Job Description

JD - Firmware Engineer (Audio)

We are seeking a highly experienced Firmware Engineer with 8+ years of hands-on experience in embedded audio software development, including Bluetooth audio, low-power design, and audio signal processing. This is a critical role in our hardware-software co-development team, where your expertise will directly impact the performance and user experience of next-generation AR/VR and immersive systems.

In this role, you will work on Bluetooth audio protocols, embedded DSP optimization, noise cancellation algorithms, and real-time streaming pipelines, while collaborating closely with hardware, product, and design teams. Your work will drive the core embedded intelligence of future-ready devices.

Top 3 Daily Tasks

Develop and optimize embedded audio firmware using C/C++, ensuring efficient performance, low power consumption, and real-time audio processing.

Work on Bluetooth audio protocols (A2DP, AVRCP, HFP), BLE profiles (HAP, TMAP, HAS, PBP), and audio codec integration (SBC, AAC, aptX, LC3).

Collaborate with hardware and systems teams to integrate microphones, speakers, amplifiers, and other peripherals via interfaces such as I2S, UART, and SPI.

Minimum Work Experience Required

8+ years of embedded firmware development experience with a focus on audio systems, Bluetooth communication, and low-level hardware integration.

Top 5 Skills You Should Possess

Strong command of Embedded C/C++, including memory management, real-time programming, and hardware abstraction.

Deep understanding of Bluetooth architecture, audio profiles (A2DP, AVRCP, HFP), BLE features (HAP, TMAP, HAS), and advanced Bluetooth technologies like Angle of Arrival (AoA) and Angle of Departure (AoD).

Hands-on experience with audio codecs: SBC, AAC, aptX, and LC3.

Familiarity with noise reduction techniques such as ENC (Environmental Noise Cancellation) and ANC (Active Noise Cancellation).

Proficiency with tools and methods for debugging, testing, and performance optimization of embedded systems.

You'll Be an Ideal Fit If You Have Experience In

Working with embedded Linux or RTOS-based environments.

Integrating Bluetooth stacks from Nordic (nRF52), Qualcomm (CSR), or Broadcom chipsets.

Handling audio streaming, buffer management, latency reduction, and audio quality assurance.

Bluetooth sniffing and traffic analysis using tools like Ellisys, Frontline, or similar.

Audio quality testing: Evaluating latency, jitter, and fidelity across Bluetooth audio profiles.

Power optimization and low-power system design for wearable/portable applications.

Working in Agile teams, using Git, CI/CD, and writing clear technical documentation and test automation scripts.

Full-Stack Awareness

While your primary focus will be firmware and embedded systems, awareness of system-level software integration, cloud/BLE connectivity, and app-level coordination will be a plus in delivering robust end-to-end solutions.

Bonus Points For

Experience working with beamforming, multi-microphone array processing, or spatial audio.

Familiarity with Bluetooth SIG specifications and standard compliance testing.

Exposure to AI/ML-assisted audio processing, such as smart noise reduction or adaptive filtering.

Involvement in multimedia or AR/VR hardware platforms.

What You'll Be Creating

You'll build the firmware backbone for next-generation AR/VR and immersive systems. From enabling crystal-clear, low-latency audio to powering intelligent Bluetooth features and noise-free communication, your work will be central to the user experience. Your contributions will support industries such as defense, healthcare, and enterprise training, where reliable audio is mission-critical.
