Job Description

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

• Strong experience designing and bringing up embedded hardware: schematics, layout, power systems, sensors, and motor/actuator interfaces.
• Demonstrated ability to write robust firmware for real-time control on MCUs (e.g., STM32, ESP32, PIC, Nordic, TI).
• Hands-on debugging skills across oscilloscopes, logic analyzers, JTAG/SWD, signal integrity, and system-level integration.
• Comfortable working across hardware and firmware boundaries in fast-moving, interdisciplinary engineering environments.

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

Compensation

We offer competitive salary, meaningful equity, and benefits.
