Fullstack Engineer

San Francisco - On-site

$140,000-$220,000

We're hiring a Full-Stack Engineer to join a fast-growing AI company that just announced a $50M Series B. The team is pioneering how audio data powers the next wave of AI -- already working with top AI labs and most FAANG companies less than a year after launch.

You'll join a small, highly technical team building the tools and systems that make sense of massive volumes of audio data used to train state-of-the-art models.

Think: complex data pipelines, real product impact, and a front-row seat to one of the most exciting frontiers in AI.

What You'll Do:

Ship full-stack features that thousands of users interact with daily.
Build scalable systems and data pipelines that process terabytes of audio data every day.
Deploy and evaluate LLM- and DSP-based solutions to help users uncover new insights from complex datasets.
Collaborate closely with researchers and operations to rapidly prototype, test, and launch new data collection interfaces.
Stay current with cutting-edge technologies across software engineering, data infrastructure, and machine learning -- applying them to real product challenges.

What We're Looking For:

2-8 years of product-focused full-stack engineering experience.
Experience at high-caliber startups or fast-growing tech companies.
Proven track record building 0-1 products that directly impact customers and revenue.
Strong full-stack web development fundamentals -- ideally with TypeScript, React/Next.js, Node.js, PostgreSQL, and AWS.
Strong communication and collaboration skills; thrives in fast-moving, high-ownership environments.

Bonus: experience in audio, speech, voice, or signal processing.

Audio AI is exploding -- and this team is defining the category. Joining now means helping shape the core infrastructure that powers the next generation of voice and speech applications. You'll work alongside top engineers and researchers, ship meaningful product fast, and be part of a company scaling from breakout to industry leader.

Apply now to join a rocket ship that's just getting started.
