Senior Product Quality Analyst - AI Voice

Spotify•Los Angeles, NY

3d•$114,486 - $163,552•Hybrid

About The Position

The Voice Production Team is the creative team behind Spotify’s AI voice experiences. We think about AI voices from a casting perspective — including voice type, age and gender — and from a performance perspective, recognizing that a voice may need to perform differently for DJ than it does for an audiobook recap. We bring expertise in voice casting, direction, recording and production, and work closely with Speak to set the quality bar for AI voice models across experiences including AI DJ, Generative AI Ads, Personalized Podcasts, Agent Voice Chat and more. As a Senior Product Quality Analyst, you’ll bring a dedicated evaluation perspective to the team. You’ll own how we define and measure AI voice quality, bringing together Voice Production’s creative bar, Speak’s technical bar and the wider industry bar. Your goal won’t simply be to determine whether Spotify has the “best” AI voice technology on the market. You’ll help us answer a more important question: is our technology the best at serving Spotify’s specific needs?

Requirements

Experience in product quality, evaluation, data curation or a closely related field where human judgment is used to assess model or product performance.
Ability to independently define evaluation criteria and turn subjective qualities into clear, repeatable rubrics.
Comfort designing and running both qualitative and MOS-style evaluations and synthesizing the results into actionable insights.
Understanding of voice or audio quality, including qualities such as naturalness, pacing, tone, accent and pronunciation, or the ability to develop that expertise quickly.
Strong judgment and ability to maintain a consistent quality bar while balancing different product requirements, markets and stakeholder perspectives.
Comfort working autonomously, identifying what needs to be evaluated and establishing the processes and cadence to make that evaluation useful over time.
Clear communication across creative, technical and product teams and ability to act as a reliable point of contact for internal partners and external vendors.
Curiosity about generative AI, speech technology and the evolving AI voice landscape and ability to translate changes in the industry into meaningful benchmarks for Spotify.

Responsibilities

Own the quality bar for Spotify’s AI voice models, defining what “good enough” means for different products, audiences, languages and use cases.
Independently design evaluation rubrics and build an evaluation approach that measures qualities such as naturalness, tone, pacing, pronunciation, accent, audio quality and overall experience.
Plan and carry out evaluation campaigns, turning qualitative and quantitative findings into clear recommendations for Voice Production, Speak and product teams.
Establish an ongoing evaluation rhythm, including when and how we reassess model quality as our technology and products evolve.
Benchmark Spotify’s AI voices against third-party models and competitors to understand where our experiences lead, where they differ and where there are opportunities to improve.
Help determine appropriate quality trade-offs as Spotify expands into additional languages and regions, considering the product use case and needs of each market.
Partner closely with voice experts, machine learning teams, product partners and vendors to maintain a consistent quality bar across demanding and sometimes competing priorities.
Surface the most meaningful gaps in model performance and use evaluation insights to help influence future research and technical priorities.
