability to qualify for access to information subject to U.S. Export Controls. Additionally, applicants eligibility may be conditioned based upon meeting the Nuclear Regulatory Commission requirements for access to Safeguards Information, which typically requires a pre-employment drug screen, fingerprinting and criminal background check.
