Software Engineer, Cloud Infrastructure

Job Overview

Fluidstack is seeking a Software Engineer, Cloud Infrastructure to join our Production Engineering team. We exist to make humanity more free by 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.

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 Production Engineering Team

Examples of key exciting problems the team is working on:

• Make tens of thousands of GPUs legible in real time: build the observability platform that turns raw telemetry into signal, from site-level health down to individual device and link.
• Build the control plane every team at Fluidstack depends on: replace one-off tooling with a stable, versioned API surface that covers unified machine management, actual state inspection, and distributed command execution.
• Make the system's view of itself always match reality: integrate fleet state as a machine-readable source of truth across provisioning, operations, and customer-facing platforms.

Role Scope

Own the observability platform. Build and operate the data pipelines, decoration and correlation engine, and healthcheck framework that make the fleet legible — from site down to device and link.

Define and build the API surface for infrastructure. Design the contracts between production infrastructure and every tool that touches it.

Build the production control plane. Unified machine management, actual state inspection, distributed command execution — and the Kubernetes-based infrastructure that underpins it all.

Own fleet state as source of truth. SLOs, site lifecycle state, and integration with internal infrastructure management and customer-facing operations platforms.

Land new hardware into the platform cleanly. ZTP, DHCP, DNS, artifacts — every new XPU generation and site integration goes through IaaS before production.

What We're Looking For

You treat toil as a bug. If something requires a human to do it twice, you build the thing that makes it not require a human.

You design APIs that age well. You've felt the pain of a leaky abstraction at scale and you don't repeat it.

You move toward ambiguity, not away from it. You walk into the fog, build the map, and explain it to everyone else.

You learn at a steep slope. You reach real competence in an unfamiliar domain fast.

You carry a pager without flinching. You run the incident, write the postmortem, fix the systemic cause, and move on.

You're fluent with AI tooling. LLM APIs, MCP servers, and agentic frameworks, and you drive Claude Code, Cursor, or similar every day.

You've shipped production services that other teams depend on at scale, and you're comfortable in any language using AI coding tools.

Bonus: Distributed systems and data pipeline engineering. Time-series observability stacks (Prometheus, Thanos, VictoriaMetrics). API design and versioning at scale. Workflow and orchestration engines (Temporal, Cadence). BMC/Redfish or hardware telemetry. Go, Python, and Postgres.

Salary & Benefits

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.
