Careers
Work on software that watches a melt pool at 240 frames a second.
Powdrix is pre-launch and building its founding team. The four roles below are the ones we expect to open first, written as honestly as we can about the stage: there is no office to show, no customer list, and the first job is a paid pilot on one machine.
Illustrative scenario: PBF-2 · Ti-6Al-4V bracket family, 24-part build, 23 of 24 parts released, one held
Founding roles
Where we need people
Role descriptions, not an openings count. Each is a founding role.
Founding controls and OT integration engineer
Printer, oven, HIP and robot-cell connectors. Parameter envelopes, bounded writes, approvals, rollback and the assurance-grade audit log.
Founding simulation engineer
Omniverse part twin, thermal and distortion simulation, physics-informed surrogates, cuOpt nesting and scheduling, synthetic scenario generation.
Founding AM process engineer
Someone who has qualified a part family on metal PBF. Translate parameter craft and qualification practice into envelopes, metrics and acceptance tests for design partners.
How we work
Six things about working here
The floor is the customer
We measure ourselves on scrapped builds, CT hours, coupon campaigns and idle machines, the floor's own numbers.
Nothing unlabelled
A design target is called a design target. A scenario is called a scenario. A cited standard is not a certification. We do not round up.
Qualification is a feature
The envelope, the approvals and the assurance-grade audit log are the product, not overhead.
Simulate first
A recipe is rehearsed on the twin before it is released. So are our own changes.
Write it down
Every decision, every run, every correction goes into a record someone else can audit.
Go to the floor
The craft we are encoding lives next to the printer. We go there.

Process
How hiring runs
- Write to us. What you would own, what you have built or qualified, and why this floor.
- A conversation. An hour on the problem, not a quiz.
- A working session. A real design question from the backlog, worked together.
- References and an offer. Founding terms, discussed openly.
Accelerated computing
Physical AI, at the melt pool
A build is thousands of layers and a day of machine time. Perception has to be local, deterministic and fast, CT has to be triaged in minutes, and the twin has to run before the build. Powdrix runs GPU inference at the printer edge and keeps training, simulation and optimisation in the cloud or on-prem.
Edge perception
One Jetson node per printer for 30 to 240 fps melt-pool, layer and recoater streams with photodiode and thermal fusion. Sub-250 ms alerting and 1 to 2 s bounded recommendations are the design targets. Jetson Thor is planned for multi-laser machines.
CT and vision inference
2D and 3D segmentation models for porosity, cracks, lack of fusion, surface defects and metrology comparison, served per inspection cell. Sub-15-minute CT triage per build is the design target.
Training
Defect, melt-pool-instability, build-failure and AM reasoning models trained weekly over multimodal build data, with gated promotion from shadow to assist to bounded. Dedicated capacity is planned.
Part twin
Thermal, melt-pool-proxy, residual-stress and distortion simulation for recipe ranking, plus robot-cell and queue simulation. Modulus surrogates are planned so sweeps run at production cadence.
Synthetic data
Rare pore, lack-of-fusion, spatter, recoat-streak and distortion scenarios generated and validated against real CT and in-situ data before promotion. 1,000 to 10,000 per qualified part family is the initial target.
Optimisation and analytics
Build nesting, fleet scheduling across machines, ovens, HIP, inspection and robots, energy windows, and GPU analytics over genealogy tables.
Robot handling and serving
Plate, powder and part handling policies trained in simulation and run on Jetson in the cell. NIM packages perception, prediction and reasoning services behind the floor orchestrator.
Autonomy
Four levels, set per agent and per machine
A qualified floor does not go from manual to unattended in one step. Powdrix makes the level explicit, auditable and reversible at any time, and human approval for anything that affects qualification stays mandatory until validation exists. The first release runs shadow mode, then assist mode, then graduated autonomy.
| Level | What the agent does | What the human does | Where it sits in a pilot |
|---|---|---|---|
| L1 · Advisory | Predicts and recommends, with citations; nothing is written | Enters every change manually | Shadow mode on one machine, first weeks of a pilot |
| L2 · Supervised | Proposes a parameter, thermal or inspection move; it executes on approval | Approves each move in the review console | Assist mode once accuracy is measured against CT |
| L3 · Bounded | Writes inside the OEM-approved parameter envelope and per-tag limits | Approves anything that leaves the envelope or affects qualification | Graduated autonomy on low-risk loops, if the floor is satisfied |
| L4 · Unattended | Runs the envelope without prompting | Sets the envelope; reviews the shift record | Planned; only after validation on the part family |
Guardrails
An agent that can trim laser power needs a leash
Powdrix writes to production printers that make qualified parts. Every capability is scoped to the qualified envelope, every write is policy-checked, and every action is written to an append-only audit log the floor owns.
- Bounded action space. Each agent writes only to an explicit allow-list of printer, oven and cell parameters, inside the OEM-approved envelope and per-tag rate and magnitude limits.
- Policy engine before every write. Autonomy level, part family, qualification status, machine state and operator presence are evaluated before a parameter moves.
- Human approval for qualification-impacting actions. Anything that leaves the qualified envelope, changes a validated recipe or affects a part's disposition waits for a named approver. This stays mandatory until validation exists.
- Immutable audit log. Append-only and exportable. Every action records model version, data lineage, source signals, predicted impact, allowed range, approval status and qualification impact.
- Hard fallback. Loss of the edge node, the network or a model returns control to the printer's own controller and the standing recipe.
- Tenant and IP isolation. Parameter sets, part geometry, defect libraries and process memory never cross a customer boundary. On-prem deployment is available for sensitive producers.

FAQ
Straight answers
The questions operations directors, process engineers and certification engineers ask in the first meeting.
Only inside the OEM-approved parameter envelope, only on an explicit allow-list with per-tag limits, and only at the autonomy level your floor has set. Level 1 is advisory: Powdrix predicts and recommends and a human enters everything. Design partners start there, in shadow mode. Anything that leaves the envelope or affects qualification always waits for a named approver.
Control returns to the printer's own controller and the standing recipe. Powdrix is a supervisory layer on top of the machine controls, monitoring systems and MES you already run, never a replacement for them, so an outage degrades the floor to its current way of running, not to a stop.
Advisory recommendations start from the twin's physics and the part spec in the first weeks. Defect and build-failure prediction improve as layers, CT results and engineer corrections accumulate per part family. The first models are trained on existing in-situ camera data; synthetic rare-defect scenarios augment them only after validation against real CT.
Only if you choose cloud training. Parameter sets, geometry, defect libraries and process memory are isolated per tenant and never used to train another customer's models. Cross-customer learning is federated and IP-isolated and waits on written data agreements. A fully on-prem deployment is available for sensitive producers.
It is designed not to. Validated parameters never change without the sign-off your quality system requires, model changes go through change control, and every action carries model version, data lineage, approval status and qualification impact in the audit log. Powdrix does not claim AS9100 or ISO 13485 certification; assurance packages are planned for the 6 to 12 month release.
You are, as with any process change, which is why every write is policy-checked, bounded, logged and reversible, and why anything that affects qualification waits for a named approver. The audit log records the request, the reasoning, the limits applied and the human decision.
