About the role
Platform owns the foundational software that runs on the robot itself: the layer between raw hardware and everything else we build. You'll drive our real-time control stack, our hardware abstraction layer, and the robot API/SDK that every other team (controls, perception, behaviors, ops tooling) builds against.
What they're looking for
- 8+ years in systems/embedded/real-time software engineering, with meaningful time in robotics, autonomous vehicles, or another hard real-time domain
- Deep C++ fluency and comfort reasoning about real-time constraints, latency budgets, and determinism
- Hands-on EtherCAT experience (master implementation, PDO/SDO, cyclic vs. acyclic data) or an equivalent fieldbus/deterministic networking background
- A track record designing clean hardware abstraction layers, backend-agnostic interfaces, and/or public-facing SDKs or APIs that held up across hardware revisions or product generations
- A bias toward architecturally simple, verifiable systems, and comfort pushing back on unvalidated assumptions in design review
- Bachelor’s Degree in computer science or related field

Job Title: Staff Robot Platform Engineer
Travel: 20%
Persona AI is building humanoid robots for the most demanding environments in heavy industry — shipyards, steel mills, fabrication facilities, and offshore platforms — performing welding, grinding, maintenance, inspection, and material-handling work that is dangerous, physically demanding, and increasingly difficult to staff.
We are backed by leading strategic and financial investors and engaged with global industrial leaders across Korea, Japan, the United States, and Singapore. Korea is the center of gravity for our early commercial strategy, anchored by relationships with the world’s leading shipbuilders and steelmakers. Our work spans both the robot platform itself and the systems, partners, and playbooks required to deploy it at scale.
We offer competitive compensation, a performance-based bonus, 99% employer covered medical benefits, early-stage equity, competitive PTO, and a company-wide paid winter break between December 24th and January 2nd.
You’ll shape technology that’s redefining the possibilities of robotics and human interaction.
