Data Scientist (Voice AI)

Deepgram is the leading voice AI platform for developers building speech-to-text (STT), text-to-speech (TTS) and full speech-to-speech (STS) offerings. 200,000+ developers build with Deepgram’s voice-native foundational models – accessed through APIs or as self-managed software – due to our unmatched accuracy, latency and pricing. Customers include software companies building voice products, co-sell partners working with large enterprises, and enterprises solving internal voice AI use cases. The company ended 2024 cash-flow positive with 400+ enterprise customers, 3.3x annual usage growth across the past 4 years, over 50,000 years of audio processed and over 1 trillion words transcribed. There is no organization in the world that understands voice better than Deepgram.

At Deepgram, we expect an AI-first mindset—AI use and comfort aren’t optional, they’re core to how we operate, innovate, and measure performance.

Every team member who works at Deepgram is expected to actively use and experiment with advanced AI tools, and even build your own into your everyday work. We measure how effectively AI is applied to deliver results, and consistent, creative use of the latest AI capabilities is key to success here. Candidates should be comfortable adopting new models and modes quickly, integrating AI into their workflows, and continuously pushing the boundaries of what these technologies can do.

Additionally, we move at the pace of AI. Change is rapid, and you can expect your day-to-day work to evolve just as quickly. This may not be the right role if you’re not excited to experiment, adapt, think on your feet, and learn constantly, or if you’re seeking something highly prescriptive with a traditional 9-to-5.

Opportunity:

Deepgram is looking for a Data Scientist (Voice AI) to take ownership of how we benchmark and evaluate the performance of our voice AI models. This role is pivotal to the integrity and impact of our AI offerings. You’ll be building robust benchmarking pipelines, producing clear and actionable model cards, and partnering cross-functionally with research, product, QA, marketing, and data labeling to shape how our models are measured, released, and improved. If you love designing evaluations that matter, aligning metrics with product goals, and translating data into insight, this role is for you.

• Build and maintain scalable benchmarking pipelines for model evaluations across STT, TTS, and voice agent use cases.

• Run regular evaluations of production and pre-release models on curated, real-world datasets.

• Partner with Research, Data, and Engineering teams to develop new evaluation methodologies and integrate them into our development cycle.

• Design, define and refine evaluation metrics that reflect product experience, quality, and performance goals.

• Author comprehensive model cards and internal reports outlining model strengths, weaknesses, and recommended use cases.

• Work closely with Data Labeling Ops to source, annotate, and prepare evaluation datasets.

• Collaborate with QA Engineers to integrate model tests into CI/CD and release workflows.

• Support Marketing and Product with credible, data-backed comparisons to competitors.

• Track market developments and maintain awareness of competitive benchmarks.

• Support GTM teams with benchmarking best practices for prospects and customers.

• Enjoy translating model outputs into human insights that guide product strategy.

• Are motivated by precision, fairness, and transparency in evaluation.

• Have a data-minded approach to experimentation and thrive on uncovering what’s working—and what’s not.

• Take pride in designing clean, repeatable benchmarks that bring clarity to complex systems.

• Get satisfaction from cross-functional collaboration, working with researchers, product teams, and engineers alike.

• Want to shape how we define quality and success in speech AI.

• Are excited by the idea of being a key voice in when—and how—we release new models into the world.

• Experience designing, executing, and iterating on evaluation pipelines for ML models

• Proficiency in Python and data analysis libraries

• Ability to develop automated evaluation systems—whether scripting analysis workflows or integrating with broader ML pipelines.

• Comfort working with large-scale datasets and crafting meaningful performance metrics and visualizations.

• Experience using LLMs or internal tooling to accelerate analysis, QA, or pipeline prototyping.

• Strong communication skills—especially when translating raw data into structured insights, documentation, or dashboards.

• Proven success working cross-functionally with research, engineering, QA, and product teams.

• Prior experience evaluating speech-related models, especially STT or TTS systems.

• Familiarity with model documentation formats (e.g., model cards, eval reports, dashboards).

• Understanding of competitive benchmarking and landscape analysis for voice AI products.

• Experience contributing to or owning internal evaluation infrastructure—whether integrating with existing systems or proposing new ones.

• A background in startup environments, applied research, or AI product deployment.

Don't have Voice AI experience?

You can still be a great fit if you are:

1. A detail-oriented perfectionist who takes pride in building precise, fair evaluations guided by products and is driven by accuracy, automation, and transparency in pipeline.

2. A collaborative systems thinker who excels at translating complex model outputs into actionable insights and building scalable processes that connect technical evaluation to business impact.

3. A curious, self-directed problem solver who thrives as a quality gatekeeper in ambiguous environments, enjoys cross-functional collaboration, and is energized by uncovering what works and what doesn't.
