Job summary

The Ring Firmware team is seeking engineers to design and implement firmware for battery-powered and wired IoT devices running on microcontrollers and RTOS. You will own components end to end—from architecture through delivery and maintenance—while collaborating with hardware, cloud, and mobile teams to ship reliable products.

Prospective candidates should have professional software development experience, proficiency in Java/C++/C#, and hands-on work with RTOS, drivers, and CI pipelines in

Qualifications

• Experience (non-internship) in professional software development.
• Experience with an RTOS in a production environment: task design, inter-task communication, and synchronisation primitives.
• Experience implementing low-level drivers and interrupt service routines.
• Experience with testing discipline in an embedded context: unit testing, integration testing, or CI pipelines targeting embedded hardware.
• Experience owning a software component end to end, from design through to delivery and maintenance.

Responsibilities

• Design and implement firmware features for battery-powered and wired IoT devices.
• Review code, debug production issues, and work through trade-offs with your team.
• Own components end to end from design through delivery and maintenance.

A day in the life

You will spend your time designing and implementing firmware features, reviewing code, debugging production issues, and working through technical trade-offs with your team. New products bring new hardware, new constraints, and new problems to solve. The work is hands-on and the decisions you make end up in devices in customers\' homes.

About the team

The Ring Firmware team develops and delivers firmware for Ring\'s camera-centric devices across new products, existing device support, and new feature development. We are a large team with sites in Europe and Asia and stakeholders in the US.
