- Collect necessary performance targets and/or KPIs from stakeholders’ pre-performance execution.
- Design, script and execute load, stress, and scalability testing and deliver comprehensive reports to the project team.
- Collaborate on performance related test cases to execute and provide necessary data to peers for bug entry.
- Report issues discovered during performance evaluation and work closely with the engineering team to analyze the issues and track them to resolution.
- Keep abreast of current performance testing methodologies, and work autonomously to update tools, skills, and techniques.
- Mentor Mid and Junior Engineers on Performance Testing best practices.

Performance Engineer Jobs in Pennsylvania: Frequently Asked Questions
How do you become a performance engineer in Pennsylvania?
Most paths start with a bachelor's degree in an engineering discipline, followed by gaining practical experience in testing, systems analysis, or reliability work. In Pennsylvania, engineers who offer services to the public or sign off on technical documentation typically pursue Professional Engineer licensure through the Pennsylvania State Registration Board for Professional Engineers, which requires passing the Fundamentals of Engineering and Principles and Practice exams. Relevant certifications in reliability or quality engineering also strengthen candidacy with Pennsylvania employers.
Which companies hire performance engineers in Pennsylvania?
Employers hiring performance engineers in Pennsylvania right now include Westinghouse Electric Company, UST, and Duolingo, based on current listings on Migrate Mate as of October 2026. Pennsylvania's concentration of defense contractors, utility providers, and advanced manufacturers means demand is distributed across both the Philadelphia region and the greater Pittsburgh area.
Which Pennsylvania cities have the most performance engineer jobs?
Cranberry Township, Pennsylvania, and Lititz account for the most performance engineer openings in Pennsylvania. Philadelphia leads because of its dense base of defense, infrastructure, and energy companies, while Pittsburgh draws heavily from manufacturing, robotics, and Carnegie Mellon University's affiliated technology sector, and smaller concentrations in areas like Allentown reflect the Lehigh Valley's industrial and utilities employers.
Are there remote performance engineer jobs in Pennsylvania?
Yes, but they're less common than in purely desk-based fields, since performance engineering often involves on-site testing, equipment access, or physical system validation. About 100% of performance engineer openings tied to Pennsylvania are remote or hybrid as of October 2026, with remote arrangements most frequently available for roles focused on data analysis, reporting, and software-based performance modeling rather than hands-on lab or field work.
How can I get hired as a performance engineer in Pennsylvania with little or no experience?
The most realistic entry point is an internship or co-op in an engineering testing or quality function, which large Pennsylvania employers in aerospace, utilities, and manufacturing regularly offer to students from schools like Penn State, Drexel, and Pitt. Candidates can also move laterally from quality assurance technician, test engineer, or reliability analyst roles. Passing the Fundamentals of Engineering exam early signals commitment to licensure and gives a clear edge with employers who require or prefer licensed engineers.
Where can I find and apply to performance engineer jobs in Pennsylvania?
You can find and apply to performance engineer jobs in Pennsylvania on Migrate Mate, which lists current openings from employers hiring across the state. Find roles that fit your experience and location and apply directly through each listing.
