## Job description

Company Overview

Ambiq is on a mission to enable intelligence everywhere — powering the AI edge revolution with the world's lowest-power semiconductor solutions.

Built on our proprietary sub- and near-threshold technology, our chips deliver multi-fold improvements in energy efficiency without costly process scaling. Since 2010, we've shipped over 300 million units to customers building smarter wearables, medical devices, IoT products, and AI-powered edge applications.

Our cross-functional teams span design, research, development, production, marketing, sales, and operations across Austin, Hsinchu, Shanghai, Shenzhen, and Singapore. We move fast, tackle hard problems, and create space for people to grow through complex, meaningful work that shapes the future of technology.

We're looking for self-motivated, creative problem-solvers who are eager to push technological limits and make a real impact in energy efficiency.

At Ambiq, we live by five values: Innovate. Collaborate. Focus. Learn. Achieve.

If that's you, join us — the intelligence everywhere revolution starts here.

Scope

As a senior radio software engineer at Ambiq, you will drive wireless software development for the Apollo Blue family and develop wireless software solutions (implement specifications, design software, and unit test). This role will work with different cross-functional teams to integrate and debug wireless components on the company’s platform. Perform code review, code optimization, refactoring, bug hunting, and bug fixing.

The successful candidate must be intimately familiar with OpenThread, have extensive experience in developing deeply embedded applications for wireless silicon, and be good at analyzing RF and firmware issues using an air sniffer, logic analyzer, etc. The person in this role will be responsible for scoping software development work, delegating tasks, identifying resource/technical gaps, and taking the initiative to tackle challenging technical issues by seeking support from across teams. Write technical documents, including white papers, architecture diagrams, modules, and API descriptions

## Responsibilities

- Develop wireless solutions and implement new feature development.
- Perform code review, code optimization, refactoring, bug hunting, and bug fixing.
- Assist FAE team in customer development issue support.
- Produce unit, functional, integration, and interoperability tests, including automating tests when advantageous.
- Work with Product Planning Team to understand system requirements.
- Work with validation and system test teams to triage issues and communicate their status to management.

## Requirements

- Bachelor’s or Master’s degree in Computer Science, Electrical Engineering or related field.
- 5+ years of experience with 802.15.4 technology, including Zigbee or Thread software debugging experience with sniffer tools and protocol analyzers.
- Familiar with engineering best practices: git version control, unit-tests, and continuous integration.
- Fluent in low-level software debugging skills using GDB, emulators, JTAG, and more.
- Expert knowledge of performance and power optimization.
- Experience with Zephyr.
- Peripheral protocols: I2C, I2S, MSPI, UART, PDM, TDM, etc.
- Experience with Bluetooth/BLE or RF tunning/calibration are a plus.
- Strong communication skills; excellent technical communication with peers.

## About Ambiq Micro, Inc.

## Company Overview
- **One-liner**: Ambiq develops ultra-low-power semiconductor platforms and system-on-chip (SoC) solutions that enable edge AI on battery-powered devices.
- **Entity Type**: Public (NYSE: $AMBQ, as of July 30, 2025)
- **Headquarters**: Austin, Texas, USA (with offices in Hsinchu, Shenzhen, Shanghai, and Singapore)
- **Founded**: 2010

## Core Business
- **Primary industry**: Semiconductor / Ultra-Low-Power Integrated Circuits / Edge AI Hardware
- **Target customers**: B2B — OEMs and device manufacturers building wearables, smart glasses, smart home devices, healthcare monitors, industrial sensors, and IoT products
- **Mission statement**: To enable intelligence (AI and beyond) everywhere by delivering the lowest-power semiconductor solutions on the planet.

## Products & Services
- **SPOT® Platform**: Proprietary, patented Subthreshold Power Optimized Technology that operates below 1V, delivering a quadratic improvement in energy efficiency vs. traditional designs. This is the core differentiator enabling complex AI at the edge.
- **Apollo SoC Family**: System-on-Chip solutions now in their 5th generation. Flagship products include Apollo510, Apollo510B, ApolloD Lite, and Apollo330M Plus. Designed for wearables, smart glasses, smart home, healthcare, and industrial use.
