Aptiv's passionate team of engineers and developers creates advanced safety systems, high-performance electrification solutions and data connectivity solutions so that automakers can bring advanced capabilities to more people around the globe. This is how we enable sustainable mobility and help to prevent accidents caused by human error.

We're hiring an Electrical/Electronics Engineer to design and develop our automotive products in the areas of Active Safety and User-Experience. This position is located in TCI.

Your Role:

The Senior Android Audio & DSP Engineer will be responsible for designing, developing,

and integrating the complete audio subsystem on Android Automotive-based

infotainment platforms.

The role involves Audio HAL customization, DSP pipeline integration, Audio tuning, and

end-to-end debugging across voice, media, navigation, and projection use-cases (CarPlay

/ Android Auto / Alexa / Voice Assistants).

Key Responsibilities

1. Audio Architecture & Design

• Design and implement Android Audio framework components (Audio HAL, Policy

Manager, and Routing).

• Integrate DSP-based audio processing pipelines (Dirana, Qualcomm AudioReach,

NXP SAF775x, TI TAS series, etc.).

• Define and maintain signal-flow architecture from source to output (Mic → DSP →

Speaker / BT / USB / Projection).

• Collaborate with platform teams on ACDB configuration, audio calibration, and

DSP firmware loading.

2. Development & Integration

• Customize Audio HAL (vendor/qcom/audio/hal) for automotive-specific routing

and new use-cases.

• Implement and validate A2DP, HFP, USB Audio, CarPlay, and Android Auto audio

Paths

Integrate voice recognition and ECNR (Echo Cancellation & Noise Reduction)

chains for Alexa / Google Assistant.

• Develop and tune audio post-processing algorithms:

o Volume Control, Tone Control (Bass/Treble), Loudness, Fader/Balance,

SDVC (Speed Dependent Volume Control), Limiter.

• Support multi-zone audio and ANC/VESS feature integration.

3. DSP & Calibration

• Work with DSP firmware and tuning teams to optimize signal processing flow.

• Manage ACDB / XML configuration files for device profiles and calibration data.

• Interface with Tuning Professional / AudioReach Graph Studio / Dirana GUI tools

for parameter tuning.

• Analyze audio latency, clipping, and distortion using tools like Audacity, REW, and

MATLAB.

4. Debug & Validation

• Perform end-to-end debugging across Audio HAL, DSP, and routing layers.

• Analyze logs: logcat, dmesg, AudioFlinger, and AudioPolicy traces.

• Use diagnostic tools such as QXDM, mandiag, and Wireshark (A2DP trace).

• Support system-level validation for voice call, media playback, projection, and

navigation mixing.

5. Collaboration & Documentation

• Work with SoC vendors (Qualcomm, NXP, TI) for platform-specific fixes and feature

support.

• Document audio routing diagrams, signal flow, and calibration data handling.

• Collaborate closely with System, Integration, and QA teams to ensure feature

readiness and stability.

Your Background

#Exp 8 to 12Yrs, Strong understanding of Android Audio Framework (AudioFlinger, AudioPolicy,

HAL).

• Experience with Qualcomm AudioReach / ACDB and NXP Dirana / SAF775x / TI

TAS / ADAU DSPs.

• Expertise in DSP processing blocks (filters, gains, equalizers, loudness, limiter).

• Hands-on experience in audio tuning tools (TUNE, AudioReach Graph Studio,

Dirana GUI).

• Solid knowledge of PCM / TDM / I2S / I2C / A2B interfaces.

• Good grasp of Bluetooth Audio (A2DP, HFP, SCO/eSCO, LE Audio).

• Proficient in C/C++ and Python for HAL and toolchain customization.

• Familiar with audio codecs and formats - PCM, AAC, SBC, MP3, WAV, FLAC.

Good to Have

• Knowledge of CarPlay and Android Auto audio integration.

• Experience with Alexa Auto SDK / Google Voice Assistant integration.

• Exposure to Noise Control, ANC, and ECNR tuning.

• Familiarity with MATLAB for algorithm validation.

• Awareness of A-SPICE / ISO26262 process compliance.

Soft Skills

• Strong analytical, problem-solving, and debugging skills.

• Excellent communication and cross-functional collaboration.

• Ability to guide junior engineers in audio path analysis and DSP configuration.

• Ownership mindset with focus on quality, performance, and deliverables.
