Who You Are (Success Profile)
You thrive in ambiguity. You're comfortable building the path as you walk it. You thrive in a dynamic environment, seeing ambiguity not as a hindrance, but as the raw material to build something meaningful.
You act like an owner. Your passion for the mission fuels your bias for action. You operate with integrity because you genuinely care about the outcome. True ownership involves leveraging dynamic range: the ability to navigate seamlessly between high-level strategy and hands-on execution.
You are a problem-solver. You love running towards the challenges because you are laser-focused on finding the solution, knowing that solving the hard problems delivers the biggest impact.
You are a high-trust collaborator. You are ambitious for the team, not just yourself. You embrace our challenge culture by giving and receiving ongoing feedback—knowing that candor delivered with clarity and respect is the truest form of teamwork and the fastest way to earn trust.
You are a learner. You have a true growth mindset and are obsessed with your own development, actively seeking feedback to become a better partner and a stronger teammate. You love what you do and you do it with purpose.
What We’re Looking for (Minimum Qualifications)
Foundational understanding of AI/ML technologies and experience leveraging, securing, or positioning AI-driven solutions to optimize outcomes within your functional domain
Proven experience in detection engineering, threat hunting, security operations, or malware analysis
Hands-on experience developing and implementing detection rules in SIEM tools such as Splunk, Microsoft Sentinel, or ElasticSearch
Deep familiarity with the MITRE ATT&CK framework and experience translating TTPs into actionable detection logic
Bachelor’s or graduate degree in Computer Science, Engineering, or a related discipline, or equivalent security industry experience, combined with the ability to work flexible schedules, including weekend night shifts, to meet global operational demands
What Will Make You Stand Out (Preferred Qualifications)
Experience leveraging AI/ML models, large language models (LLMs), or natural language processing (NLP) to automate threat intelligence synthesis, accelerate detection rule generation, or build predictive anomaly detection models within big data systems
Significant experience as a Senior Detection Engineer leading complex detection strategies and mentoring junior team members
Expertise in validating detection logic, performing root cause analysis of failures, and delivering platform improvement recommendations, paired with advanced scripting and automation skills in Python for developing and managing complex detection infrastructure
