About the role
What to Expect
Dawn Industries builds software that watches industrial robot cells (PLC, robot, gripper, sensors), diagnoses faults with evidence an engineer can verify, and applies a fix only when a human approves it. You will own the model of the cell: the compilers that turn vendor engineering artifacts (controller programs, project exports, robot backups) into one structured, queryable representation, and the representation itself. Your output is what the AI layer reasons over, so its correctness and its provenance are the product's credibility.
We develop against real hardware in our own lab.
APPLICATION NOTE: No PLC, robotics, or manufacturing experience is required. Learning to read industrial programs deeply is part of the job.
What You'll Do
- The Big Picture: Build the compiler, and the representation it targets, for the programs that run the world's factories, compiled into one typed, queryable, provenance-carrying model that an AI can reason over.
- Format Parsing: Build parser front-ends for vendor engineering artifacts, each against real test projects: Siemens TIA Portal sources and Openness/SimaticML XML exports, Rockwell L5X/ACD, Mitsubishi GX Works projects, and robot controller backups (FANUC TP/LS listings, I/O configuration, registers, alarm history), with more robot languages to follow (ABB RAPID, KUKA KRL, URScript).
- Program Analysis: Parse and analyze IEC 61131-3 logic (SCL/ST text, LAD/FBD networks) to recover behavior: state machines and their transitions, fault raise and clear conditions, timers, guard expressions, and a complete read/write cross-reference.
- Representation Design: Own the schema: a typed graph of tags, steps, faults, interlocks, and cross-device handshakes that stays general across vendors.
- Deterministic Compilation: Keep builds byte-stable and re-runnable: canonical serialization, content-addressed versions, and diffs that distinguish a changed fact.
