Staff Detection Engineer
About Fluidstack
We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we've ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.
We're singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI.
We hire people who care deeply about this problem space. If that is you, please apply!
How We Operate
Extreme ownership. Full autonomy. Own things end to end often taking on scope outside your core role without being asked to get things done.
Velocity. We drive everything forward as fast as possible.
First principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins.
Love of the game. The frontier of AI is the most interesting problem of our time. We put in long hours at high intensity to push the frontier forward.
The Security & Corp IT Team
The Security & Corp IT team protects the people, systems, and infrastructure behind the largest AI compute buildout in history.
Examples of key problems the team is working on:
Build detection and response coverage across cloud (AWS/GCP/Azure), endpoint, and identity telemetry for a company whose attack surface spans corporate IT and gigawatt-scale data center infrastructure.
Run incident response end to end, from first alert through containment, remediation, and postmortem, without a large SOC to fall back on.
Stand up detection-as-code pipelines so every detection is versioned, tested, and deployed like software rather than hand-edited in a console.
Harden corp IT foundations (identity, device management, access) so security scales with headcount instead of lagging it.
Role Scope
Build the detection engineering function from the ground up: telemetry pipelines, detection content, alert routing, and response runbooks, with coverage you can defend against a threat model, not just a tool checklist.
Own detection-as-code end to end, writing detections across cloud and endpoint sources with tests, version control, and CI so a bad rule never ships silently.
Lead incident response for high-severity events, driving containment and root cause, and closing out each incident with detections that catch the same class of attack next time.
Drive automation of triage and enrichment in Python (or similar) so alert volume scales without proportional headcount.
Partner directly with leadership on security strategy, translating threat landscape and detection gaps into a prioritized roadmap with clear tradeoffs.
Work across corp IT and infrastructure teams to get the telemetry, logging, and access you need, and to fix the root causes your detections keep surfacing.
What We're Looking For
The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
8+ years in security operations, detection engineering, or incident response, with time spent at a high-growth tech company, cloud-native infrastructure provider, or top-tier MDR/threat intel firm.
You've built or scaled a detection engineering function, not just operated inside one: you can point to the program, the pipeline, and the coverage that exist because of you.
Deep hands-on experience writing detections against cloud telemetry (AWS, GCP, or Azure control plane and audit logs) and endpoint telemetry (EDR event streams, OS-level signals).
Strong scripting and automation skills in Python or similar, enough to build and maintain detection-as-code pipelines yourself rather than spec them for someone else.
Incident response experience at a company operating at significant scale, where you led response under pressure and your postmortems changed how the company operates.
You operate as a technical lead without heavy management overhead: you set direction, make the calls, and do the work.
You work well across corp IT and infrastructure teams in a fast-moving environment, and you get telemetry and fixes shipped by making the case, not by escalating.
Bonus: experience securing GPU clusters, HPC environments, or physical data center infrastructure, or contributions to open-source detection content (Sigma, community rule sets).
We are committed to pay equity and transparency.

The Security Team
Examples of key problems the team is working on
You're securing the frontier of AI. The model weights training on our infrastructure are the most valuable and most targeted artifacts in technology, and we're standing up the compute to hold them faster than anyone ever has. A breach isn't a leak, it's the frontier walking out the door.
Build the entire security program from scratch. Most leaders inherit someone else's system and spend a career patching it. Here you own it end to end, bare metal to boardroom, as we scale across continents.
Your threat surface is measured in gigawatts. The customers running on our infrastructure are building the most consequential technology in human history, and being responsible for the physical and logical security of that work makes everything else feel small.
Role Scope
Own security for the cloud and bare-metal control planes customers' training runs depend on: hardening, identity, and workload isolation.
Build guardrails as code: policies, scanning, and paved roads that make the secure path the fast path for engineers.
Engineer detection and response across cloud infrastructure, from API abuse to compromised credentials to tenant escape.
Secure the multi-tenant boundary where customer workloads, some of the most targeted in AI, share infrastructure.
What We're Looking For
The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
You've secured production cloud or bare-metal infrastructure hands-on, not just audited it.
You've shipped security tooling engineers actually adopted.
You've found and fixed real isolation or privilege-escalation issues.
You write production-quality code and treat policies as software.
You've run incident response on infrastructure you helped build.
Bonus: Kubernetes and container security. Hardware root of trust and measured boot. eBPF-based detection. GPU and HPC environments.
We are committed to pay equity and transparency.

Build network detection: telemetry, flow analysis, and alerting across training fabrics, OT networks, and the WAN.
Harden the OT and BMS side, where the network touches physical plant, against threats most security teams never see.
Automate network security controls so new sites inherit the architecture on day one.
What We're Looking For

You've deployed and tuned NDR or flow-based detection that found real intrusions.
You work infrastructure-as-code: your firewall rules live in a repo, not a GUI.
You've partnered with network engineering without becoming the department of no.
Bonus: OT and ICS security. Data center or cloud provider environments. BGP and routing security. Zeek or Suricata.

Role Scope
Run the security program's execution across physical, logical, and datacenter security, turning a fast-growing set of initiatives into tracked workstreams with owners, deadlines, and no dropped threads.
Drive cross-team security deliverables (bare-metal hardening, access control, incident response readiness, compliance evidence) to closure across engineering, datacenter operations, and IT.
Stand up the operating rhythm of the security org: reviews, risk tracking, audit and certification timelines, and the reporting that keeps leadership and customers current.
Quarterback security requirements into new site builds and customer onboarding so controls land before compute does, not after.
Own the metrics and status that show where the program is exposed, what is on track, and what needs an escalation this week.
What We're Looking For
The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
You've run technical program management for a security or infrastructure org, holding engineers and external partners to deadlines they signed up for.

You translate between security engineers and executives, distilling a sprawling risk picture into a decision and a next step.
You've coordinated incident response or audit timelines where a slipped date had real consequences, and you kept the trains running.
You track commitments, risks, and open items as a habit, so nothing critical lives only in someone's head.
Bonus: physical security or datacenter security programs. Model-weight or high-value-asset protection. Security tooling rollouts. A security certification (CISSP, CISM).

The Supply Chain Team
Examples of key problems the team is working on
Supply tens of gigawatts of compute, the largest build out of compute in history. Qualify and dual-source across every critical equipment category, with lead-time and capacity thresholds tied directly to the forward build pipeline.
Make supply chain the reason we build faster than anyone. Our modular build redefines speed in this industry, and it lives or dies on supply chain. Keep procurement permanently off the critical path so schedule compression stays our advantage, not our constraint.
Build the most accurate supply chain prediction modelling that exists. Use the frontier of AI to forecast lead times, demand, and disruption with a precision the industry has never had, and turn that foresight into a structural edge.
Role Scope
Own the consumables category: coolant, filters, spares kits, PPE, and everything sites burn through daily.
Set stocking strategies per site so consumables never idle a crew, without tying up capital in dead stock.
Negotiate national and regional agreements that give every new site pricing and supply from day one.
Build the replenishment system that reorders on consumption data rather than someone noticing an empty shelf.
What We're Looking For
The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
You've managed high-SKU-count procurement (MRO, consumables, spares) across multiple sites.
You've set min/max stocking levels from usage data and defended them against both stockouts and write-offs.
You standardize SKUs across sites so purchasing power consolidates.
You automate reordering rather than running it on memory.
Bonus: Data center or industrial MRO. Coolant and liquid cooling consumables. VMI programs. Punchout catalog systems.

Forecast optics demand from network designs and keep supply ahead of installation crews.
What We're Looking For
The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
You've sourced optics, fiber, or connectivity components at high volume.
You understand optics well enough (form factors, reaches, compatibility) to catch a spec mismatch before it ships.
You've qualified second-source components and managed the engineering skepticism that comes with it.
You track consumption against forecast weekly and correct early.
Bonus: 800G/1.6T optics markets. Cable assembly manufacturing. Interop testing programs. Commodity price hedging.
We are committed to pay equity and transparency.

About Fluidstack
We exist to make humanity more free. For most of human history, you farmed or you starved. Technology gave people more time for the things they wanted to do, instead of things they had to do. Powerful AI will be the biggest lever for human choice we've ever built - but only if models are aligned with what humanity actually wants. There are groups building AI who don't share these goals. Whoever deploys frontier compute infrastructure fastest will decide whether AI expands human freedom or shrinks it.
We're singularly focused on delivering 10 to 100s of GWs of compute faster than anyone else, rethinking every layer of the stack. We acquire power, design and build data centers, and operate them - with teams spanning hardware and software. Speed and scale are our key differentiators. Come be a part of building civilization-scale infrastructure for AI.
We hire people who care deeply about this problem space. If that is you, please apply!
How We Operate
Extreme ownership. Full autonomy. Own things end to end often taking on scope outside your core role without being asked to get things done.
Velocity. We drive everything forward as fast as possible.
First principles. Challenge every assumption. Zero analogy thinking, no egos, the best idea wins.
Love of the game. The frontier of AI is the most interesting problem of our time. We put in long hours at high intensity to push the frontier forward.
The Supply Chain Team
Examples of key problems the team is working on
Supply tens of gigawatts of compute, the largest build out of compute in history. Qualify and dual-source across every critical equipment category, with lead-time and capacity thresholds tied directly to the forward build pipeline.
Make supply chain the reason we build faster than anyone. Our modular build redefines speed in this industry, and it lives or dies on supply chain. Keep procurement permanently off the critical path so schedule compression stays our advantage, not our constraint.
Build the most accurate supply chain prediction modelling that exists. Use the frontier of AI to forecast lead times, demand, and disruption with a precision the industry has never had, and turn that foresight into a structural edge.
Role Scope
Own the steel category: structural steel and fabricated assemblies feeding the modular manufacturing line and site builds.
Source fabrication capacity across regional shops so throughput scales with the build plan, not with one shop's backlog.
Negotiate raw material and fabrication pricing with mechanisms that survive commodity swings.
Qualify fabricators on quality and capacity, and manage the load balancing across them weekly.
What We're Looking For
The below is a starting point. We always make space for exceptional people, so if you don't fit this role exactly, tell us where you would.
You've sourced structural steel or fabricated steel assemblies at industrial volume.
You understand fabrication economics: material, labor, coatings, and freight, and where each shop makes its margin.
You've qualified fabrication shops and caught the capacity overstatements in their pitch.
You manage commodity exposure with indexing or hedging rather than hoping.
Bonus: AISC-certified fabrication networks. Modular construction. Weld quality programs. Logistics for oversize loads.
We are committed to pay equity and transparency.
