About the role
About Symphony
Symphony is building voice AI sims for large enterprises. Use cases include training front-line employees and augmenting & automating customer-facing workflows.
Since launching in January, we’re live with 4 of the top 10 auto insurers in North America, helping train 1000s of newly hired claims adjusters using interactive voice AI simulations of real-world scenarios. Teams can create an infinite number of simulations allowing their teams to practice the job - avoiding costly mistakes with real customers.
We graduated from YCombinator’s F24 batch and are backed by top investors in Silicon Valley including 22 Ventures, Transpose Platform, and Rebel Fund.
What you’ll do
- Take full ownership of new product features — from scoping and user experience design to implementation across the frontend, backend, database, and infrastructure layers
- Refine and test prompts and build new agentic features, researching novel approaches to improve reliability of LLM-based functionality
- Collaborate with founders to scope, plan, and prioritize new features
- Lead engineering best practices and code quality standards, leveraging AI coding tools to accelerate development and maintain technical excellence
- Work directly with enterprise customers—from sales and onboarding to implementation and ongoing support—to ensure successful adoption and feedback-driven iteration
You’ll enjoy this role if you:
- Are excited to experiment with new features as LLMs unlock product experiences that require rethinking traditional UI and workflows
- Enjoy thinking through new features end to end, including scalability, extensible abstractions, data model design, and long-term reliability
