Senior / Staff Firmware Engineer

About Us

The American pharmacy system currently struggles to meet patient needs. Long wait times, overworked staff, and outdated infrastructure have compromised reliable access to essential medications.

We are addressing these challenges today. We are a stealth-mode physical AI company working on a robotic pharmacy product. We are not just conceptualizing the pharmacy of the future; we are building it now.

About the role

• Develop, test, and maintain embedded firmware for real-time motor control, dispensing sequences, and sensor acquisition on the Rmix hardware platform

• Implement communication protocols and interfaces between subsystem controllers, host processors, and cloud connectivity modules

• Write and maintain unit tests, integration tests, and hardware-in-the-loop test fixtures to validate firmware behavior against dispensing accuracy and safety requirements

• Debug and resolve firmware issues across the full stack from register-level peripheral configuration through application-layer state machines

• Collaborate with electrical engineers on hardware bring-up, contributing to schematic reviews and defining firmware-driven test coverage for new board revisions

Required Qualifications

• 5+ years of experience in firmware or embedded software engineering, with hands-on development across multiple product cycles

• Experience developing real-time embedded firmware for motor control, sensor acquisition, dispensing or actuation sequences, or similar electromechanical applications

• Proficiency in C and/or C++ for resource-constrained microcontrollers, with working knowledge of embedded Linux a plus

• Solid debugging skills across the full firmware stack — from register-level peripheral configuration through application-layer state machines and communication protocols

• Previous successful collaboration with electrical engineers on hardware bring-up, schematic reviews, and defining firmware-driven test coverage for new boards

• Experience writing and maintaining unit tests, integration tests, or hardware-in-the-loop test fixtures for embedded systems

• Strong documentation habits, with an emphasis on capturing interface specifications, state machine behavior, and known limitations
