About Us: We are a Series-A cybersecurity startup, helping SOC teams manage their distributed security data by leveraging cutting-edge AI and streaming technologies. Our Security Data Fabric normalizes, enriches, and correlates security data from dozens of disparate sources in real-time. This creates the high-fidelity data foundation needed to power next-generation AI-SIEMs, while reducing customer data costs through intelligent filtering. We are seeking a Senior Security Engineer to collaborate directly as a security subject-matter-expert (SME) on AI/ML product features

Role Overview: As a core security expert on our AI team, you will be a bridge between real-world cyberattacks and our AI-driven Data Fabric. You will fundamentally shape how our product helps SOC teams make use of their security data to stop attacks. You will work directly with ML Engineers and Data Scientists on product features that leverage GenAI and ML techniques. You will own the security efficacy of recommendations and detections-in-the-pipeline that we provide to our customers. Your work will extend the capabilities of our cutting-edge Data Fabric technology, and make managing complex security pipelines simple, so that SOC teams can focus on catching attackers and keeping their businesses safe.

Key Responsibilities:

• Security expertise: Serve as an embedded security SME within our AI/ML feature team, guiding development and ensuring our product addresses the most critical attacker behaviors
• Innovation: Translate emerging TTPs (Tactics, Techniques, and Procedures) into innovative solutions for enriching data in the Fabric.
• Validation: Design and build test harnesses to measure the security efficacy and false-positive rates of our AI-driven recommendations and detections.
• Curate security data: Partner with Data Scientists to curate and label high-quality security datasets (e.g. malicious vs. benign log event sequences) to train our models.
• Thought leadership: Publish research, blog posts, and technical content that showcases our unique capabilities, and establishes you and Realm as leaders in AI-driven security.
• Project Ownership: Take ownership of project deliveries and stay connected with Product requirements.
• Collaboration: Partner with Engineering and ML/AI experts to bring features to production.
• Learning Champion: Continually learn about new cyberattack vectors and techniques to proactively address them in our product.

Qualifications:
Experience:

• 4+ years in hands-on security role with a focus on detection engineering, threat hunting, security data analysis, or threat research.
• Bachelor’s degree in Cybersecurity, Computer Science, STEM, or related field; MS preferred.
• Professional security certification (e.g. CISSP, OSCP, GCIH) preferred.

Technical Skills:

• Deep expertise analyzing and querying large-scale security logs from sources like EDR, cloud audit logs, and network sensors.
• Proficiency with at least one data query language such as SQL, KQL, Splunk SPL, or similar.
• Expert-level understanding of the data schemas and event logs generated by security tools (EDR, SIEM, etc.).
• Experience with Open Cybersecurity Schema Framework (OCSF) is preferred.
• Proven expertise in cyberattack methods and techniques used by threat actors.
• Strong understanding of network protocols, cryptography, application security (OWASP Top 10), and operating system internals.
• Hands-on experience securing public cloud environments (AWS, Azure, or GCP).
• Proficiency in at least one scripting language (Python, Bash, PowerShell, etc.).
• Experience with Infrastructure as Code (IaC) tools is a plus.

Soft Skills:

• Excellent problem-solving skills and attention to detail, with a passion for learning new technologies and innovating.
• Effective communication and collaboration skills, with the ability to work well in a fast-paced, dynamic startup environment.

Benefits:

• Fully remote team.
• We foster a collaborative and inclusive culture, prioritizing sustainable team growth and a strong commitment to work-life balance.
• Opportunity to join an early-stage company and make a significant impact in shaping and improving our core infrastructure.
• Competitive salary and equity package.
• Comprehensive health, dental, and vision insurance plans.
