About Quin

Quin is redefining smart safety with real-time event detection and data-driven response systems that save lives. We embed our proprietary technology into helmets and wearables through B2B partnerships with global brands. With a strong foothold in motorcycling and a strategic focus on Cycling and Industrial Safety , our technology is already trusted by top names across the U.S. and Europe. We're a fast-moving, purpose-driven team building industry-leading technology that brings intelligence into safety gear.

About The Role

We're looking for a Firmware / Embedded Systems Engineer with 3 to 5 years of hands-on experience in embedded development to support the design and optimization of cutting-edge low-power, sensor-driven wireless devices. In this role, you'll be working on performance-critical systems involving BLE connectivity, real-time data processing, and custom hardware integrations.

This is a great opportunity for an engineer who enjoys digging deep into firmware performance, power optimization, and working across the entire embedded stack—from board bring-up to wireless protocols and sensor data management.

Key Responsibilities

Develop, test, and maintain embedded firmware for custom hardware platforms, with a strong focus on BLE-based communication systems.
Integrate and optimize sensors such as IMUs, accelerometers (digital and analog), and other low-power peripherals.
Work with flash file systems, bootloaders, and memory management strategies for efficient data handling.
Drive power optimization efforts across firmware, including deep sleep modes, peripheral management, and runtime tuning.
Contribute to antenna and RF performance optimization in collaboration with hardware and RF teams.
Support synchronized data collection across multiple devices for real-time streaming and data logging applications.
Collaborate with cross-functional teams including hardware, app, and data science to deliver seamless end-to-end product functionality.

Basic Qualifications

B.Tech. or M.S. in Electronics Engineering, Embedded Engineering, or related discipline.

3–5 years of experience developing embedded firmware in C / C++ for ARM Cortex-M or similar microcontrollers.

Proven experience with Bluetooth Low Energy (BLE) stacks and custom BLE services / profiles.

Experience with IMUs, accelerometers, and integrating sensor data into real-time applications.

Familiarity with flash memory, embedded file systems, and bootloaders.

Strong debugging skills using tools like JTAG / SWD, oscilloscopes, logic analyzers, and protocol sniffers.

Preferred Qualifications

Experience with Nordic Semiconductor devices and the nRF Connect SDK (NCS).

Knowledge of low-power design principles and techniques for battery-operated devices.

Background in RF / antenna tuning and wireless performance testing.

Understanding of BLE live streaming, synchronized data collection, and time-stamping accuracy across devices.

Familiarity with protocols like Find My, ANT+, or other proprietary wireless standards is a strong plus.

Exposure to both digital and analog accelerometers and their trade-offs in embedded systems.

Skills Required

Bootloaders, Antenna and RF performance optimization
