Senior Security Engineer, Detection Engineer

We need to output HTML fragment with sections: About the role? The posting includes description: "CoreWeave is The Essential Cloud for AI™..." That's about company. Could be "About the role" or "About the company". The instruction: use

for section headings (e.g. About the role, Responsibilities, Requirements, Qualifications, Skills, Benefits, Pay, Schedule). Use

• for any list of duties/requirements/benefits, and

  for prose. Do NOT repeat the job title as a heading (the page already shows it) and do NOT put Job ID / requisition numbers as headings — fold minor metadata into a short

  or drop it. Preserve ALL substantive information; do NOT invent or summarize away detail. Remove cookie/navigation/legal/EEO/equal-opportunity/scam-warning boilerplate, duplicated lines, and application instructions. IMPORTANT: include a section ONLY when the posting has real, specific content for it — never emit a heading followed by filler/placeholder text (e.g. "commensurate with experience", "not specified", "N/A", "varies", "TBD") and never create Pay/Schedule/Benefits sections unless the posting actually states them. Prefer a few substantive sections over many thin ones. Output ONLY the HTML fragment — no /, no markdown code fences. We need to extract sections: About the role (maybe description of what you'll do). Responsibilities (list of duties). Requirements (minimum qualifications). Qualifications (maybe preferred qualifications). Skills (maybe not separate). Benefits (list). Pay (salary range). Schedule (maybe mention on-call hours). The instruction: include a section ONLY when posting has real, specific content for it. So we need to see if each section has content. Let's parse posting: - Intro: "CoreWeave is The Essential Cloud for AI™..." This is company description. Could be "About the role"? Actually "About the role" would be description of role. The posting includes "What You’ll Do On this team, you will:" then bullet list (Design cutting-edge detection strategies..., Collaborate..., Enjoy...). That's responsibilities? Actually it's more like role overview. Then "In This Role, You Will Be Responsible For" then list of responsibilities. Thus we could have sections: About the role (maybe the "What You’ll Do" paragraph). Responsibilities (the list after "In This Role, You Will Be Responsible For"). Requirements (Minimum Qualifications). Qualifications (Preferred Qualifications). Benefits (list under "What We Offer"). Pay (salary range). Schedule (on-call hours mention). Also maybe Skills? Not separate. We must not repeat job title as heading. No Job ID. We must remove boilerplate: EEO, Export Control Compliance, California Applicants, etc. Also remove "Learn more at www.coreweave.com." maybe keep? It's not substantive? It's company link; maybe keep as part of About the role? Might be considered boilerplate? It's not navigation/legal/EEO. It's a link to learn more; could be considered minor metadata. Probably we can drop it. Also remove duplicated lines. We need to preserve ALL substantive information; do not invent or summarize away detail. Thus we need to include all bullet points exactly as given, maybe rephrase? Must preserve detail, not summarize. So we need to copy the bullet points verbatim (or close) inside

• . Ensure we don't lose any. Let's extract: Company description: "CoreWeave is The Essential Cloud for AI™. Built for pioneers by pioneers, CoreWeave delivers a platform of technology, tools...". We'll keep as prose under About the role. What You’ll Do On this team, you will: - Design cutting-edge detection strategies at scales most security engineers only dream about - Collaborate with talented peers in an innovative environment focused on excellence - Enjoy the autonomy and encouragement to innovate and influence CoreWeave’s security landscape directly In This Role, You Will Be Responsible For: - Developing and implementing advanced threat detection capabilities to proactively identify and mitigate cyber threats - Crafting precise and efficient custom detection logic tailored to evolving threat landscapes - Leading and/or participating in real-time security incident response, threat containment, and remediation. - Conducting proactive threat-hunting exercises to uncover hidden vulnerabilities and anticipate threats - Collaborating closely with cross-functional teams to enhance security visibility and detection effectiveness - Continuously researching and staying informed about emerging threats, attack vectors, and detection methodologies - Participating in strategic security initiatives, contributing your expertise to security architecture and controls - Engaging in security assessments to uphold our high standards for security and compliance - Occasionally, drawing the owl - figuring out innovative solutions while navigating ambiguous situations Investing in our people is one of our top priorities, and we value candidates who can bring their diversified experiences to our teams.
