Senior Electrical / Firmware Engineer

About Grafton Sciences

We’re building AI systems with general physical ability — the capacity to experiment, engineer, or manufacture anything. We believe achieving this is a key step towards building superintelligence. With deep technical roots and real-world progress at scale (e.g., a $42M NIH project), we’re pushing the frontier of physical AI. Joining us means inventing from first principles, owning real systems end‑to‑end, and helping build a capability the world has never had before.

About the Role

We’re seeking a Senior Electrical / Firmware Engineer to design the electronics and embedded systems that power advanced robotics, automation, and experimental tooling. You’ll own board design, sensor / actuator integration, motor drivers, safety circuits, and real‑time firmware for deterministic, reliable operation. This is a hands‑on role with deep ownership across hardware bring‑up, embedded software architecture, debugging, and system integration.

Responsibilities

• Design PCBs, power systems, sensor interfaces, motor drivers, and embedded control electronics for robotic and automation systems.
• Develop real‑time firmware for MCUs, integrating sensors, actuators, communication buses, and safety interlocks.
• Handle bring‑up, debugging, calibration, and reliability testing of electromechanical subsystems.
• Collaborate closely with mechanical, robotics, and automation engineers to build robust, production‑ready electromechanical systems.

Qualifications

Above all, we look for candidates who can demonstrate world‑class excellence.

Compensation

We offer competitive salary, meaningful equity, and benefits.
