## Description

Block is one company built from many blocks, all united by the same purpose: economic empowerment.

The Network Edge Security team builds tools that provide important insights into our API Security posture and trustworthiness of traffic flowing into our systems.

The Role: The Network Edge Security team builds the tools that provide important insights to our API Security posture and trustworthiness of traffic flowing into our systems. Our capabilities use machine learning, streaming analytics, and significant data analysis to provide insights into understanding our network edge risk exposure and the true sources of our request flows. The team’s primary focus is up-leveling our API security posture for downstream products and services. However, there is also a need at times to respond quickly to emerging threats to take action at the edge to provide immediate relief.

Responsibilities:

- Respond and mitigate emerging threats and attacks at our network edge by leveraging WAF rules, bot vendors, and other CDN-native technologies

- Help build out infrastructure that gives us better inventory of our network edge security posture

- Build out and maintain a near-real time streaming analytics data pipeline and application

- Contribute to the evolution of our labeling and ML model development

- Help manage and maintain our systems across build, deploy, and production monitoring

- Be flexible with respect to computer languages as we use Java, Kotlin, Python, TypeScript, PySpark and others as needed or appropriate

- Evaluate and build integrations with vendor systems that may be used in addition to in-house solutions

- Develop and implement AI-driven capabilities to automatically classify and mitigate abusive traffic patterns

Requirements:

- 5+ years of software or security engineering experience developing scalable production software incorporating testing, evaluation, and monitoring

- Bachelor's degree in Computer Science or equivalent practical experience

- Proficient in Java, Kotlin, Typescript, and Python

- Proficient in data analysis using SQL and Spark

- Experience implementing and maintaining applications in both a CDN (Cloudflare and Fastly) and Amazon Web Services (AWS) ecosystems

- Familiarity with Snowflake, Databricks, and Datadog are a strong plus

Benefits: Every benefit we offer is designed with one goal: empowering you to do the best work of your career while building the life you want. Remote work, medical insurance, flexible time off, retirement savings plans, and modern family planning are just some of our offering.
