Careers — San Francisco
"You don't code behavior.
You code the room."
Ocelus runs large-scale world simulations. We don't need people who watch graphs. We need people who can sense when a run is flattening or about to bloom — who notice more than noise.
All roles are based in San Francisco. Most require working on-site.
You will monitor systems running at scale. You will decide which ones have earned continued existence. Decisions are final.
Simulation Systems Operators are the floor-level stewards of Ocelus's world infrastructure. You watch runs — not graphs. You develop a feel for when a world is teaching and when it has gone flat. You maintain the ledger. You retire runs with care.
This is not a passive monitoring role. Operators at Ocelus are trained to sense the quality of a simulation's output: whether its agents are still generating novel behavior, whether the cultural density is increasing or collapsing, whether the run is worth the heat it costs. You will be wrong sometimes. You log why.
The ops floor runs continuously. You will work in 12-hour rotations with a team of 6–8. The ceiling is high; the air smells like new carpet and coolant. You will learn to love it or you won't last.

Operators are assigned 4–6 active runs at any time.
Emergent culture is the signal no one programmed for. You tend it. You decide what survives the frame.
Muse is the glassed-in row of rooms on Floor 5 where emergent culture appears inside simulations — sometimes, mysteriously, outside them too. We call it cultural residue: songs, games, half-traditions, rituals without rulebooks. These are signals the system wasn't programmed to produce.
Cultural Residue Analysts are responsible for detecting, documenting, and evaluating these events. You are not a researcher in the academic sense — you are a witness with judgment. You determine whether a cultural emergence is noise, artifact, or signal worth harvesting. You build the taxonomy. You write the notes that outlast the run.
Muse is small. There are currently four analysts. The role requires a particular temperament: you must be rigorous without being reductive. The things that matter most in this work don't fit neatly into a utility score.
You will lead the function that watches for the things no one designed. The most important work at Ocelus is often the hardest to explain.
Muse operates at the intersection of simulation science and cultural observation. The VP of Emerging Culture Mining is responsible for the entire function: the analysts, the archive, the evaluation criteria, and the translation of residue events into actionable findings for Orchard, Lyra, and the executive team.
This is a leadership role that requires genuine intellectual authority. You will be asked to justify the value of things that don't show up cleanly in a utility score. You need to be fluent in both the language of the runs and the language of the boardroom — and you need to know when to use which one.
You will report directly to the founder. You will sit in on Model reviews. You will be the person who says: this matters, before anyone else knows why.
Patterns from the runs don't travel alone. You decide which ones hold outside the frame — and what they need to survive the translation.
Orchard is where simulated patterns become usable knowledge. Harvest Stewards are responsible for the critical evaluation and translation process: identifying which behaviors, structures, or discoveries from active runs have cross-application potential in the real world, and shepherding them through the validation pipeline.
This work requires a rare combination of skills: scientific rigor, systems intuition, and a genuine tolerance for the strangeness of what the runs produce. Some harvests are logistical — a new data organization method, a queue-flow model. Some are stranger. All of them require a steward who can hold the original finding intact while testing whether it survives contact with reality.
The model learned how a block moves. You translate that to the people who live on it.
Lyra is Ocelus's civic infrastructure division — the team responsible for applying simulation-derived models to real urban systems: transit, pedestrian flow, energy routing, food access, public space design. Civic Flow Coordinators sit at the boundary between the runs and the city, translating what the model learned into language, proposals, and pilots that cities and municipalities can actually use.
This is not a purely technical role. You will spend significant time in the field: in city planning offices, at community meetings, walking the blocks where the model is already quietly operating. You need to understand what the simulation produced and be genuinely curious about the people it's supposed to serve.
We run cool. Immersion tanks, heat reused to the rec showers and district loops. You keep the heat in its lane.
Ocelus's compute infrastructure runs on immersion cooling — server sleds submerged in liquid, fans off, waste heat recovered and redistributed to the building's rec showers, the district heating loop, and the rooftop greenhouse. The Thermal Systems Technician is responsible for the physical integrity of this system: the pumps, the tanks, the heat exchangers, the demand-response protocols that allow us to participate in the city's grid.
This is hands-on infrastructure work. You will be in the basement. You will smell coolant. You will also be responsible for a system that directly enables what happens on every floor above you, and you will know it.
The ops floor is the heartbeat. You set the rhythm. You hold the standard when the pressure is on.
The Director of Operations is responsible for the entire ops floor: the operators, the rotation schedules, the retirement protocols, and the quality of judgment that the team brings to the runs. This is a role for someone who has operated at this level — who understands simulation systems from the inside — and who can now lead the people who do.
The ops floor is the operational core of Ocelus. Everything that happens in Orchard, Lyra, and Muse depends on the quality of observation that happens here first. The Director sets that standard.
