Together with our partners, we’re helping customers break free from the restrictive, overpriced legacy solutions that hold them back, and blaze forward with the full power of the open cloud in their hands.\nFounded in 2007, we scaled the business with less than $3 million in outside funding until 2021, when we did a traditional IPO on the Nasdaq stock exchange. Today, Backblaze generates over $136M ARR and is the leading specialized storage cloud, managing over three billion gigabytes of data storage for 500K+ customers in 175+ countries, including businesses, developers, IT professionals, and individuals.\nBut while there is a lot to celebrate in our past, there is almost as much opportunity ahead of us. We’re seeking a Red Team Security Engineer to join our team!\nAbout the Role\nThe Red Team Security Engineer continuously validates whether vulnerabilities, configurations, identities, applications, infrastructure, and AI-enabled systems can be exploited by realistic adversaries. The role combines traditional offensive security with AI-assisted and agentic adversary emulation to validate exposure and continuously improve defensive controls.\nKey Responsibilities\nEmulate external attackers, malicious insiders, compromised identities, and autonomous adversarial agents.\nValidate whether vulnerabilities and configuration weaknesses identified are reachable and practically exploitable.\nDevelop and execute realistic attack paths across web applications, APIs, cloud infrastructure, identity systems, endpoints, and other enterprise services.\nUse AI-assisted and agentic techniques for reconnaissance, vulnerability analysis, attack-path discovery, and controlled offensive testing.\nTest AI applications and agents for prompt injection, tool abuse, excessive privilege, identity compromise, and other emerging attack classes.\nValidate compensating controls and mitigations before or after deployment.\nConduct purple-team exercises with Security Analytics and Security Operations to validate telemetry, detection, and response effectiveness.\nTranslate offensive findings into actionable improvements to architecture, configuration, detections, and response capabilities.\nQualifications\nExperience in red teaming, penetration testing, adversary emulation, or offensive security engineering.\nStrong web, API, cloud, identity, operating-system, and network security fundamentals.\nExperience validating practical exploitability and developing realistic attack paths.\nStrong understanding of MITRE ATT&CK and modern adversary techniques.\nFamiliarity with OWASP Top 10 for LLM, OWASP Top 10 for Agentic Applications, and MITRE ATLAS.\nScripting or software-development experience.\nExperience safely using automation or AI-assisted techniques in offensive-security workflows.\nExperience assessing cloud-native or AI-enabled systems, conducting purple-team exercises, or simulating autonomous adversaries is preferred.\nAt this point, we hope you're feeling excited about the job description you're reading. Even if you don't meet every requirement, we still encourage you to apply. Learning, developing, and growing are key parts of our culture.
