WHAT CAN YOU EXPECT?

Our client is committed to developing and operating modern, cloud-native applications with the primary goal of improving operational efficiency and delivering an outstanding user experience.

The Digital Factory team acts as a strategic partner to implement state-of-the-art IT solutions for clients and employees. To achieve this mission, the team collaborates closely with business units, IT departments, and third-party vendors.

You will work with cutting-edge development tools and best-in-class DevOps processes. Together with a young and highly motivated team, you will build and manage high-impact performance engineering solutions.

YOUR CHALLENGE

Are you excited to join an engineering team that systematically tests new and existing solutions? Do you have a natural curiosity to uncover bottlenecks and the technical skills to resolve them? Are you motivated to take ownership and help build high-performing frontend solutions in a corporate environment?

We are looking for a Performance Engineer focused on performance testing and optimization, who combines technical expertise with strong analytical skills and a passion for problem-solving. In this role, you will:

Performance Testing & Optimization

• Conduct performance, load, and stress tests on web applications to ensure compliance with defined SLAs.
• Analyze frontend performance using modern tools (e.g., Lighthouse, WebPageTest, Dynatrace) and browser developer tools.
• Identify performance bottlenecks across frontend, APIs, and infrastructure, and recommend improvements.

Collaboration & Quality Assurance

• Work closely with developers, testers, architects, and business stakeholders to integrate performance testing into CI/CD pipelines.
• Document test strategies, scenarios, and results with clear reporting for both technical and non-technical audiences.
• Contribute to building a performance-first culture by coaching teams and embedding testing early in the development lifecycle.

Monitoring & Incident Management

• Monitor production environments using real-user monitoring (RUM) and synthetic testing solutions.
• Proactively identify risks and potential degradations in application performance.
• Support troubleshooting of performance-related incidents across multiple system layers.

YOUR PROFILE

Education & Experience

• Bachelor's degree in Computer Science, Information Technology, or a related field.
• 2–4 years of experience in performance testing, ideally in banking or financial services.

Performance Engineering Expertise

• Strong knowledge of performance testing tools (e.g., JMeter, Gatling, LoadRunner, k6).
• Experience with frontend monitoring frameworks and developer tools.
• Proficiency in scripting and test automation (JavaScript, Python, or similar).
• Familiarity with CI/CD environments (Jenkins, GitLab CI, Azure DevOps).
• Solid understanding of frontend-oriented development, including:
• Web technologies (HTML, CSS, JavaScript, React/Angular)
• Performance optimization techniques (lazy loading, caching, CDN, minification)
• Backend/API dependencies and their impact on frontend performance
• Cloud and containerized environments (Docker, Kubernetes)

Nice-to-Have

• Experience in the banking sector or secure, regulated environments.
• Exposure to synthetic monitoring and observability solutions (New Relic, AppDynamics, Elastic APM).
• Knowledge of accessibility, security, and compliance standards in frontend applications.

Communication & Stakeholder Management

• Excellent communication and reporting skills, with the ability to interact confidently with both technical and business teams.
• Strong problem-solving mindset, capable of working independently and collaboratively in an international setup.
