IoT Firmware Engineer: End-to-End Ownership & RTOS

Amazon Inc.; Cambridge; Presencial; GBP 70.000 - 110.000; Jornada completa

Descripción de la vacante

Ring firmware engineers are responsible for designing and delivering firmware for IoT devices, from architecture to deployment. You will own firmware components end to end and collaborate with hardware, cloud, and mobile teams to ship reliable products.

We value correctness, maintainability, and long-term health of the codebase, with hands-on work across hardware bring-up to production defects. Experience with RTOS and embedded testing is essential.

Formación

• Experience (non-internship) in professional software development.
• Experience with an RTOS in a production environment.
• Experience owning a software component end to end, from design through to delivery and maintenance.
• Experience with testing discipline in an embedded context: unit testing, integration testing, or CI pipelines targeting embedded hardware.

Responsabilidades

• Design and implement firmware for battery-powered and wired IoT devices running on microcontrollers and RTOS environments.
• Own components end to end: design, implementation, code review, testing, and maintenance across product generations.
• Define and implement software interfaces consumed by other teams and services.
• Debug and resolve issues across the full stack, from hardware bring-up through to production defects in the field.
• Contribute to and maintain CI pipelines, build systems, and automated test infrastructure.
• Work closely with hardware engineers, cloud engineers, and product managers to translate requirements into reliable firmware.
