At Fluidstack, we’re building the infrastructure for abundant intelligence. We partner with top AI labs, governments, and enterprises - including Mistral, Poolside, Black Forest Labs, Meta, and more - to unlock compute at the speed of light.
We’re working with urgency to make AGI a reality. As such, our team is highly motivated and committed to delivering world-class infrastructure. We treat our customers’ outcomes as our own, taking pride in the systems we build and the trust we earn. If you’re motivated by purpose, obsessed with excellence, and ready to work very hard to accelerate the future of intelligence, join us in building what's next.
Our Senior / Staff Site Reliability Engineers (Compute) are the backbone of Fluidstack’s platform. You’ll utilize deep systems expertise and software engineering to keep our bare-metal and virtualized compute fleet fast, reliable and cost-efficient at exascale.
Super-charge virtualization. Tune hypervisors (KVM/QEMU), kernel subsystems and NUMA layouts to squeeze micro-seconds off tail-latency for AI & HPC jobs.
Deploy & optimize at scale. Roll out new CPU/GPU nodes, validate SmartNIC and BlueField off-loads, and harden workload isolation.
Automate observability. Build kernel-to-orchestrator telemetry, incident-response bots and performance dashboards.
Root-cause the gnarly stuff. Lead crash-dumps, kexec/kdump analyses and performance regressions; turn insights into upstream patches and config templates.
Drive kernel & hardware collaboration. Pair with silicon and Linux teams to debug drivers, accelerate I/O paths and integrate emerging compute hardware (TPUs, DPUs).
Continuously improve. Inject chaos, run game-days and codify post-mortem learnings into SLIs/SLOs that matter to customers.
5+ yrs in compute-heavy SRE, kernel or virtualization engineering.
Mastery of Linux internals (scheduler, memory, drivers) and system-level debugging.
Production experience with KVM, Xen, QEMU, VMware or similar hypervisors.
Fluency in C, Go or Rust; solid Infra-as-Code & CI/CD chops.
Familiarity with SmartNICs/DPUs and kernel-bypass networking.
Proven track record scaling high-throughput compute or HPC platforms.
Competitive total compensation package (salary + equity).
Retirement or pension plan, in line with local norms.
Health, dental, and vision insurance.
Generous PTO policy, in line with local norms.
The base salary range for this position is $175,000 - $320,000 per year, depending on experience, skills, qualifications, and location. This range represents our good faith estimate of the compensation for this role at the time of posting. Total compensation may also include equity in the form of stock options.
We are committed to pay equity and transparency.
