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.
