The Mission
GRAM is a self replication company creating populations of insectoids for the physical economy.
Our first research frontier is self-preservation: the base case of physical self-replication. Our machines will survive, coordinate, and recover without humans. We believe scalable machine labor requires more than single-agent task generality or machines shaped in our image.
About the role
You will own embedded software from microcontrollers and real-time control support through the Linux robot runtime. You will bring up new electronics; build drivers, deterministic communications, timing, health monitoring, calibration, logging, and fault response; and expose stable interfaces to higher-level autonomy.
Success means versioned embedded software produces known behavior on a known hardware configuration and remains observable, recoverable, and testable through degraded conditions.
What you will do
Design and implement C and C++ firmware, device drivers, hardware abstraction, real-time services, communication protocols, and robot-runtime components.
Define timing, bandwidth, lifecycle, state-machine, calibration, diagnostic, and fault-response contracts across sensors, actuators, power electronics, compute, and autonomy.
Bring up new boards and embedded compute using debuggers, oscilloscopes, logic analyzers, bus analyzers, kernel traces, and structured telemetry.
Build boot, provisioning, parameter, configuration, software-update, rollback, and recovery paths with explicit failure behavior and version compatibility.
Develop simulation, software-in-the-loop, hardware-in-the-loop, fault-injection, and regression tests that run automatically and gate releases.
Measure and improve latency, jitter, resource use, startup time, communication reliability, logging completeness, and recovery under load.
Investigate integrated-machine failures across firmware, Linux, networking, electronics, controls, and autonomy, then carry corrections through reproducible tests and release evidence.
Minimum qualifications
Bachelor’s degree in computer science, computer engineering, electrical engineering, or a related field, or equivalent practical experience.
Shipped C or C++ software on a custom electromechanical product using an RTOS, embedded Linux, or both, including direct responsibility for hardware bring-up or field failure resolution.
Implemented and debugged device drivers, interrupts, DMA, concurrency, memory ownership, and at least one physical interface such as CAN, EtherCAT, Ethernet, SPI, I2C, or UART.
Demonstrated real-time systems work with measured latency, jitter, bandwidth, CPU or memory use, and behavior under overload or component failure.
Closed a hardware-software defect using instrumentation and captured evidence, then added an automated test, monitor, or fault response that prevented recurrence.
Preferred experience
Robotics, autonomous vehicles, aerospace, industrial controls, or other distributed real-time machines.
Bootloaders, secure boot, over-the-air updates, Yocto, kernel or device-tree development, time synchronization, or deterministic networking.
Hardware-in-the-loop infrastructure, safety-related embedded systems, fleet configuration, or production programming and calibration.
The annual base salary range for this San Francisco Bay Area position is $165,000–$205,000. Health coverage, benefits, and generous equity come with the role. This role is on-site in the San Francisco Bay Area. A relocation bonus is available. We hire to start as soon as possible. We review what you’ve shipped; if it’s the caliber we seek, interviews take about a week, start to finish. We treat your work and conversations with discretion.
