If that is you, please apply!\nAbout the Role\nFluidstack operates the compute infrastructure powering frontier AI. The work running on it is among the most consequential being done today, and the adversaries interested in it are among the most sophisticated, persistent, and well-resourced anywhere. We are building Detection & Response Engineering from the ground up: engineering-led, agent-first, and built to scale across IT, OT, and physical surfaces. As the Staff Detection Engineer for IT, you lead detection engineering for Fluidstack’s IT surface. You set the standards that every detection engineer who follows inherits, and lay the foundations of detection on some of the most critical infrastructure being built today.\nWhat you’ll do\nLead detection engineering for Fluidstack’s IT surface, including cross-domain detections where IT bridges OT or physical surfaces.\nAuthor and tune production detections as code, with peer review, CI/CD, and measured precision and recall.\nApply AI and machine learning to build effective detections, including behavioral analytics and anomaly detection at scale.\nDevelop novel detection tooling, including agentic capabilities that use LLMs for triage, investigation, and response.\nSet the engineering standards, coverage methodology, and quality metrics for the detection engineering discipline.\nConduct threat and security research that informs detection logic, surfaces coverage gaps, and drives new detections.\nPartner with security platform engineers, incident response, and threat intelligence to close the detection-to-response loop.\nParticipate in the on-call rotation for incident response.\nAbout You\nYou have strong detection engineering experience and have built detection programs at scale.\nYou are fluent across coding and querying languages, pick up new ones quickly, and have handled security-relevant data at massive scale and complexity.\nYou have written sophisticated detection logic against diverse telemetry, not synthesized it from vendor templates.\nYou have handled security incidents and investigated anomalies as part of a team.\nYou have set up detection CI/CD, or know how you would build it on day one.\nYou have well-founded opinions on what makes a detection program work in production.\nYou read the agent-first thesis as the most interesting design choice in security operations right now.\nYou have built or contributed to internal tooling, not just consumed commercial products.\nYou see what is needed, scope it yourself, and run with it.\nStrong candidates may also have\nExperience building or operating agentic detection tooling using LLMs.\nExperience designing and tuning LLM-based triage or investigation systems against measured precision and recall.\nExperience with Python and SQL applied to detection development and security data analysis.\nExperience at the boundary between detection engineering and security platform engineering at scale.\nBackground in detection or security engineering at GPU compute, HPC, or other hyperscale infrastructure.\nSalary & Benefits\nCompetitive total compensation package (salary + equity)\nRetirement or pension plan, in line with local norms\nHealth, dental, and vision insurance\nGenerous PTO policy, in line with local norms\nThe base salary range for this position is $250,000 - $330,000 per year, depending on experience, skills, qualifications, and location.
