Software Dev Engineer AWS WAF Bot Control and Fraud Prevention

We make it easy for customers to author and associate firewall policies to help protect their web applications from attacks by allowing them to configure rules that allow block monitor (count) or CAPTCHA web requests based on conditions that they define. These conditions include IP addresses HTTP headers HTTP body URI strings SQL injection and crosssite scripting. By supporting association with CloudFront Application Load Balancer API Gateway and AppSync customers can protect their applications and resources whether all in on the Cloud maintaining on premise data centers or using a hybrid Cloud approach.

We build a highly available low latency distributed system that allows customers to propagate changes worldwide in minutes to respond to active attacks in realtime. Were fully integrated with several others AWS Services to give customers the insight and control they need. With CloudWatch and Sampled Web Requests we give customers the visibility they need see which requests were blocked allowed or counted and what rule was matched on a given request (i.e. this web request was blocked due to an IP address condition etc.. Using AWS Firehose customers can store their full WAF logs for compliance and auditing as well as use them for debugging and additional forensics. We support using AWS Config to track historical changes to the rules and metrics associated with their WAF RuleGroups. Using CloudFormation customers can automate the deployment of their WAF Security Automations on the AWS Cloud.

We own the direct customer experience as well as the per request processing of rules for CloudFront API Gateway and ALB. Not only do we build an AWS Security service but were a customer of AWS using other AWS services to provide the solutions to our customers that scale and seamlessly integrate with their existing workflows. Engineers on our team get to solve some of the hardest computer science problems including building highly available distributed microservices global scaling across both AWS Regions and CloudFront edge locations and processing millions of requests with single digit millisecond latency.
