Our custom chips accelerators and software stacks enable us to take on technical challenges that have never been seen before and deliver results that help our customers change the world.


In Annapurna Labs we are at the forefront of hardware/software co-design not just in Amazon Web Services (AWS) but across the industry. Our Chassis Software team is looking for candidates interested in diving deep into the different hardware technologies that power our Machine Learning servers and develop the software and firmware to drive support and sustain these technologies as they evolve though concept and manufacturing and finally take their place in our rapidly expanding fleet of cutting edge Machine Learning products our customers demand.


Key job responsibilities
- Provide Baseboard Management Controller (BMC) and Satellite Management Controller (SMC) software and firmware for Machine Learning Accelerator (MLA) servers.
- Continuously collaborate with other server and board software teams responsible for accelerator management firmware and other programmable logic devices.
- Work within the larger MLA Systems Software group to support development of mission-mode firmware exercisers for manufacturing and vetting and automation for qualification and deployment.
- Engage in new product development by participating in early concept design reviews schematic approvals offsite board bringup and laboratory-based testing.

A day in the life
The MLA Chassis Software team was formed to focus on board firmware primarily for mission-mode control of sensors and other board-level hardware. This includes debug testing qualification and manufacturing. We touch technologies from device drivers to the I2C infrastructure pervasive in the server and everything in between. We are not working on machine learning algorithms but rather we work on the physical systems (hardware) which execute and accelerate those machine learning algorithms. Data paths I2C and device control are our bread and butter. Some of us know what a Tensor is but really its not what we do.
