Intelligence Systems Engineer
Agents · Runtime · Evaluation
Design the runtime that makes agents employable: memory, permissions, tools, and the metrics that decide whether work is done.
Builders
We do not speak of a team as a family or a force. We speak of builders: people who can hold a long horizon without becoming vague.
Founder
Founder
Celestra began as a conviction: intelligence would become infrastructure, and infrastructure would need an architect. The work is to design that architecture — patiently, in layers, across decades.
To gather builders who can hold a long horizon without becoming vague, and to give them a company whose form matches the problem: one stack, many rooms, no theatre.
Values
We do not collect companies. We specify interfaces. If a venture cannot sit cleanly in the stack, it is not ours.
2050 is a design constraint. It makes today’s architecture stricter. It is not a costume for the present.
A system we cannot inspect, interrupt, or retire is not a product. It is a liability we refuse to manufacture.
Intelligence that cannot inhabit hospitals, markets, factories, and the racetrack is unfinished. The world is not a dataset.
We prefer the standard that survives a physicist and a lawyer in the same room. Fluency is a surface. Continuity is a structure.
Open positions
Agents · Runtime · Evaluation
Design the runtime that makes agents employable: memory, permissions, tools, and the metrics that decide whether work is done.
LLMs · Alignment · Evals
Train, compose, and refuse. Build models as a layer that can be versioned, measured, and withdrawn.
Perception · Control · Fleet
Give the stack a body. Close the loop between model and motor without leaving safety as a comment.
World models · Control · Assurance
Teach intelligence contact. Simulation that knows it lies. Policies that can fail without catastrophe.
Compute · Co-design · Energy
Specify the machine intelligence deserves. Workload truth from device to facility.
Language · Interface · Institution
Make the company legible. Typography, systems, and the few surfaces a serious institution is willing to touch.
No opening that fits. Write anyway. The stack is larger than the list.
