You will manage an in-production system, learn its architecture deeply, maintain fleet health, and extend it for new products and use cases across hardware, backend, and operations teams.

The role emphasizes ownership of the firmware stack, secure OTA updates, and collaboration with hardware and software partners to deliver

Qualifications

• Extensive hands-on microcontroller firmware experience.
• Experience with RTOS-based systems, interrupts, peripheral drivers, persistent state, and resource-constrained devices.
• Ability to bring up and debug hardware directly from datasheets, register maps, and protocol specifications.
• Experience supporting embedded product through production and after deployment.
• Understanding of firmware release safety, OTA updates, device recovery, and field-failure investigation.
• Strong bench-debugging skills.
• Experience taking ownership of a large, evolving codebase and improving it without stopping delivery.
• Sound engineering judgment and the ability to communicate clearly across firmware, hardware, backend, product, and operations teams.

Responsibilities

• Take technical ownership of the CR-One firmware platform and its build, flash, provisioning, release, and update pipelines.
• Safely extend and improve firmware running on devices in customer and partner environments.
• Own the OTA release lifecycle, including signing, staged deployment, rollback, health validation, and incident response.
• Diagnose firmware and hardware problems using logs, telemetry, serial traces, and controlled reproduction.
• Improve reproducible builds, release documentation, and operational visibility.
• Maintain backward compatibility across firmware versions, device configurations, and shared wire protocols.
• Support factory programming, provisioning, production testing, hardware revisions, and manufacturing failure analysis.
• Partner with backend and dashboard engineers on device configuration, telemetry, fleet health, and remote support.
• Help define the firmware architecture for future CR-One generations.
• Improve the system incrementally while continuing to deliver customer and partner capabilities.
