F5 builds the technology that sits in front of applications to keep them available, fast and protected. Its products handle load balancing and traffic management, application delivery across data centres and clouds, web application firewalls, protection against bots and automated fraud, denial of service mitigation, and the management of application programming interfaces. When a bank or an airline handles a surge of traffic without failing, F5 equipment or software is frequently part of the reason.
The company was founded in 1996 in Seattle, Washington, where it remains headquartered, and is listed on the Nasdaq. It employs roughly 6,000 people worldwide, with engineering and support operations across North America, Europe, Israel and Asia Pacific, including a substantial centre in Hyderabad, India.
F5 was originally known for its BIG IP hardware appliances, which became a standard fixture in enterprise data centres. As workloads moved to public cloud and containerised environments, the company extended into software and managed services, and expanded significantly through acquisitions: NGINX brought the widely deployed open source web server and reverse proxy along with its commercial editions, and Shape Security brought machine learning based detection of automated attacks and credential stuffing.
The result is a portfolio that spans three quite different delivery models. Hardware appliances remain in use where performance and control matter most. Software versions of the same capabilities run in private and public clouds. Distributed cloud services are delivered as a managed offering across a global network, aimed at customers who want security and traffic management without operating it themselves.
The engineering problems are characteristic of infrastructure sitting in the critical path of traffic. They include high throughput packet and connection handling, transport layer security termination at scale, low latency policy evaluation, distributed configuration management across many enforcement points, and the machine learning systems that separate legitimate users from automated abuse without adding friction for real customers.
Roles at F5 cover systems and network software engineering, security research and threat analysis, cloud and site reliability engineering, machine learning, hardware and platform engineering, technical support and solution architecture, and product management.
