Performance Tester – Aviation & Mission-Critical Systems
For one of our clients, RSB Automotive Consulting is looking for a Performance Tester to join a team working on advanced, data-driven platforms in the aviation and mission-critical domain. The environment is focused on high-complexity systems supporting large-scale, global operations where performance, stability, and reliability are absolutely critical. The solutions are used in domains similar to aviation and transportation ecosystems, where system behavior under peak load directly impacts real-world operational outcomes. The team operates in an agile, engineering-focused setup, working across multiple countries in a distributed delivery model. The role is ideal for someone who enjoys deep technical analysis, performance engineering, and ensuring systems are fully ready for production-scale usage. The position is fully remote within the EMEA region, with flexible cooperation under B2B or UoP. Role Overview As a Senior Performance Tester, you will be responsible for designing and executing comprehensive performance engineering strategies for complex distributed systems. Your focus will be on ensuring scalability, stability, and readiness under real-world and peak-load conditions. You will act as a key quality gate for system performance, supporting engineering decisions with data-driven insights and technical analysis.
Key Responsibilities
Design and execute performance, load, stress, spike, and endurance testing strategies using LoadRunner Analyze system behavior under load and identify performance bottlenecks across application and infrastructure layers Develop and maintain performance test scripts and scenarios Use Python for automation, test data preparation, result analysis, and tooling development Collaborate closely with developers, architects, and DevOps engineers to resolve performance issues Define performance benchmarks, SLAs, and acceptance criteria for system readiness Analyze and interpret test results, delivering clear and actionable performance reports Support capacity planning and scalability assessments for production systems Integrate performance testing into CI/CD pipelines where applicable Participate in architecture and design reviews from a performance engineering perspective Continuously improve performance testing methodologies, tools, and practices
Requirements
Experience in aviation, transportation, or mission-critical systems 5+ years of experience in performance testing / non-functional testing roles Strong hands-on experience with LoadRunner Solid understanding of performance testing methodologies (load, stress, spike, endurance) Experience analyzing system, application, and infrastructure performance Practical experience with Python for scripting, automation, or data analysis Understanding of web-based, API-driven, and distributed systems Experience working in Agile/Scrum environments Strong analytical and problem-solving skills Ability to communicate technical findings clearly to technical and non-technical stakeholders Very good English communication skills in international teams
Nice to Have
Exposure to large-scale distributed systems and capacity planning Experience integrating performance testing into CI/CD pipelines Background in data-intensive environments
