About Fluidstack

Technology is the most important tool humans have found for improving the human condition, but it is not a default good. It is a lever for ideology.

Today the most powerful technology in history is being built: machines that solve problems better than humans can. The most important mission of our generation is to imbue AI with democratic values: error-correcting institutions, freedom of speech, individual liberties. AI trains and runs on massive compute clusters. Whichever ideology builds the infrastructure the fastest is the ideology that will endure. Democracy is delicate and won't survive this technology by default.

We hire people who care deeply about this problem space. If that is you, please apply!

How We Operate

Be a barrel. Full autonomy. Own things end to end, take on scope without being asked, no permission required to operate outside your core role.
Insane urgency. We drive everything forward as fast as possible.
Reason from 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.
Build something that actually matters. If you're going to spend your time, spend it on something that matters to the world.

The Facility Controls Team

Examples of key problems the team is working on:

Controlling datacenter power demand in real time while keeping equipment within its operating limits.
Integrating power and cooling equipment and on-site generation so they can be monitored and controlled together.
Automating commissioning tests that verify equipment behavior and record the results.
Automating software deployment and configuration as new sites and equipment come online.
Processing telemetry from facility equipment and serving current and historical data through reliable APIs.

You'll build the production services behind this work: telemetry pipelines, equipment models, control APIs, and test orchestration. Most of our services use Go, NATS, ClickHouse, Redis, and Protobuf/gRPC, and run on Kubernetes.

Role Scope

Build and own the services other teams depend on. Device integrations, telemetry pipelines, equipment models, and APIs need to work together across sites.
Design the messaging and state layer. Preserve ordering where it matters, handle consumers falling behind, and recover after a restart without losing data or applying an action twice.
Own the data contracts and engineering standards others build against. Make device identity, units, timestamps, and data quality explicit, and evolve schemas and APIs without breaking consumers.
Build the path from a control request to a confirmed result. Enforce authorization, deadlines, and equipment constraints, track state changes, and make retries safe.
Build observability that explains failures. Measure ingestion lag, dropped data, stale readings, query latency, and command completion so an operator can tell where a problem started.
Prove behavior across the whole system. Use unit tests, integration tests, and simulated devices to exercise failure and recovery before changes reach live equipment.

What We're Looking For

Experience building large-scale software systems, particularly systems that produce and process large volumes of data, is relevant.

You've shipped production code in Go, Python, or TypeScript, and you pick up whatever language the problem demands.
You have worked with high-throughput messaging systems such as NATS or Kafka. You understand ordering, delivery guarantees, backpressure, and the tradeoffs between concurrency and correctness.
You have designed data models for large volumes of time-stamped data. You can reason about slow queries and explain the tradeoffs between write throughput, query performance, retention, and schema evolution.
You have instrumented production services with metrics, logs, and profiling. You can show how that instrumentation helped you find a bottleneck or explain an incident.
You design before you build. You can explain the alternatives you considered, why you chose a particular design, and when you changed it because it stopped fitting the problem.
You define interfaces and failure boundaries deliberately. You know what happens when a dependency is unavailable, and your tests exercise those failures and the recovery path.
You have followed data from its source through services and storage. You account for missing, duplicate, late, and invalid data, and handle a stale value differently from a wrong one.
Bonus: Prior datacenter or controls experience.

Useful Experience

Our stack: Go, NATS, Redis, ClickHouse, Protobuf/gRPC, Kubernetes, and ArgoCD. Prometheus and Grafana for production observability.
Industrial protocols such as Modbus or OPC UA.

We are committed to pay equity and transparency.
