A Master's degree is a plus. * 10+ years of experience in system verification, quality assurance, hardware testing, software testing, or related disciplines. Experience in professional audio, wireless systems, RF electronics, or similar industries is strongly preferred. * Direct experience with professional wireless audio systems and/or RF products is highly desirable. Technical Expertise * Strong knowledge of UHF RF principles, wireless microphone systems, frequency coordination, spectrum management, TV band planning, intermodulation, and wireless deployment best practices. * Hands-on experience testing wireless transmitters, receivers, battery systems, RF performance, range, diversity systems, antenna distribution, and diagnosing RF issues such as interference, multipath, and dropouts. * Expertise in digital wireless audio systems, including digital modulation, error correction, latency analysis, dropout recovery, audio quality validation, and AES-256 encryption verification. * Strong understanding of microphone acoustics, including frequency response, tonal consistency, self-noise, dynamic range, SPL handling, and low-latency audio performance. * Knowledge of audio signal processing, including companding, A/D and D/A conversion, gain structure, DSP features, encryption impacts, and maintaining audio integrity. * Experience with networked audio and device management, including Dante, AES67, QoS, device synchronization, remote configuration, firmware updates, and troubleshooting Ethernet/TCP/IP-based audio networks. Testing & Quality * Proficient in functional, regression, exploratory, stress, reliability, and environmental testing. * Skilled at designing real-world test scenarios and evaluating complex interactions across RF, audio, and networking domains. * Experienced with professional test equipment such as spectrum analyzers, audio analyzers, oscilloscopes, and network analysis tools. * Proficient with defect tracking and test management tools (e.g., JIRA), with strong documentation and defect-reporting skills. Professional Competencies * Strong customer focus with a commitment to reliability, performance, and exceptional user experience in mission-critical environments. * Passionate about identifying defects, validating edge cases, and proactively improving product quality. * Demonstrated ownership, accountability, and commitment to continuous improvement. * Excellent written and verbal communication skills, with the ability to clearly communicate technical findings to technical and non-technical stakeholders. * Proven ability to collaborate effectively across Hardware, RF, Firmware, Software, Product Management, and Customer Support teams, using a data-driven approach to drive quality improvements. Applicants for this position must be currently authorized to work in the United States on a full-time basis. Shure will not sponsor applicants for this position for work visas. ## Description System Verification Strategy & Execution:Plan and execute comprehensiveend-to-end testingfor Shure'sProfessional Wireless Microphone Systems, coveringtransmitter-receiver pairs, RF links, audio pathways, DSP features, network/control interfaces, and broader ecosystem. Developdetailed test plansandtest casessimulatingreal customer workflowsinlive sound, touring, broadcast, theater, and corporate AVuse cases tovalidateperformance, reliability, and user experience under real-world conditions. * Quality Ownership & Defect Management:Act as theproduct quality championandvoice of the customerthroughout the development process.Proactivelyidentify, isolate, document, and track defects(with logs, RF spectrum captures, and audio recordings as evidence). Maintain astrong backbonein advocating for thetimelyresolution of quality issues, clearly articulating thecustomerimpactand ensuring priority fixes. Collaborate with cross-functional teams -Hardware, Firmware, Software (Wireless Workbench & mobile apps), RF Systems, Audio/DSP Engineering, Product Management, and Customer Support- to ensure critical issues are resolved before product release. * RF Performance & Wireless Link Verification:Rigorouslytest RF wireless performanceof professional microphone systems indense RF environments. Conductspectrum scanning, frequency coordination, intermodulation analysis, and interference simulationsto verify system resilience andcoexistencewith other wireless devices. Validatetransmitter and receiveroperation across diverse frequency bands, power levels, and regional regulations, includingwide-tuning ranges andHigh Densitymodes (when applicable). Performrange testing,multipath/droputscenarios, anddiversity/Quadversityperformance to ensure rock-solidsignal stabilityand coverage in large-scale events. * Audio & DSP Feature Testing:Verifyaudio quality and DSPfunctionalities across the wireless system. Measure and analyzeaudio performancemetrics (frequency response, noise floor,signal-to-noise ratio, dynamic range, total harmonic distortion (THD),latency, etc.) under various RF conditions to ensurecrystal-clear, low-latency audiooutput. Testmicrophone acoustics(capsule frequency response, polar patterns,maximumSPL handling) in lab and stage environments. ValidateDSP algorithmsand processing chains (gain structure, equalization, limiter/compressor behaviors, encryption, tone/key signals for squat switching,monitoringfeatures) to ensure all processing featuresoperatecorrectly and transparently contribute to superior audio quality. * System Integration & Networked Control Testing:Validatethe seamless integration of professional wireless systems within networked audio and control ecosystems. Testnetwork-enabled featuressuch asDante/AES67 digital audioand network control & monitoring viaWireless Workbench software,ShurePlus Channels mobile app, andShowLink remote control(forAxientDigital ADX transmitters) to ensure reliable connectivity, device discovery, firmware updates over network, remote monitoring, and control functionality (e.g., frequency coordination, real-time parameter adjustments, battery monitoring). Simulatemulti-system and multi-channel deploymentsto ensurescalability and interoperabilityacross multiple receivers and transmitters, and robust performance under heavy load or challenging network conditions. ## Related Videos - [More efficient software for more efficient microchips](https://www.wearedevelopers.com/videos/1164-more-efficient-software-for-more-efficient-microchips) - [Improving quality with Agentic AI with Rovo Dev and Xray](https://www.wearedevelopers.com/videos/2005-improving-quality-with-agentic-ai-with-rovo-dev-and-xray) - [An Applied Introduction to eBPF with Go](https://www.wearedevelopers.com/videos/1075-an-applied-introduction-to-ebpf-with-go) - [The Gashlycrumb Tinies of AI Networking You Must Know (or Languish!)](https://www.wearedevelopers.com/videos/2067-the-gashlycrumb-tinies-of-ai-networking-you-must-know-or-languish) - [Excellent Software Testing](https://www.wearedevelopers.com/videos/87-excellent-software-testing) - [Collaboration Quantified: Lessons from Open Source Developer Networks](https://www.wearedevelopers.com/videos/1422-collaboration-quantified-lessons-from-open-source-developer-networks) ## Related Articles - [The 8 Best Code Testing Tools](https://www.wearedevelopers.com/magazine/402-the-8-best-code-testing-tools) - [How We Built a Worry-Free System That Runs for 10+ Years – And What We’d Do Again](https://www.wearedevelopers.com/magazine/751-how-we-built-a-worry-free-system-that-runs-for-10-years-and-what-we-d-do-again) - [Should senior developers refuse interview coding challenges?](https://www.wearedevelopers.com/magazine/29-should-senior-developers-refuse-interview-coding-challenges) - [Fully Remote Software Engineer Jobs](https://www.wearedevelopers.com/magazine/447-fully-remote-software-engineer-jobs) - [The 12 Best Jobs for Software Engineers](https://www.wearedevelopers.com/magazine/401-the-12-best-jobs-for-software-engineers) - [How to Write a CV and Interview if You Don't Fully Qualify For The Job](https://www.wearedevelopers.com/magazine/183-how-to-write-a-cv-and-interview-if-you-don-t-fully-qualify-for-the-job)
