Embedded Software Engineer II, Ring, Ring

Ring is growing in Poland and we are looking for experienced Embedded Software Engineers to join our team in Gdansk. You will work on firmware for IoT devices used by millions of customers worldwide, developing new features and shipping products from concept to production.

As an Embedded Software Engineer, you will own the design and implementation of firmware subsystems running on resource-constrained hardware. You will work across the full development cycle: architecture, implementation, code review, testing on real devices, and production release. Our team operates with high autonomy and a strong feedback culture.

The ideal candidate:

• Has shipped embedded products to production and understands what it takes to go from prototype to millions of devices in the field.
• Writes clean, maintainable C/C++ for constrained environments and cares deeply about code quality.
• Communicates proactively, raises technical risks early, and drives solutions across teams.
• Thrives in a fast-paced environment where priorities shift as customer needs evolve.
• Is curious about the full stack, from hardware registers to cloud connectivity, and enjoys learning new domains.

The minimum base pay salary for this position is listed below. As a total compensation company, Amazon's package may include further pay components such as a sign on payment and the eligibility to participate in a restricted stock unit scheme operated independently by Amazon.com Inc. in USA. Your recruiting team will share final base pay and any applicable total compensation elements depending on skills and requirements. Company discretionary, supplementary benefits apply subject to further terms, including pension plans, health insurance, life and disability insurance, business travel insurance, MultiSport card, employee discount code and program (EDC/Extras), commuter benefits where applicable, and the Employee Assistance Program (private and confidential counselling and referral service to support health and well-being). The minimum base pay for this position is PLN 19,166 monthly.

Key job responsibilities

• Design, implement, and maintain embedded firmware in C/C++ for Ring devices.
• Specify and implement functionality for embedded subsystems (connectivity, streaming, power management, sensors, or security).
• Collaborate with hardware, QA, cloud, and app teams to deliver integrated product experiences.
• Participate in code reviews, technical design discussions, and cross-team architecture decisions.
• Debug complex issues across hardware and software boundaries using JTAG, UART, and protocol analyzers.

A day in the life
You start the morning reviewing a code change from a colleague working on a new sensor driver. After your team standup, you spend focused time implementing a feature for an upcoming product launch, testing it on real hardware at your desk. In the afternoon, you dig into a tricky issue that only reproduces on one board variant, tracing it from application code down to a register misconfiguration. You push your fix, verify it on the device, and close the day knowing it will ship to customers in the next release.

Basic Qualifications

• BA/BS degree in Computer Science, Computer Engineering, Electrical Engineering or related field, or equivalent practical experience
• Extensive experience in computer architecture and embedded wireless systems
• Extensive embedded development experience in C or C++
• Familiarity and experience with ARM CPUs
• Extensive experience with writing low-level drivers, interrupt service routines and general troubleshooting/debugging with hardware

Preferred Qualifications

• Master’s degree or higher in Computer Science, Computer Engineering, Electrical Engineering or related field
• Experience with one of more commercial wireless protocols like BLE or WiFi
• Experience in firmware development and testing of battery powered products
• Experience with development tools like IAR/Keil and Git version control system
• Experience with common bus protocols such as SPI, I2C, and UART
• Experience with software testing (unit, regression and system testing)
• Knowledge of embedded Linux and FreeRTOS
• Comfortable in some scripting language such as Python
• Experience in building GenAI applications
• Experience with AWS
