Real feedback loops
Your work is measured in prime yield and off-gauge metres, not in a leaderboard. The feedback is brutal and immediate.
Careers
Work that shows up in a coil
We are a small team building physical AI for one of the hardest control problems in heavy industry. If you want your model to change what a mill produces at three in the morning, this is the place.

Why here
What makes this different
The honest pitch, including the parts that will not suit everyone.
Physical AI, actually physical
Vision at line speed, physics-informed models, GPU inference at the edge, and a system that moves multi-tonne equipment.
Domain depth
You will learn metallurgy. Everyone here does. The engineers who ignore it build models that a rolling engineer dismisses in one meeting.
High autonomy, high accountability
Small team, few processes, real consequences. Nothing ships to a mill without someone's name on it.
Travel to plants
Engineering is in the plant during shadow and assist. If you never want to wear steel-toed boots, this is not the role.
Long horizon
Heavy industry moves slowly and then permanently. We optimise for being right in three years, not for a launch next month.
Open roles
Where we are hiring
All roles are hybrid with regular plant travel. Locations reflect proximity to design-partner sites.
Senior Rolling / Process Engineer
You have run a mill and can tell a model why it is wrong. You will own what correct means for gauge, shape and TMCP, and hold veto on anything reaching a line.
Computer Vision Engineer, Strip Surface
Line-speed defect classification on eight to thirty-two cameras per line, at sub-15 ms. TensorRT, DeepStream, and a lot of hard-won data work.
Control Systems Engineer
Model-predictive control for gauge and shape, integrated with Level-2 systems that were never designed for a second opinion. Rust or C++ at the edge.
Simulation Engineer, Mill Twin
Roll-bite mechanics, thermal evolution, flatness and microstructure in Omniverse, calibrated against real coil history until it predicts to microns.
Deployment Engineer
In the plant every week through shadow and assist. Part engineer, part diplomat, entirely responsible for whether a deployment succeeds.
OT Security Engineer
Own the control-path guards, segmentation and the architecture pack that OT teams review. IEC 62443 experience strongly preferred.
Process
How hiring works here
Four steps, roughly two to three weeks, no take-home longer than four hours.
- STEP 01
Conversation
45 minutes with the hiring manager about what you have built and what you want to build next.
- STEP 02
Technical deep dive
Two hours on your actual domain, with someone who does the job. No puzzles, no whiteboard trivia.
- STEP 03
Practical exercise
A scoped, paid exercise using realistic mill data — or a walkthrough of your own prior work if you prefer.
- STEP 04
Team and plant
Meet the team, and where practical, visit a design-partner line so you know what you are signing up for.
Benefits
What we offer
Straightforward, with the caveat that we are early.
Meaningful equity
Every employee holds equity with a standard, documented framework. No opaque terms.
Plant travel covered
Business-class on long-haul, proper per diems, and time off after intense commissioning weeks.
Learning budget
Metallurgy courses, IEC 62443 training, conferences — pre-approved up to an annual allowance.
Hardware you need
Workstation-class machines and lab GPU access. Nobody trains models on a laptop here.
Flexible hours
Mills run continuously; people should not. Core overlap hours, otherwise your schedule is yours.
Parental leave
[PLACEHOLDER] Policy documented and shared during the process; we do not publish a number we might have to revise.
Culture
How we actually work
Four practices that survive contact with a plant.
Small teams with clear ownership. Every deployment has one engineer whose name is on it, and that person can stop a promotion regardless of what commercial pressure exists.
Written first. Decisions with consequences get written down, reviewed and archived — the same discipline we apply to envelopes and objective functions in the product.
Metallurgists have veto. If a rolling engineer says a recommendation is wrong for a reason we cannot model yet, it does not ship. Deferring to domain expertise is not politeness; it is how you avoid destroying a customer's coil.
We say what we do not know. Internally and externally, uncertainty gets marked rather than smoothed over. It is the only way to be trusted with a hot mill.

Partners
Who you would be building for
“We ran Steelira in shadow for eight weeks on the tandem mill. It called eleven of the twelve off-gauge tail events before our AGC reacted. That was the moment the argument ended.”
“Our best roller retires in two years. Steelira is the first system that captured how he sets up a hard automotive grade — and then explained why, with the coil history to back it.”
“Prime yield moved 1.7 points on the galvanizing line and reheat gas fell double digits. Nothing else we bought this decade did both.”
