About This Job Family
People in this job family ensure products work as intended before customers find out they don't. They design test strategies, build automation frameworks, and catch bugs that would otherwise ship. Quality isn't just testing—it's building confidence that the product does what it should.
What You'll Do
Performance Engineers ensure systems handle load—designing load tests, analyzing bottlenecks, and preventing performance regressions. They think in terms of latency percentiles, throughput, and resource efficiency. Success means systems that stay fast under pressure.
- • Design and execute load tests independently
- • Analyze performance data to identify bottlenecks
- • Write comprehensive performance test suites
- • Design simple load scenarios for new features
- • Contribute to performance testing infrastructure
- • Report on performance trends and regressions
Every responsibility is an accomplishment waiting to happen. The question is: will you own the outcome, or just do the task?
AI as an Accelerator
AI isn't a skill we call out. It's invisible in the accomplishment but easily visible in the velocity and scale of your outcomes. Here's how people in this role are accelerating their work with AI:
- → Drafting test scenarios
- → Identifying bottlenecks
- → Generating reports

The Competencies That Matter
Skills fill your toolbox. Competencies are how you wield them. Three matter most at this level:
1. IT OPERATIONS (2) Strong IT Operations skills required at this level.
2. QUALITY ENGINEERING (2) Strong Quality Engineering skills required at this level.
3. ANALYTICS & BI (1) Strong Analytics & BI skills required at this level.
The radar shows the full picture. These three are where you need to be undeniable.
Your Journey From Here
Going up? Your next Tour of Duty:
→ Senior Performance Engineer - Performance (L3) "Lead a project that improves system performance"
The L2 → L3 gap is about OWNERSHIP: • From executing tasks → owning outcomes • From writing code → designing systems • From asking questions → answering them
These are your stretch accomplishments. Start doing L3 work now. When you can prove it with accomplishments, you're ready.
Going sideways? That's valid too.
Up isn't the only direction. It's your career. You own it.
