Senior AI Engineer

About Agaton

Agaton is the leading deep voice AI platform for enterprise sales and customer service teams. Our proprietary technology analyses every customer conversation, not just what's said but how it's said, surfacing the buying signals, unmet needs and churn risks in calls companies already make. We turn that into better conversations, making both human and AI agents measurably stronger, so teams drive more sales, stronger retention and higher quality.

Founded in 2024 by Andreas Kullberg and John Kristensen, Agaton has offices in Stockholm and New York, serving global brands such as Telenor, Axo Group, Telia, AIG and Tele2. The Agaton team previously held key positions at Google, Spotify, Salesforce, Slack and Tink.

Agaton is backed by Inception Fund, Alstin Capital and Sequoia Capital Scout Fund, alongside angels including Silo AI founder Peter Sarlin, HubSpot's Kieran Flanagan and King co-founder Sebastian Knutsson.

The Opportunity

As our Senior AI Engineer, you'll play a foundational role in building and scaling our production AI systems.

• Design, develop, and deploy production-grade, agentic systems, focusing on our autonomous agents and coaching engine.
• Collaborate with ML Researchers and Data Scientists to translate research prototypes into robust, production-ready AI features.
• Optimize the performance, latency, and cost-efficiency of real-time conversational AI agents in a production environment.
• Conduct code reviews, design documentation, and contribute to the overall software architecture of the AI systems.

What We're Looking For 🤩
