We cultivate a culture that gives every CrowdStriker both the flexibility and autonomy to own their careers. We're always looking to add talented CrowdStrikers to the team who have limitless passion, a relentless focus on innovation and a fanatical commitment to our customers, our community and each other. Ready to join a mission that matters? The future of cybersecurity starts with you.

About the Role:

The Falcon Cloud Security (FCS) Detection Engineering team enables CrowdStrike's primary mission of Stopping the Breach, through a shift-left approach that focuses on helping customers of cloud computing manage their risk posture. We do this by writing and maintaining detection rules that assess cloud assets to identify risks and opportunities for improvement. We start by using research to define best practices for cloud security, which we translate into detection rules we author and deploy as code into the FCS product ecosystem. In addition to posture management, the Detection Engineering team researches threats to cloud services & assets, and writes detection rules to identify abuses and attacks.

This role combines a blend of skill sets including security operations & incident response, data analytics, risk management, software development, and threat research. If you enjoy researching cloud security issues and developing detection content as code, all in a fast-paced environment with broad collaboration across a diverse team, this role is for you.

What You'll Do:

As a member of the Falcon Cloud Security Detection Engineering team, you will be responsible for performing research into cloud threats, vulnerabilities, and abuses, to determine configuration best practices that can be used to secure cloud services and assets.

You will also be responsible for developing and deploying detection rules as code into the FCS product ecosystem along with writing descriptions that customers will use to understand and action alerts generated by these rules.

The focus of this role is on cloud security posture, and the relevant features are misconfiguration alerts, cloud risks, attack paths, identity and exposure analysis, and much more.

This role will honor a working day within local standard business hours for each team member, but will also require regular participation in team meetings and live collaboration with US-based staff.

• Translating use case descriptions into requirements for new code
• Configuring cloud assets to match the use case
• Writing code that searches collected data for attributes matching our use case
• Bundle the code into a productized template with additional descriptive data
• Deploy and test the new code in the product pipeline
• Deploy and validate the new code in production
• Perform ongoing maintenance / support for our new code
• This is mostly software development, although closer to what we call content development in the security world, but done in a SaaS ecosystem.
• This is also all done within the context of cloud security, but specifically of cloud governance, risk management, and compliance (GRC).

What You'll Need:

• Professional experience in cloud security-related operations and engineering roles, specifically related to threat detection, incident response, and risk management.
• Experience with data analytics, including searching large data sets, correlating attributes, interpreting results, extracting insights, and forming data-driven conclusions.
• Experience with searching data with analytics tools including Elastic Search, Splunk, or a SIEM.
• A working practical knowledge of at least one of the following Cloud Service Providers: AWS, Azure, GCP, OCI.
• A practical understanding of industry security standards and control frameworks such as NIST, CISA, CIS, HIPAA, HISTRUST, PCI and others.
• Experience developing, deploying, and maintaining code in formalized software development/CICD workflows including the use of BitBucket to manage code deployments.
• Familiarity with the Agile methodology for project management.
• Experience in a DevOps or similar role that required use of Python and GO.
• Ability to author and run Elastic Search queries and interpret results from large data sets.
• Proficient in the English language with strong written and verbal communication skills.
• A passion for quality and experience optimizing results.

Bonus Points:

• Experience writing detection rules with the Open Policy Agent query language, Rego.
• Having served in a role focused on Detection Engineering; writing detection rules used by other teams.
• Formalized training or certification in cloud computing, including administration, development, engineering, or architecture.

The work:

We develop and insert new code into a SaaS platform by updating configuration files read by custom-built services in a data analytic and presentation ecosystem. The code we deploy into the SaaS platform is designed to read cloud asset configurations, compare them to configuration standards, and generate a "finding" if the asset configuration "fails" one of our checks.

We receive content use cases in the form of loosely described requirements, or a configuration scenario or best practice. We then create cloud assets and configure them to match the described scenario. Then we capture the data that is generated in our SaaS pipeline from our cloud assets and we use it to author a content rule that checks other cloud assets for that same configuration state. We deploy these into the product ecosystem through CI/CD processes as templates with additional meta data that describes the scenario to customers of the platform.

Benefits of Working at CrowdStrike:

• Remote-friendly and flexible work culture
• Market leader in compensation and equity awards
• Comprehensive physical and mental wellness programs
• Competitive vacation and holidays for recharge
• Paid parental and adoption leaves
• Professional development opportunities for all employees regardless of level or role
