Architecture - Performance Engineering Architect

Our Architecture Area is now hiring for a Performance Engineering Architect. Reporting into our Head of Architecture - you will interact with other Area Architects.

As a Performance Engineering Architect, you will be responsible for the overall architecture and design of performance-related aspects of software systems, with a strong focus on optimising both backend and frontend performance. You will collaborate with engineering teams to enhance system performance and scalability, identify performance bottlenecks, and implement strategies to improve overall system efficiency, including web page load times and user experience. Your role will ensure that both backend services and frontend applications meet rigorous performance standards while maintaining robustness and security. 

• Develop performance-focused architecture for both frontend and backend systems, ensuring scalability, low latency, and efficient resource utilisation across the stack. 
• Work with frontend developers to identify and eliminate bottlenecks, improving page speed, rendering performance, and overall user experience through techniques like lazy loading, image optimisation, reducing JavaScript and CSS payloads, and browser caching. 
• Conduct in-depth analysis of backend services and frontend web applications to identify performance bottlenecks, slow-loading pages, and suboptimal rendering. 
• Design and implement strategies for performance tuning across the entire stack, API response times, frontend rendering speed, and resource utilisation. 
• Design and guide performance testing strategies (load, stress, endurance) for both frontend and backend systems and ensure continuous performance monitoring post-deployment. 
• Identify and implement performance monitoring and profiling tools (e.g., Lighthouse, PageSpeed Insights) to automate performance testing and tracking. 
• Provide guidance and mentoring to frontend and backend engineering teams on performance best practices, from optimising API performance to ensuring fast page load times and smooth user interactions. 
• Create and maintain architectural documentation, frontend and backend performance benchmarks, and guidelines to support continuous improvement. 

• Minimum 5+ years of experience in performance engineering, software architecture, or related roles, with a strong understanding of performance optimisation for large-scale systems, including frontend and backend.  
• Solid understanding of networking concepts, microservices architecture, distributed systems, and cloud infrastructure (AWS, Azure, or GCP). 
• Experience optimising Single Page Applications (SPAs) and Progressive Web Apps (PWAs). 
• Experience with web performance metrics (e.g., Time to First Byte (TTFB), First Contentful Paint (FCP), Largest Contentful Paint (LCP), and Cumulative Layout Shift (CLS)). 
• Familiarity with CI/CD tools and practices (e.g., Jenkins, Github Actions, Teamcity). 
• Good analytical skills and ability to operate in a fast-paced environment. 
• Strong verbal and written communication skills to articulate performance considerations to technical and non-technical stakeholders. 
• Ability to lead by influence, collaborate across teams, and inspire best practices around full-stack performance engineering. 

Much like riding a rollercoaster, sometimes life at Betsson can be lightning fast with twists and turns but always FUN! Then again, what else would you expect from a business 75% millennial and 1700 strong, spread across 7 offices with 900 based out of our Malta HQ alone! We recognise it may not be for the faint-hearted, but if you’re a go-getter, initiator and adrenaline junkie, always striving to push the boundaries and challenge yourself, then you’ll fit right in.
