Engineering Group, Engineering Group > Systems Engineering
General Summary
Join Qualcomm's Audio Systems Group and play a key role in the verification, validation, and analysis of audio codec technologies across next‑generation Snapdragon platforms. This role is initially focused on automated testing, continuous integration (CI), and data-driven analysis of codec behaviour and performance.
The role will also have a focus on interoperability (IOP) testing and deeper audio-domain work, requiring an understanding of audio signal processing, codec algorithms, and subjective/objective audio quality evaluation.
You will work closely with audio algorithm, systems, and platform teams to ensure audio codecs are robust, scalable, standards-compliant, and production‑ready across wearables, mobile, XR, compute, IoT, and automotive products.
Key Responsibilities
- Develop, maintain, and execute automated test pipelines for audio codecs and audio subsystems using CI frameworks (e.g. Jenkins or equivalent industry-standard tools).
- Design and implement functional, regression, performance, and stress test suites for audio codecs and related components.
- Analyse large volumes of test results and logs to identify defects, regressions, performance bottlenecks, and standards compliance issues.
- Investigate test failures through root-cause analysis, working closely with codec, DSP, and platform teams to drive resolution.
- Create and maintain test infrastructure, scripts, and tooling to improve coverage, scalability, and efficiency of audio validation.
- Document test methodologies, test results, and known limitations clearly and concisely.
- Perform interoperability (IOP) testing of audio codecs across devices, platforms, and ecosystems.
- Develop an understanding of audio signal processing fundamentals to support deeper analysis of codec behaviour and quality.
- Assist in objective and subjective audio quality evaluation, including comparison of reference and DUT outputs.
- Support analysis of bitstreams, packetisation, error conditions, and corner cases relevant to real-world deployments.
- Contribute to refining test strategies aligned with standards, specifications, and customer use cases.
Requirements
- Strong experience in software testing, validation, or analysis, preferably in embedded or systems-level environments.
- Hands-on experience with CI systems such as Jenkins or similar automated build and test infrastructures.
- Proficiency in Python for test automation, data analysis, and tooling.
- Solid programming skills in C/C++ for debugging and understanding codec or DSP-related code paths.
- Experience analysing logs, metrics, and audio data to diagnose issues and validate behaviour.
- Understanding of software development and debugging workflows in Linux and/or embedded environments.
- Ability to work across teams, communicate findings clearly, and drive issues to closure.
- Strong problem-solving mindset with attention to detail and test completeness.
Preferred Qualifications
- Experience testing audio encoders and decoders in production or pre‑silicon/post‑silicon environments.
- Exposure to embedded DSP platforms or real‑time systems.
- Familiarity with Qualcomm audio frameworks, SDKs, or development tools (advantageous but not required).
- Prior experience in validation, verification, or QA roles that transitioned into domain expertise.
- Basic to intermediate understanding of audio signal processing concepts.
- Familiarity with audio codecs (e.g. AAC, SBC, LC3, aptX, or similar).
- Experience with audio test and analysis tools, waveform inspection, or offline signal analysis.
- Exposure to codec standards, compliance testing, or IOP testing.
- Familiarity with fixed-point vs floating-point behaviour and its impact on signal quality.
Educational Qualifications
- Bachelor's or Master's degree in Engineering, Electronics, Communications, Electrical, Computer Science, or a related technical field.
