Software-Based Load Balancing Expert - remote - consultancy

This is a remote position. We are looking for an experienced engineer or architect who has personally designed and implemented large-scale, horizontally scalable software load balancing solutions , using technologies such as HAProxy, NGINX, or equivalent. The objective is to learn from practical experience how software-based load balancing can provide the required capabilities without relying on hardware load balancer appliances. Specific scope: • Architectures supporting hundreds of thousands of requests per second. • Horizontally scalable farms of software load balancers. • Load balancing a single application exposed through a single IP address. • Design approaches such as Anycast, hierarchical load balancing, or other relevant architectures. • Understanding the design, advantages, disadvantages, and trade-offs of these approaches. • Limited header rewriting requirements. The opportunity would initially involve short-term technical consulting, with potential for further work as the project progresses. Requirements • Strong experience with F5 BIG-IP • Hands-on experience with HAProxy, NGINX or similar software load balancers • Strong knowledge of HTTP, HTTPS, TCP and SSL termination • Experience designing high-throughput, highly available load-balancing platforms • Knowledge of Anycast, horizontal scaling and multi-tier load-balancing architectures • Experience with header/content rewriting is beneficial Key requirement: We are specifically looking for someone with hands-on experience building and operating solutions of this type at scale, rather than someone offering a theoretical assessment.
