Software Tester (QA & Performance)

At InnoWave, quality is built in at every layer and performance is one of them. We're looking for a Software Tester who moves comfortably between QA testing and performance assessments, owning both with the same rigor, from our internal projects to full performance engagements. If you're based in Lisbon, this might be the opportunity for you!

Software Tester (QA & Performance)

Responsibilities

• Own performance testing end-to-end: assess the solution independently and define the right approach - normal usage, peak/load and stress scenarios, and large-scale testing to establish maximum capacity.
• Select and own the appropriate tooling for each performance assessment (e.g. JMeter, LoadRunner, or other, as best fits the context).
• Measure and report on response time, processing speed, data transfer speed, network usage, maximum concurrent users, and memory utilization.
• Support internal QA testing projects alongside performance work, including test case design, execution, and defect reporting.
• Analyze results, identify bottlenecks and risks, and produce clear, actionable reports with recommendations.

Required Skills

• Proven, hands-on experience in performance testing, able to run assessments and execute independently.
• Strong knowledge of performance testing tools such as JMeter, LoadRunner, or equivalent.
• Solid understanding of load, stress, and capacity testing methodologies.
• General QA testing experience (manual and/or automated), comfortable moving between performance and functional testing work.
• Clear communication skills, able to translate technical results into actionable recommendations.
• Fluent in English - written and spoken (mandatory).
• Based in Lisbon, with availability to work in a Hybrid model.

Preferred Skills

• Integrating performance test suites into CI/CD pipelines.
• Experience with async and queue-based load testing.
• Routine use of AI tools to support test generation or analysis.
